I have an old skill 1825 router where a few months ago I put a bit in it to do some work but never got back to it. When I tried to take the bit out I could not turn the collet nut to loosen.
The collet lock started to slip so I ground down a regular wrench to fit and that started to slip. It still would not budge. Finally I put the router on its side and supported the collet nut with some wood block then gave each side of the nut a whack with a hammer. This loosened up the nut and the armature shaft. I am a bit confused by the terminology (see image) and would think the armature shaft is what the collet screws onto. There are no obvious cracks or splits in any of the parts. I figure if I did crack or split something it would open up when I tightened the parts down. Anyway it is threaded for both the collet nut and the motor shaft, which is also threaded for it (at first i did think i broke something) My question is how do I tighten it (collet) onto the motor shaft. I'm thinking i need to disassemble the router further but what can I grip to keep the motor shaft (armature shaft?) locked and from spinning as i tighten the collet to it. I also thought of sticking a screw driver through the case into the fan but I did not want to bend anything considering it spins at 25k or so and thought it much wiser to ask before I have shrapnel everywhere including me.
