The test Dune egg is, well, done.
I’ve learned a lot, and there is probably still more to learn. Bear in mind that I’m doing the resin casting in the free space between a bunch of other projects (that I ought to write about). The folks who do these things on youtube tend to omit hours of prep-work to get the materials dry and sealed, etc, before they go into the resin. What you see is the resin being assembled and it all looks sooooooo easy.
It is not easy. It’s not hard, either. I see this sort of thing as a process that has a lot of “gotchas” but that will submit fairly readily once the time is invested in encountering them and learning how to avoid them or use them.
There are a lot of bubbles in it. So, what I should have done was stabilize the wood with vacuum-infused resin, which both drives the moisture out, and steals the wood so it won’t release air bubbles into the resin. I need to make my distribution of other colors more precise, too. What I have been doing is pouring the stuff and swirling it with a bamboo chopstick. A better approach would be to use a syringe with the colored resin and a hypodermic to precisely plant the resin where I want it. I need to sand things more carefully, and rig up a better buffing setup for final finishing. Sanding these is very unpleasant, since it loads the paper up very fast and it heats up and is very uncomfortable (to say nothing of dangerous) to hold – I don’t want a piece of sandpaper to stick to the resin and try to suck my hand into the lathe.
I want to learn how to get this stuff right, because I don’t want to keep wasting resin, and when kestrel finishes the sandworm model, I don’t want to ruin that.
Here’s a bit of “how to prep a hybrid” from Heath Knuckles:
It’s a kind of pretty piece for contemplating and it has a nice hand-feel and the bog oak looks great. It’s too nice to throw away but it’s not nice enough otherwise. It’s in that awkward category that I call “unloved art.” I am considering auctioning it, and the other two – they won’t fetch much but they might find a home. Or, does one of you know someone who would absolutely love a piece of flawed experimental art?
I have a few more tips of bog oak and I went on ebay and found a seller who sells miniature cast pot-metal swords. I am thinking that something with lots of green and fog I could make “The Sword In the Stone” kind of paperweight. Periodically, I pause and ask myself, “why am I even doing this?”
If you want to see what this can look like when it’s done competently, Heath Knuckles’ channel on youtube is full of resin composites. This one is the size of a bowling ball:
That’s a lot of momentum to be playing with. Keeping a work-piece on the lathe, when it’s round, is already tricky.
One thing I will be trying is, I saw another youtuber who simply took some silicone and made a mold from a burl. Then, they could make a resin burl instead of using wood (the wood is gorgeous, though!) – that’s a really clever trick that I think I’ll try, so I can make experimental faux-burl. Imagine a faux-burl of metallic gold swirl…
