Default Shop Press Polycarbonate Shield

What's the standard thickness of a polycarbonate shield for a 100 ton shop press?

Most of the shields I've seen are metal mesh. Does your Worker's Comp office by chance have any specs for shields? They may have guidelines and/or regulations. If you use Lexan I would think that 3/8" would be enough but it depends on whether or not the press is ever going to be inspected...

It's a homemade press that will be in my backyard shed. I'll mainly be using it for forge welding and not quite sure what else.

Whose standard? East German? Africa? India?

Here in 'Murica, we gauge thickness by the fractional inch.

I have never seen any form of plastic used anywhere near a forging press.

Ask Allescense.

Expanded metal is what I used on mine and I would do the same on yours, 100 ton is a big press, what size ram and how much pressure are you running?

The plastic will be quick and easy for remove. It's a general use press, but I'll mainly be using it for forge welding. Having the protective screen is more of a just in case I need it type of thing I won't have it on during forge welding.

The cylinders won't be powered by a hydraulic pump. It's an experimental design. It might fail to produce enough pressure, but in that case I'll convert it to run on a hydraulic pump.

Plastic is easier to remove than other materials? How bout when it gets dirty and scratched up?
