  • Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Ontario GTA West area meetup is planned for Saturday April 26th at Greasemonkeys shop in Aylmer Ontario. If you are interested and haven’t signed up yet, click here! Arbutus has also explored interest in a Fraser Valley meetup but it seems members either missed his thread or had other plans. Let him know if you are interested in a meetup later in the year by posting here! Slowpoke is trying to pull together an Ottawa area meetup later this summer. No date has been selected yet, so let him know if you are interested here! We are not aware of any other meetups being planned this year. If you are interested in doing something in your area, let everyone know and make it happen! Meetups are a great way to make new machining friends and get hands on help in your area. Don’t be shy, sign up and come, or plan your own meetup!

Hydraulic Lathe Tracer

More for visual FYI purposes (spendy) but these have always fascinated me. Basically you make a 2D pattern which is temporarily mounted relative to the metal blank. Then then the tracer mechanism basically copies it as you traverse the work. It a bit more complicated then that because you are making successive feed passes just like regular machining & that's where the hydraulic following comes in. I guess you could say 'analog CNC' :) Good for complicated or ornate work or even multiple copies of the same thing. Keith Fenner has some vids of his in action.

At one time I had a Harrison lathe bought from Modern Tool with a tracer we used it for the radius on english wheels.
 
Keith does have some interesting vids on those pattern followers. A Cnc refit to a standard lathe would cost about the same as these followers. Steppers, controllers, computer....
 
Sait threw there tracer lathe out 5 years ago but until then machinist apprentices used it to make bt40 tool holders. I rember thinking it was pretty cool but not in any way relivant anymore
 
pretty sure that was a McDougallbay auction item recently. Sask power sold off a couple of 13x40 lathes and that was one of the items up for auction.
