Anyone have a link for how to cut proffessional and neat holes into solid color tubs even possibly black cement tubs. I've seen on Heny pioruns' YouTube vid where the plastic seems to have been cut very neatly and a plexiglass window pop riveted in.

Also could anyone post a pic of the inside of their Freedom Breeder tub so I can see how their plexiglass slides in?

I appreciate any help.

Bob.
