I have acquired A Contraption. It's not a sex thing.
It's a tumbler spinner! The idea is that you put a cup or tumbler on one of these arms and mount it to the motor which slowly rotates and allows for an even coating of resin after you decorate it to your liking.
I don't really use resin all that much but I do like to make my weird little jars that still need a coat of sealer on them, so it'll still function basically the same way, just with varnish. I'm also hot gluing some corks to the ends of the arms so that I can do the same with clay pins (once I get back to making those)
I'm not super thrilled with the raw particle board construction of it though, so I'll probably have to paint this things before I use it.
