    Subject: Loose Spar Cap
    --> Kitfox-List message posted by: "Don Pearsall" <donpearsall@comcast.net> Rick, The only "good" way to fix this is to open up the fabric near your rib so you can clean the parts and re-glue with more structural adhesive. The rib cap only touches the spar at a small area, so the looseness you feel may be the rib and cap separating. Of course the rib attaches to the spar with adhesive, and that IS structural. Just injecting more epoxy in the area may not get the right spot, and given that the parts may be dirty or covered with Poly-tak, poly-brush, etc, the glue may not stick anyway. My vote is to open it up and do some surgery.

    --> Kitfox-List message posted by: Lynn Matteson <lynnmatt@jps.net> You'll get more suggestions, but the first thing that comes to my mind is that most 5 minute epoxies are not as strong as their "longer" cousins...in other words, use the longer-setting epoxy for lasting longer and better strength. But It seems to me that you'd want to use what was originally used,probably structural adhesive.

    Subject: Re: Loose capstrip?
    --> Kitfox-List message posted by: "flier" <FLIER@sbcglobal.net> Rick, The capstrips run on the top and bottom of the ribs and provide rigidity for the rib and secondly as a place for the fabric to adhere. The ends of the ribs are adhered to the spars with structural adhesive. The ends of the capstrips end up being glued too. So, do you have a loose rib or just a loose capstrip? Which one? If only the end of the capstrip is loose at the spar, I wouldn't sweat it. If the rib is loose, depends on where it's at. Need a little more info...

There is a chance that not only epoxy but a brad is helping hold the works together. I would consider installing an inspection cover in the area of the looseness so you can get inside the wing. You might be able to do the repairs without cutting open the fabric (except for the inspection cover). Once done, pop in a cover and nobody would ever be the wiser. If it's the cap come loose from the rib, you might consider installing a small piece of 90 degree alum angle where the cap and rib come together. This will give you a lot more epoxy holding surface. Better yet, use a piece of 90 degree wood with a piece of either side (would probably stick better than alum). BTW, I've tried many of the cheaper fast setting epoxies from the hardware store and non seem to even come close to something like West Epoxy System.

    Subject: Tacho connections
    --> Kitfox-List message posted by: "Rex & Jan Shaw" <rexjan@bigpond.com> Since it's AC coming from the alternator, shouldn't matter which of the two (yel or yel/blk) you use, should it? Presumably second wire from tach goes to ground? What do you think Rex? Yes the second wire from the tacho goes to ground or earth whichever you prefer to call it. The yellow and yellow/black are power output leads from the alternator and go to the rectifier/regulator. I gues if you are going to get a satisfactory pulse from one of these leads there is no difference between one or the other as far as is shown in the books or I can imagine. I suspect both leads just go to a bridge rectifier. However I question that these leads are correct to use. Normally as you have mentioned the grey lead is the correct one. I fail to see why you haven't got that. True on some versions there was an internal 1K resistor in the coil assembly that failed and that effectively open circuits the grey lead. Next they did away with the internal resistor and fitted it externally in the grey lead. After that it was fitted in the tacho itself. Now there is two coils to feed the two modules both are white leads one end and green the other. The white leads are earthed. One coil is tapped with the grey lead for the tacho. I don't know but if you have no grey lead for some mysterious reason then maybe you could use one of the green leads however there will be a higher voltage pulse on this than the grey lead so I would be starting testing with a higher value resistor in the line to the tacho like perhaps 10K and working down from that if needed.. I think this makes more sense than trying to get a pulse from the yellow or yellow/black alternator wires. Assuming you take the tacho pulse from one of the green leads through some value resistor that works OK I would stress to then very carefully check your ignitions on both circuits in case taking your tacho pulse in this way is having some adverse effect. I can't say more except maybe a pulse taken off the charging coil might indeed work but it does not seem the best way to me speaking as an electronics tech. OK I hope this helps you out. I am off in a minute for a few days flying and camping. Goodluck. Rex Shaw Australia. rexjan@bigpond.com

Is > twisting better with some liquid tape?? > Hi Jared, Well, if this is for an "emergency" repair, twisting would be ok., but use "heat shrink" with glue. For a more permanent setup, I would use some kind of connector. The Mil. type can be found in any rating and size, but they are much to heavy - much to expensive etc.. Twisting would also be OK. as a permanent solution, however, every time the engine go out - your wire length decrease :( . I would use the AMP Mate-N-Lock, the UL94V-XX. XX would be your selection of number of pins, female or male. etc. The pins are rated up to 15 Amps, (handle AWG 22 - AWG 14). Those connectors is light weight and is priced right!! They are open, water can go in, so- use uphill "method" and a large heat shrink tube, this time without heat treatment just some straps and you'll be fine. You'll need some tool for crimping those pins, and the original are expensive. However, I know that some chapters around have tools members can borrow. Here you'll find some crimping tools, as the B-Crimp "Medium" wire Open Barrel. http://www.bandc.biz/cgi-bin/ez-catalog/cat_display.cgi?9X358218#BCT- Here is a little more info about the type of connector, they look very like the UL94V - but are not. The kind shown in Bob N's web site is 0.093 pins and can hold 11 Amps. http://www.aeroelectric.com/articles/matenlok/matenlok.html Hope this help. Torgeir.

    --> Kitfox-List message posted by: Jerry Liles <wliles@bayou.com> I don't know exactly what resin is used by JB Weld but in color, viscosity, and texture it appears similar to other industrial epoxies. It certainly has excellent strength and adhesive qualities. I've used it before and made coupons for testing. With wood the bond always exceeded the wood strength and bonds to properly prepared metal were always very strong. I've copied some of the information from the JB Weld site and included it. Properties (psi) Tensile Strength: 3960 Adhesion: 1800 Flex Strength: 7320 Tensile Lap Shear: 1040 Shrinkage: 0.0% Resistant to: 500 F Mechanics -- you can use J-B WELD with confidence. It is designed for safe, reliable, permanent repairs in engine compartments and heated environments up to 500 F. It's strong as steel and impervious to water, gasoline, chemicals, and acids. Working with J-B WELD is quick, easy, and convenient -- and saves you time, work, and money! Not recommended for use on manifolds, exhaust systems, and other engine components which normally operate at temperatures above 500 F. How to use it: Use J-B WELD as an adhesive, laminate, plug, filler, sealant, and electrical insulator. Squeeze out equal portions from the black and red tubes. Mix thoroughly. Clean surface to be bonded. Apply J-B WELD, and let it cure. That's all there is to it! Like metal, J-B WELD can be formed, drilled, ground, tapped, machined, filled, sanded, and painted. It stays pliable for about 30 minutes after mixing, sets in 4-6 hours, and cures fully in 15-24 hours. It's water-proof; petroleum-, chemical-, and acid-resistent; resists shock, vibration, and extreme temperature fluctuations, and withstands temperatures up to 500 F. J-B WELD is super strong, non-toxic, and safe to use. Before it sets, you can clean up with soap and water. (print instruction sheet) <http://jbweld.net/products/instruct_jbweld.html> Uses <http://jbweld.net/products/uses.php#jbweld> What does it bond to? Virtually any combination of iron, steel, copper, aluminum, brass, bronze, pewter, porcelain, ceramic, marble, glass, PVC & ABS, concrete, fiberglass, wood, fabric, paper -- just about any porous and non-porous material.
