Here is the old girl, 44 years old leaking petrol like a sieve, a small burn hole in the seat and no grab rail every thing else fine and dandy, patina is the order of the day for this one.

Here it is, build date June 1972, 5032 miles still got a lot of the yellow ink marks on the bolts from assembly, tank top faded, chrome really good only downside is a burn hole on the back of the seat, no grab rail and carbs hemorrhaging petrol which i expected, for this bike it's a clean up and run as is with it's 44 year old patina.

I very much doubt it, though at that price they should be made of stainless, i suspect they are knocked together in a very short period of time with the longest part being the plating up.

I know a little, i am a former metallurgical chemist, my last job within the industry was for a international rotogravure printing company that did everything in house, i came away in 2009 without any regrets as the plating game is so hazardous, i could only say London plating will do a good job as they are the only ones i had ever used apart from myself and i took care of any small parts as i had everything i needed at hand supplied free of charge, a nice position to be in at the time, these days i tend to buy new because wherever you go they are up against a mountain of regs, and to make it cheaper minimal amounts of everything goes on just to make it profitable.

No expert but I don't believe hard chrome is porous or anywhere as near porous as decorative chrome. Its done at very high current densities c/w decorative type.

Impressed with my Z650B stanchions done by Phillpots in the late 80's. They quoted me the same for a tiddler though as for CB500 stanchions, so not really economically viable on small bikes. On their stand at Stafford last year  they had some rechromed top nuts ...wasn't really impressed with the finish on those ! but as everyone says, their ground hard chrome is superb.

Tri - Hex no difference both are full of macro cracks so there is no waterproofing, the substrata for forks needs to be nickel and the decorative needs copper the higher the polished surface the the deeper the shine both tri and hex will give that lovely deep shine if preparation is spot on.

Wasnt twice the price in my case ie. Re-chrome £175 plus vat and new at £139 plus vat. Yes they were more expensive but the quality is way better than new, worth every penny....On the legislation front, I was referring to Hexavalent Chromium being banned for decorative chrome from next year, this does not apply to Hard Chrome as there are no alternatives. For decorative chrome they are being forced to use Trivalent Chromium which does not prevent rust or shine as well. The disposal and use of chemicals regulations applies equally to both types. Sorry for the confusion.

Neither trivalant or hexavalant will prevent rust, the shine will only be as good as the preparation of the sub strata, there is no confusion where the regs are concerned.

Philpots will rechrome them for about the same price as new. However, the rechroming will be far superior to the new ones and will still be in good condition in another 40 years. Also the legislation on chroming does not extend to hard chrome as their are no useable alternatives.

The legislation attached to chroming de-chroming apply to all aspects of the process regardless of decorative or hard chrome, health and safety disposal of wash off and processing of all waste within the industry is a costly business, it is nasty stuff that demands respect, and therefore drives up the cost, the last time i contacted Philpots the price of rechroming was twice the price of new stanchions'

As a rule these days it is cheaper to buy new stanchions rather than having them rechromed, the main problem now in this country with chrome plating is the legislation attached to the process making it harder and more expensive to stay within regulations, david silvers will sell the legs at a decent price.

Where's My Old Bike? / Brown Cb 500/4 k3 RGN114P

Anyone here know where it is now it was in Aylsford in Kent earlier this year, i was the first UK owner of this bike in the late 90's, at the time i put a boyer ignition system on it and replaced the exhaust's on it as it had a horrible 4 into 1 at that time, i also converted it to twin disc, i remember this one very fondly and in over 40 years on bikes it was the most reliable i have ever had.
