Why buy something that you have to modify for its use when there are lots of versions out there that don't need work to make it operational? however I agree about the Muscle chuck in any router and lift, good solution to the awful double spanner collet locking, one Allen key is so much more convenient.It is only a pain in the knees if you don't remove it, just get rid. .... In this case you remove the switch interlock and collet lock mechanism and fit a Muscle chuck. This is probably the best setup unless you go all out for the AUK setup.
