Just thought to post a few pictures of this steady rest I fabricated for my ML10. Lots of fun to make and rather instructive for me at that.
The clamping base is made of 6mm hot rolled strip stock, the vertical portion and moveable arms from 5mm hot rolled and the guides from sections of leftover square rod.
The construction is stitched together with TIG welding and then milled where required… and vice versa. Those are cast-off bearings purchased from the flea market… the only thing not visible being some tiny brass tubes I turned to reduce the 7mm bores of the bearings down to 6mm to match the bolts.
It seems to serve well enough so far. I'm planning to extend the width of the support arms on the ends opposite the bearings and then add on a 'pad' of silicon bronze for use on parts that might be a tad soft and thus too sensitive for the hardened outer race of the bearings.
