Logan 200 Saddle/cross Feed Screw Question...and Some Others

Hmmm ... I have thrust bearing (ball type) that I was going to put on mine as part of my larger dial project (which has been half completed for way too long).
 
It might work for you? The roller bearing I used was this one: http://www.ebay.com/itm/360392191644?_trksid=p2057872.m2749.l2649&ssPageName=STRK:MEBIDX:IT which was cheap. But may have been the way I put it in. The oilite bearing worked great. There is however a minor gap as it was only 3/4". Later on I should probably search out a larger diameter to turn down. But for now it works great.

I do want to do the larger dial project myself. But I have several projects that have been going on years. (One is over 10 years now and taking up several feet of work bench.. oops.) So I know exactly what you mean Mister Ed! Does your user name reference the show? I used to watch that.
 
We'll see what happens. The dial I have had about 75% completed for 2 years uses a needle thrust bearing and a ball thrust bearing.
Here is the old thread, albeit without much content:

My plan was to put the needle bearing between the two main pieces that I made. That would take up the slop on the user side of the cross slide. I was planning on maybe putting a ball thrust bearing on the internal side of the screw (between the gear and cross slide casting) to take out the slop in the other direction.

Maybe I need to work on that this spring!! I think it is complete, except for the index able collar.

Looks interesting. I'm confused as to where by the pictures you would put the ball thrust bearing. Probably the surfaces you would have would be a lot cleaner than the ones I have on the existing parts allowing for less binding possibilities. After I use mine a bit I'll have to take it apart and inspect the oilite bearing to see if it's wearing anywhere.
