    Re: For those that want to try to cast heads but havent yet.

    Featherhorn, my statment about silicone not sticking to anything was not correct, of course silicone sticks to stuff, we use as a everyday sealant and adhesive. What I should have said is that many things will not stick to silicone when it has dried except its self.
    If you are using synlube as a release and are using the plain old silicone ( not siliconized accrylic or the newer elastromastic types that are out there then it should be working for you as it has for myself and many others. What brand and type of silicone are you using.

    I used the GE 100% silicone like you said in your tutorial right?

    Yep, thats the stuff. Have you tried to cast a fresh frozen head yet? Give that a try and see how it works for you. Its possible the cast head that your trying to recast has something in it that silicone really wants to stick too. But even with a good coat of synlube on it, it should be releasing for you. I usually recast a cast in a RTV silicone once I'm happy with it, but I have recast a headcast using the plain old Wallmart silicone without issues. Sorry I don't have a better answer for you. Let us know if you get it figured out

    I get mine from Van dykes. I havent tried anything else but the synlube, its not expensive and will last a long time.

    Well, GE has two kinds of 100% silicone. Version I and version II. Version I seems to work okay, but I don't know about version II.
    I don't know what caused my latest attempt at casting a head to fail, but it MAY have been the fact that I mixed the two different kinds of silicone together, or it may be that version II will not set at all if mixed with paint ... I dunno. But what a mess. (My Walmart only had one tube of GE silicone version I left.)
    I have to try to salvage this mold, regardless, because this stupid bird is too huge to use a commercial head.

    I don't know either, but I managed to scrape off all of the goo and then I scrubbed it good with xylol.
    I re-coated it with version I and it set up properly. 'Just got my first pull out of the mold and it's a keeper, although I don't know if a second pull will be worth the trouble or not.
    It was from a 27 year old mute swan - huge and gnarly as all get out. His beak knob was so texture-y that it grabbed a lot of the silicone and tore it loose. I don't know if it's worth bothering with making another one or not. What a pain in the neck this thing has turned out to be!

    the head will just slide out of the silicone I assume? How many times can you use the mold or is it a use and discard?

    it is great that the veterans are helping out newbies thanks. i have been talking to locals that pour there own heads they were telling me they use epoxies/bondo mix is this better than fiberglass? what kind of epoxy would be best? is their a price benefit either way?

    I did two merganser heads with this method...my first try and they turned out great as far as detail. I didn't use the 50/50 blend of bondo to fb resin and they came out a little sticky, we'll see if they dry out over time. Do the tutorial EXACTLY like Jeremy wrote it and it works. Good job Jeremy! Also, when your in the auto supply store buying fiberglass resin, make sure to buy an extra bottle/can/tubes of fb resin hardener. They only give you a little dinky tube with the resin and it doesn't take much but I needed extra for the mix to harden. Also, a piece of scotch tape around the bill and a spritz of water in the mouth before freezing helps keep the mouth shut. Also, my molds weren't as thick as Jeremy's but they still came out great. I kept it thinner with the small pointy bill of the mergansers. I taped my molds back together with duct tape but I think hot glue would be better now that I've tried a couple. Hope that helps a little.
