how do I flatten the plastic of a 2-liter bottle into a sheet, with the ends removed? Answered

I want to make an Iris diaphragm out of 2-liter bottle plastic.  I need to flatten it into a nice sheet.  I have a heat gun and numerous torches. Spouse says no plastic bottles in the oven.

1. Wait until your good lady goes out.

2. Put the plastic between 2 sheets of cooking foil.

3. Iron with cool iron slowly increasing heat until plastic flattens (foil is in case you get it too hot.)

4. Clear up and make sure you put the iron back as it was so no one knows!

Wise lady !

After cutting the curved ends off, suspend the ring on a bar,
add a another bar to stretch the ring by wight or springs that pull down.
Use that heat gun.
