Shop Made Lathe Duplicator

A few days ago I read a post with a picture of a shop made lathe duplicator on a Shopsmith. I want to say it was from Shipwright, but I don't remember if it was here or in one of his Lumberjocks posts. And now I can't find the posts/pictures I'm looking for.

Can anyone help me out? My searches are fruitless thus far.

The shop made lathe duplicator used the tool carriage and the tool rest, with the actual rest taken of. The duplicator attached to the tool rest arm, and slid along the ways on the carriage. There was a long board attached to the top of the headstock and the table on the other end that held the pattern. I think an Allen wrench was used as the probe that followed the pattern. Has anyone seen what I'm remembering. I'm hoping the guy who built it will chime in with some more pictures and details. I am interested in building one and it would be a good starting point instead of re-inventing the wheel.

"Shipwright" is correct, here is one reference:

Yes it was me, but I didn't make it. It came with a 10ER that I bought for $50. There are more photos of it in this thread: http://www.shopsmith.net/forums/showthr ... 889&page=2

I don't have much more but PM me if I can help.

Awesome - thanks everyone.

I guess I would have to change the design a little bit to fit a Mk 5. If I leave the Mk 5 tool rest loose to allow it to pivot closer to and away from the workpiece, it also leaves the tool rest height adjustment free. From Shipwright's pictures, that is different than the 10ER.

The 10 used a stop collar to set the tool rest height. A collar will also work on a M5/V if positioned on the 'threaded' post correctly.
