You may find that an ER collet nut wrench fits the bearing locknut... It does on a lot of the smaller RF mills and clones, I know because I've used them for the job!
The ER32 or ER40 wrench may just fit that nut, if so next question: How are you going to hold the shaft to get it off? The smaller mills often have a slot for a tommy bar - beware though, the slot's usually in a piece of Chinese top-quality hardened putty, so make sure the bar's a *good* fit or be prepared to do some tidying up with file and stones afterwards...

Hi Dave,
Unfortunately my collet chuck did not come with a wrench. I had started making a similar wrench for my 9x20 lathe some time back but got rid of the lathe so the wrench never got finished. Well it did today and I made use of it.
I tried holding it with my gloved hand and striking the wrench with a dead blow hammer but that didn't work. Then I realized I had a wrench for holding the spindle while tightening the draw-bar. It worked like a champ.
