Great idea!

very nice!

That is an awesome idea :O I been wondering how to do that. I'll be making a deer character soon.
Did you have to drill out a bigger hole in the horn, stuff a screw in, and then fill in the space with some glue to anchor it in?
And how on earth do you attach a flat bolt/nut to the head?

I bought a coat hook rack that looked like a pair of antlers and did a ton of modifications to it: I cut off a few points and used clay to smooth out the corners. Then I made a silicone mold of the modded antlers and cast them in resin. As the resin cured, I set a screw post into the resin so it would cure around the the screw.

I made a rigid plastic base for the top of the head and locked the Tee-nut into the plastic. This is what a Tee-nut looks like: http://www-img.toolstation.com/imag.....bbig/41724.jpg
As you can see, the spikes hold the nut in place, so I pressed the nut spikes into the plastic so it would hold and used some 5-minute epoxy to ensure it held tight.
Then I added a layer of sheet foam to the both sides of the nut so it would add a nice cushion to sit on.

Once furred, I simply cut out the fabric around the nut hole so it was exposed.

Oooooh. Hm. Maybe I can get the person I'm buying the antlers from to cast a screw into them.
I'm going to be working from a resin head base, so i was a little worried the resin wouldnt be thick enough to hold the antlers.

If they can't, your method of drilling a hole, inserting a screw and filling the gaps with epoxy would work just fine.

Interesting way of doing it!
Are the antlers meant to be removable, or it's just a one-time method of attaching them?

They are meant to be removable for storage and transport.
Antlers take up a LOT of extra space if you can't take them off. Plus, you get the added bonus of playing a doe if you don't want to be a buck ^_^

Heh yeah. I know, it's the same thing with my horns (with regards to the storage & transport).

This is a fantastic idea! and they look great as well I am at some point going to need to resin cast and I'm terrified... is this process incredibly difficult? I've looked at a few tutorials online and I'm hoping all goes relatively smoothly

It depends on what you are casting.... 1 part molds are very easy, 2 and 3 part molds can be very hard/frustrating. These antlers were a REAL frustration for me.... I spent about $800 on failed molds before I got a mold that worked. T_T

The most important thing to remember is: DON'T RUSH
Take a whole day as mold making day, follow the instructions for the material you are using, patiently measure and mix, and make sure your home is dry and warm.

O wow. Ya I feel like 1 part molds would be fairly easy to pull of (no pun intended) I still don't fully understand 2 or 3 parts as far as keeping leakage at a minimum so more research will be done before that's ever attempted. I feel like as a person who doesn't build suits for a living or business it might be financially a better idea for me to just order parts from someone who has Thank you so much for the reply and info!

To avoid leakages it's good to have a box or fiberglass jacket that encases the silicone (this is also for structure, since silicone is wobbly and flexible). No matter how tight your mold is sealed, leakages will most likely occur

I'm grateful for how much you share about your process. It makes suiting better for everyone! Thank you!!

much better way of doing it than the moose mascot I wore it had a metal pin with a magnet on the end that slotted into a plastic sleeve int the antler...would have worked better but the magnets were cheapo ones and lost their ...charge? after a while This solves that problem
