engine sprocket...

...for mikes wl......so im making a sprocket with firstly a special offset to suit the new gearbox, secondly, one that will fit the standard wl crankshaft and thirdly will accommodate a duplex setup for the triumph gearbox.
heres part one...the original triumph crank sprocket.....and a section i machined up to fit the rear of that sprocket. im going to anneal the sprocket and then take out the inside section to allow me to fit nut home.
next im going to machine the standard wl sprocket to accept my spacer.....lengthy process ...maybe someone has done something similar and can let me know how they did it....

doing a simular thing to go 45 - bsa box. watching with interest. i was thinking of geting a custom sprocket made up from scratch rather than joining 2 with the offset. is the plan to seam weld either side of the sprocked onto the new spacer?

exactly......but getting it true is going to be hard.....ill have a go....if i cant do it then ill go another route.

I guess you'd have to press the assembly together in a lathe, hold it together with the tailstock and get it running true, then seam it together on the lathe.... Would be relatively easy if it weren't for the offset!
