Hello Mike!
Well I say you should give it a try, it opens wholly new possibilities to a modeller.
Please be careful about those frames, they look way too thick for me.
Then again the shape you're going for looks rather easy, and if you like, you could try something like that:
- Carve a shape that would the canopy out of wood. Smooth it, cover it in a layer of CA, sand smooth again and then cover with liquid soap - works great as mold release agent.
- Put your carving on a holder, so that you can have it a few inches above the working surface. For example you could glue it to a popsicle stick that could be held in a vise - this or a similar arrangment.
-Take a piece of clear sheet a few inches larger than the canopy itself - for your canopy a strip like two inches wide and five inches long would do just great. hold it by the ends with both hands
- heat the middle of the strip until it gets visibly soft - but don't let it melt through
- while soft pull the hot spot over the ooden carving. The plastic will wrap itself around the carving, let it cool down
-after the plastic is hard again, cut the canopy to shape. From there on you work with your new part like with any other.
That's how the process looks like. With some practice it's easier than what you are doing at the moment. Gives cleaner results, too! Good luck with your build and have a nice day
