Hi
I've got a million different dremel tools, but something's missing, a backing disc for the 0.99 million sandpaper discs. I've realised I can make this with a bit of sheet plastic in a standard drill, which will rotate slow enough to permit it to be tooled to an accurate disc. The q now is what plastic to use? I'd rather use something lying around than go and buy.
My first though is any slightly flexible thermoplastic able to withstand hot water, so maybe a bit of polypropylene washing bowl or similar.
Any thoughts?
