Milling a PCB without clamps Piccola CNC's vacuum table holds copper clad flat by suction — a rubber cord sets the vacuum area, and the included pump is quiet and can run indefinitely. No clamps means the whole board is usable edge to edge, with nothing to route around. Combined with height mapping and centre finding, it makes double-sided PCB work straightforward rather than fiddly. Best with a 2mm MDF sacrificial layer. Available as an accessory. #CNC #PCBMilling #OpenSourceHardware

Clearing roadblocks in the way of firing up a color furnace. I am consulting with Mike, who melts color at a big public glass studio in Brooklyn in Gowanus, and for another factory in West Virginia. I know I want a dark, ambery brown. We are going to get 100 pounds of Sprucr Pine "color base" - all the raw ingredients for the HotShop glass- minus the decolorants. We plan on using some of sulfur, black charcoal, and sugar along with a touch of black nickel to darken it up along with a few other things to tint it. I CNDd a thick scrap of MDF to make a lid for the cement mixer- which Mike mentioned is one of the best ways to mix it up- essential for proper glass. I also cleaned it from refractory cement with hammer, chisel and power washer. The furnace burner still needs to get its gas/air ratio set with a test firing, and I gotta find a time to rent 2 workstations (it's in the corner between them) #color #glass #residency #mixing #colorpot #neon #CNC #nonprofit #sculpture
