8 mm Shaft Eccentric Sheave And Strap
A print-in-place eccentric sheave and strap that turns 8 mm shaft rotation into a 12 mm push-pull stroke. Use it to drive pumps, shaker tables, sieves or agitators. The 44 mm disc has an 8.3 mm bore set 6 mm off-centre, locked by an M3 heat-set set screw. It turns inside a captive 56 mm strap ring held by a 45° V-groove and bead. The strap's arm ends in an M4 clearance eye at 80 mm centres.
8 mm Pin Rip Fence Cam Lock Lever
A replacement eccentric cam lever for benchtop table saw rip fences and other cam clamps. It pivots on an 8 mm steel pin or bolt (8.3 mm slip bore) and its spiral lobe rises 4.5 mm, from 13 to 17.5 mm radius, ending in a flat locking dwell. The lever is 117 mm long with a 12 mm thick cam, so you can swap it in for a broken OEM lever without buying a whole new fence.
Eccentric Input Cam
This is the input eccentric for the 'NEMA17 Cycloidal Joint Actuator' kit. It clamps onto a NEMA 17's 5 mm shaft through a Ø5.2 bore, using an M3 set screw that threads into a captured M3 hex nut. Its Ø24 lobe sits 1.5 mm off-centre and drives the 15-lobe disc. The part is 30 mm across and 10.5 mm tall, and the Ø30 thrust collar holds the disc up.
