Since it's not epoxied in place yet, I want to try and fix this. I was thinking of "splitting the difference" by sanding away 1/16" on the aft side of the left wing spar fuselage opening and 1/16" on the forward side of the right wing spar fuselage opening then shimming in place to get the spar to set square to the firewall.

In other words, you do NOT want to encounter the inner straw every 10" as you push the brake line in. If you can insert the brake line from either direction, then it is not as critical.

I wrapped it around the front and fared it back to the trailing edge like an airfoil. I used liquid foam I got at a marine shop, with several pieces of plywood and some wax paper to keep the foam from sticking to the wood. Once I had the gear formed and sanded, I glassed it over, sanded, filled, sanded then painted with primer. Looks good. I got to within 1/2 inch of the body of the KR and filled the gap with butyl-rubber for flexing properties.

I used a kludged wood structure that mounted to a disk harrow attached to my riding yard tractor. Using bungie cords to secure it was marginal due to cord flexing and rougher than desired surfaces. I am currently building an assembly that will mount on my truck trailer hitch, extending back maybe 7' to the assembly that holds the tailwheel. That assembly will roll on two large diameter pneumatic tires and include a swiveling platform that actually secures the tailwheel. That way, between the swiveling of the hitch and that of the rear structure, I should not place any structurally bad forces on the tailwheel.

I would not recommend it without a lot of thinking and engineering calculations. Each part that is changed requires more changes in the structure and aero design. Increases in size mean increased weight, which means either a reduced load factor or a heavier structure. All of these changes also increase the time required to build.

Recall that when I last weighed it it weighed 36 lbs all up. It had micro on the spars and cloth overlaps but no finish. I applied one brushed coat of epoxy primer to seal pin holes etc (sanded till a little glass and micro showed here and there), then two coats of feather fill (sanded almost off..till primer came through at the high spots for both coats) and a couple of brushed on dabs of feather fill at the remaining low spots. Now the wing is ready for a final coat of primer then paint. I now weighs 38.5 lbs. The filling process weighs 2.5 lbs for about 50 sq ft of surface (according to my unreliable bathroom scale). It's not a precise weight but it does give an idea of how much the filler kinda weighs. Hopefully in a week or two I can also tell you about the weight of the paint. I'm a little disappointed it weighs so much...maybe 15 lbs for the whole aircraft. That's two more gallons of fuel or a fatter passenger I'm giving up for a pretty finish. I hope it goes faster as a reward. - -Peter- ------------------------------ Date: Sun, 15 Jun 1997 19:01:04 -0700 From: David Moore Subject: KR: KR2S Plans with Serial for sell Special Notice, I have a set of KR2S plans I would like to sell, they are in excellent condition with each page in its own plastic document protecter, in a loose leaf binder.

Of course 1/16" ain't much to remove from the vertical fuselage member, but that's still 10% of your 5/8" structure (not counting plywood). I made a centerline on my upper firewall brace, and another near the tailpost (just measured as the center, left to right) and used a large framing square to determine if firewall and spar were perpendicular. They were, but if they weren't I'd want to know so I could compensate with engine mount dimensions. But as for spars being perfectly perpendicular to the fuselage, propwash will mattter more...

Tony Bengelis has a chapter on this problem in one of his books. But as Mark says, the plane might not care. If I was buying it used, I would care though if I saw one wing section being more forward than the other one... Mark may be right about it being your firewall that is off here, I would look into that. Otherwise, I think your sanding approach is fine. I would add some kind of doubler oppposite wherever you remove something to keep the strengths the same though. Make a center mark on a fuselage cross piece somewhere a few feet back from the firewall, then measure from that mark to the same respective point on both left and right sides of the firewall. They should be equal or real close. If they are off, then your firewall isn't square with the centerline. (You will be comparing hypotenuse length measurements.) I don't know if this is any of your problem but that 1/8" is about the amount of expansion you can get from particle board shifting with humidity changes over an 8 ft length. I have had to deal with this myself; I would get plywood for my table top next time, unless I was in a more stable work area than I am now (hangar). imho, Robert Covington > >---------- >> From: JEHayward@aol.com >> To: krnet-l@teleport.com >> Subject: KR: Wing Spar Squareness >> Date: Sunday, June 15, 1997 11:53 AM >> >> I've encountered a little problem.

I agree, I mounted my aft spar tonight and either I am damn lucky or just plain GOOD! Both my spars are right where the should be and the aft spar is perfectly aligned with the front spar! Yes,... I am smiling! I also painted my interior this weekend and I just went over to remove the masking tape I used around the windows. The tape was only on the window for about 5 hours but the splatter paint must have attacked the tape some how because it left some of its sticky goo adhesive behind! I will wait until the paint is 100% dry before I try to remove the goo, Mark did you find anything that worked better than car wax? I built up my NACA ducts for my fresh air inlets yesterday, they came out pretty cool! I will be posting pictures of all this tomorrow. Tomorrow night I plan to mount the sling seat , control stick and pulleys and brackets. Speaking of cables sitting higher than the seats, Since my KR is wider I will need to cut my sling seat in half and leave a 3 inch gap in the center, but this is good because now I plan to make a center arm rest that will sit over the cables. WOO HOO chalk up another win in the "change things" column!

Actually I think mine are perfect because I drew up full size plans on a roll of brown wrapping paper and built both of my fuselage side directly over them. When I hung them on the wall they were identical! Really they were, and you don't know what joy it is to slide in both of those spars and see them lined up as perfect as a platoon of Marines on Graduation Day! :-) Uurahh! _______________________ ~~~~~~~~~~~~~~~~~~~~~~ Micheal Mims Just Plane Nutts mailto:mimsmand@ix.netcom.com http://www.netcom.com/~mimsmand ------------------------------ Date: Sun, 15 Jun 1997 23:09:48 -0700 From: Micheal Mims Subject: KR: Wing Tank Gauge What type of fuel tank gauge has worked in the wing tanks? What kind of gauge are the people without electrical systems been using? I am using a regular sight type gauge on my main tank but I dont think this will work on the aux tank (6 or 7 gal tank in the right stub). I think by regulation we have to have a gauge on each tank or I would just blow it off. It will only be used once per flight to transfer fuel to the main tank so its either empty of full, who cares whats in between? _______________________ ~~~~~~~~~~~~~~~~~~~~~~ Micheal Mims Just Plane Nutts mailto:mimsmand@ix.netcom.com http://www.netcom.com/~mimsmand ------------------------------ Date: Sun, 15 Jun 1997 23:39:35 -0700 From: Micheal Mims Subject: Re: KR: Wing Tank Gauge At 11:09 PM 6/15/97 -0700, you wrote: < Subject: KR: Re: Wing Spar Squareness/Table >At 08:59 PM 6/15/97 -0700, you wrote: >>I don't know if this is any of your problem but that 1/8" is about the >>amount of expansion you can get from particle board shifting with humidity >changes over an 8 ft length.

(it is 16 ft long, 2 boards) I sealed them up and that helped some with expansion, but I worry about stressing drying joints as the verticals try to slide along the longerons with the table, so I wait for stable weather. I should have just gotten plywood, then I could have built them all in a weekend without all this paranoia (a lot of that engendered courtesy of the RV building KR haters in my hangar) Robert Covington ------------------------------ Date: Mon, 16 Jun 1997 07:21:08 -0400 From: Marty Hammersmith Subject: Re: KR: Need a KR ride (no archive) >Weight and CG is still TBD.

She's willing to take some flight instruction but only from a female instructor. She's been a big help. Two weekends ago she helped cut all the gussets for the rudder & vertical fin for my Horizon 2 project and last night she helped cut out the first set of plywood ribs for the 12 meter Woodstock sailplane we just started. I keep showing her the KR plans but I never should have shown her the GP-4.

I drilled a hole for the axle of the tailwheel, and bolted two "L" shaped brackets to it that fit over the leaf spring (snugly) then mounted a trailer mount (7/8") to it. Provided you don't hit a "pot hole" or go over a bump at warp speed, the hitch should hold just fine. Once rolling, the lateral pressure on the tail mount is faily constant but not extream. The verticle stress is absorbed by the leaf spring, which is taking very little of the overall weight since the tail is high and places most of the weight on the mains. Just make sure your prop is not verticle, and don't make a hair-pin turn or try to mount a curb in reverse. The only forseeable problems are that the wheel mount is not designed to be pulled and may bend, (that is why you use 2 "L" brackets) and you may have to buy a trailer license for the KR to tow it over area roads. - - Cary - ------------------------------ Date: Mon, 16 Jun 1997 08:41:39 -0600 (MDT) From: Ron Lee Subject: Re: KR: Towing a taildragger (no archive) >The only forseeable problems are that the wheel mount is not designed to >be pulled and may bend, (that is why you use 2 "L" brackets) and you may >have to buy a trailer license for the KR to tow it over area roads. > >- Cary - > > Fortunately I have taxiway access from my lot to the airport so a License will NOT be needed. And I am trying to place most of the load on the leaf spring. Your idea sounds very good but since I already have the parts, I will try this way first.
