My Lathe Duplicator

I’ve been asked several times about my lathe duplicator, so today while I was turning legs I thought of it and took a couple of pics.

First off let me say this, I didn’t design the duplicator. I had a friend bought one just like it back in the 80’s. He had had it for a few years, I wanted one like it and set out to order one. The company he bought his from had gone out of business and the duplicator was no where to be found, so I had a machine shop to make one like his for me, or as close as they could get it. The duplicator has no markings or names on it so it was impossible to find another one like it to purchase.

I can turn the cutter around to the other side when one side gets dull if I don’t won’t to take the time to sharpen it. It’s tough steel and I’ve been using both ends of the same cutter since I’ve been using it, a lot of years.

The stylus on the bottom is mounted where it can be easily adjusted in and out and up and down to work on a template, same as the cutter.

The duplicator slides on a set of rails attached to the bed of the lathe. I’ve got two lathes the duplicator is used on, both HF. One bought in 1990 that I paid 90 bucks for plus shipping from California. I don’t think HF sells this lathe anymore but for 90 bucks, it’s turned 100’s of table legs, kitchen island legs and spindles and still going.

When I bought my new HF lathe last year, I had to have a set of rails made that would fit it that the duplicator would slide on and work with a template. It too has already turned many legs with no problems. You can see both the duplicator and the rails in the picture. The leg on the lathe was the last of 24 I had to turn to make 6 farm tables alike to go in a restaurant. The legs are popular and took me about 20 minutes on each one of them with the duplicator.

I found out, years ago, that if I turned the leg round first with a regular turning gouge, the duplicator worked twice as fast and twice as smooth and easier to turn a leg.

Very interesting.
Where did you get the cutter for it?

I’ll try to do an update tomorrow and show how it all works. The cutter was made by the machine shop also as was the complete duplicator, Very hard steel,

I thought maybe it was one of those cutters from HF.
But some closer pictures would be helpful, as I am interested in making one.

I had breakfast with some of my local woodworking buddies this morning and all but one of them had one made just like it also, two had made their own. Never knew that or had forgotten it. We all agreed it was probably ahead of it’s time because back in the 80’s, no internet nor forums, and not that many machines and tools made for the home woodworker.

This one is heavy, and I would think much easier to control against anything turning on a lathe. Our youngest daughter is out of school today and is using it to turn Shaker knobs out of Curley Maple for a tall cabinet she’s building.

Because of the way the stylus and cutter are adjustable, one template can serve just about any size turning project. The stylus screws forward and back to control depth of cut as does the cutter also. Both ends of the cutter are machined. When one side gets dull, turn it around and use the other end. The steel is so hard it a chore just to sharpen it,

Stylus and cutter set to neutral. I use this setting most of the time. When I use a template on a narrower leg I’ll have to move the stylus forward to keep from taking to much wood out of the smaller leg.

Just a few of the many templates we have. Most of them go back years and have been remade several times. You want to get a template as perfect as possible. Any imperfections will show up on the turning project. On our larger commercial lathe in our millwork shop sometimes detailing will have to be done with a regular chisel, never had to do that with this one because I can move it around.
