I'm in the process of mounting a canopy on a GP 330L
The front curvature of the canopy doesn't have the same curve as the front bulkhead/deck.

Screwing or forcing the curve would put stress on the plastic and cause bowing elsewhere.

Any suggestions ?

Would a heat gun help ?

Thanks,

I have the same issue, I plan to put a small trim of wood to give it a surface to be glued to, If you plan to paint the trim on the edges it will hide it well.

I would trim the canopy to match the curvature of the foredeck.

The easiest way to do this is to first protect the inside of canopy from any scratches using a low tack masking tape then wrap and tack a piece of sand paper to the foredeck and Sand the curve to match by sliding the canopy back and forth. You will be able to get an exact fit with very little time or effort.

I have used this method for many years and have not found anything that is easier.

Lenny, your sheeting looks real nice.

I'm building that kit also and started working on my canopy last night. I plan to extend the forward turtle deck sheeting under the canopy. The picture below shows a similar canopy I built for a Goldberg Extra. This gives you a little more material to attach the plastic to.

I am also in the process of building this plane.I glued 1/4"x1/4" rails down the top side edges of the cockpit floor.I also had the same bowing thing happening.I first marked my center.Then I used medium/gap filling Ca (I should have used oderless Ca to avoid smoking!) around the front.then the back.Leaving enoungh unglued on both to be able to lift the sides and lay a bead of glue all the way down the rails.This way I got a solid bead all the way around.But,the bowing was preventing me from getting an even bond.So I used a 1"x1/2"x 12" piece of hard wood to keep an even pressure the entire length.Only problem was the Ca took 5 minutes to kick off.It was a very long 5 minutes of holding pressure down.There was some smoking even after I cleaned it good.
I bought my Dad the oderless and he had no smoking problems.He did his the same way and it came out nice.
The Ca works exellent.The wood will break before the Ca does.
I say 5 minutes was very long.Can you imagine what it would take with some of the other kinds of canopy glues???
lennyk,I am sure their are many other ways.I think this is the fasted and strongest.Save the punch out for the hole in the back and use a couple of drops of thin to hold it in.Paint it with the rest.Looks nice and can be opened for access inside for whatever reasons.
