I am tossing the idea of taking our 2015 and make it capable of broaching internal keyways. I can orient the spindle, but obviously theres way too much play. I have heard of people locking their spindles, but how?
I want to be able to orient the spindle, as I want to be capable of orienting off a feature or doing multiple keyways accurately.
Since I made a spider for the rear of the spindle, I was thinking of making a sort of adjusting cradle to be mounted below the chuck, near the bed. Once you orient, you can screw the cradle up tight against the chuck. It would be out of the way and it wouldn't interfere with regular running. Only thing I would question is the upward pressure. Granted it would probably take a lot of pressure to move the chuck/adapter plate out of alignment, but i'd feel better clamping from both sides.
Material to be broached will mainly be 1018 and 1045. Stainless would be done elsewhere. Keyways from 1/4"-1/2". From 1" to 4" deep
thanks,
Josh
