A friend asked me to drill a hole in the center of about 30 stainless steel caps.

Bored the soft jaws to the needed diameter with a should to hold them with the face perpendicular and we knocked them off in no time.

Steve, thanks for posting this write up. Many people have commented on soft jaws but I’ve never seen an actual description and photos of parts made with them that made sense. The workholding really points out how to make these things work and how they can be used.

Very beneficial.

I found a 40" length of aluminum bar just waiting to be useful...

I'll de-bur them as I use them.

That should do it for soft jaws for quite a while, and the CNC mill is quite happy.

Operating machines is perfectly safe......until you forget how dangerous it really is!

2" bushings needed shortening as well as ID and OD changed.

Needed .002" off of the OD, so the soft jaws were pre-loaded and cut to accept the bushing flange. The bushings then ran dead concentric to the spindle axis, so shaving .002" from the OD was easy.

Now the ID gets sized.
