Serious Project : Off with my Canopy !!!!!

[Sean H]

You probably will want the poly that has a layer of acrylic on at least one side for scratch/finish reasons.

 

[DAREDEVIL]

only Dr Schnell and the germans at Bayer beat Dr Fox to it by a week or so...

OFCOARSE THE GERMANS ,,,,,WHO ELSE,,,,,THE BEST !!!!!!!!!!!!!:sifone:

Dean, Dave - Do you recall what the thickness was on the poly when you stuffed the Batboat? And did you use the same thickness when you replaced it???

1/2" but it is mounted with bolts and gommits. The window area is also large.

 

[Wahoo 214]

yes, 1" thick.

The windscreen is epoxied and bagged into place, then the mask is placed on top and also fully epoxed/bagged into place. The windscreen is sandwiched into the layup of the canopy.

The flanges are between 6-8 inches all around the window opening(s). So if you see a 8" window height, that means the actual windscreen is about 24".

That install is interesting. I was under the impression that Poly is sensitive to chemicals like acetone or MEK.

Those will.

Will damage polycarbonate

Alkali bleaches such as sodium hypochlorite
Acetone
Acrylonitrile
Ammonia
Amyl acetate
Benzene
Bromine
Butyl acetate
Sodium hydroxide
Chloroform
Dimethylformamide
Concentrated hydrochloric acid
Concentrated hydrofluoric acid
Iodine
Methanol
Methyl ethyl ketone
Styrene
Tetrachloroethylene
Toluene
Concentrated sulfuric acid
Xylene
Cyanoacrylate monomers

It seems to handle Jet fumes well.

Epoxies do not contain those solvents.

 

[Steve 1]

It glasses in well, I use it for backing plates in some areas.

Cool.

Do you protect it by leaving the film on until it is sandwiched in?

 

[Steve 1]

No the little etching that happens never affected the material and its molecules are Chemically "Very friendly" to the styrene based resin systems. we are talking 30-45 minute time periods here.

When it is melted in a solvent (another project that will remain nameless) it gets very warm, a cool demo as the heat energy stored as bonds is released.

 

[Dueclaws]

Very interesting discussion!
I'd just like to find a replacement windshield for my pleasure boat at an affordable price.

Polycarbonate

"... eggshell strength under impact loading ..." :driving:

 

[Sean H]

some were asking about rollcages in canopies... here are a couple quick pics with the phone. interior cage and vertical supports to transfer the interior bars down to the stringers.

Gerry got a 3/4" piece of acrylic from Shields taken off the 55' MTI molds.

yes but its not acrylic, its the polycarbonate and your right on shields Rik there prices were good I quess.:sifone: whats cool is I figured out the angle last year 30degrees when I worked on a mold for Gerry, then we started again with gerrys bro the three of us had it 1/2 done and Gerry found Shields so I made another paper temp and his bro made the curve and sent it in. so we got to figure whats the best way to install it over the winter. art

 

[Ratickle]

That flat slight v is where i am going with my design, however much more support and i would assume thickness, than what i see here. these plastic pieces look to be secured only an couple inches all the way around and riddled with holes, I wouldn't suspect that will work.

Who do we check with to find out if X-Cat has to use the Lavin requirements like Class 1 ?

Art, it's Acrylic. 3/4" exact same as the 55' MTI.

Dont tell Pete, I would not want him to stop taking my agonizing phone calls.

Tell your friend Brad offers no support what so ever on installation.
