As I recall when I saw Doug Dugger install his vents he hand-turned a fly
cutter and lubricated it with WD-40. Of course you will have to drill the
pilot hole for the fly cutter using another drill bit and follow all the
normal precautions in drilling holes in Plexiglas. And keep the canopy as
warm as possible. Also test WD-40 on some other piece of Plexiglas in case
my memory is faulty.

I used a fly cutter mounted in a brace. Make sure the canopy is warm,
start on one side and finish off on the other and then smooth off any
sharp edges.

I need to put two 2.5 inch holes in the Plexiglas on my canopy to mount Vista Vents. Any ideas, Tips or blade suggestions.
And yes one of them is to get rid of a crack that developed when mounting the canopy.

You can also scribe a circle on the acrylic, and cut it out with a dremel
with some cutter wheels, and work to the edge with sanding drums. This
pretty much guarantees you won't get cracks. It's a pain in the butt, but
safer on a canopy than a flycutter. You can also make a circle in some
light aluminum, and masking tape it in place as a shield to protect the surrounding plexi/lexan.
That's how I have done them. It's a lot safer than a flycutter. Also with
the sanding drums you can gradually work to the edge, and trial fit the
vents as you go which is pretty important since you don't want them to
be too loose.
Regards,
Jeff

Someone may have already said this, I haven't been following this thread.
The way I did it was to cover the area with masking tape, draw circle, drill
big hole near edge with a step drill bit. Then cut out circle with a jig
saw using a metal cutting blade, nice and slow. Works every time. LRM

Bryan, you, of course, can do what ever you want, but I would not use a fly cutter and any power drill. If I was going to use a fly cutter I would use one with two cutting bits and an hand auger. Never touch plex with any kind of saw. You might survive, but chances are it will crack. Have you contacted the folks that make the canopy for their suggestion? Good luck, Bill of Georgia

I didn't use a power drill, I used a brace.
My fly cutter only has one cutting but, a two bit cutter would probably
be better, but mine worked, You just have to patient and use a light touch.

It's an antique hand drilling tool, also known as a bit brace. Here's
some at Amazon: http://tinyurl.com/27zhq9
and another: http://seattle.craigslist.org/see/tls/605653279.html
I'm pretty sure the one I used actually is an antique, but new ones are
still being manufactured. I seem to recall that I had to modify the
shank of the fly cutter some to get it to work in the brace. I rigged it
up a few years ago when I was still building the plane and just left the
cutter in the brace since then.

A lot of people may not know what a brace is. Not a very common drvice in these days of batt. powered portable tools.
I think I sold my last one in a garage sale several years ago. It was a mistake.
