Here is another form I did recently. High mountain oak from the Santa Rita Mountains in Southern Arizona.

Bill, tell me more about how I can refine this any more than it has been. I’m using 4140 chrome moly steel for all the parts that make up this tool. The live center shell is heat treated. The threads are 16 tpi. There is approximately 3” adjustment from nose to wood, and 3 5/8” between wheels when fully extended, or 2” when reversed and retracted. There are 3 bearings, one 32mm thrust and 2 axial bearings at 32 and 35mm OD spaced at 1.700”. I think it’s up there in tolerence @ + -.001” at the most…. The pictures you’ve seen so far is of the first one I made and have used for the last year.
I’m about 1 week away from completing 14 new ones with revisions from the one you’ve seen. Now I need to find a machine shop that can make them here in the US for a price that woodturners can afford…
I’ve also posted a video on youtube, http://youtu.be/cCW4mCNdR8I . It started out as a 3 part video, but the first video wasn’t pertinent to what the second shows. Even this one doesn’t make much sense until I bring up the wheels and remove the tenon I created, then made another and removed it also. It’s not buffering properly on my computer, so I hope you have better luck with it than I do….......
It took over an hour to post a 9+ minute video, so next week I’ll post more that are a whole lot better.
For those of you that might have an interest in flintknapping, check out 2 other videos by me entitled, Jerry’s Blades by Nubsnstubs. ........... Jerry (in Tucson)
