As you may know, the tool post on the G0766 lathe sits a little too high for some operations. In its lowest position, it is perhaps 3/8 to 1/2 inch below center. I found that with my favorite 3/4 inch bowl gouge that it was hard to cut off the nib in the center of a bowl without raising the tool handle to an awkward height.
I've read and heard that Grizzly is in the process of fixing this, but I have not yet received either the replacement part or word of when it is coming. I was growing tired of having to work around this problem, So I decided to turn off the shoulder of the tool post. I tried a number of different approaches and the one that worked best with what I have on hand was to turn off the shoulder using my new Grizzly lathe.
For the cutter, I used a 1/4 inch cemented carbide metal lathe bit stuck in the end of a 2 foot long 1/2 x 1/2 square bar and a vice grip for stability. Oh, and I also used an old tool post for my Craftsman 9 inch lathe along with an adapter to fit the Grizzly. I used a collar with a set screw to control the depth of cut (very important) and probably only took off 0.020 DOC per pass. When I was ready to make the next cut, I loosened the banjo and tapped it slightly with a rubber hammer. I had to shim one of the jaws of my new Grizzly chuck to eliminate runout. It was slow (probably took me an hour and a half) but I got pretty good results. I am attaching some pictures (one is a work-in-process and the otherone is the finished shaft) for those who may be interested.IMG_0026 (1024x768).jpgIMG_0023 (1024x768).jpg
