Group clean Hablab!
Pictures for Light Screen, Trencher, Flashlight Mount
Light Screen from Josh missing a few parts - must search in Tristan's car...
CNC Torch Table Steppers' electronics interface wired up.
Set up camera tripod
Terminal Case interface with PCB mount...
Ordering HDPE plate for CNC electronics... done
3/11/2012
Tooling Plate fabrication preparation...
Terminal Case V3 welding... done - TIG welding aluminum isn't TOO hard...
We'll need to recharge our argon canister soon. Medium size canister is easier to transport, but must price check on medium and large refills.
Design, prototype, documentation Thermal Shield for TIG welding... done, done, and done
Preparing for next sweiger trip. Lathe/powercube accessories, iron for tooling plate, metal for stove door, pure argon gas refill... done
Must order edge finder (ex. from mcmaster-carr), but waiting on further items to optimize shipping.
Husking Walnuts!

Hinge redesign for stove
2/11/2012
New stove door design... mostly done.
Ordered aluminum bar for Terminal Case V3 construction (with welded seams for rigidity and waterproofing)
Tested and documented Trencher V1.5 with Aaron. It works pretty good!
Began TIG welding Terminal Case. Started using filler rod for the first time. The aluminum gets HOT. Don't touch it, even with gloves you will get burned. Cannot TIG weld continuously without heat shield. Must design heat shield for hand.
We need more 240VAC extension cords. Must order male and female plugs, as well as more large 3-strand wire.
Ordered 2 bandsaw blades

Stepper Motor considering: bipolar super torque steppers from Lin Engineering (http://www.linengineering.com/LinE/contents/stepmotors/5818.aspx)
Flexible shaft coupling considering: from http://www.mcmaster.com/#standard-shaft-couplings/=jzypil
Plan: organize drill bits
Plan: work on improving flashlight mount - magnetic mounting, adjustable angle
1/11/2012
TIG Welding tests... still no good. Grinded the aluminum and reduced the length of tungsten alloy tip sticking out to 1/8" but instead of puddling properly the aluminum totally melts underneath a film of oxide...
Bandsaw blade ordering [Emailed Parker and Marshall for previous bandsaw blade source]...
Thiel Fellowship monthly review... done
Thiel Fellowship annual update... done
Sweiger trip with Gabi for farmer's bank credit card form, powercube materials and TIG welding troubleshooting... success, success and success.
TIG welding aluminum test... success! Minor change was to mount the tungsten collet in the opposite direction. The major change was to ball the end of the tungsten by applying some high current 150-200A at ~50% AC balance to the tungsten tip but using copper plate.
Prototyped flashlight mount.
