lost wax casting

Anyone used fiberglass mold to cast their wax model?

ck - Tuesday, August 25, 2009 - 7:46am

Is it possible to use a fiberglass mold to pour a wax? If not I suppose I'll have to pour a fiberglass model to make another mold from. Any suggestions or experience out there?

Designs for a wax burnout kiln

burnout | casting bronze pour | lost wax casting

I am wondering if anyone has plans or suggestions for a wax burnout kiln? Currently we are using a kiln which is constructed out of an oil drum, which work well, but it is loaded from the top making it difficult to get the molds in and out of the kiln. Majority or the bronze sculpture object which we are casting are within 6"-2.5' in height, so I was thinking of a front loading design might be a good approach.

Which casting technique to use?

lost wax casting | sandcast

Hello,
I'm new to this stuff but have been pondering and reading about casting for some time now. I rebuild saxophones as a hobby. My desire is to fabricate brass levers for the neck octave of certain types of saxophones that would be very time intensive doing it by hand forming out of brass plate. My question is which method to use? I am presuming that those who read this don't know what the octave lever on a Sax neck looks like. The lever is bent in an arc, probably that of a 12" dia. circle, it has a loop in it, much like an elongated noose. It is hinged close to the center where it pivots to close and open a vent in the neck. It is only about 1/4 - 5/16" of an inch thick and has various degrees of shaping to the looped end. I can't really be more precise other than the shaping is contoured in an arcing fashion so instead of just square sides to the piece of brass it is shaped to an edge on the loop end. The other end is the "rope" part of the noose analogy and has a little cup at the end of it where a leather pad would be inserted and glued. If I were to flatten the arced original piece it would be approximately 8" long. I am assuming I'd have to make a flat copy out of some material to use as a form? I would like to get as close to the original confuguration as possible as the contouring at the noose end as described above would be quite difficult to match and make consistent by hand filing/sanding.

Cores for Ceramic Shell Casting

Casting bronze casting | bronze sculpture | ceramic shell | core | lost wax casting

New here - hope I'm doing this right! I have a question about cores for ceramic shell casting. I teach a foundry class, so I am no newbie. Generally for hollow pieces I cut out a section or make sure the piece is designed so that the center will build up a shell and be able to dry properly. But, I am now doing some foundry work for another artist out of my studio of some small animal figures. These are a little too big to cast solid (though I can if necessary), but a little too small for a large enough opening to allow the shell to make a strong core -- soooooooo.....I have been looking into using some sort of core material.
