i broke the collet of the dremel. (a new one i ordered won´t get here until weeks). and since i use the dremel like my toothbrush (daily-ish): improvisation kicks in.
here is how to operate your rotary tool without a collet:
Step 1: Reducer-tube
to prevent the bit from wobbling inside the shaft: create a quick and dirty tube. here i use the lid of a fish-can (disclosure: i adore fish-cans. a gift from the gods)
cut a strip, roll it up to the size (depending on the thickness of the bit you will use)
Step 2: Compression Ring
to prevent the bit from spinning inside the shaft:
fabricate some kind of compression ring. here i use a small piece of stranded electrical wire with the insulation kept on >> the rubber will prevent slippage.
Step 3: Assembly:
insert tube into shaft of rotary-tool
push lock-nut over bit you will use
then push the compression ring over the bit inside the lock-nut
insert bit into the tube inside the shaft & tighten lock-nut
ready to bring down the universe
