    When drilling (or punching) a series of holes in a row for lightning, appearance or some other non-structural reason, is there a rule of thumb for spacing the holes, such as a space equal to the radius between holes (1 inch holes, 1.5 inch on center), diameter (1 inch holes, 2 inch center), or is it just what looks right?

    Google that
     
  3. Thanks 31vic! I learned something today!

    Ask an older guy. They don't teach math in school any more...

    Hmm, the 1.5 looks a little tight, and the 1.75 a bit far. Maybe there is something to that 1.6 golden ratio. Thanks guys.

    I realized I had some 1 inch diameter sticky dots so I placed those where I want the holes, to let some air out of under my visor. I have a bad habit of doing stuff I later regret so the 'measure twice' theory is always in place, even though it doesn't always work. I think I may be slightly 'over golden'.

  8. Ya think ?


    The golden ratio has fascinated Western intellectuals of diverse interests for at least 2,400 years. :)

    Hole size to available edge distance too !!!

    Ah intellectuals, that's why I never heard of it.

    Yes, 1 inch too close to my edges. Prolly go 3/4. Thanks.

    I wonder if small holes like that will whistle. I would think at some speed they would.

    Looks...all about how it looks.
    That's why I did this exercise on my bones.

    I see this relationship, but what about holes of different sizes like progressively smaller holes in a tapered frame rail or bones? How to space them from the edges and from each other.


    Fascinating!

    On a taper, I try to maintain the same "edge clearance" and hole spacing. That taper dictates hole size.

    I always do odd numbers. I had a photography professor back in the day, amazing man, mentor, great inspiration, and Nazi death-camp survivor, who taught me everything about composition. He suggested that the human mind finds odd-numbered quan***ies more pleasing. Not sure if that's true, but it has always worked for me.

    I miss that guy.

    7-holes in the A-bones, 17-holes in the A-beam, on my '29A.

    My wife tipped me off to the odd number of holes thing.

    That did not come out right!

    "Beauty is in the eye of the beholder"- You'll probably look at it more than anyone else, and if you think it's wrong, every time you look at your car it's the first thing you'll see. lay it out a few different ways, find one you like, and GO FOR IT. I believe every car should be different; .If you don't like something, change it. (or build another one!) BTW-I use the "One, two, three, O'Leary" method. Mike from M***. Actually, the car in my avatar was done with the "Eeny, meeny, miney, moe" method- left side is off 1/8 inch and I see it every friggin' time I go in the garage( maybe I'll turn the car around? Hmmmmm)

    Must have!! Searched for cipherin gozinta, came up empty.

    A really slick one of those would have the golden ratio built in.

    I do believe that cipherin' tool is a sewing tool. I have one I found in a box lot of sewing items. Picked it out because it was cool...and handy.:)

    that tool can be made "on the cheap" by using stretch sewing band. that you lay out [without stretching], mark a uniform set of marks [every half inch for instance], when stretched the marks stay uniform.

    Sewing tools come in handy. I have a sewing measuring tape I keep in the garage. Its flexible so you can lay it on curves for measuring stuff. Also use another trick I learned from the sewing/upholstery industry for equally spacing something between two known points without using any of that fancy math stuff.

    I use something very similar, found it in the surplus section at Princess Auto.
    It cost like $3.00 and was marketed as an "Expanding pet gate" or something like that.
    I know it must be for Gerbils or something because a normal dog could walk right over it...but it works awesome for spacing holes!

    Question about cutting this many small holes in thin sheet metal. Is it possible to paint the thin edge of the holes, and will it stick? Have not had this situation in sheet metal but I do a lot of woodwork, and a sharp edge is a not good when it comes to paint.
