Does anyone know of a place where I could buy 2 1/8" and 3 3/8" hole saws" I want to install gauges in a fiberglass dashboard, and I cannot find any hole saws in these sizes. Thanks for any info.
home depot , they don`t have 3 3/8" but they do have 3 1/4" http://www.homedepot.com/Tools-Hard...splay?langId=-1&storeId=10051&catalogId=10053

I cut four hole in my glass dash with a hole saw but the oversize speedo took more work. I drew a circle around the gauge on the dash and drilled a pilot hole in the center. Then carefully cut out the hole with my jig saw - ended up with a rough edge but this is covered up by the bezel on the gauge. So far so good!
+1 on Fat47's suggestion. Find an industrial electrician who builds panels. He can hook you right up.
Some electricians might use hole saws, but mostly they use punches - either hydraulic or hand powered. They work great on sheet metal, but not at all on fiberglass. They come in conduit sizes, not fractions. I used them for my Auto Meter gauges - they get you a nice round hole and close to the size, then 1/2 round file after that.

make sure your arbor is true and the saw is really REALLY round. old abused equipment is notorious for making holes way to big lol, never fun to deal with. A couple people sait it already but its generally a safer bet to go a bit smaller and file your way up, do it by hand or be really careful and use a burr bit edit: just saw your dash is glass dont use a burr bit lol it'll take material away to fast. just use a file
Thanks everyone! Found what I was looking for. Seems like H.A.M.B. is where I always find answers that I can't find anywhere else.
A trick that works for me is to drill pilot hole ( 3/16 or whatever comes with the holesaw) without the holesaw...clamp a short piece of round stock the same size as the pilot hole into holesaw in place of pilot bit to use to center the sawn hole...less chance of wobble and a cleaner hole
