progress today. made an oven out of an old locker, two heat guns and some insulation
made a flat sheet raised on blocks to circulate the air
you can see template in the background
trial piece worked but had imperfections. so I decide to use a piece of cotton sheet to lay the screen on. This worked great and made it easy to pull out the hot screen which I lay over the template and held in place until cool. If I do it again I will make a positive and negative to help keep the shape while cooling.
this is the sheet cut oversize
and formed
couple of picturess with the template on still thinking of the screen size and toying with idea of removable wipers
