Skaliwag...

Dickeybird and Matchlessarrow used to talk about shrunken coke bottle canopies.

The RCU Tips and Techniques forum might have a thread about it, too.

I've read about it several places, but have never done it. You make a buck of your canopy with enough of a base on it that you have to force it into the bottle. Then you heat and shrink the plastic until it suits you. I don't know how much heat. Maybe a hairdryer or monocoat gun. On one of the forums there were photos of fairly small green plastic canopies done that way.

There was quite a few posts about it here on RCU but the new search feature is one of the "improvements"

I've had good luck doing searches on Google for info like this.
I've got a [very cheap] Harbor Freight heat gun that would easily do the job.
I can see how starting with a snug fit between the bottle and the plug would make this idea work best.
Something tells me that having a pair of wool gloves on hand would be....uhh......handy.

Like CP posted, Google searches are many times more productive. Use the following search term with Google:

shrink plastic canopy site:rcuniverse.com

You may choose whatever search terms you wish, but the site:rcuniverse.com will restrict searches to that one domain. I've found that Google's search engine, when targeting a single domain, is usually better than any other third party search feature.

Carve your canopy buck, cut the bottom end off a 2 litre flat sided PET bottle , wedge the buck in place with a large piece of lumber under the buck, start shrinking with the heat gun. Thats the bit that takes practice, work slowly. It will take a couple of attempts until you get the feel for the shrinking.Both of these cowls and the canopy shown are from soda bottles . Also you can make wheel pant halves, wing tips etc.using this method.
