Hi Bob, et-al;
A question about parts 15 (3) and 17 (1). These are the bearing trucks for the Y/Z carriage. All of these parts have a .3125 (5/16) through-hole to carry a 5/16" socket head cap screw for the bearing axle. They also have holes for set screw adjusters.
I am guessing that the through-hole should be 3/8" (0.375) to allow for adjustment instead of the .3125" show on the plans? I should have asked before I put it together, but better late than never.
On a different note, mine lives! I still need to finish the Z axis slider and to the final alignment, but it works. Pictures to follow.
