With a curved tool rest on the inside of a bowl you prevent the “overhang” of your gouge from becoming too large. You can place the tool rest closer to the wall along the entire inside of the bowl. To achieve this, the support is also slightly tilted on the shaft, so that the wood does not run against the bottom of the support.
Robust tool rests always have a hardened top. This ensures an always smooth surface to allow the tool to run over. So there are no dents or deep scratches in your tool rest. A huge plus!
The curved tool rest is 30 cm long and can be supplied with a 30 mm axis or a 1 inch (25.4 mm) axis. (Select in the pull-down menu).
