Thanks

As long as the piece is flat on one side and that side doesn't need to show detail, (such as a turret hatch) it can be done, do it all the time!
I am writing an article now for Armorama that will explain step by step one part and 2 part molds. If you can hang for a day or so, it will be submitted.

It was just some gunshields I want to use for some OIF hummers I have and some t-62 or t-55 Iraq skirts. I was also thinking about some OIF updated ring stuff.

I'll wait till your finished with the article it's no rush I was just thinking about it.

Thanks for the HELP.

Happy Modeling

there only needs to be a section to use as the pour block...... I have some torso's that are detailed on almost all "sides" other than the leg arrachment point.

True, if the piece doesn't have hard undercuts, is cylindrical in nature, etc. it can be molded one piece. Examples of this are, as Matt stated above, torsos, or say, my finger. A crude example, but should give you an idea of the kinds of objects that don't require a 2 piece mold. As an example, if I were to cut off my finger :-) at the highest knuckle, then I stood that finger on end in a long moldbox with the tip pointing up, I could pour my silicone over it, covering the tip. When cured, I simply remove the finger from the bottom side and viola, there's a finger mold!! 1 pc, easy. It's Friday!!!!

I am writing an article now for Armorama that will explain step by step one part and 2 part molds. If you can hang for a day or so, it will be submitted.


I have done all my molds (a very limited amount) in one piece because I am not sure how to do 2 piece correctly. I am looking forward to reading the article.

As far as doing your stuff in one piece it could work, but would probably do better as a 2 part. On large items with a flat side, like side skirts, you have to do a lot of sanding to get the open side level and the item to the right thickness. That's why I say 2 part may be better, a lot less sanding and probably less wasted material.

There are many pieces that are just impossible to do as a single part mold, such as figures or this for example. This is one of the tower guns from the deathstar.



Anything with undercuts that would lock the piece into a single mold, needs to be a 2 parter.

The article is almost done.
