thought id detail it some. first off i went to wal mart and bought 2 metal hoops from the craft area, like 84 cents each, you want the big ones.
I cut a hoop to reinforce the back to make it round, and straighted 2 smaller pieces for the cheek areas, so they would go flat. I reshaped whith a single electric burner and a large pot of water (crank it up and try to make it boil) you want a pot big enough to submerge most of the helmet, if not all of it.
Reshaping took many tries, i screwed up a lot, but you can always reshape a reshape. I cut the hole in the T to let the water out, had a flat top and i filled it with boiling water, upside down, and let the weight of the water make it rounded. (i would suggest cutting lower on the T, closer to the teeth, for more water) held it upside down til the water was chilled (i suggest making a way to hang it.. my arms were tired lol) and it took well.
after getting a better idea of how it moved and everything, I used a plastic 2 part epoxy (like 3 bucks) to weld the metal to the helmet (i used almost all of it, its a great welding agent and very strong), holding in place til it dried (about 5 mins) did this slowly so it would be ok, after its in you can still bend the hoop and helmet if its not perfect, makes it nice to reshape.
now the fun part, buy a gallon of fiberglass resin and some fiber glass matting, you can get those inautomotive (i went to a auto supply for the resin, it was cheaper by the gallon, 30 bucks for a gallon or 12 bucks for a lot less) if youve never worked with this junk, well niether did i! lol I bought some cheap bowls at wal mart (4 for 3 bucks, various sizes) and
read all the instructions.
mixing the first batch (god dont forget gloves, nice thick rubber/latex ones, the fiberglass gets sharp when thin and dry) its messy so do this someplace you cant make a mess, and some wont ever clean up without another chemical (i forget its name.. its in the paint section.... gerrr) also use in WELL WELLL WELL ventelated area.
mix up a small bowl full, using the proper mixing on the instructions (yes.. measure it) it should be syrupy and sticky as hell. make sure before you add hardener you have PRE CUT 2x2 inch cuts of matting, some smaller, some bigger.
you want to paint brush on the fiberglass (after mixing the hardener in it) onto the strips so there kinda soaked, but not dripping, then you apply these to the inside of the helmet, VERY THIN (so your head will still fit) but still cover it. you ahve to work fast, the thin fiberglass will dry pretty quickly, dont worry if parts stick out or into the visor area, you can cut them out and sand em down later.
just "wall paper" the inside with very thin amounts of it, over the metal, when you get to it, start in one area, I dont suggest the middle buttom dome area, but a side, , then the sides around it and fill it in then the tip dome, reason, fiberglass will accumulate and begin to seep down into the middle dome, if it does and you apply more, it can get very thick down there, making it harder to fit your head in.
after you line the whole thing, i lightly brushed more fiberglass on top, and turned the helmet right side up to drip down and dry like that, making sure it stayed up right all night and most the next day. Itll dry according to tempeture and moisture, heat helps it, moisture hurts it.
I live in missouri and it was mildly warm and very humid that day, it took all night. when its done it still may be "sticky" to the touch, use something like baby powder and powder it down, the sticky will go away, or, do like i did, sand the fiberglass in areasy you need to, and use the fiberglass dust to powder it. ALWAYS WEAR A MASK GLOVES AND OTHER PROPER SAFETY GEAR!
K. I think I covered most of it.
sheesh i wrote a book, and it seems like a ton of work, but i did it in like 9 hours, including time to buy stuff (make a list of what youll need, go to walmart or a like store, buy it) total cost of helmet, including the original and paint and everything i used, with the 5 days of work (painting) was i believe 60 bucks. ( i didnt have bondo or fiberglass resin, or mats, so everything was bought) I still have enough matting and bondo and fiberglass do do about 2 more helmets though, so it was worth it.
also, here this has my pics and stuff, the site still hosts it.
