GadgetBuilder's MiniLathe and Little Workshop
Unfortunately this collet was not drilled accurately so it is useless due to excessive runout Ball bearings were added to the mini-lathe controls beginning with the cross slide followed by the compound (much easier to do than the cross slide) These ball bearings transform the feel of the lathe and are WELL worth adding
My DIY mini
Why two spaced angular contacts over a double row angular contact in the front and a spherical on the back (typical of modern machine tools) or tapered roller bearings on each side (typical of mini lathes)? I think run out and carriage axis misalignment and hysterisis errors

Odd runout on mini lathe
Mar 19 2019He's getting (or was getting before the bearing fell apart) 0005 runout on the inside of the spindle taper While not exactly stellar I suspect that's the best he can hope for with that machine Seems unlikely that the taper would be bored cockeyed and yet that close to concentric at the big end

Headstock upgrade
A pair of 30206 taper roller bearings was ordered on ebay Recently Real Bull a Chinese company that manufactures a minilathe clone has introduced a new minilathe with a 100 mm spindle flange This new development enables a 100 mm chuck to be directly attached to the spindle thereby saving the space occupied by and the inaccuracies inherent

Tapered roller bearing runout on mini lathe
May 19 2015I know replacing the stock bearings in the mini lathe with tapered roller bearings is a popular upgrade and one I'm looking at right now However my research shows that the commonly available 30206 tapered roller bearing is the basic grade K which has a total indicated runout of 0 0007 or over twice that of basic ABEC-1 ball bearings I just wanted to see how people are
A bearing question
One could throw together a 2 500 RPM mini-lathe spindle with off-the-shelf $10 automotive bearings and have a pretty decent setup good to probably even a little under 001 TIR with a little care If you need a 10K RPM spindle with a runout down into the millionths it's gonna cost a LOT more
Mini lathe cut off incident : Machinists
So I was cutting off some aluminum on my mini lathe and the piece rode up on the cutting tool It jammed everything up pretty good but it seems to be working fine If you haven't already put tapered roller bearings in the headstock now might be the time to!

Taper Roller Bearing Preloading
Mar 21 2010Taper roller bearings are significantly stiffer then angular contacts but have noticably higher friction/drag of the same size Taper rollers are less able to accommodate angular mis-alignment than angular contact bearings Taper roller bearings are less accurate than an equivalent spec angular contact bearing - This does not mean that all AC
