Restoration of Sandcast Frame 5369/ Engine E5479

<< < (13/23) > >>

Trigger:
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 !)

cheers  ... Ash

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

UK Pete:
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
