Oh man, I didn't even think about that.? That's a good idea if this carriage bolt doesn't work.? I'll keep it simple for now with a carriage bolt.? I might have a t nut laying around for the x-y table on my drill press.
Thanks animal,
Jody

Animal,?
It is similar to a carriage bolt.? The square portion at the head fits into the banjo slot and keeps the bolt from rotating.? The flange of the bold keeps it from sliding thru the slot of the banjo.?

In your plan what keeps the bolt from sliding out of the banjo.

My feed rate gearing is set at 0.0035" and I comfirmed that last night.? I was turning some stainless with a carbide index cutter and the finish was awful.? As a novice I'm still learning my metals and cutting rates, so it is an experiment half them time.? But I'm learning to pay attention to the cutting rate tables.? Anywhoo.

I wanted to reduce the feed to the slowest rate (Is it 0.00187?) and pulled out the MOLO and looked at the gear chart.? This would've been the first time I've changed gears since getting the rebuild done last year or so.? The figure of the gear arrangement showed 3 gears on the banjo.? Well I only have 2 bolts to hold the gear on.

I put the gears back in the position they were in when I first got the lathe from my dad, so never noticed I'm missing a gear bolt till last night.

The gear bolts have a thicker head on them versus a carriage bolt, will I be OK using a carriage bolt??
I don't see why not since there isn't tension on the fastener.

Just want to see if you guys thought that was OK.? I don't even know if you can find a bolt like the one on the lathe.
Thanks,
Jody
