Help Req in casting Heads

Custom WorkstationHi,
I would like to try my hand at casting heads.
I would like to find out, how do you guys setup a mold for a head and to maintain its peg hole
Do you
- Use 2 pc mold?
- Use 1 Pc mold?
- Is the mold for the head upside down when pouring or rightside up?
I've read a bit off the web and also watched some youtube videos, but am still not sure what is the best way to go about casting a head
Any help or info or link to a decent website is much appreciated!
Rgds

Please wait...

lol this is hard to talk about without pictures.
Generally a 1 pc mold is what you'll want for casting heads. I've heard of people using 2 pc molds, but I have yet to see a head I can't mold using a 1 pc.
Generally you will be pouring the molding material onto an upside down head. This allows the material to sink into the neck hole and it prevents airbubbles from forming under the nose. Air bubbles are to be avoided at all costs so you want to position the head upside down since it minimizes bubble when molding, and also while casting.
Honestly it seems a lot more complicated than it really is. Once you do a few of them you'll get the hang of it in no time. Also don't be afraid to mess up a mold or two, it's part of the learning process and everyone does it at some ponit.
