What specific saw do people use when cutting the hole
For the frame sliders?
I'm trying to find one that won't rip it apart and make as clean of a cut as possible.

 

just use a fresh saw, cover the area with masking tape before you cut, and take it slow. the smaller the saw teeth, the better.

 

Drill a pilot hole, then dremel.

 

I used the circle cutting tool it worked awesome

 

A company called Greenlee makes a specail hole saws for fiberglass.

 

hell no on the dremel idea thatll come out uneven. regen nailed it. tape it up and use a saw with the smallest teeth you can get and youll get a nice clean cut. A pilot hole will help out a lot if youve got a holesaw piece with a drill bit in the middle otherwise dont bother. But itll definately be easier

 

Link?

 

the trick to using a hole saw in any thin material is to back it up with a block of wood or something. Otherwise, the pilot bit won't have anything to guide it as it makes the last of the cut and it will wobble.
