    I know that, I'm just wondering what causes it. I also haven't heard a reasonable explanation why a drill bit will tend to cut a hole with one more side than the number of cutting edges. I've been told this property is why reamers can have an offset blade to help cutting a more perfect circle.

    I don’t understand what you mean?

    Those are the metalworking equivalent of crop circles

    The example of the saw cut rod is an effect of the wave set of the saw blade. As the wave in the lower edge of the blade enters the cut, it forces the blade to the other side of the cut and produces the ripples in the work-piece.

    The problem with drills and reamers is that of the Reuleaux Polygon whereby, if one flute of the drill/reamer sticks, the other flute/s can keep on moving and cut a polygon with one more faces than the number of flutes. once this has started, the process tends to carry on.

    Ah..thank you sir. The Reuleaux Polygon was the answer I was looking for. The saw pattern still intrigues me because of the increase and decrease in the width of the nodes as the blade progresses downward, the appearance of superimposed circles and the interference pattern they create. I'll have to think about the action of the kerf wave for a bit to fully get this. Thanks again.

    Finally finished the b-ball standard for me and family (read: kids)!

    One thing I noticed: I don't weld often enough.

    [IMG]IMG_9364 by crh2765, on Flickr[/IMG]

    17-4 main shafts machined 12'-2" long, 3/4-16 outside thread and 1/8-27 inside for the zerks. Smaller ones hold the jack, etc. That 17-4 sure machines/threads nicely. Couple that stainless with fine thread & nyloc nuts and it galls nicely also!

    You didn't heat treat it did ya???


    This weeks fun..

    This is something I've wanted to make for about 10 years now.. I can't
    be the only one that uses their vises to hold fixtures, or other work
    holding devices, or even stops for the next vise over.. And you
    open the door and the first thing you do is instinctively open the
    vise, which is fine.. Unless opening the vise screws up your whole
    setup and sets you back...

    If I remember, I usually put a c-clamp or can't twist on the vise screw
    so I can't put a handle on it.. But, that's not very cool. So I finally
    made some of these.. 10 years thinking about it, and it took about an hour.




    And if you go back 30 posts or so, I was playing around with kokopellis to
    put into some gates I'm making.. And then the brains started moving around,
    and I was looking at some other stuff.. And I decided that playing with
    heat and texture would be fun..

    So.. This is what I came up with.. I've never done the heat and texture
    thing before.. I'm not really very artistic.. I can occasionally be
    creative, but I'm really happy with how this turned out.. I think I'm
    going to do the entire gates like this and have them powdered clear.

    The first pic is just a pic. I think its neat.. Some of you may not..
    But the second pic... Is the EXACT same thing (if its "artsy" is it a "Piece",
    not just a "thing"?) Just outside in the sun light.

    Weird observation. Painting, to make the paint shiny, the metal has to be
    baby ass smooth.. If its all roughed up with 60 grit, its going to look like...
    Bad.. Really Bad...

    This heat to color stuff.. The smoother the metal is, the duller it is. The
    outer oval, I did with one of those nylon abrasive discs. DULL... Which is
    fine, I was going for browns, maybe a woodish looking thing.. But the kokopeli
    itself. 60 grit flap disc, it SHINES.. The way the light dances off of it
    is really neat...

    That STOP is a great idea.

    Like the "stops" Bob...............

    I'm not quite as creative...................I use a hose clamp to keep from opening the vise or to keep a wrench on the hex.......................

    Car:

    I'm not following the mechanics of that unit.
    Maybe if I could see it bigger ...

    But you have two items on the same side of the pivot point.
    Shirley one of them is a cyl, maybe the other is an adjustable stop?

    Air or Hydro?
    Plumbed from the shop I ass_u_me?
    (or will be soon)

    Glad to see that you used your abilities to be able to make something on the cheap!
