Chinese Lathe directional control eccentric brackets

thingiverse

These parts will fit many many Chinese lathe clones on the market in the 9, 10 and 12 inch range. These two eccentric cams are located on the spindle direction rod. Their purpose is to activate the two interlocked micro-switches that control the forward and reverse motor direction. The original parts are prone to cracking and loosening throwing the orientation out of whack and causing the motor to fail to be activated. I machined new parts out of steel because at the time I lacked a 3D printer. You can print these out of pretty much any filament. Use 4 walls or more, slow print speed and get a great PLA part. To make the part more durable drill out the modeled M6 thread and heat stake in a short M6-1 heat set insert like the manufacturer should have.
