RE: VACUUM FORMING IDEAS
All kinds of sources. Start with the phone book---yellow pages. Look under "plastic, rods, sheets...".
Depending on how big Lawton is you may have to try other cities. Expect to be told that you need to buy a full sheet, 4' by 8'. They are usually pretty cheap. You can have the warehouseman roll the sheet for you so that you can get in into your car. Also, hobby shops usually supply some types of plastic in small sizes----but relatively expensive on a per sheet basis. Regards.
