From [http://www.weldingtipsandtricks.com/tig-welding-supplies.html WeldingTipsandTricks]
stuck with 2% thoriated for a long time. It worked great ... but on A/C the tip kind of got jacked up at high amperage. I tried 1.5% and 2% lanthanated and learned that both work fine but the 2% lanthanated works great and even better on A/C. And For TIG inverters like the Miller Dynasty 200dx or the Lincoln Invertec v205t, it is Da shizz.
 
It holds up really well at high frequencies like 120-150 HZ.It stays sharp on DC too.
 
'''The only drawback is that is does not break easily...you have to cut it with a grinder.''' Duly noted. Thought I was doing something wrong by having to grind-cut the lanthanted but guess that's standard practice.

Hablab Cleaning! Jacob is coming.
 
Make [[Terminal Case]]... Needs argon gas refill, new ceramic cups. Make a light tack weld. Then, starting from 1 end (but give enough space for the other aluminum walls), get a junction puddle (between baseplate and wall) then travel along junction edge. Filler adding technique is to insert the filler rod at the junction edge coming from the opposing direction as the weld. Keep the weld small and tight. If for some reason the weld turns big, skip it and do the junction puddle + edge travel again. You can grind off the big part and reweld the gap later.
 
When balling the tungsten before welding, set material-to-tungsten electron % higher and the current lower instead of just increasing the current. This will keep the copper plate cooler while still heating-balling the tungsten correctly. Make sure that the end of the tungsten is a ball.

Ordering Coconut Oil... done Haha! This will be fun! You can eat it, you can machine with it!
 
Safety and health is incredibly important at the minor level because hazards that take off years off your life are actually cutting, say, 5 years of living in *the future*, at which point you can be doing things x10000%+ higher quality and faster than you are doing now. Furthermore, you would be missing out on 5 years of health and safety innovation in *the future* which could further extend longetivity and ability by orders of magnitude more. Critical stuff. Don't miss out. Safety and health gives you a lot more than you might realize, and you don't notice that you haven't been seriously injured so it doesn't enter your mind that much. Chronically underestimated factor of life...

[[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.
