« Part 6: Constructing the mother mold part 1b Part 7 of Casting from an original carving series Part 8: Pouring the casting material - the end »

Yes, yes, I know I have, LOL.

I can tell you now that as of Monday, I never thought this week would end!

My stubbly haired arms are burned from acetone(and shaving, haha), I have dried plastic stuck to them and many silicone balls hide in corners of the house. However I’m hoping that my efforts will make further castings a breeze.

You can help my by crossing your fingers that I have indeed applied enough mold release or I’ll be asking one of you for a chainsaw to help me finish this blog!

.....tick tick tick, Okay, here it it.

My first chore is to pry the ‘entire’ item from it’s table, then I will use my Dremel to lightly machine the outer edges so I can get a clear view of where my separation lines are on the mother mold. It is easy to grind.

Then I gently pry the pieces where they separate easily until all are removed.

I actually ended up with 7 pieces – one broke but it’s in an area that is easily belted together.

Then I draw cut lines on my rubber and while I’m actually cutting, I make sure the cut lines are where I won’t mind trimming excess resin that seeps out of those later.

Wanting to keep the rubber in one piece, I gently pull it away from the gourd which was pretty easy on the outside but it had adhered to dry plant material on the inside so it was a bugger to remove with so little room to move my hand around.

It’s in the laundry sink soaking right now and will later be examined for bubbles and thin rubber areas that might need patching.

The gourd remained unscathed.

Thank you so much for your interest. Next step will be tomorrow as we test out the mold with resin.

I have few questions about holding the inside during material casting. But I am going to wait, I am very sure you have more than figured out how to do it.

Ian, I am just going to lay the rubber back into it’s shell and clamp all of the shell pieces together. I will pour it upside down. There will of course be a bit of seepage from the cut lines but the resin or wax dries faster than anything that could flow out.

I’m not sure I undestand all that’s going on here, Jordan. So I’m going back to your first blog and study it step by step.

COOL procedure!

When you say “Clamp”, are you, in a way, saying you’re going to wrap it with Packing Tape (or something like that)?
