Interesting. But a 1/2" inch belt? I have a 1" belt sander/grinder and it can be hard to control without cutting into the work with the edge of the belt. Still it's interesting.
Know of a good source for 2" or 3" hook & loop MM disks? Then I could use the same sanding attachments I use for bowls and other turnings. Otherwise I'll just stick to what I've been doing.[]
