B24 1938

[Tomlinson]

I have just acquired a B24 frame and an old engine JB26.196.I think it is a 350cc.I need a big end /pin,piston,carb,magneto,dynamo ,pushrod tube ,clutch,fork pins, and lots of other bits.I have a couple of gearboxes but don't know what type  they are yet.Any old bits welcome to use as patterns.
Wheels seem to be rare.Can I fit bantam wheels until I get originals?
And loads of advice.

There's a Conrod/big end assembly on eBay from triumph twin spares but check rod number as there were a couple of different ones used for the 350. they may be interchangeable but I don't know, I think the difference relates to the size of the big end bearing.
Girder fork spindles, David Collwill engineering in Nottingham. He sells on eBay (or contact him direct) 1/2" unf studs in EN16T. He will make specials to order in terms of thread length etc.
The original B series girder fork spindles (bolts) are threaded 1/2" 20tpi cycle. To all intents and purposes from a practical point of view the two threads are interchangeable.
Once you have studs of correct overall length and thread length at each end they need a thin nut brazing on one end and the other end turning to replicate the groove for the circlip.
Same approach using these unf studs if wheel spindles are needed.
