You may end up with loose out of round holes in your pursuit to improve a tested design. As an alternative you might consider using spacers or washers to fill the gaps. If you carefully trim a spacer to a snug fit you will be able to tighten your bolt without deflecting the main tabs. Deflecting the tabs would also worsen your situation.

It may very well be fine, probably is, I haven't seen the actual specs for those fasteners.

    Oh come off it. There are hundreds of Kolbs out there and there are even a few Kolbs that have thousands of hours on them with in-flight loads over gross and the has never been even a bent pin (from flight loads). That's not to say there isn't maybe a good idea to put spacers in but.... Also that plane that Dennis folded the wing on was one of the newer kolbs (maybe a MKII). He had to really really work at it to get it to fail. Also they didn't just fix the drag strut and call it good enough!!! They fully inspected the wing. If the attach point pins were bent in any way they would have fixed that also. This wasn't just some required test that they went thru (it isn't required and no one else cared enough to do this). The point was they cared enough make sure it was safe. Just don't go fixing something not broken and make it fail Rick Neilsen Redrive VW powered MKIIIC ----- Original Message ----- From: "Dana Hague" <d-m-hague@comcast.net> Sent: Saturday, April 07, 2007 9:24 AM Subject: Re: Kolb-List: Re: Kolb Wing Attach Points > > At 09:01 AM 4/7/2007, DANIEL WALTER wrote: > >>I believe it was the Ultrastar wing that was tested to failure, I think >>the >>pins in question all surived.

    After watching the list for years and wishing my schedule would allow me to get to MV, plans finally came together this week, and this year looks like the one. It's been frustrating, since I actually live in Utah - but put me on the list of whatever activities there might be. We will be staying in Mexican Hat rather than at Goulding's so reservations are all handled. Doug Wetzel Lurking since 2001

    To All, Just got done building my fuel tank for my Firefly that I pulled from a mold I built last week. I have not drilled and tapped the holes for the fittings yet but the hard points are in place for a pickup in the small sump in the bottom, a vent in the bump on top and an upper and lower fitting for a sight gauge. Total weight is a mere 2.5 lbs including the Usher Aviation filler cap. It is sized for a direct drop in for the Firefly. I will let you know how it works in a few weeks.

    Greetings, In the 11 years I have been a list member, every once in a while, I read with great amusement how people want to change Homer's design because they feel they can do a better job. IMHO nothing is going to just break if you build it to plans so stop worrying so much.

    Subject: Assembly manual on CD
    Does anyone know when Kolb will release the MkIII Xtra assembly manual on CD? I have original "classic" paper plans from the mid 90's. In the mean time if anyone has any details (photos of your own project or perhaps a snippet of the official plans) of the wing tip bow and supporting members from the end of the spar tube outward that would be great. The paper plans are vague at best in this area. I appreciate any help. Thanks.

    Dana, I guess one does have to trust the design and look at the track record. Myself dont see how in the world those tiny pins hold up. But im not about to change such a critical component. You and Mike seam to be pretty brainy about this stuff so maybe you can enlightn me on something. With the pins being so small but apparently strong, why are the lift struts so beefy? You should have seen the barbells for lift struts TNK sent me with my kit [Shocked] they did not fit the lift strut "ends" and I opted to use the ones that kolb has used for ages. If the tiny pin is so strong why are the struts so masive? And have 6 AN bolts in each one? do not archive -------- Paul Petty Kolbra #12 Ms Dixie Final assembly!

    My buddy with the FSII/582 in the hangar next door used to have a Hummer with a Zenoah 250 on it, and a Mikuni pumper carb. The "main jet" was a needle you turned in and out, ala weed eater carb. We took some 1/4" vinyl tubing and slipped it over the high speed needle, stuck the tubing into a 1/4" dowel, more tubing, another dowel, supported the whole rig with some little brackets, and ran the dowels forward to just behind the seat, put a knob on the end, where he could reach back and turn it one way or the other. By watching his egt, he could adjust the carb so that little Zenoah was always around 1050. It ran like a top. He never had any trouble out of it at all.

I couldn't really say, not being familiar with the newer Kolbs... but I'd guess that they're way stronger than they need to be in tension (normal flight), but need to be that strong to handle compression (negative g's and landing loads) without buckling. Dunno 'bout the 6 AN bolts, perhaps to spread the load out on the thinwall tubing? -Dana -- -- The citizens of the United States are getting the government they deserve.

    At 05:06 PM 4/5/07 -0700, you wrote: Michael, I got to wondering what would be the load and stress condition on the strut and main wing attachment pins for the FireFly. I took some measurements from the FireFly. I found: Distance from upper fuselage pin to end of wing - 10.5 feet Distance from upper fuselage pin to upper strut pin - 3.83 feet Angle of strut to wing - 45 degrees. Assuming a gross weight of 500 pounds, one can simulate the loading by placing a point load of 250 pounds at the center of the wing. Below is a crude representation of the wing. "A" represents the upper fuselage pin. "B" represents the upper strut pin(s). "L" is the lift concentrated at the center of the wing over the main spar. We can get away with this because we are interested in pin loads and not the stress distribution of the main spar. "y-up" indicates the load pin is up, etc. y-up y-up A<----3.83'---->B<-1.42'->L<-------------5.25'------------| y-down 250# Summing the moments about Pin A gives: 5.25' x 250# - By x 3.83' = 0 By = 5.25x250/3.83 = 343# Summing forces in Y gives Ay = 343 - 250 = 93# up Looking at the strut attachment, we know it lies at a 45 degree angle. Therefore we know that Bx has to have a value of 343 pounds. Multiplying by the square root of two tells that the upper strut attachment pins must share 485 pounds and this total load must be carried by the single lower pin. The upper wing support pin must with stand the square root of 93 squared plus 343 squared, which equals 355 pounds. Therefore for a one g the loads are: Wing fuselage attachment pin -> 355# Upper wing strut pins -> 243# each Lower wing strut pin -> 485# The FireFly info states it was designed for 4 g yield and 6 g ultimate. For the single lower strut 5/16 inch OD pin the corresponding loads would be 1,832# and 2,910#. Looking at the lower end structure the pin is supported in a 9/16 inch wide clevis. Calculating the bending stress for the pin with the load placed at the pin center calculates out to be 58,000 psi for 4 g and 92,000 psi for 6 g. The minimum tensile stress values for 4130 is 75,000 psi yield and 95,000 psi ultimate. This indicates for the FireFly there is a safe margin for the pin at 4 g with no deformation. If you want to put it through 6 g the pin may deform but it is not likely to separate. Never thought I would do this. But since the question came up and it is cold and snowing, here it is. It all goes to show that if you are gentle in the way you treat your FireFly, it will be kind to you too. Jack B. Hart FF004 Winchester, IN

I took some measurements Give it a break guys, you are not going to break that pin in flight - period...no way! We have crashed Kolbs into the trees, ground, mashed them so flat (doing stupid things) that the engine was crushed. Killed more than two guys doing it - I shouldn't say that, should I ? BUT "those" pins never failed - I don't think you could make them fail "in flight". It's way easier to find something else to look for. Control linkages or something like that. If nothing else look at your elevator linkage. I could land without ailerons, without a rudder, etc. Maybe without the elevator - been practicing with the trottle. Sorry about the "Easter Bunny" thing if it offended anybody .just a funny picture.
