Well who would have thought that an old dull starrett wood/metal holesaw and a handful of sand/water would grind through glass.... My $10 powerfist drill definitely paid for itself today. The hole is a bit oversized but I put a bead of silicone around the inside and the sock fits nice n tight. 
 
 
Success has been achieved for $0
