Hi,

My 4020 has two large holes for coolant to drain from table. These get plugged up from chips all the time. Newer machines have slots running toward the back. Im considering plugging my holes and cutting the back of the table out to make it like the new style. See pics for the difference. Anybody ever done this? Guessing it should still be plenty strong with a hole and a slot right? Any thoughts on if its safe to do this?

Assuming it is safe, any suggestions on most efficient way of doing this? Would have to be done by hand of course, not removing table and bringing it to another shop or anything. I dont mind finishing with die grinder and rotary burr but what about getting bulk of material out? Thanks.

Mark
