I was getting a little frustrated since I couldn't find an XL belt that was long enough for my z-lift.
I went into my parts box to see what kind of Nema 17 motors I had. I have some with 5mm shafts.
I went to McMaster and boo hoo, I didn't see any metric.
But when I went to sdp-si, yippie! They had lots. And belts as long as 7m!
Q1) If I go metric which pitch should I use?
Q2) Is it a common practice to drill pulleys? For example if I got some with 6mm bore for my z-lift, I could drill them to 1/4" so they will fit on my 1/4-20 shaft? Is that a good idea?
