Mounting screws
The countersink of the hinge's holes is meant to be used from the other direction, so screws may stick out a little
It's a good idea to drill this hole after everything is put together to position it so that the idler assembly sits exactly level when the jig is in normal use.
2-2.5" (5-6 cm) wide hinge
Smali washer - as smali as you can get to still fit on the #12 screw
- 7/8" outer diameter bali bearing. Same bearing as used on end of threaded rod
#12 countersink wood screw, the shortest you can get.
