Default Vacum forming questions

I was wondering if anyone had some recomendations about what are the best types of plastics for both clear canopies, and opaque plastic detail pieces? I am going to try some of this before to long, and I am not really sure what thickness or material I want to aquire from the plastic store...I am kind of psyched up about the whole process though after watching some utube videos, and seeing what others both here and other places are making. It looks like a lot of stormtroopers and Daft Punk fans out there!! and why not !

PetG is recommended for clear parts, and high impact styrene for other stuff. Micro Mark sells a book that answers the questions that you haven't even thought of yet. Well worth the $15 or so.

For clear canopies, I think 0.040 PETG works the best. You can buy a 4 x 8 foot sheet at a plastic distributor.

Thanks for the info, I finally have a picture of my yet unused vacum table...I have some canopies and part molds started, but nothing nearly ready to make a nice piece..so more finish work ahead ! Two overhead heaters from home depot,acrylic table top from an old aquarium project, mdf board from a slot car track build ! angle iron from an old bed frame I think...and the top boards were some scraps from the garage door repair last year , ha ha Oh yeah I am using a 5 horse shop vacum (eventually) and I installed a airline fitting for possibly using some real vacum off a tank later.

Unless you plan on doing this commercially, you are spending a lot of money for a few parts.

I use a shop-vac connected to an 8"x12" box and I heat my plastic on a frame suspended over 2 hotplates. Total cost was about $25 (mostly for the hotplates).

I can pull a 5" x 8" x 3" high windshield from .040 PETG with no problems on this setup. (The hardest part was making the plug for the windshield)

It isn't fancy, but for the 10 or 12 parts a year I need it does the job.

ha ha, maybe !

No matter, a buddy and I are always making oddball planes ,pilots, heck I may be making slot car bodies... I won't have a hundred bucks in it when I am done, I always have lots of materials collected up (scrounged) We needed to make some 22 inch long canopies, I didn't want to build that big but we can easily make a two piece one with this. It wil really help making blisters, gun ports, exhausts...We are building LONG TERM a couple big me 410s, and we will need lots of parts in at least the quantity of 4's so it will help out there as well. I have so many irons in the fire I am not sure when I will get my darn molds ready...and my plastic bought..Wish I could go fire it up and start pulling parts right now.
