Hey guys! I am really excited and nervous today. I’m using my brand new vacuum pump and taking the final mould for the Clariel model sword. (I hope.) It has taken way longer than I thought to get that plaster sword prototype as smooth and shiny as I possibly can.
The glossy varnish I have needs about 12 hours to fully set before I can put on a second coat so you can imagine how long it took to get multiple coatings on and then polish the thing.
I think it was worth the extra effort. 🙂
Now, the next step is getting it fitted into the moulding box nice and snugly. That took a long time as well. Why? Because you saw how sloppy my first mould was. Let’s not have a repeat of THAT nonsense! We want the two halves of the mould to line up all straight and smooth and beautiful so that I can easily clamp them together with no leaks or weird seams.
To do that, I have to find the exact middle of the object I’m taking a mould of. That’s tricky when it doesn’t sit flat on the table. It’s chubbier in the middle than it is at the point of the blade or the pommel (butt end). So that makes it do a see-saw thing when I try to lay it flat. To compensate for that, I have to put a cushion of clay under the blade and the handle to make it sit perfectly level. Then, I have to cut a piece of laminated foam (or anything else that’s flat really … could be wood but I used foam) to fit in the space between the sword and the edges of the box. That’s so the silicone doesn’t fall down through any gaps and fill the whole darned box. That would trap the sword inside and I’d be really sad. (Hey! Give me my sword back!)
And that gives us exactly one half of Clariel to make exactly one half of a mould. Yaaaay!
But what’s all that green stuff in there? No one said there would be green stuff aaahhhh! Don’t worry. that’s just clay. Some of those clay noodles are touching the sword and some aren’t. The ones that are touching Clariel are air vents. Those allow the bubbles to escape from the resin when I pour it into the mould so (hopefully) they get out of the sword and don’t get stuck in there.
The noodles that aren’t touching the sword are what we call “findings”. You know when you’re closing a plastic container of leftovers and putting it in the fridge for later? Take a look at the lid sometime and you’ll see there’s a trench all the way around where it fits over the edge of the container. That makes a nice snug fit so air doesn’t get inside and so you know the lid is in the right spot before you push down on it for that nice satisfying “click!”. Container closed and ready to go. Like your plastic sandwich box, the two halves of the mould need to fit together nicely and the findings help you figure out when both sides have lined up just right.
And then I pour 300 Euros of silicone into it. Haaaaah … yeah send me Luck runes guys! You can probably see why I’m a little nervous of screwing up! Haha!
Well, that’s enough procrastinating for me. I’d better go Iron Brother it up in the workshop. (I’m just kidding. I love talking to you guys. LOL) Oh, and if you’re a Matthew Daddario fan like me, don’t forget to wish him a happy birthday if you haven’t already!
Ciao for now!
