So I drilled my first hole!
I bought some drill bits off ebay from hongkong dealer lau
48mm and 38mm for 1.5" and 1" pvc parts though the 48 mm is a little snug it still turns inside the whole easy enough.
I used a scrap piece of glass I had lying around, for a coolant ring i cut the top part of a cd spindle(too big for use on a tank but ill find something smaller), used water, and started drilling w/ a cordless.
at first it skipped a lot so i made a 1/3 moon groove first, it worked out well.
its really easy, esp after the groove is made. i cant believe i paid 25$ for a lfs to do it.
