Drilling for pitmasteriq

[madbbq]

I'm a little late with a reply but i just installed one of those lamp tubes (1/2" x 3/4") through my weber this weekend.  Used blue masking tape and drill a pilot hole 1/8".  Then finished it off to 1/2" with a uni-bit.  Coating did not chip.  I did however drill on the low speed.  After, touch up with some ceramic manifold paint i picked up at the auto part store.
