In structural theory, the web of the spar is primarily asked to carry the sheer load of the aircraft at any given point along its length. The spar caps, of course, carry the primary compression and tension loads. With this being true, it seems to me that inside the actual aircraft, the spar webs have little structural purpose - EXCEPT to ensure that the caps are held in proper alignment. That being said, this is the lowest stressed part of the spar web in the aircraft. Furthermore - contrary to intuition - the closer to the middle of the plane that you can drill the holes in the spars, the better off you will be. This is because there will be no shear loads here at all. In engineered "I Beam" floor joists, they ask that you drill holes only in the center 1/3 of the span. Also, in practice, one finds that aluminum spars often have large lightening and stiffening holes in them. So, I would not be too concerned with holes. That being said, I would drill them to the smallest possible size! Hope you can put up with my chatter. -Don >I think of drilling holes through the hollow part of the fore and aft >spars, inside the cockpit, in order to route the various wires, and the >Pitot-Static tubing.

To: krnet@mylist.net Message-ID: <42CB1356.3090603@donsplans.com> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Hello all. Thanks for all the letters and inquiries I have had. I think I got back with everyone who contacted me off-line, but if I didn't, I apologize. I finally got done with a brief catalog of what is on the project, excluding the little stuff. I posted it here, along with photos. Does anyone know if the foam from 10 years ago (still in the Rand Robinson box) would still be good? I would really like it if people could actually come and see this stuff before they buy it, as I do not want to cheat anyone. This is particularly true about the engine, which is still sitting on the plane, and can be run before you purchase. http://www.donsplans.com/kr/kr2stuff.html I do best in email mode, at least until we know what the basic interest is. Let me know if anything looks interesting. 50% sounds great, but I know it still looks pretty pricey on paper! -Don Morris ------------------------------ Message: 3 Date: Tue, 5 Jul 2005 19:13:14 -0400 From: "Orma" Subject: Re: KR> Stub Wings To: "KRnet" Message-ID: <010801c581b7$1fe58160$0202a8c0@ROBBINS1> Content-Type: text/plain; format=flowed; charset="iso-8859-1"; reply-type=original With respect to Dan's comment (let's not go there again, please).

I have not used my brakes yet but there was something recommended in Sport Aviation years ago that I incorporated. I have a small piece of brass tubing inside the nlyaflow (nice spelling) where the ferrule clamps down on the tubing. It keeps the nylaflow from collapsing but lets the brake fluid go through. I used a piece of the tubing from a ball point pen after all of the ink was cleaned out. It was a perfect size.

YEEE HAAAAAAAAAAAAA. !! With the old 600X6's and even more recently with the 500:5's I was seeing approx 155 indicated at full throttle level flight. It would pull about 2600 rpm on the 0-200. This morning the ol' girl was pushing 170 indicated and pulling about 2700 rpm, and several times the ASI was bumping 172 mph or so. Power up Mooney drivers or eat my dust !!!!!! I installed the new style RV pants that didn't come with any directions so it took a bit to make them work but they're on, they look good, and fly great !! The air was really bumpy today so I didn't get any accurate speed runs in. I did get in one eight-way GPS run but it was a bit bumpy and I had to dodge a few clouds. It averaged out to 165 mph which gives me an HONEST 10 mph increase over no wheel pants. I think a good run in smooth air will show a 12 to 14 mph increase. Before wheel pants I'd level out at cruise and the ASI would work its way up to the 155 mph mark when I could get the VSI to settle down. With the pants installed I'd level off and the ASI quickly shot to the 160 mark and when I got the VSI to settle out it was hitting 170 !! Now , even with moderate turblance and a bouncing VSI it stays in the 160 to 165 range. The GPS run, by the way, was at a density altitude of approx 8000 feet so I was probably only getting 22 inches of MP and able to pull 2500 rpm. Also on a low altitude full throttle run I'm picking up an additional 50 to 75 rpm with the increased speed. My problem now will be taking them off long enough to finish them. All I can say is " you have to catch me to tell me they look tacky" !! I am one "happy dude" with one "mean machine". And I thought I had something to YEEEEE HAAAAAAA about before.......

I had no idea that it would make that much difference Ours are waiting for the hours to be flown off so I don't have to take time away ffrom the possibility of making the gathering with the WannaBee that soon WillBee. See you in Mt. Vernon - 2005 - KR Gathering See N64KR at http://KR-Builder.org - Then click on the pics There is a time for building and a time for FLYING and the time for building has expired.

As for wax around the staple holes, many parts of my plane were laid up in molds waxed with the same wax. It cleans up easily enough that painting wasn't a problem. It will be a while before I paint these parts, but really don't anticipate any unusual problems.
