STUBBY CHUCK

[epanzella]

A pending shoulder surgery has limited my ability to lift my right arm and made drawbar activities nearly impossible on my mill. I had an old drill chuck with R8 shank kicking around that I hadn't used in years. I turned down the R8 to a stubby 3/4 inch straight shaft so I could stick it in an ER32 collet. This has saved me a ton of tool change time when drilling/tapping, ect.

I use chucks with both 1/2 and 3/8 arbors. Saves a lot of time over having to change out a R8 arbors.

I have been advocating stubby arbors for a long time, something I learned from Fred. So much less cranking of the knee.

I'm mostly using R8 toolholders so any project with a lot of tool changed is a good-news-bad-news situation. The bad news is lots of knee cranking. The good news is that I don't have an MT4 spindle because that's even longer than R8.

The bad news is lots of knee cranking.

The good news is how nice it gets when you put the knee power feed on. Really like mine, worth it.

What are you using with these chucks? I would be ascared to use and end mill? Especially slippery carbide. Or do you use your mill for drilling a lot?

I never use an end mill with the stubby chuck. I just pull it out and use the ER32 for end mills. The stubby chuck is for mostly for drilling/tapping.

I guess I lucked out. My Tree mill will only accept "Z" collets. The largest is 3/4 so I have always had stubby 3/4" arbors on everything.
