Yes, I used some 12.25 mm dural plate I found cheap on Ebay. Wanted to make sure nothing would flex.
The big pulley on the nut, why is there no edge ? It would stop the belt from sliping. But should OK I guess.... :-)
Some of the pulleys I've seen with flanges have steel ones pressed on which would have made the machining difficult. I machined the pulley with a recess each side to locate the ballnut and the bearing and keep everything lined up. The pulley on the motor is one I rescued from a dead belt sander and has flanges both sides so that should keep the belt in place, if not I can always make a flange for the big pulley.
Now, when are you making the first swart ? :D
I hope I don't make any SWART :-) but I've given up predicting when things will be finished!
