Dave asked if I did Corian rings and so I did three black corian rings in 3 different sizes. I also turned 3 pendants in CMU ( Central Michigan) colors. I was cutting some purple heart and Osage orange and I dumped the chips together and they looked so close to the CMU colors that I had to laminate the two woods together and these pendants came out of it. All these pieces are finished with EEE and Shellawax.

I was asked to show the expanding mandrels I use to make rings so I have a series of process shots of how I made the corian rings:
If I start with flat stock, I drill holes so they can be mounted on a bolt and rounded up on the metal lathe or the wood lathe. I use the metal lathe for these.


I turned them round to a little over the finished size.


Then I bore them to the ring size.

These are the 7 mandrels and the 3/4”nylon adapter that fits the wood lathe chuck


Then I mount the ring on the mandrel and expand it by tightening the screw. If the ring is weak, it usually breaks at this stage.

Then I turn and finish the ring -flipping is from side to side in the process

Here are some close up shots of the mandrel and the adapter

Real nice Jim. The Corian is a good material to work with.
Thanks for sharing.

Bob.

Well done Jim. I agree with Ivan you have the accessories to do a lot of different things easier. I for one find it so much harder to turn anything small as compared to the larger turnings. I have to be careful. Those black rings are cool. You could sell them as Black Friday specials. Did you ever try that plastic finish they have for pens I believe, as compared to the Shellawax?

Thank you all for the nice comments.

Hi Joe. I had the elves on overtime yesterday. I skipped school and spent 12 hrs in the shop!!

Hi Mark, Yes, I made the mandrels too. While that nylon adapter was turned pretty true, the combination of it and the wood lathe chuck does have a little runout when sticking the mandrel in it. I just discovered that Pennstate sells a PSI collet chucking system with 5 good steel collets ( 1/4”- 3/4”) that go in a holder that fits right on the spindle- that should make it run “right on”. That will be my Christmas present to me!!Ordering it today!! Dave, you might want to look at one of these chuck systems for small stuff. There is no other good way to hold it and a lot of time I can’t be between centers.

Hi Kelly.I hope you have a Merry Christmas and Happy Woodworking New Year!!

Hi Dave. I have never tried the plastic finish. I have used Mylands friction polish and clear lacquer.

Cheers, Jim

Hi Bambi. There a other ways to make rings, but I went this way because I can get at both sides for cutting, sanding and finishing. My first mandrels were made out of hardwood with a wood screw in the center but they did not have much range before they cracked apart. These nylon ones have about .030” range, so I needed a bunch of them for all sizes.

Jim. I have had my eye on that collect system for a while now. It seems to be a decent set. Good idea, Christmas present. Maybe I can get someone to get it for me. I’ll add it on my list.

thanks Lee.

Hi Dave. I ordered it from the catalog that says free shipping on anything over $59 and the lady said certain things like it and Shellawax still had the$10 UPS charge. I order 5 things and she took off the shipping!! I have looked at others like Beall and they want $159. Some other brands were more yet! I read the reviews and all were 5 stars except one guy that has 1 1/4” lathe spindle and he complained because a long part would not fit because it is a 1”-8 thread and he had to use an adapter. I’m going to drill my adapter out with a 1/2” drill- problem solved!! I’ll do a review on it when it comes!!

cheers, Jim
