Lot's of work to do on the courtyard, over the weekend - but found time to do a plaster "positive" for my visor...
View attachment 29188
Was my first try with that material and turned out quite well. I'll need to do some smoothing and straightening now to get a real nice and clean shape, and than will have to produce a "negative" in the next step in which I will press some heated acrylic glas. This should work nicely, if I manage to get it to the right temperature (too low = hard to get it to the right shape / to high = bubbles). We'll see if that plan will turn out as I wish... Otherwise, I'll do basically the same, but with a more basic shape and some filler to close the small gaps...
I don't really recommend pressing acrylic glass.
I tried it myself - didn't work.
In order for it to work you seriously need a vacuum table, the vacuum part.
Why?
When you heat it up, it will being to wave around and it's impossible to keep it straight and bend it up to your will.
I tried with different material and different thicknesses... and wasted quite few things thanks to that. :/
