I'm thinking about further M20 machined parts at the moment..and will also consider parts for bikes other than the M20 if the demand is there.
Anything I do will be stainless steel if the original was plated as I feel it is a practical substitute for cad. plating when blasted...I'm very interested in what forum members think might be worth looking at...Viability for manufacture can be determined later..initially it is sensible suggestions I am after...things that are hard to find etc....though I need to be able to find original examples as patterns of course...
At the moment I am planning to make the gear indicator plate for the M20 and am considering wheel nuts, cylinder head bolts and a few other parts...Any suggestions?..Ian
Hi Peter...Thanks for your comments..I believe Dave Plumbs mate is making the rear wheel spindles for the M20..not completed yet though. For the bearing conversion do you mean the front wheel of an M20?..Rear wheel taper bearings can be replaced with a cheap and available modern equivalent...(brg.no. 30204)...
Replacement of the speedo drive components would require helical gear cutting, hardening and grinding facilities etc....Expensive and complicated to make, so really a non starter for small batch replication.
NOS Fork bushes are available from Russell motors, plus other fork parts...Ian
I'm on the lookout for front and rear hubs for a 1930s Matchless Model X, complete with axles, bearings, brakes and so on, if you fancy a real challenge next Ian?

I said sensible suggestions... . Though if you can get patterns I can put you in touch with a company that will make them...for a price...Ian
Sorry Ian, I thought that would be just a couple of hours work for you? I can't actually think of anything else I need at the moment, which is a fatal thing to say, something is bound to go bang now! I'm very surprised you haven't been inundated with suggestions for stuff.
I'm thinking of batches of parts rather than one off individual requirements..rather like the parts I have already made..I'm sure there will be a few things to do....Ian
There seems to be a dia shortage of oil filter caps part number 66-8358 & springs. When I spoke to Les at Russell's he said he has been asked for these several times & thinks that they perhaps got thown away when the owners where changing filters, such a cheap item, pressed steel but a neccessary piece, in my opinion.
I made one of those gear indicator plates from Stainless sheet & formed it over an old taper roller bearing outer race. happy with it for own use except stamping the numbers into the stainless took a surprising amount of effort & result was not ideal.
I do suspect a high reject rate at the factory of those as my original one has a slightly wonky 4 :D
Hi Fred...That's a nice job for a handmade home workshop improvisation...I have a few of the original discs and as you say there are definitely variations in the quality of the stamping.
I plan two changes which shouldn't have too much impact visually (if any)..I have a more accurate method of producing the disc itself and the numbers will be machine engraved, not stamped. (In the same font style)...Accepting the originals varied and there were accurate and inaccurate examples I'm thinking most people would like one of the accurate ones!....Ian

Can I assume that you have quoted the original taper roller bearing number 30204 here and the equivalent deep groove sealed Ball bearing would Be a 6204 2 RS? Or if we went to an angular contact Bearing so that a spacer was not required A 7204 2RS
Cheers
Hi Ron...30204 is the number for a modern taper roller that fits directly in place of the original bearings in the back wheel..Personally I have never fitted alternative bearings to the front wheel as I fitted some NOS ones and still have another pair I haven't used yet..Ian
Two British Pounds here in the UK Kevin... ...Do you mean the crankshaft shock absorber nut?...If you do, there is a tab washer (lockwasher) available for that purpose....Ian
Hi Ian, yep... I do mean the shock absorber. Yeah, I recall that there's a tab washer, but I have my crank nut on already and a locknut would allow me to avoid removing it, as I don't have an air wrench in my garage. Last time I needed to use an air wrench, it meant loading up the bike. A lock nut would allow me to leave everything in place.
I'll use the search function to find the tab washer number.
Don't worry Douglas...I have made a list as each posting has been made and I can consider each suggestion at my liesure...Some of the things aren't viable cost wise or because the demand would be miniscule..others are already available from Russells or Draganfly etc. and there isn't room for too many suppliers in a small market...However, some of the parts suggested will be viable and worth doing, particularly for those who don't mind (or want) a material upgrade to stainless or who can't get cadmium plating done and want a good, durable substitute for it....Ian
Don't have an M20;Got an Enfield WDCO and Ariel WNG running.
canvas grips ?
unplated saddle springs (that I can paint easier) ?
decent seat covers
The late lighting switch under the seat (and the press button one on the headlamp)
Bit late on this one I know, but how about 'conversion kits' of sufficient bits to alter front brakes from cable to cable and rod? Brass bar end caps - easy enough to make if you have a lathe, but if you haven't then...
As it happens I am just organising the loan of the front brake rod parts with a view to making some...Bar end plugs were cadmium plated mild steel so blasted aluminium or stainless would be more appropriate than brass. I may do some of these when I do the next batch of bars....Ian
Hi Jeff..I have made these before periodically..Once I have cleared the current batch of jobs I'll be making them again. Probably late June time..I'll put a posting on the forum when they are about to be made....Ian
I'm now looking with very little success, for a short pillion seat cover.
BirminghamtoBerlin.com were making canvas covers but no longer have any stock, Dave Plumb has no stock, can you help with this?
