Start with a stock die grinder GD 0800C, Shaft adapter & wrenches
Remove Stock Nut & Collet
Insert Threaded shaft
Tighten new nut with wrenches. Be Careful, some carvers have over tightened & cracked their shafts! On the other hand it must be tightened enough so it does not create vibration. Good and tight, just don’t go crazy!
What a cracked shaft looks like. This was tightened too much.
