  • As some of you know, I have wanted to stop managing H-M for some time. It's a tremendous strain on my personal life. I want to set up my own shop. In September, September 15, to be exact, it will be 8 years that Hobby-Machinist has been in existence.

    I have been training VTCNC to run things here. Dabbler is going to learn too. I feel that they are ready to start taking over the operation. I will be here to help in case they need, but I don't think they will. Tony Wells is and will be here also to consult with. I will be doing backups, upgrades, and installing addons. Other than that, I will not be around. I am leaving this place in good operating condition, and financial condition.

Hi all,

I recently acquired a chase screwcutting attachment for my 1940s-era B.C. Ames No. 3 lathe. My lathe is slightly more recent than the screwcutting mechanism is, and so I'm going to need to adapt the gear that rides on the spindle to match what I have. The adaptation is pretty straightforward (bore out the gear, cut a keyway, figure out some way of locating along the spindle), but I'd like to keep this as close to historically accurate as possible.

If anyone has one of these screwcutting attachments on their lathes - preferably my generation, but older lathes welcome as well - I'd very much appreciate any photos or other documentation you can share! Thanks very much.
