Looks good Bob - the canopy fits very nicely on your model.  When heating plastic I try to follow Tom's sag method, but I get it wrong as often as I get it right.

I would agree with Mike...you need to lift the mold off the platen by putting scrap balsa 1/8" to 1/4" off the surface.  This really helps eliminate the those stringer that come off the mold's edges/corners.

Tom, that is how I try to do this. It seems that I wait too long with overheats the plastic, but practice will make me finally get it correct. I can live with the canopies as they are for now.

Bob... I believe the plastic needs to heat to the point where you can see it tighten up and then begin to sag.  When you see it sag it's time to plunge it over the mold while the vacuum is running.  I hope this makes sense! Smiley

I tried another canopy and was successful some. The heat needed to be on HIGH since MEDIUM did not work.

I just need to read the plastic when to pull off at the correct time. Before the plastic turns opaque.

Trimmed the finished plastic canopy to fit perfectly and glued it in place. Next once it has dried I will attach green tissue to form cabane frame work.

Mike, I had a 3/32 piece under the canopy. But I wonder if the heat temp. that I am using is too high. I have been using the HIGH setting on the elec. range. Should I use MEDIUM instead?

Bob,

You may be able to avoid those puckers if you put an undersized piece of 1/8" or 3/16" scrap between your mold and the platen.

Well! The canopy is ready and I wanted to finish this Bf109 plus the F4F by vacuuming the canopies and attaching them today.

But, not to be. The plastic did not act well the first time (or I did not let it become molten enough to completely go down the sides of the mold) so I reheated the plastic to try again Tongue

It did not go so well take a look. Ill need to set up some more plastic tomorrow and try again.

Looking good Bob...if it gets too cold outside you could always hook up the vacuum cleaner hose to the base of the sander and turn it on before the sander and sand away and let the vacuum suck all the sawdust into the cleaner.  Noisy but doable!  Chilly around here, this time a year!

Ok! Time to get off my rear and finish this airplane.

The canopy is taking shape and a piece of 3/32 was added to the front to fill in. More will probably be added to the front and bottom to make sure when the canopy is vacuumed it will have enough area to cover the edges of the cockpit.

OH! I finally used the belt sander correctly by moving it outside. Cheesy

The canopy will really set this one off. I like the light blue underside, but it makes it less visible in flight. Markings and everything really look good. Well done! Smiley
