I have a 24x40" aluminum plate which is going to become a router table.
There will be a 2" grid of 1/4-28 holes. Thats a LOT of drilling and tapping!!
Luckily, i can use hte CNC at school to drill all of the holes no problem, but the tapping is not so easy. I really dont want to tap these things by hand!!! BUT, we found a tapping attachment in the closet there, and we have the bridgeport to use it with. So i was wondering, does anybody here know how to use a tapping attachment?
There have been reports of people actually using a chuck on the spindle to grab taps, and use hte quil to feed a tap into a hole. If the tapping attachment does not work, i will give that a shot
