I appreciate my Coote grinder for the value. However, the rest is a real pain, requiring the platen to be removed to install or remove the rest. Here is my cheap solution. 2" tube drilled and tapped and bolted to the side of the machine, set screw in the top and 
1/2' plate for the rest. Works really well. I very rarely used the original rest or it's capability to do angles, preferring to make jigs for such issues.
