Ok so double tapping.
I have a brand new $800.00 137G tank, manufacturer calls it a 150, PFFFT. I hate that.
Anyway to my point, it has an internal overflow, the bottom glass has been pre drilled for two one inch lines.
Yes I can deal with that IF I have to, butt has anyone here ever drilled a bigger hole over the existing hole?
I want to install two inch and a half bulkheads.
I don't see a problem in doing this. Clearly the glass is not tempered or the existing holes would not be there.
So I thought I would ask and see if any R2R members or glass workers that may be reading this might have any advice or a reason this can't be done.
Thx in advance. YouTube failed on this subject, plenty of glass drilling videos just not cutting a second hole over the existing one.
