I need to modify the router mounting plate for my BT3000. It is setup with slots for a ryobi router (shocking, I know) and I have a newer Hitachi. I made a little convertor ‘plate’ out of a 1/2” piece of plywood but ideally I’d like to just drill the proper mount holes in the aluminum mounting plate so I don’t lose 1/2” of travel on my bits.
Here’s the manual picture of the plate I’m talking about
The newer Hitachi routers have a triangular hole pattern (two on one side, one centered on the other). That plate has those four slots for a router with four holes.
So, my question is how do I drill these holes? I have zero experience drilling in metal. Can I just use regular twist drill bits or do i need special metal ones? I do have a drill press so it won’t be an issue to clamp it down and get straight holes. I’ll also need to countersink them. Do I need to get a special metal countersink bit or will a regular one get through aluminum ok? Do I need to use water or oil when making the cut?
Thanks for the help! This place is awesome!
