Pennington Single Slide
Dan emailed me about this new idea. Here is our conversation (edited):

A little update on my rim lathe.
I changed from two Enco cross slide tables to one Palmgren table. I use the boring bar for both inside and ouiside of the rim cutting.
I couldn't adjust all the slop out of the Enco tables and still have them slide freely. The Palmgren is a lot better made and a lot more expensive, but worth the cost for the accuracy and smoothness of action. With the Encos I was getting grooves around the rim which were hard to sand out.
My next move will be to build a new lathe head like yours with a couple of pillow blocks, a shaft, and multiple pulleys driven by an electric motor. And get rid of the Sears lathe before it dies.

Great to hear from you. I love the simplicity. I get very rough cuts from my boring bar. Maybe because of the Enco slides. I have long wondered about the Palmgren slides because they look a lot like the Enco slides. Same factory working to different specs?

I was getting roughness at end grain and chip out at the block joints because of the short end grain primarily with maple. Softer woods seem to cut better. I don't know yet if the Palmgren will do anything about that. I installed it this week end and haven't cut an inside yet. The outside cut is very smooth.
