Hoo boy do I ever have a lot of pictures to show you today! First, we get to look at the newly created mould for Zaapiel for the super cool Arabian Nights project. Yay! I am so very pleased with how it turned out especially because my vacuum pump was dyyyying throughout the process of degassing it. (Seriously, I need a new one. My wallet is sad. 😦 )
What lurks beneath this slab of blue goo?
It’s a sword! (As if anybody had any doubts about what it was… LOL) That’s the first side done. I actually managed to remember to take photos of the mould box this time.
Let’s have a little peek at the anatomy of this mould box here and explore some money-saving tricks! The straight parts near the handle are simple MDF board with laminate on one side to keep things from sticking to its porous surface. The wiggly parts all around the blade are flexible plastic sheet. The upside of using this sort of sheet, is that I can make it the shape that I need instead of one big rectangle every time. This saves money on silicone.
The downside of using the flexible sheet is that it takes longer to set up and it’s more fiddly. It also takes more hot glue to stick together and fill gaps. The wooden sticks you see are there to keep the plastic sheet at a 90 degree angle so the two halves of the mould will actually line up. The wire that stretches across the width of the box in three places helps those six reinforcement sticks from bowing outward when the weight of the silicone starts to push on the walls as it’s poured in.
If you choose to use this method of moulding, take a moment to consider how much you charge (or would charge) customers for your time per hour. Think about how long it will take to get the mould box the way you want it. How much will that time cost? Now compare that to the price of the silicone you will be saving by shaping the mould box more closely to the object you’re moulding. Which will be cheaper?
In this case, I saved approximately 100 euros of silicone. Since I charge 10 euros per hour for my time, and it took me less than 10 hours to fiddle with the mould box, I saved money by using the plastic sheets. Your results may be different, so it’s worthwhile to check!
Back to the pictuuuuures! Here’s the crazy silicone sandwich we all have come to know and love. I’m proud to say I didn’t have any leaks throughout the entire process. Gosh I’ve come a long way from where I began. It seems like only yesterday I —
… you know what, nevermind. Let’s go back to the pictures. Shush.
It’s a win! Two beautiful, bubble-free halves of a sword mould. I cannot wait to get resin into this baby and see what it can do. Will my new bubble-trap design work? Is everything truly straight and perfect? I don’t know! We’ll have to find out when I get my new vacuum pump so I can degas the resin properly. No skipping steps! That’s the way to get a crappy result.
Now, I mentioned birds in the title didn’t I? What was that all about? Well! I’m ready to reveal to you the beginnings of a new project. It has nothing to do with Shadowhunters. (*gasp!* I know. It’s crazy isn’t it?) This new project that I’ve been so secretive about is part of a creative vision that has deep personal meaning to me. I hope to share this dream with you so we can all enjoy it together.
If you guessed “raven” you are correct! This bird is fully baked now so the clay is hard. It still requires a lot of detail work, smoothing, and tinkering, but I had to render the clay stiff enough to support my sculpting tools fixing and fussing around on it without getting bent out of shape. The rest of the shaping will be done with either an air-dry clay or Milliput. I haven’t decided yet.
This project has a long way to go still, I hope you’ll stay tuned for its evolution. Until next time, wish me luck!
