Quoted from BrianZ:I use my hair dryer and two plates of play field glass. Works great, and i don't have to worry about melting plastics in the oven. Once you have it mastered, it doesn't take that long.
So, how long do you need to hold hairdryer above playfield glass ? I have a very warped plastic that I would like to be flat!
Quoted from boilerman:with the hot weather here, I put two sheets of PF glass in the back of the suv with the warp plastics between them.
let them sit all day with the windows up so it gets hot in there.
the next morning when the suv is cooled down you can take out you perfectly flat plastics, no work or damage to your plastics
the only downside summer is the only time this works
How hot does the outside temp need to be for this to work?
Quoted from Shoot_Again:Low heat sandwiched between two pieces of glass. If it gets to hot it will melt the plastic.
Tried this on a big time warped plastic.
Hairdryer with diffuser on top of the glass for 5 minutes. Then glass is very very hot. Put blanket and heavy book on top for around 4 hours. Really great result! Flat again.
