Want to mount a roller bearing in the three point steady rest on a 11"x36" Logan lathe. What width works best for supporting protective collets? Any preferances on brands? There are several supply stores close to the pool room for hands on shopping if I know what to ask for.Thanks for any feedback.

I use a 1.5 inch id bearing for two of my steady rests. I just use cheap, sealed bearings. In this way I can run up to 1 3/8 stock with a collet. I also have a larger bearing mounted in another rest that has a 4-jaw chuck mounted in it. I use it for putting a new center in a pointed cue that's
A-joint is not running dead nuts so as to keep the points even.

I have a single bearing mounted into my steady rest that fits the collet set that Chris sells. I believe it is 1.38 dia. It was a pain to dial in, but once it is, all you have to do is swap collets for the size dowel instead of re-dialing each time you use it. I use it all the time, as my headstock can't fit anything larger than 3/4" so all joint work has to be done outboard with this rest.

I sell the bearing and 10 collets for $95
They handle from .750" up to 1.312"
 
Thanks for the feedback.Want info on the width/thickness not the O.D. or I.D. of the bearing where it supports the collet. I'll use existing collets or build new ones to run in the bearing. I may not have much choice or it may not be important so long as the collet is adequately supported. Seems like it should be at least 0.750" wide. All ideas/experience appreciated.

I am using a standard 6000 series radial bearing. There is also a 6200 series that is a little wider but the 6000 has served me well on three different steady rests. Here is the page the bearing that I use but if you want you can also look at the 6200 also. They only cost a couple of dollars more and are about 4/5 of an inch wide. I use a 35mm id. so that I can make my collets out of 1.5" delrin and have enough material so as to true up the od and still be able to make a collet to a full 1.375 id.

I also use a 35mm inside diameter bearing. The width is not all that important. I think a 1/2" or more would be fine. I also do just like Dick suggested and make my collets out of 1.5 diameter delrin. If you have existing collets then just measure the OD of the collets and go buy a bearing to match them. No use in trying to reinvent the wheel if you already have 9/10 of the work done.
 
Thanks Dick and Chris. Even with 83 belly button birthdays,a University degree in Engineering and 25 years of repairing and restoring billiard cues I am still learning how to tweek a lathe. I have six lathes now so I can dedicate fixed setups...getting lazy I guess. AZ forums and guys like you makes tweeking lessons fun. Thanks again.

The only thing I have to add is about the I.D. of the collets. I have the set that Chris sells, plus sopme I've made since, and their great. I have found though that you should taper the I.D. Otherwise they will do one of 2 things, either leave a dent in the cue were the collet actually contacts the cue, and / or the collet will slide out of the bearing as it's spinning due to centrifugal force combined with the fact only 10-15% of the collet is actually touching the cue at any one time. I also put a layer of painters tape on the cue up against the collet so if it tries to wander, it will hit the tape and stop. I've had collets come totally out of the bearing even though everything was tight as a frogs a$$ when I started. When things are spinning, strange things can happen.
