So wasteful with the resin. I haven't found the best system for pouring the resin into the mold yet, so I always need to make more than I need to account for spilling. The resin has an odd (I don't know the word) "attraction" to other surfaces. It wants to glide along the edge of whatever it is poured from (even if I make a spout), so I have to pour off to the side, and it will run down to the bottom of the cup into the mold. haha.

I think I will get a syringe the next time I need to cast resin.

Fantastic work! You can use a syringe to pour the resin too. It's what I use. I think I use 10ml and 30ml for larger things

Thank you, Ben! I'll definitely pick up a syringe before I cast resin again. Do they last a while? Like, should I plan to go through a bunch of them, or should one do the trick?

That skull is a beautiful, elegant shape in its own right.

I use a syringe with needle to fill tooth moulds, so I can inject from the bottom and avoid a big air bubble trapped at the tip.  I've done it with thinned down latex, and with polyester resin.  Otherwise, for moulds where the filling hole is a bit small, I sometimes make a funnel by cutting the bottom of a plastic bottle, and pour into that.

Thank you, Nick! Those are some great tips, too. When you say tooth mold, do you mean for casting teeth, or is that a type of mold?

Fantastic, keep up the great work

Yes, a silicone mould made from a sculpt of dinosaur gums and teeth, so I can cast the set of "dino dentures" in resin.  Normally you get an air pocket at the bottom, so the tooth comes out with the tip missing. Squirting the resin into the bottom with a needle fixed that.

Nice work Will, that head looks fantastic. I found measuring the volume required exactly and then mixing the exact amount needed so you can pour away using soft plastic container so you can pinch to help control the speed and can pour straight down. When I did that it worked much better than the first go when I tried to control the speed by tipping back and experienced what you are talking about lol A big thanks to Ben and Nick for the great tip on the syringes. I was casting some insulator caps(not sure the proper term for the little devices the wires sometimes rest on on old telephone poles) I was using the flat end of a pushpin to try to quickly scoop the little bubbles at the bottom to the surface before it set but I can't wait to try the syringe! :) Cheers

Nick, how do you clean out the needle? Or do you?

Comment by Mike on March 21, 2014 at 10:01am

I'm taking notes. :) I'll have to try some new approaches on my next resin casting.
