Howdy,
I've been piecing together my first full build, an Ubersaw from TF2.
I've gotten over a lot of the hurdles, but after filling, priming, sanding in more iterations than I can count, I realize I don't want to have to do that again for when I return its twin (red + blue teams).
My question is do you have a suggestion on the viability of making a silicone mold of the main body? Current state seen:
I've made block and simple 2 part molds before, but the syringe cap (cylindrical piece molded to the blade) proves to be a problem since it is hollow inside and sealed on the back. it is hollow so that it will accept acylic pipe that will serve as the syringe's body.
I see that a 2 part mold with the blade lying flat on it's side would be the best option, but I fear that attempting to fill the syringe cap will just create a tight vacuum seal and wreak havoc upon removal.
The best options I see before me:
1) Still a 2 part mold, but allow one side of the mold to fill the inside of this syringe cap. Think a big thumb of mold rubber reaching from below the blade into the syringe cap to plug the inside of the mold. Reasoning: one piece of thicker silicone will be stronger, more resistant to tearing. Likely strongest mold, but also strongest vacuum
2) 2 part mold right down the middle, including the inside of the syringe cap. reasoning: if the silicone is already divided in half, the vacuum between silicone to part won't be perfect, and can be worked around. Weaker mold, weaker vacuum.
3) Attempt to remove the syringe cap, and mold it on it's own. the blade becomes safer to mold, but the issue of molding the syringe cap still suffers from the vacuum problem. Attempting to match up from syringe cap to blade will be imprecise.
If you've read this far, thank you.
Sages of the silicone, do you have any experience you can share about molding a shape like this?
