Re: Dismounting the headstock bearings
Gotcha. If it was me, I'd start with two things. First would be pulling the headstock apart and addressing the bearing adjustment problem. The inner race on the outer bearing needs to be able to slide

Re: Dismounting the headstock bearings
Ryan, I'm not speaking of alignment accuracy that would mainly lead to a machine a taper instead of a cylinder but of runout of the chuck that is currently resulting in an irregular

Re: ANSWER TO GUIDE RULE - OT
Not bothered about having flat spaces next to the tools, that’s what benches are for. They’ll be roughly the same height as my current benches so it’ll work out. There might be some depending

Re: cutting with rotating cutter
Thanks Roy I am cutting clock wheels for my private clocks. Even though the Carriger has a very tight fit when I cut wheels, I feel there are a little bit twist when I return the cutter for next

Re: cutting with rotating cutter
Yes! Either method works, The carriage wheel gives more rapid carriage movement, a leadscrew crank gives more precise movement. Adding a leadscrew crank is pretty easy & gives you the option of

Re: Dismounting the headstock bearings
1/100mm is about .0003". Over what distance are you trying to maintain that? Just curious as it shouldn't be a problem on shorter lengths with everything properly adjusted and aligned especially the

cutting with rotating cutter
Question: Is lead screw a better tool to move the carriage correct in both direction than use the hand feed wheel? If so, I will make a crank on the right side of the leadscrew. (I am lazy, I do not

Re: Dismounting the headstock bearings
Hi Jon, Thank you for your reply. For your information, my lathe chuck is a 100mm (4"). As far as I know the bearings are of the tapered type but I didn't verify, just

Re: Dismounting the headstock bearings
Ryan, I agree with you and I'd like to add some comments. Concerning the use of tapered bearings, my lathe came with them and I didn't touch them until I decided to get rid off a

Re: Dismounting the headstock bearings
No, tapered bearings aren't sealed, see my other post, you'll see that I'm wondering how to ensure their maintenance. The gear side might be accessible for oiling when the nuts, the pulley

Re: Dismounting the headstock bearings
You're correct but the lathe was delivered with such bearings.

Re: Dismounting the headstock bearings
Roy, I already have tapered bearings but my problem is that they are mounted tight and I can't manage to reduce the clearance between them.

Re: Dismounting the headstock bearings
Hi John. Yep, my lathe is a two speed one and I have the LMS metal gears in it. To me the gears are pretty quiet. If I grab the chuck and rock it back and forth there's some gear clunk naturally but

Re: Dismounting the headstock bearings
Thanks Ryan for your experience and results report Is your lathe a 2-Speed and are you running metal 2-speed gears as well? How is the gear meshing noise? TKS, John

Re: Dismounting the headstock bearings
My tapered rollers have been in for 10 years. I haven't touched them in 3 1/2 years since I installed my els. I pulled the rear when I had the nuts off to install some parts for that and in the prior

Re: Dismounting the headstock bearings
I am on the fence about ACR vs TR, Did you get rubber seals on your bearings? Do you oil them regularly? Maybe 1 drop before each use? Does oil leak out the bottom of the bearing or middle of the

Re: Dismounting the headstock bearings
I believe the OP has tried to install tapered roller bearings and can not get the preload just right.? I could be wrong tho, even very wrong is possible.....

Re: Dismounting the headstock bearings
What this whole thread is overlooking is the fact that the OEM bearings are deep groove ball bearings; the cheapest option! An upgrade to angular contact bearings gives more thrust resistance to the

Re: ANSWER TO GUIDE RULE - OT
You have to consider that the Craftsmen "rotary triple" gizmo for three tools also provides a little flat workbench space on each side of the tool.? That is probably useful.? It is true that you
