Hey, thanks, Glenn. I've been thinking about this upgrade.

Hello Slinger, I've been thinking about it for a couple of years. But now that I plan on doing a larger motor upgrade, I felt I had to do it. Hey, thanks for watching.

Great video Glenn, thanks for sharing 👍 Definitely need to do this mod to my mini lathe at some point!

If you're going to use your lathe alot you most likely should change out the spindle bearings. Thanks for stopping by.

Tapered bearing are far better than regular bearings in many ways , most of all side load when facing and parting ! My lathe has a 2 HP motor and when I got it I had no problems parting .. now I at times do .. and I am going for the taper bearing swap to get better preload and better side load .. I have done a bunch of study on this .. folks want to argue on this but there wrong !! great swap ..

Everything you said is true 👍 about tapered roller bearings. That is what they were designed for. Thanks for watching and commenting, have a great day 😀.

I ran my steel gears through a tumbler with stainless steel tumbling media to polish them and knock off the rough edges on them. That helped to quiet them down.

That was a great idea. I have a small tumbler, I should have done that also. Thanks for watching and thanks for the comment.

The one we've been waiting for! Outstanding job sir, that was a lot more work than a simple bearing swap - kudos for going the technically more complex taper bearing route 🙏

Thank you for the kind words. We will see if they are any better or worse than angular contact bearings. These were definitely a lot cheaper. I feel that I needed the steel gears with me working on putting a much larger motor on the lathe. But, It was all fun to do. Thanks for watching and leaving a comment.

Great Job! Bearing preload is always tricky.

Thank You, Bearing preload not only tricky but important also. I will probably have to check the preload occasionally, I'm sure as the bearings wear in the preload will change. It was a fun project, Thanks for watching and commenting.

Thanks for the video. I am on my 4th or 5th set of tapered roller bearings in mine. I seem to be tightening them too much but am not sure. They make noise as soon as I put them in. I wish I would have seen this video before the last time I took my lathe apart. I could have made those .050" shims. I also need to cut down the outer spacer. ...I guess.

It seems to me that if you don't have the proper shims and spacers in the right places you could very easily mess up your new bearings. Thats why I went through the trouble of measuring and drawing everything out on paper. It seemed to be easier to understand. And then setting the preload. But thats just me.

usually you dribble some gear oil over the steel gears

Oil or grease, it's all good 👍

Did the new bearings improve the runout of the spindle?

Yes, it did improve the runout. It also helped to get better finishes on the work piece.

I'm new to all of this and pretty much been running at high gear. What is the advantage to running it in low gear?

@GlennNowOnYouTube

A real simple answer would be something like, If you're cutting hard materials you would go with low gear. Softer materials would be high gear. That would be just the beginning when talking gears. Be careful and enjoy your lathe. Thanks for watching.
