Considering Rocky Mountain Lodge in Horseshoe Bend, ID?

The pictures on various websites are beautifully lush, but these show only the immediate house location.  Surrounding hills (which are all privately owned and not generally open to the public) look like this:



And yes, it is as dry and tinder-like as it looks..We sometimes get very impressive brush fires, like this in 2012.  And yes, it closed the only road to Rocky Mountain Lodge.




You also get to enjot the cultural diversity that rural Idaho is known for worldwide:

Teaching myself gCode

This a is low level CNC control language. Roughly similar to teaching yourself assembly language so that more fully understood what the C compiler is doing when you write a Hello, World program.

UPDATE:  Not as bad as writing PostScript, and the LinuxCNC paxckage has a nice simulator for  testing while waiting for stepper motors to arrive.

Stepper motors arrived.  But the mill is sitting on the kitchen table during a church board meeting, so I am still writing gCode.  Fortunately, this part involves only a few right angle mill operations, so it is only laborious to write the gCode.It's a bit more laborious perhaps than it needs to be because I am only taking off .01" on each pass, because I am sure that the cutters and mill can take off that much aluminum with no hiccups.  I might experiment at some point with .05" per pass.

Unfortunately, while the x- and y-axes wre doing their robotic thing perfectly, the z-axis was behaving oddly, and even manually refused to rise.  This kit came with three handwheels to attach to the far end of the stepper motor shafts, allowing m,anual use as well.  There were two sizes, and it weasn't clear which axis the larger handwheel was for.  The attachment mechanism and shafts were identical, but the fact that the small handwheel will  not come off the Z-axis suggests that there is something special about this, and it may have damaged the z-axis motor.  Of course, Sherline is closed for the 4th weekend, so I will have to wait until Monday to resolve this.  In the meantime, resume gCode development!

This is what it looks like:

Maine About To Go Constituional Carry

Here's the bill.
Be it enacted by the People of the State of Maine as follows:
Sec. 1. 12 MRSA §11212, sub-§1, ¶B,  as amended by PL 2005, c. 477, §9, is further amended to read:
B. A person may not, while in or on a motor vehicle or in or on a trailer or other type of vehicle being hauled by a motor vehicle, have a cocked and armed crossbow or a firearm with a cartridge or shell in the chamber or in an attached magazine, clip or cylinder or a muzzle-loading firearm charged with powder, lead and a primed ignition device or mechanism, except that a person who has a valid Maine permit to carry a concealed weapon is not otherwise prohibited from possessing a firearm may have in or on a motor vehicle or trailer or other type of vehicle a loaded pistol or revolver covered by that permit.
Sec. 2. 25 MRSA §2001-A, sub-§2, ¶A-1  is enacted to read:
A-1 A handgun carried by a person who is not otherwise prohibited from carrying a firearm;

The governor is expected to sign it.  One less state I need to renew a permit for.

My CNC Mill Arrived

I still need the stepper motors and the interface box, but those are in transit.  It is very nice to have a brand new mill, instead of upgrading my 23 year old antique.

An Interesting Conflict Within The Coalition

Breitbart reports:
Chicago’s 47th annual gay pride parade was disrupted several times by the usual city disruptions — gang activity, gunshots, and drunks — but the event was also disrupted by a car driving into a group of bystanders. Then there was an even larger interruption by “black lives matter” protesters....

But by far the biggest disruption was from a large group of “black lives matter” protesters. The group was joined by members of the black queer community of Chicago who announced the disruption on their website.

After noting that they had “purposefully disrupted the Chicago Pride Parade,” the queer group explained their reasoning.

“We do so,” the group said, “because our people are dying at the hands of police, military and state-funded militias around the globe. We do so because we refuse to be tokenized by the same corporations that sponsor state violence, refuse a living wage and profit off our poverty. We do so because young queer people need a better outlet to celebrate themselves than a mire of consumption and sexual violence.”

The queer group was also attacked by the “black lives matter” protesters who held signs and walked as a group to push their own message.
 Corporations have indeed backed gay pride as a way to sell beer and tobacco (because substance abuse is a big problem in the gay community) so it's nice to see the different factions of the progressive community coming to argue.

There Goes the Brady Center

A while back, the Brady Center filed suit against Lucky Gunner and everyone else who had sold anything to the theater shooter in Aurora, but because the suit violated both federal and state Colorado law (you can't sue if the gun or ammo works as advertised, short of negligence) the judge ordered the plaintiffs, the parents of a murder victim, to pay defendant's legal fees.  The question is who would get stuck with the huge bill?  The parents or the Brady Center?  
A federal judge has ordered that the Brady Center to Prevent Gun Violence pay the legal fees of an online ammunition dealer it sued for the Aurora movie theater shooting.

The order, which was issued last week, comes after Judge Richard P. Matsch dismissed the gun control group's suit that sought to hold Lucky Gunner legally responsible for the 2012 shooting. The Brady Center had argued in their suit that the way Lucky Gunner sells ammunition is "unreasonably dangerous and create a public nuisance."

"A crazed, homicidal killer should not be able to amass a military arsenal, without showing his face or answering a single question, with the simple click of a mouse," Brady Center's Legal Action Project Director Jonathan Lowy said at the time. "If businesses choose to sell military-grade equipment online, they must screen purchasers to prevent arming people like James Holmes."

Judge Matsch disagreed with the Brady Center's argument. He said the suit was filed for propaganda purposes. "It is apparent that this case was filed to pursue the political purposes of the Brady Center and, given the failure to present any cognizable legal claim, bringing these defendants into the Colorado court where the prosecution of James Holmes was proceeding appears to be more of an opportunity to propagandize the public and stigmatize the defendants than to obtain a court order," he said in his order.
