In this video I' m trying to show how you can make a simple glass helmet if you cannot find to buy it in the market. ( old model - no name helmet etc).
You need a paper to get the stamp from the old glass . an angle ginder to cut the plexiglass , a solder gun to make the holes , files, sand paper and a heat gun to make the curve. It' s a very strong cheap simple glass with simple curve (not double) and no UV protection. The material here is a piece of 2 mm thick plexiglass.
