Overflow hole size?? - Page 2

To cut the hole bigger in acrylic you could also try a router with a straight cutting bit. Draw the circle you want to cut and be VERY careful to trim close to the line and keep a firm grip on the router. I have done this many times. The hole won't be perfectly circular but the gasket makes up for a lot. Gluing another piece of acrylic over the hole then redrilling a larger hole also works. If you glue the piece well enough you could leave it in place and put the bulkhead through both pieces. I have also done this successfully.

I used hole saw drill bits. They work well too. I clamped a piece of wood to the other side of it to support that area and it helped to cut down on burrs on the other side.

Just go nice and slow...

Speaking of going slow. JoJo never made it back after dinner! At least the Man has his priorities down!

i know i'm really late on the pics but here they are

also, i would like to drill holes into the back of the tank but the tank has a blue acrylic sheet siliconed or glued to the back glass. is there any special instruction to drilling through both at once, or would i have to remove the acrylic before drilling the glass?

I can't think of a reason you can't just drill through both.

How did you drill your tank? What did you use?

terry,i was thinking i could drill through the acrylic(inside) first then it would act like a template while drilling through the glass, any thoughts?

i didnt drill the tank, i bought it used and that guy bought off his dads friend so he wasnt sure either.
