How Not To Make A Silicone Mold

Setting up my mold box.
I don't do vlogs... I actually hate the word "vlog". Being the grognard I am, it actually took me a long time to even accept the word "blog" into my vernacular. I will never accept the word "vlog". It's just... wrong.

But here it is in 2016 and I decided to do a video of my misadventures in crafting. I decided to try my hand at resin casting and thought it might be a hoot to record myself screwing up while doing so.

 I wasn't out to make a comparison between buying something like Dwarven Forge and making your own pieces using Hirst Arts or Sculpy, but I did have some intriguing personal discoveries related to cost and effort along the way.

A clipboard was  probably not
the best base choice... but the
board bits will peel off with water.
#1 - First and foremost, mold making is not cheap. If you are going to cast a lot of pieces often, it could pay for itself eventually... but for the odd bits and ends, you end up spending a lot more time and money than you might have anticipated in silicone and resin.

If you like to make a lot of terrain accessories, it might be worth it, but if you think you are going to save a lot of money because you are not purchasing pre-made resin pieces, you may be wrong.

#2 - Related to #1... You will probably need a lot more silicone than you initially think. One pound of silicone will create a 6" x 6" mold only if none of your pieces are more than a 1/2 inch tall or so. As your mold gets deeper, consider that the volume needed is cubed. Try to stick to smaller pieces when you first start out before you jump in completely.

The mold came out pretty good but
used much more silicone than I expected.

It's a bit long winded since this was my first foray into... video blogging... but if you were curious about making molds casting resin pieces, this is a reasonably good beginner's prospective (IMO).

By the way, I skipped directly to part 2 because I recap most of what I said in part 1. If you are really interested in seeing me babble on for about 10 minutes, part 1 might be mildly amusing.
