Form for Castable
Here is a photo of how Joy and I made the form for the castable.
We used blue styrofoam and cut an arch shape with a template so all 16 of them were similar and then once we sandwiched them between the plywood form we used a belt sander to smooth them out.
Then we used clay to fill in the problem spots and we were ready to cast.

ReplyDeleteJohn, what did you use to make the initial cuts on the styrofoam? I bought a drywall saw to cut some but haven't used it yet. I'm afraid it will chew it up too much.
ReplyDeleteThanks.
I think we used a small saw blade used for PVC pipe, although it was tricky to keep it angled straight for each piece to be exact, which is why we ended up sanding down the irregular edges with a sander later.
ReplyDeleteWe used a hack saw blade on a handle. Like carpenters use to cut out nails on door jams.
ReplyDeleteAnyway you can mount the hack was blade>
Make quick short cuts,

So, I may have missed it, but have you posted how much castable it took and how much it all cost?
ReplyDeleteYo Kyle,
ReplyDeleteI am working on that.
I know I used about 250 pounds (or 5 bags) of castable and then the stainless steel pins and then the form and the bricks and the diamond lathe and the metal/welding, nuts and threaded rod.
I will figure it out and get back to you. Probably about $800 or so. Alot of the stuff was extra but if you don't have "extra" then it will cost something. I had a burner and a gas line, etc. A
By the way, What ever happened with the Bumper Stickers?
John
did you keep the form? is it reusable? any idea how much propane you used?
ReplyDeletei received absolutely zero designs for the sticker. i thought it was a fun idea, but i'm also a pottery marketing machine.
p.s wanna buy some pottery?
