This is my homemade hollowing rig. The shaft is 1/2" square steel, the outrigger is 1/2" steel also. The tip is a 3/16 tool steel cutter and the scraper is a section of grade 8 bolt. The high strength bolts make pretty good cutters. The handle is oak, 24” long, drilled in from the back end approximately 6” and filled with lead shot.
The laser mount needs to be out of heavier stock as the vibration from cutting makes it jiggle a little.
The rig works pretty well as long as I don’t get too far over the rest as the vibrations get your attention.
I think that I will probably re-build with a 5/8” or 3/4" round stock for the shaft. That should help reduce the vibration when reaching farther over the shaft. I may eventually make a capture rig for the back end.
I have posted some of the hollow forms that I have done with this rig in a post on lathe projects.
Anyway, comments are welcome.
