freefalle 0 #1 October 19, 2007 the plaster mold of my head hardened very well. I filled in the nose piece with plaster pieces and let it dry over night. The next step was to coat the inside and the outside of the plaster cast with resin. I wasn't sure how this was going to come out for two reasons, first I've never really worked with resin and hardener before . Second, Matt cautioned me against putting the resin on too thick because doing so would decrease the size of the mold when I fill the cast with expanding foam. So after I got off of work this morning I went to Walmart to pick up most of what was left on the supply list and when I got home I set off to work. Coating the plaster cast with resin and hardener really wasn't that difficult. the store I bought the resin and hardener from sold pumps the screwed on top of the cans. These took a ton of guess work out of mixing resin and hardener. three pumps of resin three pumps of hardener per the directions. I coated one half using 3/3 then I coated the other half using 3/3. It MAY be a little too think but we will see, I'd rather have to go put on another coat than have too much there. The plaster mold is now covered in resin and is drying, when I wake up If I need to add another coat of resin I'll do it then Lessons I learned today,- take your time, be patient. watch what kind of cups you but, I tried to add a little acetone to the mix so it would spread better the acetone ate the cup..... oops shit So far I have ALMOST everything I need to complete the project except knowledge and Im up to 438.00 is cost. that not every thing yet so Ill add more to the cost as needed Quote Share this post Link to post Share on other sites
The111 1 #2 October 19, 2007 Acetone will indeed eat a plastic cup. I'm also not sure it makes any sense at all to put it in a resin/hardener mixture. In fact it could even prevent the resin from curing, I'd guess. Wes recommends polyester resin for the sealing of the cast and the mold. It is cheaper than epoxy and cures much faster I think. It should not require mixing pumps because it is less ratio-sensitive. If you have leftover resin in your cup, when it fires and cures it will get VERY hot and will eat through the plastic and even could start a fire. It is best to mix in a metal cup (cut in half soda can) but I didn't do this... I just put every plastic cup in a stack of like 5 more so it wouldn't be able to melt through all of them as my excess resin was firing.www.WingsuitPhotos.com Quote Share this post Link to post Share on other sites
