So, if I understood it well, you made 2 attempts with male and female silicone mold, with the female mold being boxed, and the second run was not as good as the first one? Any idea of what was wrong ?

Anyway, cant wait to see it with the twill. Good luck and keep us updated

Yes that's correct.

The problem I'm having is that the back of the cover isn't a consistant thickness. In the very centre I'm getting 0.46mm and as it gets closer to the corners it gets up to 0.7mm. Also I'm getting little bubbles and voids in the corners.

I'm going to cut the sides off the two failed covers and use the backs as shims to hopefully equal out the pressure when I clamp it. My theory is that the silicone is expanding more in the middle than on the sides.

I'm just finishing my press now with proper nuts and bolts. I was using a billion g-clamps and vice grips previously. I hope to make another cover soon.



There's the press-o-matic 3000. I'm going to put the shims in between the beige plug and the top plate.

Hey, Adam.

Your setup looks nice and clean, i hope that with proper nuts and bolts it will be fine.

As your description suggests it (different thicknesses), your tiny bubbles and voids would be caused by a lack of pressure on the sides, so hopefully its "only" a mechanical problem... Guess the shims would help here.

Keep on refining and show what DIY'ers can do

Cheers from Belgium.
