making a mold from live bait

Recommended Posts

I Was Wondering If Any Tu Members Have Tryed To Make A Mold From Live Bait That Is Now Dead. I Now Have The Little Guy Froze But Wondered What To Do To Prep Him To Make A Mold From Him. I Have Already Made Many Molds But Never Tryed This? Thanks Again To All The Tu Members For All The Advice. Anthony Trenshaw

Don't quote me on this, but I think Alsworms made a two piece mold out of a bullfrog.

Unfortunately, no. Mine were made by Charlie too. I spoke with him during the summer about making some more, but he's completely out of the business now. Who knows though.......he might be starting to get that "itch" again. Couldn't hurt to ask him.

BTW......great guy. I'm sure he would help if he can.

I've been messing about with alginate, doing face casts for another project during the last few weeks. It may well be a good solution to this problem.

Alginate starts off as a powder, similar to PoP. Add water to make a thick paste and apply to the fish, all over. It goes off very quickly, under 3 mins, so you have to work quick.

Once it is set, it is a very soft rubbery material. If you are making a mould of a larger fish, you may have to reinforce the alginate jacket with modrock (a PoP impregnated cloth).

With a sharp knife, split the jacket down the middle and remove the fish. Close the split and seal, with modrock, or wax, or glue etc.

Make a pouring spout at the nose and fill with plaster.

This will give you a plaster master. Once the plaster is fully dried (oven), any seams or faults can be sanded away and/or filled. From here you can proceed how ever you want.

Alginate and modrock are readily available in craft shops and are very cheap.

Comming along nicely, learning lots. I have made a few novelty rubber nose door stops for amusement (gelflex), they work great!

I should add that alginate is a 'one shot' medium. It deteriorates after a few hours as it dries out. So, the plaster stage has to be performed in the same work session, not the next day.

I second that, Alginate is water based & doesn't exotherm (heat up while curing) if it does, I cant tell.

You can do the initial (negative) mold in alginate, then cast that (positive) mold with additional alginate (it doesnt stick to itself once cured) then you have a soft master (positive) to cast a rigid (negative) mold using plaster or water putty.

3 steps, but the first 2 can be done in 15 minutes.

If you want a flexible mold (RTV) then substitute the second cast with plaster, then in turn cast that one with RTV, resulting in a flexible negative.

Hope that don't confuse anyone, I almost confused myself. :huh:
