Pros and ckns of round bar tool rests
John C Lucas
First the pros. You can rotate them around. My favorite is a 9" round that has an off center tool post. Great fkr bowls. I can rotate it one way so the long end stocks inside the bowl deeper or i can flip it around to use the short side when that works best. My curved rest is similar. I can use the same rest inside or outside a bowl by simply rotating it. I have one that has the tool post off center. Again you can rotate it eather way. This can halp you get the banjo out of the way for certain cuts or projects.
Cons. The tool rest that omes with many lathes are designed to stick out far enough that the front edge is in the same location as the banjo. So when turning a platter you can ha e this edge very close to the wood. On 3/4" round bars on my Powermatic you need the rest almost an inch away. Not so much of a problem on my midi lathe because the banjo is thinner. I have a Robust thin or mini tool rest with a 1" tool post that is my favorite rest because i can reach my fingers around it to support thin turnings. However i cant put it close to platters.for the same reason. The full size Robust rests stick forward faf enough this isnt much of a problem.
I like to use a pull cut with the handle very low. Thks can be a problem on my factory rests because tilted angle is not great enough. On round bar rests as you lower the handle your moving the fulcrum point to the side of the bar away from the wood which means the supporting point is further away. This is where the Robust design really excels.
The way i cut most of the time tool chatter isnt a problem very often. When your turning way out on the end of the tool rest the big Robust is stronger tban the 1" round bars bjt i find proper tool.control and taking the time go move the rest closer to the wood eliminates this most of the time.
There are probably other things but im away from my lathe and taking turns sitting in the hospital with my dad so my brain probably isnt all there and typing on my phone is soooo much fun. Still Woodcentral and other forums are keeping me sane. Other wise I'd have to read news about Hillary and Trump and even the drugs my Dad.is on wouldnt help .
