Moving the build thead if anyone would like to attempt it.
I'm building this from scratch so I dont forget to add any of the steps.
Just like the stone with the checkerboard pattern from one of your pic is a hematite path,
If you grind down into the raised area you would find the line of fused
hematite within a non-conductive casing. This will be the starting point of the build.
The few things that are needed.
1/4" paperback foam hobby board.
spray glue
fireplace type mortar "non metallic"
small paint brushs
band saw or razor knife
1/2" foam sheet 8x8"
8"x8"x 1" or so granite slab
Print 2 copys of this pattern. spray glue them to the foam board.
cut and remove the gap area and glue the parts to the 1/2" sheet foam in uniform. (1)
use a paint brush and add 5 layers of mortar or 1/4" high around the edge of each part.(2)
let each coat dry under a light bulb 10 minutes before the next layer.(4)
drill holes in all the open areas to help the parts dry after the pattern is
placed upside down on the granite slab to dry (3)
on layer 6 have the clean flat granite type stone ready for the wet pattern and place wet mortar side down on the granite gently (5)
leave the other pattern under the light bulb.
I use an old toster oven to heat the granite a bit at a time. dont overheat anything or it will add small holes within the mortar.
walk away for 12 hours, done for now.
Its much easier to remove the foam from the parts then most other plugs made of plastic or wood for testing.
Need a few more things at this point
Carbon block- brushes from a drill.
1/8" copper wire 1/8"
iron hematite crytal dust.
Use carbon dust and mortar to make continuity like wires in the unit.(1)
Add the copper/ nickel bronze welding wire in the 7 holes leaving 2" out the bottom.
seal them all with the carbon mix mortar and overlay the raised portion next to them, fill the star 1/2 way (3)
build a 6 finger star, cut three of the fingers 1/2 way up so the star will nest.fill the star 1/2 way with carbon mix mortar(3)(5)
start a new design from waiting....(4)
