to make a standard set would need 20, 40, 55, 60, 65, 80 and 100 for screwcutting... but any would do to give a bigger range of speeds for the power feed

I’ll see what I have in the magical pile of crap

Ok so I have:

1 off 50t

1 off 28t

1 off 55

1 off 80

2 off 65

1 off 90

1 off 100

1 off 75

What's the bore on those? Are they keyed or pinned?

Looks like you got most of a set there. If you need a 20 cut I could do one and perhaps a 60 too if you cut a blank. I just found someone selling a 14dp gear hob.

Will check tomorrow, I’ve just come back in. They’re keyed, although I had to open the bore a little bit to go on my Harrison L5A ( there was a 63t in the mix so snaffled it)

excellent - the only one I have from that list is the 50 so I'd take the lot if you have a price in mind? I've seen some 14dp gears with 22mm bore so I'm guessing that's what they are if you only had to bore the 63t out a little to fit the L5a?

Shoot me an offer my man, could be 22 off the top of my head but not certain.

I’ve always assumed they were off a very early L5
