I recently got back into woodturning, after nearly 10 years off to pursue graduate education. Found a 2436 on Craigslist and boom, back into turning. The lathe came with tons of extras including 2 hollowing rigs. One of them seems to be made by Frank Sudol... a large rig made of mostly 1.25” solid steel bar 6’ in length. It also included 2 cutting tools(5/8” OD) that fit this bar and 3 that are larger (3/4”OD) The roller it came with is also pretty heavy duty but the one thing that worries me a bit is that it’s not a CAPTIVE roller. The bar just rests on top of the roller. I’ve searched the Internet pretty deep and can’t find a ton of info on the systems Frank used to use (and I believe sell). Does anyone know anything about this system? Should I modify the roller or buy a new one to make it a captive system or do you think it’s heavy enough (mostly solid bar stock) to use safely without going too deep? Is there another bar that takes the 3/4” tooling that Frank also used/sold? More curious about the system than anything else. Need to get more comfortable with the Jamieson system it came with before I try anything bigger. Thanks!
