Modifying The Hook Collar With High Temp Silicone

Recommended Posts

I recently did this reversible mold modification and thought that it may be of use to others.

I used high temp. silicone to create a dam so the lead would not fill the collar area of a Do-it Poison tail mold.

 

I also filed in a groove on either side of the hook shank to allow a straight piece of stainless wire to lay when the mold is closed

Later, after the head is molded, the wire will be bent to create a hook keeper

 

On this mold, the first step was to create the channels next to the hook shank for the wire to lay when the mold is closed.

I used a round, fine tooth file.

The diameter of the portion of the file was approx. 3/16" (tapered file)

Carefully remove the corners but do not deepen the shank channel (see pic below)

I actually needed the aid of an magnifying glass to see what I was doing.

You get a good view of the wire channel next to the hook shank in this pic

I then poured some dummy heads, minus the hooks.

I cut and filed the collar off, but left the sprue on to act as a handle to remove the head.

I degreased the mold collar area with solvent to assure good adhesion of the silicone

 

I then used petroleum jelly on the dummy head to prevent the silicone from sticking to it and set them in the mold

I overfilled the collar area on half the mold and let it dry overnight

The next day, I carefully removed the dummy heads, used them on the other half and filled the other side of the mold and allowed that side to completely dry.

 

Making sure that the silicone has reached full hardness, you will need a sharp razor blade (new is good) to trim the silicone flush.

That's about it!

You're ready to start using your mold

great job, Scott. Works like a champ. BTW, what is that High Temp Silicone product?

Thanks Mike. Glad to hear that it is working good for you!

This mod could work out for making those "ned rig" heads to mold them without the collars and maybe a wire keeper. 

 

The product that I used is "Permatex High-Temp Red RTV Silicone Gasket" 

Widely availible at most auto parts stores

Nice mod. Thanks for sharing it. The wire keeper's great.

Thank you Apdriver

I do appreciate the info and willingness to help one another here

I've learned a lot from visiting and reading all the questions and answers given.

:yay:

Nice info....I use the blue and white putty to modify my molds. It sets up in 10 minutes.

If you don't mind me asking, what is this blue and white putty you speak of?

Does it stand up to the high temperatures of molten lead?

Dries rock hard?

I'm envisioning an epoxy stick that you slice a piece off and knead it to mix the two layers
