I am in the process of repairing a homemade knee milling machine.
It is about 80% smaller than a sieg X2. Made from castings and fairly tight and rigid.
I am in the process of trying to reduce backlach in the ballscrews ( 3/8 nominal dia with .125" lead).
my question is as follows:
The previuos installation uses two sets of clamped up bearings ( see attached picture) I am wondering if they are sufficient?(The radial play is held by a bronze bushing)
It seems to be rigid enough, but I wont know till it is all re-assembled.
Anyone hazzard an opinion?
