That was helpful. I think I will get a few EMI filters for the Opto boards and signal power supplies. Thanks Kirk! Tom Please don't spend your money just because of my comment, just keep it in mind if problems come about. Because VFD's use higher frequency switching, at decent currents, they can create noise on the mains input or other places, but before you spend money, get a second opinion from others on this list, who may have better advise. Another experience I learned from was, with the original motor lead filters on my Hardinge lathe, when I added the VFD, the filters overheated, melted and smoked. Apparently, they tried to do their job of filtering out high frequencies, which VFD's normally put out allot of. The ferrite beads didn't seem have that problem. But I learned this from trial and error rather than informed design, which is not the best way to do things connected with high voltages, currents, mass, dollars, etc. - Kirk http://www.wallacecompany.com/machine_shop/ -- SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.

[Emc-users] My campus server don't support the Linux system logging Internet , and I need to revise the kinematics module's inverse tranformation
Dear Sir My campus server don't support the Linux system logging Internet , and I need to revise the kinematics module's inverse tranformation, you know it's necessary to log in the web to configure the relative document, like installing CVS program. So, I want to know, whether I could download the relative document to the flash disk, and then upload it to my Linux opertaion system to finish the configuration process. If I can't do it through this, would you please give me some other suggestions? Your support will be highly appreciated!

Never mind. Thanks. Kirk The red line is the boundary. I'm posting a side view of the tool paths rather than isometric as I think it illustrated the tool paths better. green = .500 SE rougher at 0.1 offset in z red = 0.500 ball end mill at 0.0 offset in z 1770 guns hardly count as an instrument of destruction; more like meat, shoes, and protection. Those were not nice times to live in. This will end up on a short barreled muzzleloader more like the jaeger the german immigrants brought with them but without the european style stock which is/was much less graceful than those of the American made guns. I have thoughts about getting a blog going and if so the instructions for getting the correct contour will be there.

When I saw the images I had a feeling it was for some style of musket-loading pistol - very cool. Nice work and glad to see Synergy is working well for you. Definitely start a blog of you work. Replica work like this, though not the historically correct method used for the originals is very cool and I for one would love to follow your work. Personally I'd like to get around to making up my own AR-15 receiver with some flair (within the legal limits of personal use and not for sale - just being clear so as not to get anyone's knickers in knots). Granted not as historical as a musket but firearms are still a passion of mine regardless of the genre. Of course since I finally had a legitimate way to bring up firearms and EMC I now have the opportunity to tell Gene that I love the Ed Howdershelt quote in the sig line :) Personally I've only used defenses one and two thus far, someday (I'm a young'n in my mid-30s - lots of living left to do - I hope) maybe I'll be called upon for number three but I sincerely pray I never need to use four, especially for defense of freedom.

I got a letter for petit jury duty a couple of years ago, and was amazed that I was excused because of my age after I filled out the form and returned it. Darnit, I have more spare time than some poor schmuck who has to take a week off from work, losing several hundred dollars in income he probably sorely needs, and I think I can listen to the arguments as well as the next person (if they speak up that is, my hearing had been damaged by my hobbies). And I'm far more likely to consider jury nullification if the charges appear to be trumped up than some youngster with far less of lifes experience to judge things by. But I got the impression from reading between the lines that what they wanted were robots the judge could program than real, reasoning jurors. but I sincerely pray I never need to use four, especially for defense of freedom. Greg FWIW Greg, we have at least 200k men doing that right now, in Iraq and Afganistan amoung other places. But I don't for a minute believe that is what that particular quote meant when Ed wrote it. Much more along the lines of a rather famous half quote of Thomas Jefferson: The tree of liberty must be refreshed with the blood of patriots and tyrants from time to time, and the rest of that comma terminated quote is and God help us if we go 20 years without it. which does not get the well deserved ink the first half seems to get for free. That to me, is what the 2nd amendment is all about. The ability of the people to defend themselves from a government run amuck, is how I interpret the last box's meaning. Sorry about the rant folks, but no one who attacks the Bill of Rights ever gets a 2nd vote from me...
