OK ..I know you think I am crazy but I did some more evaluation. Please don't mock me it's just my nature to fanny about like this .. done it since I was a sprog!
1st I topped up the epoxy, cured overnight on the top of my boiler, then I hooked the pin up to a small chuck and linked to a load cell/data logger. In one test I applied 21 kG and the badge was creaking a bit so I backed off. I then recorded a test and at 16kg the chuck pulled off the rivet but the bonded rivet was still intact. So looks like result!

Here goes Mick.. The scans were 15meg each ... wish James would show me how to .pdf them  ! I got an email from Bob the owner only last year saying the bike is still below 600 miles. Evidently the boss at Honda UK at the time, Roger Etchell (David Silver's mate  ... saw it during a routine Honda dealer visit and bought it for a proposed museum at Honda HQ in Chiswick that never materialised , the bike was then move to a Honda place in Nottingham and then sold off to Bob Heath. Roger now runs his own resto/parts company www.honda-classics.co.uk ...I got a 1/68 CB250SS original Owners Manual from him last year.

Attached results of the 'experiment'. Looks pretty good .. could do with more epoxy around the base of the rivet though. Please PM your address and I will send you a repair kit Nige. [ Guests cannot view attachments ]

The rivets are perfect and got lots of 'em .. exactly the right length, aluminium and diameter (3mm) with a flat bottom. Mixed the epoxy with ali filler and left on the boiler to cure adding a 3rd mount to a K0 tank badge !! abraded surfaces first and played a creme brulee burner flame over it to let the epoxy flow out.
Off to the boozer now will report back tomorrow morning.
Got loads of the two-pack epoxy but short of the fine alloy powder so can only spare enough for you for your 4 badges (if it works of course)

Agreed but the 500 miler only that Bob Heath (of visor fame!) got that was found languishing at Honda's HQ unloved must be the 2nd !

Many thanks Ash.
Never seen this technique used before but very interested. Can you let me know by PM or email? Thanks.
Nige.
\ Found the rivets (loads of them) I will try it out on a badge and let you know. If it works I will PM you & send you a few and a bit of the epoxy concoction. Ash

From what I can remember Mick, the brake plate and hubs are polished then clear lacquered. The engine cases are silver painted unlike the 350F where some covers were polished and lacquered.I reckon those iconic down-pipes will come up great once re-chromed. Amazes me how many 400/4's are still out there languishing in sheds etc..... seems people just couldn't bear to part with them.
One warning on cleaning up chrome with Oxalic acid. The process generates metal oxalates in the solution which are very toxic. My chemist mate looked in horror when I told him I was using oxalic acid for cleaning chrome. but I retorted 'Well it's in rhubarb leaves... so it can't be that bad'. He reckons if he requisitions any, he has to sign the poisons register. It's el cheapo on eBay though as 'wood bleach'.

You can get plastic chromed but not sure how much it would cost. I would estimate about £25

Why not bond some aluminium flat head rivets to them and then use standard fixings. I have some special industrial epoxy and ally powder filler you can bond them with. Trust me the bond will be strong if you mix it and cure it properly. Agreed K0 emblem sets mega expensive, don't blame you for wanting to keep originals. I think I have some of the rivets but they are at work, I will check tomorrow if you are interested.

I would try some thin but hardish foam rubber backed with carpet adhesive tape. I sticks like sh*t to a blanket if you get decent stuff with the fibres running though it and the foam/adhesive tape shoud be just the right thickness to give no real gap between the emblem and the panel. You can get foam tape with adhesive but in my experince its not as tacky. Luckily my 'emblems' still have the mounting points intacts. BTW those K0 emblems are actually brass and re-chrome perfectly... All I need to find is someone who is prepared to sell a very small amount of Honda 'Sunny Gold' paint for the side emblems.

What's the turn around time on the mentioned chrome platers. Been using Lancaster Bronze and they take ages to send stuff back. They have had the carb rubber bands (12) off my F2 for nearly five weeks now. That's ridiculous, I need a new chromer. Cheers all.
Depends how much you push 'em I reckon Roy. I left all my stuff with the guy in Hinkley and then discovered he had had my mates mudguard for 11 months and it took him two weeks to quote me, almost. But when I challenged him on the 'phone over timescales he got a bit huffy and quoted me a week ! Sure enough exactly a week later he voice-mailed me saying my parts were ready for collection. That was for two mudguards inc stays etc, a wheel rim and a set of handlebars. To be fair to him, my mates mudguard was a rusty old moth eaten thing, that, personally, I would have thown in the skip. The chromer told me had to keep building it up with copper plate in order to rechrome it properly and it was a labour of love to get it anything like decent. So in summary he who shouts loudest gets it done, in my experience. It's a mucky sh*tty business to be in, so hats off to 'em really. I have tried 'copy chrome' and it just doesn't look right on Honda's... anyone else tried it out? Ash
