davecast Posted May 25, 2011 Share #1 Posted May 25, 2011 Hey all. First time posting here. Here is my little project i like to share. It is a fully scratch built Thomson m1a1 1:1 scale. Built out of foam then recast in resin. I used online blue prints and picture reference as my guide. here are the resin parts you might ask why I want to do this project..will the reason is that i am an expat working overseas. So where i am staying now any imported replica is a big no no. So i just decided that i should just build one for my own collection. let me know what you think. thanks Link to comment Share on other sites More sharing options...

Captainofthe7th Posted May 26, 2011 Share #8 Posted May 26, 2011 This is really cool!! Nice model making skills. What kind of resin are you using? These are huge parts...it must be expensive. Did you consider making the parts hollow? That's really a ton of res.. I had to cast some much smaller parts (I use oomoo 300 for the pieces and oomoo 30 for the rubber mold) and it ran me close to $100 for some pieces about the size of the handle on your thompson. What kind of foam do you use? Something like ren-shape? It's great stuff to work with. Rob Link to comment Share on other sites More sharing options...

What kind of foam do you use? Something like ren-shape? It's great stuff to work with. Rob for the master i used blue foam, and some wood. Carve the stock and grip and body then cast in rubber to make the mold. found a good supplier here for the resin i used the clear poly resin. Resin is cheap for a 20kg drum cost me $200....i can make at alot cast out of it. Took me a while but i figure out how to mix the right ration of baby powder to the resin. Due to the humidity and temperature here it is bit tricky. Actually i feel it weights like the real one....about 2kg of resin used. some has suggested that i need a vacuum chamber to get rid of the bubble however i dont have the money or skill to build one big enough to hold the mold, so to solve the bubble i mix in more powder to make it thick and now it comes out bubble free. to say for the experience it was a lot of work and planing and the resin fumes make me dizzy abit...i really need a good gas mask. now things that need to add on: 1-Stock attachment bolt....can do a mock one from hard ware shop 2-Sling.....If any of you got sling i am willing to trade one kit for your sling.

davecast Posted May 27, 2011 Author Share #10 Posted May 27, 2011 this was a stanag mag project that i also did in resin. this comes with painted round on top. Most guys here use to put these in their vest pouches during event to make it more real...since real stanag mag is not allowed here i have to make my own from scratch.

Captainofthe7th Posted May 28, 2011 Share #11 Posted May 28, 2011 Huh, I've avoided using blue foam for a master but these look great. Always used blue foam for sketch models and a renshape or styrene model for the final part to be cast. For a vacuum chamber, one of my professors says he just rigged up a vacuum cleaner and some cardboard boxes duct taped together. Apparently it works. But you seem to have the bubble issue worked out in the mixing. Rob Link to comment Share on other sites More sharing options...

Rob Blue foam is ok for me when i was working for an ID firm. good for sketch model i agree. renshape foam i cant get a hold of here....only got pink or blue. Thought about building chamber out of plastic containers and use my household vacuum cleaner but my wife would kill me for that...haha. Working on a vacuum form machine now. currently sketch building an m3 now. Link to comment Share on other sites More sharing options...
Jim MacDonald Posted May 30, 2011 Share #13 Posted May 30, 2011 That's some really nice work. How long did it take you to do the Thompson from start to finish? Mac Link to comment Share on other sites More sharing options...
davecast Posted May 30, 2011 Author Share #14 Posted May 30, 2011 That's some really nice work. How long did it take you to do the Thompson from start to finish? Mac Took me 3 days 1 night to do the master 1 day to mold and cure the mold then 1 day to cast and paint and assemble I did an early mock up in 2 days all out of foam and cover with epoxy... Not good but nice to check the size Link to comment Share on other sites More sharing options...

Jim MacDonald Posted June 1, 2011 Share #16 Posted June 1, 2011 Thanks for the info, Davecast. It probably would've taken me a month just to do the master. Mac Link to comment Share on other sites More sharing options...
davecast Posted June 1, 2011 Author Share #17 Posted June 1, 2011 Thanks for the info, Davecast. It probably would've taken me a month just to do the master. Mac The master was ok to do depend on how much detail you want to put in....i did not do alot of the details (since this was for my costume group here in Singapore and it is just used for events). I think i left out alot of details but i kept the general shape. The Thompson is more square shapes so it is easy to do...if i was going to do a mp40 or 1911 colt which has more rounded body it will take more time to do all the shaping and carving. Blue foam is very easy to work and shape with and can do it quick. Link to comment Share on other sites More sharing options...
