Cast hinges


#1

Hi Rick, please tell us about casting pieces with hinges and
latching mechanisms. Thanks!

Well this is some model work for a client who up opening a
jewelry shop here. The pieces are sort of a locket that needed a
latching mechanism. The concept is her’s, the prototypes were
sloppily (and poorly) done by a “famous” designer in NY. I
remained calm and held my tongue… (The client is adept in
drawing and design, and easy to work with)

I’m using a hook that pivots out and when closed engages with a
notched post. The hinges will be simple- 3 nuckles on each of 2
hinges. My caster has some creative mold makers- they like to
make multi piece molds- they’ve been casting for Stuben Glass for
25 years. I have options like a steel rod in the rubber mold to
align the hinge holes in the waxes. The other (NY) caster I use
would just throw it back at me…undone of course. Nice to work
with pro’s.

Hard to say no to an intriguing problem.
