Members,

      For those of you who  intend to buy either the vent that requires a 2 & 1/2 inch hole or the vent  that requires a 3 & 1/2 inch hole the following information may be of use to  you.  I ordered two of the Vista-Vents that require a 2 & 1/2 inch hole  and when I checked my hole saws I found that the standard set does not have  either size (2 & 1/2 or 3 & 1/2 sizes.  All of the larger hole saws  in the set are even inches with no half sizes.  I called the tool  department at Lowe's and was told that hole saws are available there in 1/2,  1/4, and 1/8 for all of the larger saws therefor if any of you run into the same  problem, remember you can get the 2 & 1/2 or the 3 & 1/2 inch hole saw  at Lowe's.

back when I did this kind of thing for a living, the standard practice was to cut the hole at least 1/4" smaller than needed and drum sand to net diameter. Several advantages here:



1. You can get the best fit diameter with the drum

2. Minimized risk of cracking the transparency

3. You can final polish the hole and "bellmouth" or flare the inner and outer edges to minimize chances of cracks down the road.
