Yes I would like to own the crack but it's unsafe now new ones are dear enough to make it worth making my own. Especially seelng how it's one rock one crack I may need more.
A few changes
And cut it out
Bend some wire to get the bend
3mm ply screwed and glued then smeared with plaster filler
Madstrad screen fits. I have done some experimenting with acrylic off cuts and think I know how the sheet is going to slump.
Lay the flat screen across the dish and angle two paint stripper guns one from each outside to heat the outside first. Point to the centre of the dish so the air flows to the centre. As the acrylic heats it's going to bend away from the heat as it heats it expands.
Thing is, the right way is to put it in an oven and to do that I'll need help
