To save everyone from asking or typing a suggestion, yes, a tapered roller bearing would be the best for this build and take the most load. For my purposes, this will be used for small parts and in light pressure setups.

A related question: should ball bearings not be lightly preloaded? I was expecting a screw and washer in the back of the rotating part to squeeze the inner races together.

Joe, One can see why you did as you did. The only question I have is how are the bearings holding up. My live center is very accurate, but not always right for the job. I have a chunk of 17-4 just sitting there and a stack of skate board bearings. Perhaps for occasional use they would work OK.

Given the small size, angular contact would be the cats meow for those looking to overkill the design....but good old conrad bearings are plenty good since they won't see much radial load vs the axial load.

Wouldn't tapered roller bearings call for a tension control adding more delicate mechanics? Thought about head stock tapered bearings...

@@dougberrett8094 As I understand it, plain single row ball bearings are rather sensitive to missalignment of the axle, but can actually take substantial axial loads. Axial load specs are usually 10% - 50% of the radial load rating, deep grove types being best. Using 2 bearings with a spacer works fine for most purposes. As long as You are not making a precision spindle or similar...

Great live center it should last for decades. I made a large live center back in the 70's and it is still working for me.
These "Joe Pie" mini projects are one of a kind. Easy yet useful, simple yet brilliant. We appreciate them Joe!
I worked on CNC for a couple of years in the past, and I have been watching engine lathe machining videos, and frankly I'm amazed at the amount of skills and the quality of the parts machined there.

I can't believe it. I was needing a new life center and now you show us how to build it. At this point I have no excuse. Thanks my dear gentleman and regards from Florence ITALY
Joe, your center needs a bearing for the axial thrust load. The ball bearings you used are only intended for radial loads. An angular contact bearing in the back with a ball bearing in front would work better. A tapered roller bearing could also be used in lieu of an angular contact, or you could add a thrust bearing to the back of your double ball bearing stack-up. In its current configuration, those two bearing will not last very long.

Ball bearings can be used in any light radial / axial application. I think you'll find that most power drills use a couple of ball bearings, adequate for purpose, cheap and plentiful.
@EDesigns_FL

@@TheRunereaper A center is not really a light axial load application; even a small center. This is especially true when the center is used for press turning as Joe demonstrates. If you take a closer examination of the bearings used in drills, when it's just a pair of what looks like conventional ball bearings, you'll likely discover that one of them is a deep grove type, which are designed for axial loads. Also, there is a staggering difference between the axial loads on a hand drill verses a live center. The max load on a drill is ~200 lbs, but you can get more an 1000 lbs on a tailstock.

@@EDesigns_FL With respect, most "conventional" ball brgs are deep-groove. I made an almost identical live centre about 35 years ago and fitted sealed ball brgs (to protect from grinding dust and coolant ingress). I made the ID and OD to fit the most common size of brg. at the time and fitted new ones which lasted for about 20 years on fairly infrequent service. For pressure turning you don't usually need to put half a ton of load on, even though you can. I must admit, I never measured it.
I just discovered a need for one of these for my wood lathe to turn a nylon hammer head. Even held as tight as I can get it with very light cuts the nylon rips out of the four jaw chuck and makes a nasty groove with the tip of my 60degree live center...one of these came to mind as did youtube to see how to make it....well your video was actually suggested in my feed ...very fortunate and your way of doing things earnt you a new subscriber . Your narration and lathe work are exceptional thankyou
I was sitting here going back over some of your older posts and this one caught my eye again. I made one of these a bit biggre using alternator bearings and have 4 different inserts for it. Love it ! It is invaluable when needed. It will stay in it's little wooden box for months and when needed there is just nothing that works so well. Thanks Joe.

Just wanted to say "THANK YOU". I am an absolute novice, hobbyist with a Smithy Midas 1220 that I've had for over 10 years, with VERY little tooling (have to use a hacksaw to part a piece off) and this video made me want make my first attempt at some real precision work. The bearing shaft is a couple of thou too small and the center shell is a couple of thou too big but I am happy with it and best of all, IT WORKS. The whole thing cost me $14 for the cheap bearings at Kaman and about five days working on it during breaks in other projects. I just need to learn what speeds, feeds and bits can give me the best finish. Once again, thank you for putting this out there. Jim in Abilene, TX

I really like this project. One of the few I've seen on the internet that I actually want to build
Thanks for this. Made myself one with 1/2" dia pointed end with MT3 for tailstock. Been needing a little one and this motivated me to do the deed. I chose to have tight slip fit so I can change the tip and not make another MT3 holder. Plan on having conical tip also. Managed to do this and not have runout which is going some for me. (5C collet upgrade helped immensely)
You always have the best small projects to make a novice machinist's life and bank account a little easier. Thank you Joe.

Great video will have to make one of these thanks for the suggestion...
Nice video explaining how to make a very useful tool and from that unlimited attachments to suit your individual needs. Thanks Joe! For those concerned about the axial load there are two steps that can be added. 1) build an inner spacer the exact length as the outer spacer and now the lower bearing will help take about 1/2 of the load where currently is is acting only radially. 2) in addition to the above bore a deeper small inner pocket to exact dimensions for a thrust bearing...which would involve some precise measurements and understanding the bearings and their interaction very well. If you are worried about an axial load perhaps add step 1...Joe was showing us how to come up with a wonderful solution on our own that will work very well for many applications. Thanks again Joe!

Why not use three of the same bearings with no spacers or buy two bearings with side seals and one bearing without side seals and place it between the two bearings with side seals, simple. Equals no spacers to make and it triples the axial load capacity.
@TheGhost1899

@@wwilcox2726 three bearings would work as well...but my thought is that this is a smaller live center for light loads. Also...the further apart the bearings the less radial deflection at the tip of the center. Joe showed us how to achieve that is a very quick and inexpensive way that will work for most applications. If I were to build a little center like this one I perhaps would only have added the center spacer.
Very good design! Thanks for sharing!
