Hi Dave,
Thanks for the comment~
As to the rapid changer, I used it now and then. Since my router (makita) has variable speed, I can keep the speed down. It needed to be played with when locking it in the motor collet, but once finding the sweet spot, it is well balanced. It just sticks out so far and feed rates have to be kept low as it loses its accuracy with too much side loading.
More collets are needed for it but the system supplier support kinda dwindled and the prices went high.
I still intend to try my luck at turning collets on my lathe. I expect a lot of scrap metal after that..

Hmmm. The rapid changer is good for multiple tool changes... in fact I was going to make one of those tool changer racks that sitt along a side of the router.....just never got too it.
