Trying to make an ultimate sanding drum!

How about these....

Microplane Rotary Shapers

You could make a carrier to take several of them in a row - a 10 / 12mm threaded bar with spacers trapped between nuts easy enough to make up. They're fairly expensive but good quality.

Axminster have them in stock but a trawl of ebay might turn up something cheaper.

Hey FatFreddie, this is very interesting tool. I think rather than putting a threaded bar through the middle I might just put these shapers of my round aluminium bar. I might just give this a go and see what happens. Thanks a bunch man!!!
