Thanks guys for the kind words. Bj, the box is mounted on a removable cover which gains access to the switch and a couple of capacitors, and there is heaps of room behind. That's just one more reason to have a superb router like the Makita 3612C!
As for other routers, when making it, drill holes in the base to suit whatever router it's going to be used on. For someone like you Bj who has tried to corner the router market, have such a base on a dedicated router.
