Topic tags/keywords: router sub bases diameter

I only own three routers and I am trying to build a jig that I can use when/if I get other routers. My routers are PC 690, and old Craftsman, and a Bosch Colt. The PC and Craftsman have the same sub base diameter while the Colt has a rectangular one that replaced with a Plexiglas one the same diameter as the PC and Craftsman. I don’t want to make new sub bases for routers I may buy!

My question are:

  1. What is the brand and sub base diameter of the routers you own?
  2. If the sub base is rectangular, what is the brand and what are the dimensions?

Thank you in advance for your input!

The only way you’ll be able to guarantee the new routers work with the jig is to build a baseplate for each. Or buy the same router.

They don’t have a standard to meet, but I did happen upon 2 that have the same size base. The PC 690 and the Milwaukee 5615/5616 routers have the same size base. Other things swap as well, I use my PC edge guide on the Milwaukee routers, and the wrenches are the same size. But as a rule that is just not common. I suppose some of the other PC routers have the same size base as the 690…but I don’t have any to confirm that.

make a sub base larger than any router manufacturer would, then make your jig to accommodate that. That way you only have one sub base (with a bunch of different holes for mounting in it :) )
