Wrong thread George you want The "hope it'll cut Ali" one

Back to the bearings I have found an excellent company called Bardens and the catalog is full of bearing usage and design guides but in nice easy to understand format. The big upside is that they have a UK branch just down the road from me, but I expect they will be mega bucks and wont deal direct with a small time hobbyist. Still nothing ventured nothing gained.

Heres the catalog if any ones interested http://www.bardenbearings.co.uk/c2/u...20uk%20cat.pdf

Theres also some precision bulletins that deal with effects of high speed and using smaller lower mass balls to counter effects, scroll down the page a bit.

So maybe I can build just one spindle after all
