Plexiglass Glue

On my canopy side vent, one of the brackets broke where it meets the
rectangular vent. I tried super glue, epoxy, plexi sealant from Lowe's...no
luck.

Fixed it beautifully using Weld-On glue, available from
http://www.stewmac.com/shop/Glues,_a...t.html#details

Glue is $5.10 plus $8.25 shipping.

If the crack is close fitting and tight, then a water thin solvent cement
may be best, as it will "wick" into the crack to provide a maximum surface
area bond.

The cement you mention is good too, as it has an acrylic filler it should be
better for bonding slight gaps.

In any case, it is advisable to remove the window track before gluing to
prevent glue getting on the canopy proper - - it will mar clear plexi if it
gets on the wrong spot. To help prevent this, the water thin solvent cement
is best applied with a syringe or similar as it takes very little.

One of our club instructors showed me a method that works well. Go to
the local hobby shop and buy a piece of brass angle, 1/8" X 1/8" X
12". Take the broken rail off of the canopy. Position the broken
pieces together and lay the brass angle on the corner edge of the rail
so that it will sit opposite of the sliding window and face inside the
canopy (toward the pilot not the canopy) when the rail is place. Cut
the brass to length so that there is plenty of surface area to bond
against the broken pieces. You may choose to cover the entire
length. If you need to notch out the brass where it meets a screw
hole, notch it with a file. With every thing lined up, glue it in
place with epoxy; take care not to get glue in the screw threads. The
other glues may work fine, we have always used epoxy. Let dry
completely and re-install the rail. Be careful not to over tighten
the screws. You won't be bothered by the brass when you fly because
it is located at a place where the thick rail distorts the view
anyway, so you won't notice a difference. This will hold for a long
time while you order a new rail. When the new rail arrives, give the
patched rail to someone that needs it or save it for next time a rail
breaks.

Good idea, Jim.

Fortunately, preventing these cracks is straight forward. I deal with a fair
number of these little windows while installing Quiet Vent kits for people
on the Minden ramp (gorilla marketing). I always check the tightness of the
rail and flip out window screws and find many that are overtightened. They
should be just finger snug, a few inch pounds of torque. Any tighter and the
rail or canopy will develop cracks.

Also it's a good idea to clean and lubricate the sliding window channels to
prevent wear and tear. I use a Q-tip swab, moistened with silicone spray, to
wipe the sliding surfaces.

Hell Bumper, I had not ordered one of your Quiet Vent kits because of
the high price. But now that I know that it includes installation, I'll
get the check in the mail!

Some of these repair methods seem pretty involved to save the +\-
$65.00 for a new set of rails (screws included!). I use a plastic
screwdriver (intended for adjusting old electronic equipment) for
tightening the screws. The plastic screwdriver (tuning wand) also has
the advantage of not scratching your canopy when it slips out of the
slot in the screw.

For the flip out windows, gluing it is very cost effective. $65 for a new
rail set vs 20 minutes for fixing a side rail seems cost effective to me.
