Where are you buying the bubble canopies for the Beryl like the one on Daniels Beryl? Does someone in France make them, you making your own? Also cowlings for the Beryl.

Thanks,
Roger

Hi Roger

You can contact the member "Poulet", it's Daniel himself

He known the answer

Laurent

Thanks, I sent him a pm. Do you know if he speaks any english?

Roger

Hi Roger
I don't know about english, if not, ask me, i will translate for you

Hi Roger

I saw in your pictures gallery that you will build your canopy yourself ?

Tell us more with pictures if you can.

Great job too about your engine

Yes Roger, i've also seen this stange picture named vaccum box for canopy ... I would really like to learn more on this since today the canopy is the last part on wich i really have no idea how to make it ...
We 're waiting hearing from you ...

I am taking pictures as I go but so far I haven't made a successful canopy. I will post a couple of picutres today of the heaters and the vacuum "shop vac" that I'm using. I hope to try to vacuum a canopy tomorrow "Saturday". I will keep you guys posted on what happens.

Roger

I tried last weekend to vacuum form a canopy. The box I built wasn't strong enough and I will build another one that is reinforced with metal.

Once I heated the box and acrylic sheet up to 325 degrees I turned the heaters off and the vacuum on. The canopy started to pull a few inches but the vacuum was pulling the sides of the box inward so hard the box collapsed and I lost vacuum pressure. I will try again after I build a new box in a week or two.

I will keep you guys posted as I make any progress.

PS: I got to try Hang glidding this past week while on vacation at Kitty Hawk NC.

Roger

Thank you roger for your tests very valuable for us (at least for me ), you make the science of building an airplane progress ...

What do you use for vacuum that can colapse the plywood box ? a primary vacuum pump ?

Chris

I tried to pull a canopy this weekend. It only pull to about 13" tall before it cooled down below forming temperature. There is a picture of the canopy in my photos section. I will try again this week or weekend to pull another shot. I will keep you posted on how it turns out.

Roger

I stretch formed mine over a male mold, the windshield has a flat front like the plans, which I thought was cool as heck. The Pazmany book "Light Airplane Construction" was my main guide on doing the canopy that way. My first choice was to work with a canopy company but wasn't able to find one that would mess with it, they seem to favor the blowing method, but I didn't want to alter the look of the original design.
As for cowling, I got a nosebowl for a T-18 from Aircraft Spruce and did the rest with foam and glass.
