  • bow splice

    Can a tip bow be spliced. I need to replace about 6 inches that has a rust pocket- what material are the struts made from, mild steel or 4130?

    Thanks

    Hey Wade,

    Sure the steel bows can be spliced and I guess that's what you are talking about.

    AC43.13-1B gives details for steel tube splices.

    I 've seen claims that the lift struts were made of either depending on the year of manufacture.

      Just order some 1/2" .035 4130 and make some new ones, its faster than repairing and better in the long run.

        If you have a good pattern , a complete new one is best, remember they are not rounded like the Cub, C.G. Taylor had definate thoughts on the flow off the tip and they are kind of flattened between the spars ( not complete flat but not way out ). THEN make sure the little wire is there to keep the tips of the spars from spreading when taxiing over rough ground; negative laod protection is afforded by the wire; it was a SL way back.

          Forrest: We need to put you in a grape press and squeeze all your storehouse of fabulous knowledge out at once, put it in a bottle (read: CD) and distribute it to all who own Taylorcraft! Example: I just read your last thread about the tip bows, went to look at the 3 I have here. None were slightly flattened between spars, and there were no small wires at the tips to prebent spar tip spread, per the mentioned old Service Bulletin. All were pretty weak looking, rusty or bent. Probably they were replacements from decades ago. So, thanks for setting me straight about what really needs done at the tips. Any chance you can thumbnail a pic of a true tip bow and/or the brace wires? Best regards, Bob Coolbaugh

            Yep mine were flattened a bit. I thought they would need to be rounded out when I finally get around to putting them back on. But no wire between the spars. Larry

              Now I'm going to have to look at mine to see if they were done properly when it was rebuilt from the ground up back in 1999. I won't tear the bows out, but it would be nice to know how close to original the wings were built.
              Forrest, do you have a CD of the wing drawings for a pre-war BL65? Thats the next stage in the re-construction of the Israeli war bird. Brie

                Couldn't reduce the scans enough for the forum but just put up a drawing and 2 part #'s pages from the Model "B" Parts Price List on my Gallery pages. T-craft owners and their planes page 9, then last three scans on my page 7.

                  Thanks Howard. I'm at the library right now, and don't have my laptop with me. I don't remember how to get into the gallery, so I'll have to wait till I get home where I have it hotkeyed on my laptop. Brie

                    Just put up a B model wing dwg and a Lyc installation dwg for a B12. To get to the gallery go to the blue line on the bottom of this page and click on the Taylorcraft Foundation. Then click on the blue Gallery link on the foundation page....

                      Howard,
                      I followed your instructions and found such a wealth of information. I loved the drawing of the air cleaner for the O-145 engine complete with Chevy part number.
                      That top wing on your "next project" is awfully low. Do you look under it, or over it? Brie

                        Under it, I hope. Most of the flying pics I see of them the pilot's line of site is just above the cowling. Haven't had too much time to play with it yet. The seat has been welded in and I'll need to work in room for a chute somewhere. Lookout Cirrus! Been getting the barn cleaned up and weatherized so I can start on the T, rejuvenating dope, rib stitching some old mouse damage, and an engine swap. Hopefully in time for the Alliance fly-in this year. Then comes the bipe. Yeah, isn't that chevy air cleaner a hoot? Flylo says he has one on his '38!

                          Egads , Howard Wilson, he and lovely Bride , Sue visited Alliance for a full day. I can take picture of bow soon, Heck even Howard with his 30 yr Librarian wife had not used ALL the functions of the web site & forumn to search for stuff. The Rodman library site now has around 600 scanned pictures.
                          My advise to newbies is to take an evening and search

                            And what a wonderful day and a breakfast it was. As soon as we got home I jumped on the Rodman site and found over 500 pictures of Taylorcraft history!! Last time I had looked it had been about 6 pages. What a great resource. It was good to see such a vital library serving so many user groups in these days of budget cutbacks. Forrest showed us the F-19 factory, and the old Taylorcraft factory from the outside and we are looking forward to a possible inside tour during the flyin this year. The keylime pie at Corny's was fantastic, and Forrest is a fount of information on the historic down town buildings. Patti filled in on the things he left out. Went to breakfast with one of the factory test pilots (90 years old), he got his license in 1939, flew the Hump in a C-46, might have been the test pilot on my '39! The restaurant at the Salem? airport was very goood and had some great aviation decor (including a KR-1 hanging inverted above the dining area). Maybe we can do a flyout breakfast or lunch from the flyin?? Probably less than 10 mi?, haven't looked at a chart. Forrest thanks for the time and effort you put into our visit. Sue and I enjoyed it very much.

                              That is what I exist for!! YES we do fly-out Breakfasts & lunchs during the Fly-In time but I try to keep folks on the field on Sat & Sunday. Come early and play there are MANY places to fly out to around Alliance, even stay after the Fly-In too! See u soon Howard & Sue. That test Pilot was Sanford O. Slifkin , SOS in many log books.
