I have a pre-cracked (bottom pane) 20L that I plan to try drilling a practice hole before I do my (good) 20L sump, 30g fuge and 75g display. I see a lot of people use duct tape on the opposite side of the drilling to catch the glass hole that pops out. Would I be mistaken to think duct tape on the drilling side as well would be a good idea? I’m using a 45mm diamond hole saw.
Pros – Holds the bit in place better and my thinking is that the tape will assist with cracking prevention
Cons – Gumming up the bit, friction heat adding to the gumming up of the bit (I’ll have a water dam for cooling, but still the adhesive on duct tape is pretty gummy when it gets hot)
