Alright then.
First of all, there is no canopy making molding laws. This is just how I decided to do it on this particular canopy.
So I cut out a profile of the canopy and traced it onto some foam. I then used my wire cutter table that I made a while back. I only cut the bottom profile at this point.

Next I cut a piece of ply the exact shape of the canopy where it sits on the deck. My foam is 4" wide. I glued the ply on the bottom of my foam on that curve. There's a special adhesive for that to not eat the foam.

Next I cut the top curve on the wire.

You'll have to visualize some of this. I market the center on the new curvature (top of canopy). To that I glued a piece of ply that is shaped like the top of the canopy (from the plans).
At this point I have a solid piece of ply on the top and bottom. I used the wire cutter to trim the foam very close to the ply. Then used a sanding bar to get the foam even with the wood.

Next I peeled that top piece of ply off. I used a file to shape the cockpit area.

Coated the whole thing with epoxy

Hogged out the cockpit.

Frosted the cake with faring. This is where I left off. I'm sure I'll be doing this multiple times.20150222_105348.jpgNoisy personComment

Very Nice Terry!!!! Thanks for sharing. This is something that I would like to try some time. Like the hot wire foam cutter. I need one of those too!
Later,

Hey, this is just how I have done a few of my lids. The last one being my Pursuit lid. Works great, a bit of elbow grease goes into it but you get that 'one of a kind' charm. Good work T!Comment

I rigged up a really crude foam cutter to drag across the top of my Whip 40 cutting the excess foam block that was above the framing before skinning the top. I just used an older 12vdc AstroFlight PS, wire for foam cutting I bought 10 yrs ago and a haaaaaandheld wood frame. It saved me so much time and mess sanding. I did have a couple minutes of fine sanding leftover. Maybe I'll start a thread asking how to power foam cutting wire properly.

This stuff. Sorry, it's fairing compound. I use it as a filler. It's basically micro balloons and cabosil. Pretty sure.Noisy personComment

Sanding and fairing and sanding and fairing.
In this pic you can see the first dose of sanding. 80 grit with a bar and then a little block for the tight spots. Every place you see a dark spot is either a hole or a low spot. Added another layer of frosting.

Could have been an easier way. If I had framed it and skinned with wood it would have been less finish work but more front side. Compound curves this tight are annoying in wood. At least for me they are.Noisy personComment
