tried air before- is this unit cold enough to keep al from sticking in end mills w/o solvent? --.with advent of the toothed roughers for al hasn't been quite the problem if I don't get in to big a hurry..russ

It will get cold enough to form heavy frost on the Loc-line tubing if the shop is humid. Won't work great on heavy cuts in gummy aluminum.

I read that hexapod machines were being developed about 5 years ago, hadn't envisioned that they would be generating a Z-axis. (up & down for you non-machinist types). Wonder how rigid that system will be.

Speaking of Marlo, Desotos, and CNCing, Marlo found a faster way to do machine work, by having a FBI plane stick its spinning propellor thru the side of his Lamborghini while driving.  I believe the Lambo engine (complete with Desoto script on the valve covers) is intact, so if you need a spare, drop him a line.  How's that for comma's Slim?

Bob,
  I am glad Marlo did not get hurt in that incident. Too close for comfort.

Tortoise, ah shit,...........................

Pretty good, Bob, although it would have been better if you had substituted an ellipsis for the fourth comma.  And Tortoise already got you on the apostrophe, so I needn't do anything.  Thanks for asking -- and thanks for trying.  You get an A- for the post.

An A from SSS is like calling your mother from the induction center to tell her you got the job.

Mr. Back, Sir, I humbly ask if you'd like to take over.  I got so focused on spelling and punctuation that I overlooked the capitalisation error.

Oh, the shame of it all.  I think I'll go hide in the little green room and lock myself in.

Since you arrogate unto yourself the role of teacher, you are held to a higher standard. We rightly expect of you not only impeccable spelling, grammar and punctuation, but elegant style.

"I got so focused . . ." will not do.

"Capitalisation" with an S rather than a Z is more common in British than American usage, while "focussed' is the more usual British spelling.

Aircap, the hexapod concept has been around for a long time and actually originated from motion bases used for flight simulators. Giddings and Lewis did some of the first application of the concept to machine tools and as I understand the rigidity is very high certainly equal to a sliding axis machine.

Watched the 5 axis milling of the engine block and was impressed on the finish cuts for the cylinders, must have had a ball end mill and then did a 5 axis move to make the cylinders round. Very interesting. I worked on several very large 5 axis conversions when I was at Standard Tool and Die, we did 3 large Lucas horizontal boring machines that we added a French built 5 axis head. Worked well.

Coolants: While at Standard Tool and Die we did some interesting stuff with titanium. We were doing a job for Lockheed and needed to hog out big slots in some ti bar. We used liquid nitrogen for coolant. Literally made the stuff cut like aluminum. When the liquid nitrogen bottle would run out and the flow stopped the milling cutter would snap, instantaneously!!

Russ Jensen's machining ability. Desoto man you should take Russ up on his offer, I have seen some of the parts he has made very impressive!! He has made some guns that are really unbelievable!! He is very talented.

Arrogate -- to take or claim something for oneself without justification.  Hey, now, I thought I had justified the appellation pretty well, but I'll be glad to apologise and retract if you feel it's a valid point.

As for the double "s" use -- I read a British newspaper (among other things) and haven't seen enough usage of that double "s" to have chosen to integrate it into my lexicon, but I assure you that I'll be more observant in the future.  The only dictionary I've got here (at the office) shows, by the way, that the spelling "focussed" is an intransitive verb.  The phrase "I got so focused" doesn't use the f-word as a verb, so single "s" seems correct.

. . . I'll be glad to apologise . . .

You have taken the moral high ground, which trumps all. (I slink off the field.)
