How do you resin cast a steering wheel?

[GMP440]

I wanted to ask those that do resin casting; how do you do a mold for a steering wheel?

[Chief Joseph]

I do them as a two-part mold; I place them into a clay bed and build up the parting line to the centerline of the rim and center section. Put in some spacers and wires for gate & vents, then pour first half. When first half is cured, remove clay bedding and pour the second half. Works best with a firm rubber like 30A. You can get away with doing a 2-part squash mold if you don't mind resin getting everywhere when you pour the casting and rejecting every other piece because of bubbles.
