Hello all you clever peeps,
I'd like to pick the collective wisdom:
Does anyone know what thread is on a Drummond round bed spindle nose? I have acquired a 4 1/2" 4 jaw chuck from that eBay, and now need a back plate to machine up & thread.
Also, where can I find a cast-iron back plate blank? I was thinking of finding some old training weights and turning one of those down, but I think the centre hole will be too big.
Cheers all,
Zed
