Mikes Indian Parts in USA got spacers from him Look at website All parts I've had from him very high quality and he easy to deal with

Only the early series B had cadmium plated steel footrest spacers. Everything from approx 1949 onwards had aluminium spacers. I don't know the exact changeover point.

My spacers are aluminum and have been on the bike since 1980, if not longer.
Thanks Bruce. My concern about the spacers was (a) do they squeeze onto the stud when tightened, and (b) doesn't the hole for the peg into the engine plate elongate, as it has on the steel ones I've seen?

Cheers Bill - my bike is 1949, late B, early C, so that'd be right, except that mine were stainless (home-made / proprietry?)

That's a catch 22......... The peg locates the hanger so it does not rotate, If it does .....people tend to over tighten the hanger nuts, thus it crushes the end of the taper onto the through stud.

Mine does tighten, but it is easy enough to tap the stud through. No problems with the peg loosening yet.

I have to really tighten the nuts up super tight (so yes the alloy will squeeze onto the stud) because I have had the hangers drag back whilst cornering and even still they can move. The right hand one makes it impossible to use the kickstart and the hanger movement tightens the nut further. The left hand one is dangerous because the brake lever can flip underneath and lift the rear wheel off the ground, plus the nut ends up being looser.

Does Peter Volkers have a cure for this?

Due to an unfortunate, and spectacular, accident a few months ago, I have got various parts from the Spares Co. Amongst these are both footrests and hangers, and to my consternation I find they are all made from cast brass!
Are you sure they aren’t bronze? If they are and they are made from the correct bronze, then should be fine. Or was it originality you were looking for?

I think you need to re-machine the tapers, as they should routinely tighten to the point that you need to remove with a mallet. You haven't got brass hangers have you - these would be more 'slippery'?

The footrest hangers are lead bronze, cast by a 'top quality foundry' (no connection to me but I know the manufacturer) and so should stand any normal treatment.

No the hangers are not brass. Thanks for the tip on the tapers.

Regulations and oxy acetelyne: Did I dream seeing it for sale in Bricolages in France and Harbour Freight in USA?
I belive the USA has it on offer you have real freedom there but if France has it then where is the EU level playing field?
MAPP gas methyl acetylene- propadiene propane is the one to use if you want a good heat. Readily available on ebay.

So how did the chrome look afterwards? My right hanger is a bit bent too and I have Oxy-Acetylene but have been reluctant to address it because of the chrome. The bend hasn't been a bother in riding but somehow does bother me when off the bike.
If your part was chromed before it bent, it will now be delaminated, as you would find out if you try to put it back to original. Chrome is not malleable.

Mike, I have a yellow metal footrest hanger. I inherited it with the project parts I purchased. I dont think it came from VOC Spares, it was too badly machined, they would not have let it through the quality system. It was during re-machining that I discovered the yellow under the zinc plating. In all fairness, it's not my favorite material for that job either, but it keeps my foot off the ground and provides a place for the brake lever to pivot.
I made alloy spacers because I have weight fetish & they are non standard length on my special. The tapers bite adequately, the pegs dont come loose and move at all.
Clearly, heating & straightening the original steel hangers has no deleterious affect on their metallurgy, they can then be safely re-plated.
What I haven't worked out with foot rest hangers yet, were the originals cast or forged?
Not that it matters, my next pair will be fabricated from steel machined ends welded to tube so I get some extra length.;)

Thanks timetraveller - good news, though I understood that lead bronze is a bearing material. Surely Aluminium bronze would be a better material

The re-manufactured ones are cast (in whatever), and pretty rough. Surely the originals were forged, as all this bending should have snapped even malleable castings! One of mine is severely bent, and the chrome appears to be intact, but we'll see, when I attempt to straighten it...

Of course Trevor is correct, chrome plate is not malleable, but I bent a footrest quite severely in 1974, the footrest had been previously chrome plated at Smiths Industries in Oxgate Lane, Cricklewood, at the time of the bending a helpful plumber lent me his gas bottle and blowtorch, and between the two of us we managed to unbend the footrest, that footrest is still on my bike to this day, with nice shiny chrome plate, very occasionally I do polish it, as yet there is no sign of it delaminating.

Yes, I assumed chrome won't accept much distortion. I did bend mine cold a very small amount and had no trouble with the chrome. But It's still not where I would like it to be.
So Peter, how hot did you get the hanger with the torch? Fully red?

On the other hand, maybe I'll live with it as it is.

Well it was 45 years ago when working on the Isle of Skye, but I seem to remember we got it reddish before pulling it back into shape, it has been fine ever since and as I say, the chrome seems ok, probably not concours standard, but good enough for me.
