The female is a simple part. Replace them both with a common spline size.

Anybody see "ALIENS"? They're making 6 ft vertical welds on some sort of space ship alloy using a cordless welder about the size of battery operated drill.

Thanks!

I'm trying to PM earlgo but the messages won't show up in my "SENT" list. I was browsing around in the PRIVATE MESSAGE section and found 2 of the PM's I sent in the "OUTBOX". What's the difference between "SENT" and "OUTBOX"?

The way this is described tapping the shaft in or using a sliding hammer to pull it out will apply the force to the inner ra...

To turn 60tpi into 30 tpi you have to double the speed of the leadscrew.

First you have to check the alignment of the headstock to the bed independent of the tailstock. This can be done with a ground rod in a collet or a test bar. I use an MT5 test bar the plugs right into the spindle bore with no other attachments or parts to degrade accuracy. Best $100.oo I ever spent....
