Yah bro, I thought about the foam core. The issue is that its a mold with a cap. Im going to pick up a bit of foam, and try pouring one, but the seam line needs to be near invisible. Reason being is it has a _real_ wood grain texture. Any sanding ruins that. Therefor the seam is on the butt plate around the edge of it.
Ive thought about hollow roto casting it, and then drilling a couple of vent holes at the cnc'd part where the bracket attaches. That way the holes are covered by the bracket.
In all, realistically without this thing being 'injection molded' its hard to get every bubble out, but im trying to make sure that There is as little cleanup as possible.
Especially in the high profile areas.
Ive gotten quite a few pm's asking about individual pieces. Which I dont mind selling, but I need to clear it up.
The mold will be good for roughly 20 kits (barrell mold, stock mold) which use a LOT of silicone. Now, it could last till 30-40 but this batch wasnt de-gassed, which will improve the mold quality a LOT.
The reason the larger molds dont last as long is because the larger the piece, the more heat that is given off from the part. The more heat, the shorter the parts life span.
Each barrell I sell means one less kit. So when I break these out and offer up the pieces, they arent going to be dirt cheap. They are going to have to be a % of a full kit.
Lets say that the kit is $175 each. I need to break it down into the parts and sell them accordingly, because each major piece I sell, is in fact, a whole kit that can not be created.
Because if I sell 5 barrels, that only leaves 15 kits. I can see selling 5 spare bronze grips, and bodies, maybe D brackets, less stocks, and even fewer hammers, trigger guards, backplates/risers etc.
So I guess Im warning that ill post a price on individual parts, in different materials, but expect, a barrell for example, to be $40-60 shipped. Depending on the material etc. Which isnt cheap. But unfortunately I have to do that, because the break down on this project is really pretty incredible.
So far:
Gun $1700+ (Thats the BID but theres a 10% premium, shipping, documents, etc)
Plastics/Rubbers 250+ (100 resin, 100 rubber, dyes, powders etc)
Silicone $500+ (The gun oil inhibits platinum resins, the tin I use is 144 a gallon. HS3 from Alumilite)
Clays, releases, box materials $100
So to this point, not including 100+ hours i have $2550+ into this.
Not including humidifier, vac chamber, vac pump, and other things that are 'tools' and will depreciate over 10 projects.
So once I sell 15 guns, if I price them at 175+shipping to keep them to your door under $200, ill be even on materials (except ill have to buy more by then

. (Granted I still own the gun
So I guess my point is, I love to share. Im the kind of person that wants to share things I have with people. Id have to sell 50-75 of these to make the kind of money that I could make doing something else with my time. Like web software. Which im MUCH better at
So understand, when I, and or any of the other people here like FP or Alex, or MOW or anyone that theres a lot more that goes into it than the '$10' in resin.
Really the people to thank for this project are Chris (FP) and my daughter. Because the profit I made from the knees, and the last 10 orders of helmet foams that my daughter helped me with, all that money went into this.
And its well worth it, as long as everyone appreciates the work thats put into it.
That being said, im off to redo the grip mold. I see what I did wrong the first time, and I think I can REALLY improve the results. And im waiting on the D-Bracket and triggerguard mold to be completed anyway
Thanks as always for the interest.
