I'm wondering if exist a way to build in a simple way the equivalent of a flanged mounting block for the fixed end of a ball screw.
Unfortunately cheap commercial models are for 10mm shaft, ergo 7200 ball bearings, while a need a support with 12mm bore diameter, so 7201 ball bearings.
These items are quite expensive for low budget projects and i'm considering to try to build a couple for X and Z axis of my DIY XYZ pantograph.
Of course i do not pretend same strenght and precision of metal ones, but something that would be OK for a wood machining CNC device.
The first problem is :
i do not own a lathe ...
but maybe with a quality forstner bit, some delrin slices, a couple of 7201 bearings and a collar ....
Has someone managed to get something similar to work good ?
Marco.
