Plate for Router table
I am building a router table and one the of the items I purchased to accomplish this is a blank aluminum plate sold by Rockler for my Skill router.
I removed the plate attached to the router by 4 screws and plan on drilling 4 holes into the plate to attach the router.
My questions is: How can I best countersink the screws into the aluminum plate? I have some countersink bits, but they are specificly made for wood and I do not want to ruin them trying to drill into aluminum. Do I need to buy a countersink bit specifically made for metal? Suggestions for inexpensive way of getting this done?
