Wire Weaving ProgressI need to rustle up some cash before I send my inventory of woven slabs to the coater. Meanwhile, I have developed a method
for maintaining the shiny color long enough to get them all polished at the same time without some of them oxidizing. The
shiniest of copper is more of a pink color than orange, but in room air the color changes within five minutes. I can keep
them under cold clear water indefinitely. I still need to figure a way to get them dried off without oxidizing, then stored
at a coater until coating. I plan on a quick blow off with an air hose, then into an argon purged plastic food storage container
containing an activated dessicant. I have a few pounds left over from a flower drying kit. It has been a year now since I
made the first weaving, and it will be few more months before I have an inventory of one each of the items I want to sell.
There will be five sizes of squares and five sizes of rectangles. The smallest will be two inches square, the largest 12x12
or 9x15. The items will be priced by the square inch. The price per square inch will float with the Comex. Right now 1-30-10
grade A copper for delivery next month in 25 ton quantities is selling on the London Metals Exchange at $3.046/lb. Take
half of that and add to $4.50 and you have the price per square inch. Round down to the nearest tenth of a dollar. Right now
the 2 AWG Dutch weave mesh would sell for $6 a square inch FOB Fred's. This is signed and delivered Priority Mail. If you
pick up at Fred's you can get your pocket knife sharpened. Don't forget, spring is just around the corner. My annual spring
time gang fight special is starting. Bring in two stillettos - third one free. Also free motorcycle chain sharpening with
each spiked ball and chain.

The Failure of Diamond SegmentsI cannot cast diamond segments at the 10% diamond by weight level without producing a sintered like, friable, non-wettable
mass. All of my castings are highly crystalized. 308 Stainless steel solidifies to a mass of needle like crystals. When hammered
or bent it crumbles. Once made, they cannot be wetted with the brazing rods and fluxes I have. I have given up and returned
the drill.
