I knocked this up originally to see how effective the Munro system was/is.
It has become a handy little item for cleaning up the bottoms and sides of fairly deep hollow forms. I use it on flower vase type hollow forms, so they are not too deep.

The shaft is 12.5 Stainless and has a slight goose neck bent in it. The cutter is a Munro cutter and I have made the movable shield on top out of mild steel. Its very basic but performs well for what its used for and is simple to make.
