Wax fixture for casting tires

[Lownslow]

Casting tires is a headache molding is a bigger headache especially when making multiple molds of the same part it gets really annoying to make the same setup out of clay, after some thinking i came up with this setup its not 100% permanent but it wont get destroyed after one pour.

Youre gonna need wax,double boiler set up, basic clay tools and some shapes to pour them in

rather than trying to carve a circle out of wax i used the master itself then its always a perfect fit for the most part you dont have to mold release anything but the cup and tire.

first get the wax nice and melted

pour a little into the cup and master the tire it cools in about 20 minutes

after their both cooled solid use some melted wax to seal them together

heres the part on the fixture once poured i can flip the tire and re pour a new mold

i got lazy rather then using glue to fix the base to the mold box i poured some wax in there to seal it

here it is without the mold box.

Great tip. Quick question tho, what type of resin do you cast with? I have been working with Allumilite, but I need something with a little more working time.
