LF-Someone with a Diamond Hole Saw and experience

Drilling isn't as bad as you might think, but you have to be very good with a drill to free hand it.

You need to drill the whole way as close to 90 degrees as possible, otherwise you are going to get 'blow out' on the backside of the hole.

Last night I was drilling a 20g, 3 holes .. Almost zero blow out, I was impressed! (Tank #6 under my belt), but of course there is drill from both sides, but very difficult.


BTW: Get the bulk head before you drill. Depends on the style, they need different hole sizes.
