I am new to this and am starting with a rubies Jango Fett helmet. The visor in it sucks and I want to cut it out and replace it. I have seen people mention getting a welders shield and cut it to fit. I am afraid I will cut it to the wrong size since I do not have a template. What would be the best way to replace this visor? Should it be flush with the inside of the helmet of fit exactly in the space that is cut?
Thanks for your help!
