I was working on my HW97 the other day installing buttons on the compression tube and piston and discovered I needed buttons. My new 6 jaw chuck was mounted so I got out a 1/4" stick of Delrin and proceeded to mount it in my new chuck and discovered that 1/4" was too small for the chuck to hold. What to do? unmount the 6 jaw and mount my 3 jaw... mount my set-true collet chuck and install a 1/4" 5C collet?
I'm too lazy to change chucks all day (old guys work smarter not harder), most of this day's work was going to be accomplished with the 6 jaw chuck.
I routinely use a 1/4", 5/8", or 3/4" drill chucks for very small work mounted in my 3 jaw or 6 jaw 6" D1-4 lathe chucks. I use the TORMACH Tooling System, a system of low cost tool holders designed to provide easy tool change in my mill fitted with an R8 3/4" precision collet.
I got out a 1/4" 5C collet and took a look at my 6 jaw chuck... the jaws closed on the 5C collet without touching the threads on the collet body... problem solved. Mounted the 5C collet in my 6 jaw chuck, installed the 1/4" Delrin rod thru the spindle bore and cut out about 100 buttons but next time I'll just get out my 3 jaw chuck mounted on a 5C collet and mount it in my new 6 jaw chuck; the little 3 jaw chuck can hold anything the drill chucks held too... there's no end to the easier (smarter) way of doing things.
Back to work on the HW97.
