Here goes for another restoration thread, i have another thread going for diecast 9574, which i will carry on with but at an even slower pace than it has been going at, for now the Sandcast takes priority and it will also take some of the diecast parts i had stashed
Here is the bike as i bought it, the head and barrels are off a later bike, there are no brackets or fixings whatsoever, just an incomplete bottom end of engine, frame, swingarm, wrinkle tank, oil tank, wheels, and a couple of beat up guards

(http://cb750sandcastonly.com/coppermine/albums/userpics/10004/2.JPG)
As you my well see there is a hell of a lot missing but hey beggars cant be choosers,
The parts i most need are carbs, head and barrels, 9 hole clutch cover, double cut front guard, complete front brake set up
First of all i was itching to get the engine apart, fully expecting to find all sorts of nasty surprises, firstly i removed the studs, never an easy job especially on a 45 year beat up old engine

Then the moment of truth, open up the cases

(http://cb750sandcastonly.com/coppermine/albums/userpics/10004/sandcast_008.JPG)
Well all i can say is thank you god, the inside is in perfect unworn condition, the only mess in there was a small mouse nest, all the bearings were oiled and smooth running, the crank and its shells look as good as a bike thats only done 100 miles 0% wear, all gear cogs intact, and best of all no nasty chain break damage to the casings,
I have to say i have never been so excited about a bike restoration like i am about this one, guys its official i have SANCAST FEVER , and i have got it real bad,
bye for now

You lucky lucky beggar
Looks like you've got your work cut out.
Mick
-
Pete, is this the one from Freddy the Frog?
-
Mick certainly have got my work cut out, but thats the fun tracking down parts from (mostly USA), and doing as much work on the bike as i can myself, this is certainly a restoration for the brave, it will be a fine motorcycle when its done
Graham, yes you got it right it is the one from fat freddy (will dawkins ) from classic bike imorts
-
Nice one Pete 8), I'm looking forward to this thread, you've got your work cut out on this one but like you say half the fun is finding all the pieces of the puzzle
make sure you post plenty of photos as you find / do stuff ;) cheers Mick.
-
Thanks Mick, there will be hundreds of pictures, again half the fun for me is getting as much up here in pictures for you guys to see
it helps to keep the interest alive, plus i can look back and enjoy, i still have my 69 diecast on the go at the same time , i wont be giving up on that, things will just go on ahead at whatever pace suits me , no point in rushing

Did 'Freddie' give you any indication of how he managed to find 4 sandcast restos at around the same time Pete? At least he also sells off engine parts from USA imports sometimes. Have you noticed D&K will only really sell the complete motors (well for Cb350 motors, not sure on others) with no indication on the true state of them internally other than the standard ' weather seized' and some decent external photos. I was talking to their guy Pete on the 'phone a while back and he say he can sell that type of engine for (CB350 twins) all day long for around 350GBP so why sell engines for parts. Looks to me like some will be a real bargain, others will be full of rust inside. But I can't a afford a 350 quid 'punt'. It would be a five minute job to remove the cam cover and the state of the cam/rockers would be a real good indication of the true engine state.
Cheers ... AshD

Yes will told me the story, not sure if its ok to spread on a forum i can tell you off air
DK is a lucky dipp i have had some real clean low milage parts from them, on the other hand i have had some total heaps of shit at the same price as the good stuff, on the whole i think they are ok, it is a lucky dip with engines, but other parts have good up close pictures so its a bit easier to determine
pete

Ok guys a bit more progress, i washed the crankcases in my parts washer, then pressure washed them, dried them in the oven , blasted them clean getting rid of all that thick black paint, then pressure washed them again, oven dried them blew them through with an air line, washed them in thinners and masked them ready for spraying

Pete, I seem to remember the inside of the cases had a yellow paint? to counter pourosity
-
As a patternmaker and supplier of castings it's nice to see a closeup of the cases.
there are internal paints available to counteract possible porosity.

There does seem to be an internal coating to the insides, i only cleaned off the outsides by blasting, the insides remain as was

those cases look a bit rough, get the dremell out and polish them smooth :D

Going well Pete
I can't even find the time to wash mine.
I only mended my speedo today as I was stopped by the Oinks the other day.

Crikey Rich - didn't realise what you did for the day job. Those Crosswaithe & gardiner re-creations are amazing....was chatting with the Solidworks rep about those guys recently and he said they were an amazing firm. Incredible whats tucked away in the sussex / kent countryside...

Pete, what paint did you use ? To save any trouble with the missis, it is best to buy an old oven from a second hand shop and put it in your garage/workshop. You could of got the dremal out and smoothed those casing's off o bit ;) ;) ;)
-
Bloody hell, Is she understanding or did you get castrated.
When i showed the missus the pictures I can't repeat what she said, ;D ;D

Looks more edible that what comes out of our oven

How did you hide the smell of the paint fumes Pete?
-
I was working on my honda chopper, and was reving it up with the door open and the house filled up with the smell of a bike running rich
which is a bad smell to have in the house, so she had a moan at me and went out, so when she came back there was a smell still lingering and she must have thought that it was the smelly bike and said no more,

I'm going to keep mine quiet by letting her eBay loads of my spare Honda parts on her own eBay account and letting her keep the winnings ;).
Chickening out on using her oven again though, I have found an old built in one at work to use. don't want to get a roasting for using hers :D

Pete I use exactly the same tactic to boil stuff on the hob Just don't use an Ali pan it's a dead giveaway.

Luckily my wife is very understanding and wasn't fazed by the smell.

That is the amazing thing, the oven was brand new and she didn't hesitate to let me use it for curing paint, definately a keeper.

When you think about it. It is only a lump of metal, just like a baking tray. Always be careful when doing heads, always replace the valve guide O'rings. And if you wish to splash out, you could put some K-liners in.

Just realised i have not updated this thread on here yet i have on the sandcast forum so i have copied it over
I had a few hours spare today so i got the frame out for inspection, well i have to say the frame is very solid, it is hard to believe that its 45 years old, frames dont stay in that conditition here in the UK
(http://cb750sandcastonly.com/coppermine/albums/userpics/10004/sandcast_012.JPG)

(http://cb750sandcastonly.com/coppermine/albums/userpics/10004/sandcast_010.JPG)
Anyway the only repair needed to the frame is the side stand bracket, it seems quite common for these brackets to get ripped off, usually by kickstarting the bike while standing on the footpegs with it on side stand
(http://cb750sandcastonly.com/coppermine/albums/userpics/10004/sandcast_003%7E1.JPG)
Out with the chisel and angle grinder and off with the remains of the old bracket
(http://cb750sandcastonly.com/coppermine/albums/userpics/10004/sandcast_004%7E2.JPG)
My new side stand bracket arrived , i have to say fair play to will from classic bike imports (the guy i bought this bike from) he kindly sent me a piece of frame with the bracket on , so i ground off the welds and got the bracket off and cleaned it up ready to weld on

Yes keep it coming Pete... spot on thread :). When I get my parts together for my K0 I will start a resto. thread on it and my 250K0 too. Nearly there with the bits for them now.
Funnily enough my '69 UK K0 had a very nice frame with hardly any corrosion. I had it power coated (sorry Kettle738 ! ) but my 400/4 was stove enamelled by the 'Nutter Brothers'. Going to smooth Hammerite my CB250K0 as I have some NOS stuff before they changed its formula.
Cheers .. Ash
-
Thanks Ash, talking about powder coating frames i think for our uk climate it is a good idea, i realise honda probably sprayed the early frames and very thinly at that
but i like the powder coated look, i have done my f2 and k0 with powdercoat, however i am undecided on the sandcast, perhaps i should spray it

I think I have read somewhere that the CB750's frames were coated with a very very crude early form of powder coating that's why there is the mysterious funny grey coating under the black. May have dreamt it though ::)

Hey Pete.
I would also like to join in with a congratulations on your new project. You have happily taken a lot of pictures of all your projects, unfortunately I did not and I regret it now because a part of the restaurant is also taking pictures and maybe help others.
Have you thought about were you are going to buy a new front fender to the Honda- Yamiya I'm even looking for a new front fender for my bike his is expensive but god repro..
Having written this into Google translate hope you understand this.
Only if you are interested I have a cam cover unfortunately cromed, and a brake caliper
Regards
Tony

Hi tony , I am on the look out for a caliper and front guard the yamiya front guards are to expensive,the ones from Vietnam are very poorly made, good secondhand ones are. Difficult to find so I will wait to see what turns up, I would be interested in your caliper let me know if its tokico 1 or 2 and how much you want,
It gives me great pleasure to photo every step of the restoration , and makes ne very happy that people enjoy looking

Don't agree on the Vietnam front fender Pete. I bought one unchromed and showed it to ChrisR and he said he would happily fit one to one of his bikes, so his endorsement was good enough for me. But you have to hassle 'Eric' that you want a good one and to take extra care. Those Yamiya ones are just a plain ripoff. Maybe it's because Eric thought I was a 'female' Ashley :-[ until Kerry on the SOOC put him right.

Hi Pete.
I've been out in my garage to see the brake caliper I was talking about but unfortunately it is a Tokico 8 I have not so good for your Sandcast.
I will check up with a few friends if they have a Tokico 1 or 2

Will do it over weekend. Mine is not chromed yet. If polished I was quoted 35 GBP to chrome it by Quality Chrome in Hull as there should be no prep work. I only wanted the blade undrilled but he sent me the lot. He hand makes them but told me he also has a press tool but it belongs to his Japanese customer who won't let him press them for a third party. Have not spoken to him since 2011 so will send him an email.
Cheers ..Ash

Thanks Ash appreciate it.

Thanks Ash appreciate it.
No Prob.. here is his amusing email to me :-[
Dear honda_four_rider,
Thank you Ashley
I will fix it now
I have a personal question I want to ask you, I hope you not offense it
are you a man or woman? because I see Ashley name.
I hope you not get mad at me. when I ask this silly question.
Thank you, and we appreciate for your business

Ash i bought one of his double cut front guards it came to me rusty on the underside
and major blemishes in the chrome,also it was obviously badly hand made and not even straight, i complained to him he promised me a replacement , this went on for a long time till it was too late to complain, he just played me for a mug,with no intention of sending another, i put this down to a bad experience, i suppose i could get it chromed again i managed to straighten it out myself

Hmm yes that's why I asked him to sell me it unchromed and he then started offering them to everyone unchromed. Must admit it was a bit rusty underneath but then again it was 'raw' metal as he calls it but spot on on the top and polished like chrome! Problem is Yamiya's repro's are unreasonably expensive and the ones on eBay are usually in the US and mega expensive too plus the usual 80 quid to get it here, what with the customs/shipping etc., plus at least 100 to get rechromed. ChrisR send one to the chromers that was original and good and the chromers polished the cut edges so much it was as thin as a razor blade and was scrap!
One idea I had before 'Eric' offered them and I even started doing it, was to chop two cut sections from a standard guard and tig weld it under the mudguard stays onto another cut down one, then dress up/fill etc with metal and have chromed. That double-cut guard looks so cool to me. I know it's a ridiculous obsession with me (unhealthy one at that) but a K0 just looks wrong without it. :(
I could ask Dave Silver if he can consider making them. He can only at worst say no. Also I will re-contact Eric and ask what his current production is like and take up your case with him. I will also email Kerry (KP) to see if he has had any joy as I know he buys them from him. He also makes HM300 NoNo pipes and I have photographs of them and Kerry's appraisal of them but again that was in 2011.
Cheers ... Ash

Got this PM from Kerry (KP) on the Sandcast site re Eric's Vietnam double cut fender , mudguard whatever.
Hi Ash
It all comes down to price. The best option is to simply pay the going rate for a double cut mudguard or buy one from Eric. I bought 2 and was perfectly satisfied with the product. I used them on my die cast bikes as the original ones were missing. Sure they are a little rough but, buy the fender without chrome and not assembled (as you did) and you really can't go wrong for the price Use an original set of frame supports and honda fittings and I doubt anyone could ever pick it. My view is he does a good job for the price and compared to Yamiya repop double cut, Eric's are bargains

It's what comes from emerging from that black , hole earlier this year. Really happy now and love my job now ::). Honestly, I really enjoy contributing here .. and I hate myself and other members here getting ripped off. This is by far the best forum.
Still need to photo my 'Eric' K0 fender 'blade' and post on here.. just been a bit busy this week.

I know what you mean about black hole , I am working hard to dig myself out mentaly and financially, trouble is when I get stressed I seem to work twice as hard and get nowhere which is real frustrating,, when u get the time I will post up a picture of my guard and also my attempt at making a ducktail ko seat
And yes you atre right this a bloody good forum, since I have been down a bit lately I have had 5 pm,s of support, what a great bunch of fellas you lot are

As you can see from my previous post i am tackling the blasting and painting of my frame myself,this is for two reasons, number 1 is i just dont trust anyone to do it with the same care and attention that i will, and reason 2 is i usually powdercoat but this de values the sandcast , it is a big no no when you speak to any sandcast owner restorer, oh yes there is a third reason , i do not have the money to pay someone else
Yesterday i thought this would be a doddle probably an hour or two's work, how wrong could i be, my blaster just was not getting through the two layers of paint very quickly if atal in places, so i whipped out and got some paint stripper, quick word of advise do not ever by nitromores stripper, its expensive and totally shit, it just would not lift the paint, so i was out side till 11 last night trying to scrape off soft paint with a stanley blade and then go over it with a scotchbrite wheel on the drill, this got a good deal of it off so this morning i did more scraping , more blasting and more scotchwheeling and ended up with a shiney bare metal frame, all i can say is thank goodness that is over
now i have the problem of finding a doner frame and getting the seat hinges cut off and welded on to my frame as some mother f--er ground them off, as well as the side stand bracket which i have just done
now with all this moisture in the air at this time of year it would be stupid to leave it bare metal, so i have sprayed it up with some rust preventing primer till i get the seat bracket situation sorted, that way it wont start rusting in a hurry, i also wrapped it in a blanket then boxed it up and have stashed it
Take a look there is absolutely no rust on this frame, the very light surface rust that was there came clean off with the blaster, so them two layers of awkward paint done the job, other than the ground off brackets you could not wish for a better 45 year old frame

Did notice that your blasting gun is small Pete. That would take a good 12 hours to do. A good paint stripper is a wire brush on a angle grinder, had some good results by doing it that way.
were the original sand cast frames stove enamel?
-
Trigger your right the gun is small really the whole set up is just too DIY, i eventually used the blaster to get to the awkward places and drill attachments to get the easy to get at parts, i got there in the end fella, as for original coating i have no idea, the thing is there was a coating on top of the original, and this had remained quite soft and so the sand just bounced off, i got to say i am well happy now that stage is over and done with

Can't fault your determination Pete ,Brilliant.

I stripped a sand cast frame about 10 years ago and the front part was stove enamel but, the rest was a black paint over a orange/red lead base primer. I stove enameled the frame in the end because i could not find what it should be.

Hi Pete, So the engine was a real good 'un and likewise the frame, so all that tosh from people on SOOC saying it was a basket case was rubbish. Jealousy probably ::) So glad for you mate. It's always a risk buying 45 year old stuff and there are loads of sharks out there but sounds like it's come good for you. I must agree that I was crapping myself leaving my rare K0 frame with someone else.
I think people are mixed on powder coating. Kettle738 hates it but ChrisR always uses it, for sake of durability plus he actively rides all of his bikes including sandcasts. I did read somewhere, but probably dreamt it in reality ::), that the CB750 was coated in a really early form of powder coating, and there is always a strange light-grey coating under the 'paint' on the unmolested frames I have seen. There was a guy from Leeds on our cruise propping the bar up every night and turns out he owns the largest powder coating company in Leeds. As soon as I told him I knew about powder coating, he filled me in on all of the technicalities. He says he's got abrasive blasters but also a chemical dipping plant that will remove powder coating. He told me that the process is over well over 50 years old, which surprised me. Sadly, he had also just latched onto a dodgy Glaswegian couple who were totally pi**ed and the guy pinched my wife's ar*e, so I backed out of what was an interesting conversation :( Should be able to trace him though (the powder coater guy, not the Glaswegian !)

Yes your right ash the two most important parts of the sandcast are the frame and engine and yep thank goodness they are real good, the rest of the parts crop up all over the place, as you know my finance situation has stopped me buying any big ticket items , like chrome and other bits but there is no excuse for not getting stuck in with hard restoration work myself, so that is what i am doing, i had so many pm's from people on the sandcast site and over here saying just buy the sandcast or someone else will and you will regret it , to be honest i had in my mind already committed to buying it , i dont listen to the negative comments , i know what i like and want in life , i still get excited when i think of how my sandcast and K0 will come out eventually, now that is an illness ha ha
As for spraying the frame verses powder coat , there is another element you have to consider, for example whatever surface the baster leaves is what your going to get on your finished frame , for example my k0 frame must of had forward footrests or crash bars at one stage of its life, where they fix to the frame the clamps were over tightened and left indents in the frame, these are clearly visible as are many other marks, where as if you do yourself there is the chance to perfect the finish if you require
What did your wife say when he pinched her arse LOL

Well it's funny cos another guy had just pinched the Glaswegians wifes ar*e and for some reason she had had a go at the guys wife using the dreaded 'C' word, which my wife can't stand, so Cathy (my wife ) walked away and then got here own pinched. She writes plays so it all went down in the little book.
My K0 frame is still bare if you need any seat bracket measurements but I guess you can get these off your K0 anyway.
Cheers ... Ash
-
Thats funny about ash ;D ;D ;D ;D ;D ;D ;D
i contacted will about the brackets but the frame he has is on ebay and i cant justify the asking price for two small brackets,
richard is going to look into making up the brackets, so i will see how that pans out, and he will be able to take measurements from his k0 hopefully

Inspection of a 1969 sandcast swing arm pivot assembley

As you can see from my previous post i am tackling the blasting and painting of my frame myself,this is for two reasons, number 1 is i just dont trust anyone to do it with the same care and attention that i will, and reason 2 is i usually powdercoat but this de values the sandcast , it is a big no no when you speak to any sandcast owner restorer, oh yes there is a third reason , i do not have the money to pay someone else
Yesterday i thought this would be a doddle probably an hour or two's work, how wrong could i be, my blaster just was not getting through the two layers of paint very quickly if atal in places, so i whipped out and got some paint stripper, quick word of advise do not ever by nitromores stripper, its expensive and totally shit, it just would not lift the paint, so i was out side till 11 last night trying to scrape off soft paint with a stanley blade and then go over it with a scotchbrite wheel on the drill, this got a good deal of it off so this morning i did more scraping , more blasting and more scotchwheeling and ended up with a shiney bare metal frame, all i can say is thank goodness that is over
now i have the problem of finding a doner frame and getting the seat hinges cut off and welded on to my frame as some mother f--er ground them off, as well as the side stand bracket which i have just done
now with all this moisture in the air at this time of year it would be stupid to leave it bare metal, so i have sprayed it up with some rust preventing primer till i get the seat bracket situation sorted, that way it wont start rusting in a hurry, i also wrapped it in a blanket then boxed it up and have stashed it
Take a look there is absolutely no rust on this frame, the very light surface rust that was there came clean off with the blaster, so them two layers of awkward paint done the job, other than the ground off brackets you could not wish for a better 45 year old frame

Hi Martin there is a guy on here Called rich (RGP750), he has kindly agreed to make me some hinges , using his K0 as a template, he even mentioned about making a fitting jig so i can weld them in the correct place,
Just out of interest is your frame a scrap frame?
pete

I hope not took me ages to find a frame even a k2.Dont canablise for the sake off it.
Cheers
Bitsa

The frame has had a poor weld repair to right hand rear hanger area.
Could be fixed, but I dont have V5 for it, so could be used for parts unless someone fancies taking on a project?

Martin
Thats fair enough mate good for you to offer your services
Cheers
Bitsa
-
Yes thanks for the offer martin, just for the record i would never chop a good one up, thats abuse
pete

Martin, if you definitely want to shift the frame I'd be interested, if so can you tell me what you want for it?
Thanks, nigel.
-
To shift paint on large metal parts just use a stiff circular wire brush in an angle grinder!......it takes some time and effort, its very noisy and the vibration is a pain (literally) but it certainly shifts paint rapidly. Obviously you need safety goggles, respiratory facemask, ear defenders and thick gloves, and plenty of fag/ coffee breaks but just watch that paint shift. I have beasted a tank, frame, swinging arm, mudguards etc with an angle grinder and it beats paint stripper every time.....just need to do it outside and watch where the sparks are flying. I suppose blasting is just as good but an angle grinder costs nowt!
-
I stripped the front hub from the sandcast and my k0 today and i cant believe the quality of the original chrome bits from the hubs take a look they are amazing for original 1969 parts, no need for re-chroming

It's amazing how good the original chrome can be on Yankee bikes.
My bike from Colorado is totally rust free just a little faded but the one from Virginia is pretty grotty

Have you sorted your hinges yet Pete I picked up this seat today with the parts you need. :D know idea why there bolted to the seat.

Hi all i have got moving on the sandcast project again, i had a fellow sohc enthusiast (richard RGP750) kindly heiped me out and made me up some hinges which i welded on the other day, the welds are deliberately rough to match the rest of the 1969 welds on the frame which tbh are shocking
(http://cb750sandcastonly.com/coppermine/albums/userpics/10004/002~7.JPG)
Once lined up using a jig richard made me from his frame i welded up and primed
(http://cb750sandcastonly.com/coppermine/albums/userpics/10004/008~7.JPG)
Then i hung the frame up and sprayed the bugger myself, i just dont trust other peoples work and have had to many disappointments in the past, it has come out great and the gloss level is a perfect match for an original NOS footpeg which i used for reference, a couple of bloody fly's landed on the drying paint so i have that to deal with but that is easily done,
(http://cb750sandcastonly.com/coppermine/albums/userpics/10004/sandcast_005~5.JPG)
(http://cb750sandcastonly.com/coppermine/albums/userpics/10004/sandcast_008~3.JPG)
(http://cb750sandcastonly.com/coppermine/albums/userpics/10004/sandcast_006~3.JPG)
So i have the battery box, tool tray, footpegs, and swing arm to do next, then i can crack on with other bits, it would be nice to get the engine done , so i will report back with the progress on that when i get stuck in

Nice work Pete. Glad to see your back at it again. See what you mean about the welds. Looks like your going to need to raise some cash for the Sandcast, you may have to sell that F2 exhaust your hiding away. ;D ;D

Splendid job....glad to see you back in the swing and getting another 'Old Lady' back to her former glory.

Looks like i'll be bringing my frame up the weekend Pete.
Great looking job, Glad your'e back
Rich
-
Thanks guys
I have tried several paints , and made a decision that the nearest i could find to the old honda finish is hammerite, yes i did say hammerite, it is a f---cking useless paint when it comes to coverage you have to build up so many layers, the trick is buy a tin of black smooth thin it with 2k thinners and spray it firstly with thin misting coats then a couple thick
It takes forever to dry but i won't be using the frame for a good while so i will hang it up in a warm place and let it set, if after all that it turns out no good then i can always blast it off and start again, but saying all that it is drying quite well
pete
-
Nice one Pete as I found a full 2.5l tin of that stuff in one of the skips after the floods we had in 2013.. bl**dy tin wasn't even rusty so God knows why they chucked it away.. well my gain. What primer did you use? I have a few tins of Upol etch primer but I don't know about compatibility with Hammerite smooth. Suppose I could try a bracket out first.
Cheers
-
You may be lucky with an old tin Ash hopefully it was made before they cocked up
the formulation,it is pretty s**t now unless as Pete says 50 thin coats and a day at 90 degrees to dry.
Good luck
-
The big selling point about the old formula hammerite and smoothrite was the fact you did not need primer or undercoat, just wire brush loose rust off, and apply, used it more than 20 years ago on an old garden bench with wrought iron ends, still holding up well, can't vouch for the new formula (E.U. approved ) which I understand is sh#t
-
The upol etch primer is good and when i welded the hinges on that is what i used on that area, the rest of the frame was done with zinc 182 primer
The finish on hammerite is superb if you can get it on ok, as rich says the formula is shite now it seems to lack pigmentation and so needs many coats

The CB250K had mega thin paint anyway Rich ;D, so it will be bog standard then ;D ! How do I tell if its old or new formula?
A new guy at work's best buddy owns a large refinishing outfit, perhaps they will bung my frames in their oven. seem to remember I fixed something for him once, and I wouldn't take payment.
-
You'll know Ash
If you spray it and the part goes black it's the old good stuff if you have to spray it
5 times and it still doesn't look black it's the new stuff ;D ;D

I had a go at restoring my sandcast caliper today, i stripped it degreased it sanded out any scratches then sprayed it up , the caliper and the arm are silver the pivot bracket is polished and clear coated as per original, i have to say i feel really satisfied with the results, i shall dig out my new parts and rebuild it all tomorrow
