Alisam spring loaded index pin.
john Lucas
I forgot who posted this idea on the springy index pin for the Alisam. What a fabulous idea. Whoever posted this get back with me because I want to give credit. I did modify it a little. I put slot in the bottom piece because I want to be able to use it on my midi lathe as well. I will make another spring for the midi and another bottom locking piece.
I did put screw threads on the bottom of the spring arm and fastened in place with a thumb screw on top and set screw to lock it in position. The idea is to be able to really fine tune the position of the wheel when I need to pull the turning off and reinstall it. This way I can lock the spring in the wheel, loosen the set screw and rotate the thumbwheel up or down and then lock it in position. My slot wasn't quite long enough for both lathes so I bent the arm out a little and that took care of the problem.
The extra hole in the side of the bottom piece is simply because this was a scrap piece of aluminum that already had that hole.
I'm going to make another spring to fit my IronfireLLC wheel so I can use either one with this system.
