I decided to use a Makita Die Grinder
When i designed my router, I decided to use a Makita Die Grinder #906H, 30,000 RPM dual bearing spindle, easy to repair, made from solit cast aluminum, not plastic! But most of all is was very slender, at 2.8" diameter!
I took the spindle nose casting off and used my lathe to turn it round, to make it easier to clamp on to!
The spindle has a maximum of 1/4" dimeter collet, but I made a reducer for 3/16" and 1/8" shank endmills and bits!
Dremel's are really nice, and not as noisy as my die grinder, but the ergonomic handle designs are impossible to clamp on to!
In my opinion!
