I searched and didn't find any real good basic install tips and things to be careful about.

I've watched countless videos on youtube and pretty much grasp all the prep and shop vaccing the air out etc but just want any tips on doing all the return flange cuts, skimmer cuts, main drain cuts, light cut, and stairs cut.

Stairs is the main one I can't seem to find anyone talking about!

I'm trying to absorb as much as I can so I don't make a $1200 mistake trying to do this myself!!!!! :-)

Thanks!
