So I got the Kitplane Article written by our own Bruce Eicher and am trying to fashion a couple of canopy bow mirrors.
I got some 1" PVC and cut it to the dimensions in the article. This morning I took it to the plane. The PVC is essentially a "C" when looked at end on.
I slipped the PVC over the canopy bow. It fits ok but rattles a little bit - it's not a tight grip. I figure it will vibrate.
I'm thinking of putting some 3/16" wide, 1" long strips of adhesive-backed felt pads on the inside of the "C" to make things snug. This is the stuff you put on the bottom of furniture legs to keep them from scratching the floor. I'll let you know how that goes.
I had a crummy acrylic mirror and I glued that to a piece of PVC with some silicone adhesive after cleaning both with lacquer thinner. I expected the adhesive to fail because PVC is so slick.
When I tried to pull the mirror off, the mirror broke. The joint was solid. And I didn't even scuff the pvc surface.
I ordered some "shatter-proof" acrylic PVC from Amazon:
Acrylic Mirror Sheet - 12"x12" - Silver - 3mm(1/8") - Laser Polished Edge with film masking - Lightweight Shatter Proof Durable
Sold by: Acrydeal
That arrived today. 12x12 should give me a few tries
So next I'll cut a rectangle from that and shape it. I traced the shape of the canopy bow this morning.
I'll report on the results. I've read and re-read the article to try and understand the dimensions of where the "C" is glued to the back of the mirror.
