DIY Holster Form/Dummy Gun

[OnionsAndDragons]

Rich,
I've had decent results making mold shells for casting out of 0.093 kydex. That thickness seems to produce excellent internal definition. I just cook it longer in my heat press, since I'm not worried about glossing it.

Best results from using a membrane free vac former, but it works fine in a standard vac press too.

I've tried AdTech F100 resin, and the alumilite vac 25. They both produce good drones. I found the F100 a bit easier to modify or machine afterward.

O&D,

Thanks for the info!

The .060 HIP polystyrene is working well and is about 1/4 the cost of .093 Kydex. The .060 thickness is plenty rigid for forms as small as most hand guns.

I cant find the Adtech F100 resin listed anywhere. Is there another industry name for it? Adtech's web site lists about 20 different epoxy resins but no F100.

The Alumilite Vac-Master 25 has too high a shrink rate and is bit more viscous than I like. I have used it for other projects in the past.

I settled on Freeman Supply's Repro NS polyurethane resin with their wax paste parting agent.

After some refinements to my vacuum table and dialing in the process, I'm getting great results.

Sig P225 fresh from the mold.





very little mold flash to clean up.

How's this stuff compared to what Ring's molds with?

It's a good bit harder and heavier. Less scratch resistant but not flexible at all.

It's similar to DIY's medium, maybe a bit less brittle.

Noice!

The F-100 I've used, I purchased through Bill of Redfeather Gear. He makes some really high quality drones and makes materials available to try your own hand at it. He has a background in mold making for set design and other stuff and was super helpful.

I mostly just hated dealing with the poly sheeting. I don't have a kitchen sized oven in my shop and use a tshirt press for most of my heating, so using kydex just made more sense for me.

I'm guessing the stuff you are using now is similar to the F-100. It's poly based with a glass/silicate filler.

This pleases me immensely.

O&D,
Freeman Supply assured me it's not glass filled. The glass filler's are very hard on cutting tools. Probably aluminum filled but I can't swear to that. It does cut and shape easily quickly out of the mold.

This pleases me immensely.

I can send you a left over puck from the mixing tub if you want to test it. Text or PM me your shipping info.

I have to correct my earlier statement. The Repro NS is glass sphere filled. I must have been remembering a conversation about one of the other products I tried from them.
