What spindle would I need for the united kingdom

There is a european version of the dewalt611. The name has slipped my mind but I`m sure someone else will drop it here in time.

Alternatively, check out the Makita rt0700c router. Works like a charm for me.

It can be used with the dewalt611 mount and a couple 3d printed spacers.

Also, John Scherer can set you up with a custom mount for the makita router. Check the threads below.

Best of luck, hope to see you posting some assembly pictures later!
