Hi Malc, Yes, I have done my ML10 using the bearings supplied by ArC.
The main problem is that you have to machine the end plate of the top slide and if its the lathe that you are doing then you have no top slide to work with.
How I got round this was to swop the end cap off my Vertical slide and do that one and then just do the swop onto the lathe when complete.
It does work very well but be careful not to tighten the spindle too much when adjusting.
It does smooth out the movement and I am pleased with the result.
