Alternative filling material

[WM6]

To get more stronger and lite epoxy filling, you ca use vermiculite (construction or gardening additive)..

Are you sure? Vermiculite is a mineral.

Vermiculite loves water. You would have to insure it was Dry first.

I just finished my first coil with Max MCR black A/B https://theepoxyexperts.com/product-...-mcr-black-ab/ For the price it's almost unbeatable. I can fill 5 or 6 large shells with a 48 Oz bottle and it sets hard as nails.. and at least 5x cheaper than MG chemicals 832b ☺.

Looking good Don! how it perform the epoxy?

Hey Don, figured you might like that epoxy, so easy to work with, can be messy as its so thin. I have been using it for several years now. Nice thing about the epoxy is "No air Bubbles".
Now the filler material in the black epoxy will need to be stirred back into solution. Other thing I do, before mixing the hardener, is fill a bucket up about 5" with hot water, set the epoxy bottle in it for about 10 minutes or so, especially if it was stored in a cold area or has thickened too much. You can't beat the price. And there is virtually no odor and the slight odor it has is not offensive.

Do you install the bottom coil form or just leave the potting as the coil bottom?

[dfbowers]

I just fill 1/2 shells (top part only),and leave the potting compound as the bottom.

I fill mix of wood dust+super glue+resin on top layer, very light

The shells I filled seemes to still be working just fine. Anyone ever try a graphite filler for shielding? I read elsewhere that a 13% graphite mix by weight might work for electrostatic shielding.

I have had success using a mixture of sanding sealer and plastafilla(cellulose based). It's very cheap and most importantly it's waterproof and light. Then I use truck bed liner to coat the surface for extra toughness.
