Hi, Bob.
Sorry it took so long to get back to you. The article is in HSM May/June 2014. Back issues should still be available. Looks like a fairly simple design. It uses Morse Taper extension in the tailstock which you bore out and put in a piece of drill rod. The MT extensions can be bought for $10 or less. The only problem is that it was designed for 3MT and my lathe has a 2MT. I'll give it a try it and see if it has enough "meat" to work. If not I'll go to an outside design that clamps around the tailstock quill. Hope this helps.
