Outer glass for Speedglas helmet

[tysonn]

I have a Speedglas APC 3/11 auto darkening helmet.Its getting on a bit now but still works ok though no longer a current model.Having trouble finding a replacement outer glass.From the parts diagram on the 3M site its 90 X 126mm.Mothing this size on ebay.Is it just glass? i.e could I just go to a glazier and get a few cut?Sorry if I'm being thick.
TIA
Mick

Firsly if you have an auto darkening helmet the front lens will not be glass but plastic.

I bought a 1.5mm perspex sheet from ebay once and asked the company to cut it to size for me, You get quite a few lenses from a 2m x 1m sheet, plus they only charged a tenner for cutting

You can also buy one on a tad larger size and just trim it to size with a sander or similar

We discussed lenses a few weeks ago, they are polycarbonate, have a look here, clicky

You can usually cut polycarbonate with a pair of decent snips.
