JAG 17, JAG02

I really need that iPhone, you know?

The last two nights I’ve gone to TechShop without a definite plan but left with two waterjet cut frame parts (JAG17 and JAG02… the “JAG” stands for the blueprint part number “James A Greene” designed).

I was messing around getting the part .dwg files exported from the completed Inventor model and then threw them into FlowPath (the waterjet pathing software). Well, I figured, I might as well take the parts back and run a (free) dryrun to see if this worked. Sure enough, they did! The part ran without a problem.

So I was standing logged in to the FlowJet with my 1/4″ plate of aluminum in my truck and I thought oh, what the heck. I got the plate, fastened it down, held my breath, and hit CUT. A few minutes late a perfectly WaterJet cut part emerged from the metal! The first one I cut last night was really easy– basically a rectangle with eight holes cut. Tonight’s part was the much more difficult “Ring 2” from R2’s body. It has 28 holes and a very distinctive “C” shape. I took calipers to it afterwards and confirmed that the cut is perfect! So far so good.

So in the last week I’ve milled up 24 rods (various lengths, 3/4″ diameter) and 4 very precise bars. I still have to tap and drill all these parts, which terrifies me since I’ll be remaking them if I break a tap. But onward we go!

I have 2 more main body rings to cut on the WaterJet and then two much thicker side pieces. Then I’ll be spending a lot of time at the mill edgefinding, drilling, tapping, etc. Tonight I got a master class from a member on lathe tool selection. There’s just so much to know. Cool tidbit: the guy I learned from helped Steve Jobs design the first iPod. He was also on the team that made the Starship Enterprise fly under early CNC control for the first Star Trek movies. An electronics genius. It’s amazing what kind of resources and people are at TechShop.

I’m building props for Sing the next few days so, ironically, I won’t be going in to to TechShop. Nope, I’ll be out in the cold and rain trying to stay dry. Cool stuff building, though. Next week I’ll be back at T.S. doing some more W.J. cutting.

Oh, and the dome (one of the few pieces I bought) should be arriving soon. Hooray!

Edward Snowden: The Untold Story

Absolutely worth the read:

Edward Snowden: The Untold Story | WIRED: “Snowden and his colleagues had discussed the routine deception around the breadth of the NSA’s spying many times, so it wasn’t surprising to him when they had little reaction to Clapper’s testimony. ‘It was more of just acceptance,’ he says, calling it ‘the banality of evil’—a reference to Hannah Arendt’s study of bureaucrats in Nazi Germany.

‘It’s like the boiling frog,’ Snowden tells me. ‘You get exposed to a little bit of evil, a little bit of rule-breaking, a little bit of dishonesty, a little bit of deceptiveness, a little bit of disservice to the public interest, and you can brush it off, you can come to justify it. But if you do that, it creates a slippery slope that just increases over time, and by the time you’ve been in 15 years, 20 years, 25 years, you’ve seen it all and it doesn’t shock you. And so you see it as normal. And that’s the problem, that’s what the Clapper event was all about. He saw deceiving the American people as what he does, as his job, as something completely ordinary. And he was right that he wouldn’t be punished for it, because he was revealed as having lied under oath and he didn’t even get a slap on the wrist for it. It says a lot about the system and a lot about our leaders.’ Snowden decided it was time to hop out of the water before he too was boiled alive.”

The rest of this excellent interview details even more appalling behavior that the secret organizations commit.

People say Snowden betrayed his oath to his country. I believe it’s more like he betrayed his oath to the government, and the government is the one that betrayed the country. Betraying his oath to a betrayer is simply proof that he’s back on the right side.

I’m pretty much coming to the conclusion that I’m glad he did what he did.
