Ok ok ok ok ok I have chosen to make the dome part of my helmit out of sentra first of where can I buy it and how much is it. Also how on earth do you mold the stuff and if any of you have any tips for me I would much like to here them.
well, firsst of all I dont reccomend making the dome out of sintra. Secondly you can get it from US plastics, type it into google. Thirdly you dont mold it so much shapoe it and there are ample good articles in this forum on techniques if you use the search tab to find them.
The top of a batting helmet it tough, not terribly expensive, and wont fold at the edges like sintra will. The rest of the helmet can be done with sintra, but the dome is highly advised to not be done with it.
