I just picked up a chuck for my lathe and I am wondering if I'd be able to drill my existing bushings with a 60° end mill on my wood lathe.

Obviously the bushings have to be large enough to do this, I won't be doing it on slimline bushings!

Is there any reason I shouldn't do this?

Hi Andrew; I have drilled all of my bushings that didn't come from johnnycnc with a 60° #4 centre drill, held in the headstock with a Beall collet.

Do you have a way to hold your bushings at the headstock?

I can't comment on the use of the end mill!
 
Thanks Mack. My terminology is probably off, I meant a center drill.

I just picked up a Nova chuck and believe (haven't yet tried) this will work for holding the bushings.

I'm curious, when you drill your bushings I assume you put the smaller diameter of the bushing in the chuck? The smaller diameter would be the portion of the bushing that would go into the tube when the blank is turned.
 
As long as the bushing is turned right I chuck on the big Dia. I also make sure the bushing is turing true. Then I drill using a ctr Drill....
 
Only problem might be in the concentric of a Nova chuck, I think they advertise .002 runout, that coupled with the runout on your lathe spindle, you may wind up with some off center or oval turnings. I did mine on a pretty decent metal lathe with a good bison chuck, I grabbed on the big end and I used a # 6 center drill, Maybe over kill, but it's what happened to be in the drill chuck.
 
My chuck at home is not true enough for that... But I do my metal work at work...Have all the good machines there.. Or the CNC stuff.....

Thanks for pointing that out. I'll use my dial indicator to measure the run out of my chuck and lathe to make sure I am not making oval bushings.
