Dan and Larry, thank you both very much for the replies. Fortunately there is no varnish on the boat or spar so I don't have to deal with that. I'm almost certain that the "white" epoxy" that was used for the initial build is FPL-16 from the Forest Products Labratory. Very good stuff, but I will change to T-88 for the rest of the build as I've used it before on other projects and it is easy to use and reliable.
The water stains in the boat are very minimal so I think that an application of some BID will take care of that issue. As far as the fuselage "hole patch" goes, would it be possible to cut a round hole in the boat and carefully bevel the edge and then insert a plywood "plug" with a similiar bevel to get a nice tight fit and then put a couple of layers of BID on the inside of the fuselage to reinforce the repair? It would take a little "doing" but it would look nice when done. I'm going to use some sheer 3/4 ounce cloth from a model supply house on the outside of the boat when the time comes so I will have a nice finish on the outside of the boat also. One more quick question, Are the rear attach fittings from Dr Dean different than the stock KR-2 rear attach fittings? I thought that I read somewhere in the archives that the Dr Dean rear attach fittings are for the KR-2S wing and that they have a 3 degree bend in them. Is this true or did I simply "misremember" something and it's no problem. I need KR-2 plans so I'll be getting some from RR soon. Thanks again ...

Vernon - 2005 - KR Gathering -------Original Message------- What type of resin was used to make these cowls? I have never seen any that were not Vinyl Ester, you can tell by the aroma when you sand it. You can repair it using any resin as long as you sand the surface to rough. I would just put one layer of KR cloth on the inside and one on the outside overlapping the crack by about 2". I use AeroPoxy. Certainly VinylEster on VinylEster is best, but I don't like to use it and don't like to pay the Hazmat shipping charges and don't like the thought of using a "hazmat". Should I be concerned about this and remove the stained plywood and scarf in some new plywood? It will not be visible so from a cosmetic point of view it is not a problem. I would have to see it to be able to give you a better answer, but if you are concerned about it, you can fix it by laying another layer of plywood over the area and glue it down with T-88, which could be sloppy, or could just put a layer of lightweight KR cloth over it. Whatever you do, be sure that there is no varnish on the area as your glues or resins will not stick to it. Some people glass in the whole fuselage with deck cloth anyway, which I don't recommend. If there is varnish on any area that you need to use glue or resin, sand it off very clean and then vacuum up the residue and clean that with something like Acetone. There is a small hole in the side of the boat just behind the rear spar mounting location, several inches up from the bottom about the size of my fist. What should I do to repair this? No problem. Cut the hole clean. Cut out a piece of the 3/32" plywood used for the skin, larger than the resulting hole. Glue it to the inside of the fuselage. Remember, no varnish and use T-88. A good clamp can be made from 1/4" strips of 2X4 cut just slightly longer than the width of the fuselage at the point of the damage. Stick on the repair patch and brace it with the sticks. Then after that cures, cut out another piece of plywood to fit the resulting hole and glue it in that space. You can hold it in place with aluminum pop rivets or Clicoes if you have them. Fill with Super Fil or something like that. What is this adhesive and should I continue with it for the rest of the build? I would use T-88 and really can't know what the old stuff is. I have Dr. Dean wing attach fittings and I would like to use them on the KR-2 wings with the "new" 15% airfoill. Kind of a KR-2S wing on a KR-2. Any problems with doing this? No problem using the new wing on a KR2, at least that is what I hear on the net. I believe that is what Troy did. Welcome and Happy Building. See you at the Gathering. _______________________________________ Search the KRnet Archives at http://www.maddyhome.com/krsrch/index.jsp to UNsubscribe from KRnet, send a message to krnet-le...@mylist.net please see other KRnet info at http://www.krnet.org/info.html "I can train a monkey to wave an American flag.
