Once this idea hit me, I just had to build it…couldn’t devote my mind to anything else. Fun build and I believe it will be the last of this type. RINGMASTER ADAPTION DEVICE NO.3. I kinda like this one, easy to build and works well, once you get use to it. All things have a learning curve. Hope someone can use this idea, Easy to build if you already own one of those cross slide drill press vises. Only trouble is one needs a large swing lathe. These vises have movement in two directions, one advantage of the vertical slide is you can adjust the height of the cutting tool. Just made to order…

Only wood part one needs to construct out of wood is the tool bit holder, One piece of a hard wood, a lip cut to fit under the jaws of the vise for extra strength, clearance for the disc to be cut and a slot for the tool bit.Almost done before you get started.

That was easy eh! This time I made my own cutters, recommended, Used 1/4 HHS bit. To start the shape, clamp it in a vise, heat can dissipate into the vise, I used a thin cut wheel on the angle grinder, but the whole job could be done on just a grinder.

A couple tips on finish grinding, parallel or slightly winder at the tip, taper the bottom slightly to the cutting edge, and relieve the sides slightly to the bottom, better clearance for cutting.

Then just add some plates to secure the cutters in the slots. Thumbnail pictures. Oh yes, mounting the vise to the lathe. just a steel plate to bolt the vise to it, a stub shaft to fit into the tool holder, one bracket welded to the post and plate, a ubolt at the bottom is very important. Assemble so cutters will be near center and take the whole assemble to the welder.

That wasn’t that hard… I also made an improved drive system for the lathe, end grain oak screwed to a faceplate. Good and solid, works well.

No matter how you construct a ring cutting device for your lathe, some of these ideas may be helpfull, 1/4 lathe bit stock, is better when you are working with wood holders. Maybe you may come up with a better idea. I have had allot of fun designing these devices. Of course they will not work as well as the real thing, but I have enjoyed making simular projects as done on the ring master lathe. in the video I explain some of these things I described and you get to see it in action. The bowl is from my first attempt. It was I thought a scrap piece but turned out to have some great patterns in it. A keeper. If I actually tried to get a nice piece of wood I may come up with something to write home about.

By now you may think I am crazy, just turned 70 so I have an excuse. Thanks for looking, comments and suggestions are appreciated.

Great idea and implementation, Brian.
Thanks for sharing this.


-- Bob, Western Australia, The Sun came up this morning, what a great start to the day. Now it's up to me to make it even better. I've cut this piece of wood 4 times and it's still too damn short.

I know that it’s Roche de Bule that causes this madness! Keep looking at it because your ideas are refreshing!
Have been looking at a few blanks from your wood. Some interesting stuff coming up! Will post when ready! Roman
