I just gave up for the day on a machining project, first time this has happened in years.
I'm trying to use my Bridgeport slotter to cut a 3/32 keyway in a 3/8 shaft. I keep advancing the tool and not cutting metal.
All slotters and shapers have a clapper that lets the tool give way on the return stroke. After quite a while, I determined the clapper is giving back and not snapping back forward on the cut stroke. I've tried tightening and loosening, no joy. The spring on the clapper is not very strong, you can move it back with your finger out. Should it be far stronger?
Or maybe I don't have enough relief and rake angle. What's right here? I'd pull my hair out over this, but I'm already bald.
I should say, I use this tool about once every five years. So, I'm not very proficient. I may give up and buy a 3/32 broach. But, I think a broach may not work either as the keyway is 1.5" long, or too long to broach easily.
