Chroming
mike the bike:
Now that sounds like a good plan, the chroming isnt too bad bur surface rust is showing. I'll go for that and see how it works out.

Roy, I am a former metalurgical chemist and plate line oppo, so I know a little, enough to get me by, it's a bit of a minefield, but in this game poor prep shows up massively on the finished job, and these clamps are not worth the time involved to re-chrome, the cost of the prep way outweighs the cost of new.

Kevski, I noticed that your location is just the other side of Boston from me. Did you move up here to work in a chroming firm ? Since I moved up from Kent I have found it hard in this area to find a good polishing/chroming company. I have found a good chromers in York but, they never like taking on jobs when polishing is involved. Yes, the money is all in the prep work and some of these old bike parts are past the prep stage, especially all the thin, rusty parts.

I am out of the game now, it's a very unhealthy business, in my last place we were only set up to plate certain shapes and sizes of work, if i wanted small stuff done i used to set up a small line in my lab and do my own any thing large like mudguards, stanchions and things of similar sizes easier to buy new or source decent second hand stuff, happy to be away from it.

Having spent many an hour de-rusting, de-painting and generally faffing about fettling my old Triumph over the last few years (still in a zillion pieces I'm afraid), the splendid Mr Roy Hall advised me to buy a Bench Rotary Polishing machine with Scotchbrite Rotary Discs to polish some of my CB750 K4 engine bits (I buy the discs from - www.thepolishingshop.co.uk whose service is excellent).
Over this last summer I have tried a variety of different grade Scotchbrite Discs and also a couple of Rotary Wire Wheels and I just wish I'd known how effective they were years ago.
Luckily I use the Polishing Machine mounted on a B & D Workmate - outside my garage - luckily because after a mornings work, there is a fine layer of dust and crap over everything within a 20ft range.....not recommended when you are trying to rebuild a bike inside - but that apart, the speed in removing baked on crud, and the quality of finish you can achieve are quite remarkable.
If you are contemplating a rebuild, then you'll find the relatively small outlay on a Polishing Machine and Scotchbrite Discs is a really worthwhile investment.........maybe as a Christmas Present - ho ho ho !

I'd ask Santa for one but I haven't got room to swing a gnat in my shed.
