Everyone's posting their Home Made Hollowing Systems so here's mine. I finished my system last week and have not done a lot of hollowing with it but it does seems to work very well.
The Hollowing System is based on the Lyle Jamieson System.
The boring bar is a metal turning boring bar purchased from eBay, it is 3/4 " and uses 1/4" metal turning bits. The bit is positioned at 45 degrees on one end (as shown in the photos) and 90 degrees on the other end. With this boring bar I can hollow approximately 10" deep. The Jamieson 3/4" boring bar with bits will work with my system so if I wish to hollow deeper than 10" I can use the Jamieson boring bar.
The laser is a laser pointer from Staples ($20).
My estimated cost is $50 to $60 for the complete system.
Thanks for looking, comments welcomed.
