W&S #4 information? & tks Rob

[gunsmith]

I have a #4 Warner & Swasey with a threading attachment. It uses mandrels that are pre threaded to the desired thread instead of changing gears. The one on the machine is a 4tpi. I am trying to find more of these. I think I asked this question once before and was not able to follow up on it. Can't seem to find it in searches but maybe someone can reply. There is also a gear arangement that can be changed but the proper mandrel would be better. I think someone also sugested making my own. Not a problem but there are probably bucket fulls of them holding doors open somewhere. Any help????
