    The link below makes it clear as mud. I have had a restricted radio operators license since 1966. I have never been asked to produce it. I wouldn't worry a lot about it one way or the other. It is like a pilot certificate...good for life unless revoked. I think it is free as well. Just fill out an application form. http://wireless.fcc.gov/commoperators/index.htm?job=rl -------- Jerry Dotson 59 Daniel Johnson Rd Baker, FL 32531 Started building NX510JD July, 2009 Ribs and tailfeathers done using Lycoming O-235 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=281007#281007

    Has anyone tried this stuff (HTS 2000)? It is a special type of brazing rod that can be used on aluminum and other materials. They claim that it is stronger than traditional welding techniques. I am making my control horns from .250" 60601 aluminum and I will need to TIG the ears on. I'm considering giving this material a try with a simple rose bud tip on my oxyacetylene rig. If it works as well as they say, I may just braze up my fuel tank with this stuff. It is kind of expensive, but so is a TIG.

    The completed joint will be dead soft, it will be annealed. While that might be suitable for fuel tanks, I sure wouldn't use it for my flight controls! No way. Not at all.

    Mark, I have looked at it and wondered if it really worked as well as the demo video illustrates. My final analysis was that it is quite expensive and not too certain about the claims and reliability. I for one would be interested in learning the results of your trial. The demo makes it look too good, too easy to do, that in my book means too good to be true. Too much skepticism here but always willing to listen to the results of a reliable source, let'er go and let us know. Just for discussion sake I just bought an AC HF century spark box for my TIG rig so I could weld aluminum, figured once I wasted all the high cost braze rods and sheet stock on something that wasn't going to work for me, I could expand my TIG set up and have the equipment asset for as long as I wanted and TIG weld all the aluminum stock I wanted. I guess we all have a chance to learn something from this endevor. Buildapalooza 09 and 2010 John In a message dated 1/11/2010 11:02:38 A.M.

    Thanks all for the comments. I will probably look into the 109MR or 194MR number. Also wondering how th e X would be added to the front - I typed that in the FAA registry search a nd it comes back invalid too. Tom B. From: tmbrant@msn.com Subject: Pietenpol-List: Inspiration Well=2C my father-in-law died today after a 2 year fight with cancer. He h as been a true inspiration and he will be dearly missed. Him and his wife built one of the wing ribs for my project and I asked them to sign it. A f ew months back I asked him to think about something significant in his life relating to numbers and letters. I wanted him to be remembered by the tai l numbers on my Piet (if I ever finish it). He wasn't able to come up with much but he suggested I use the date of his death along with his initials. So - how does 19MR sound? Unfortunately N19MR is taken... So - any sug gestions how I can work this into the number? I tried 019MR and it said th at N-number is invalid - does that mean that it's not taken??

    Well, I'm not entirely sold, just curious. I did however talk to one of our machinists about this stuff. He agreed that this stuff is interesting, but that I would probably be changing the temper of the material in order to apply this stuff, then he opened his tool box and handed me a stick to try. I'll probably use some of my drop material to test this stuff. I understand what you are saying David... the bond may be strong, but the properties of the surrounding material may be changed. I guess that my next question would be... how much? Annealing is to make softer, not brittle, right? I'm just wondering if it would be so weak that the aluminum would fracture or bend or break before the hardware would be ripped out of the wood parts it is attached to. Actually, I suppose that is the big question. Maybe I can set up some tests to determine the strength of my material after applying this stuff. -------- Mark - working on wings Read this topic online here: http://forums.matronics.com/viewtopic.php?p=281053#281053

    All, I wanted to plea again if anyone can help me locate this listing. From what I remember it was a listing of about 10 Pietenpols. It detailed fuselage length, tank location, and engine, weight and some weight and balance info. I've searched the archives, My Kitplane and Westcoast Piet. If anyone can locate please let me know. Thanks, Jack DSM

    According to AC 45-2D, para 7A2c, you can insert the X, as in NX1234A, without a problem. You would get N1234A from the FAA and then put the X in when you did the paint. Read this topic online here: http://forums.matronics.com/viewtopic.php?p=281055#281055

    Wayne. I wholeheartedly agree. I just tidied up some of my new format Sport Pilot magazines and put them away with some of my old EAA Experimenter magazines. What a difference between the two formats. Sport Pilot contains mostly powered parachutes and ready to fly eastern European LSAs where as the old experimenter is chock full of Tony Bingelis "how to" articles about scarfing and making homemade wood steamers.

    Subject: Re: HTS 2000
    How much is a difficult thing to guess, since the entire process is uncontrolled. The temperature profile isn't known, and the time at those temperatures is not known or even planned. The materials in the braze aren't known, any more than the ways that stuff affects the base metal. MIL-HDBK-5, the strength bible for metals, has a section on brazing that doesn't even cover aluminum. I'd say the actual strength doesn't matter. The Pietenpol builder generally doesn't have a process to follow, a brazing oven where the process, if there were one, can be controlled, and samples that he can evaluate quantitatively. Whatever strength a particular joint achieves is unlikely to be replicated at the next joint. This is absolutely not suitable for flight controls! It might be worth considering for fuel tanks, which can be pressure-tested fairly easily - and ought to be, too.

    Mark, I don't know anything about HTS 2000, but if you're thinking about welding aluminum, and making your control horns of solid aluminum, refer to this post I made to the list July 24, 2008 (food for thought): Posted: Thu Jul 24, 2008 8:21 am Post subject: Aluminum in place of metal fittings Mike, In general, if you plan to substitute materials from those shown in the plans, you had better know what you are doing. For instance, with regards to substituting aluminum plate for the control horns, you should be aware (maybe you are already) that if you weld aluminum, many alloys are severely weakened at the weld location (for 6061 the reduction is about 40% within one inch of the weld). Aluminum also does have a fatigue limit, unlike steel. What this basically means is that steel will not be affected by fatigue (repeated cycles of tension and compression) unless it is stressed above a certain level, whereas aluminum will feel the effects of fatigue at any level of stress. Eventually, the aluminum could develop cracks due to fatigue. Also, the solid aluminum control horns will definitely end up heavier than the hollow, formed sheet metal horns shown in the drawings. As an example, the aileron control horn has a surface area of approximately 19 square inches on one side. Two thicknesses of 22ga (.03") mild steel (or 4130) will weigh about 0.33 lb. One thickness of 3/8" aluminum will weigh approximately 0.7 lb - or twice as much. Of course, you could machine the aluminum into a bit of an airfoil shape, which would save a few ounces. But then you will still need to add bracing angles and nuts and bolts to mount this solid aluminum horn. Attached is a photo of such an aluminum aileron horn (by someone else), which was cut from 1/4" aluminum plate. I would estimate that this whole arrangement weighs approximately 2 to 3 times as much as a plans-built control horn. So, in conclusion, just make sure you do your homework before you start changing from the plans. Bill C. Read this topic online here: http://forums.matronics.com/viewtopic.php?p=281102#281102

    Thanks guys, I do appreciate your advice. I had never heard of HTS 2000 or any of the other aluminum brazing rods until today. I just found it interesting that it seems to be so strong. As for the aluminum control horns I really havent done any serious analysis or destructive testing to confirm that 6061 will stand up to the same stresses that formed sheet metal will. I do know that 6061-T6 claims to have a tensile strength of 42,000psi and a yield strength of 35,000psi. Hardly the characteristics of 4130 steel, but much more than my 1/2 spruce aileron spars would allow. I really didnt think about the annealing that would take place during the heating of this material. I know that welding aluminum is acceptable, but not in structural assemblies. I suppose TIG is the most effective and least harmful method (to the material), but oxy-acetylene is supposed to be acceptable too, although it would distribute even more heat over a wider area. Again, I understand this to mean non-structural assemblies like fuel tanks, cowlings, etc., as even TIG welding will soften the welded area to 6061-O (tensile 18,000psi, yield 8,000psi). Ive also read that the assembly could be heat treated to restore its strength. Im not certain about this but I guess Ill need to consider that too if I want the full rated strength of T6. Ive seen a couple of different aircraft that use aluminum control horns. One example is on a Pietenpol that was built by a local EAA member. Ill pick his brain as to how he affixed his tabs and dealt with annealing. Perhaps he did nothing at all, or maybe he will enlighten me on his approach. I do know this he has many hours on his airplane (his 5th) and is a well respected builder, even in the Pietenpol community. Im not saying that as a dig at anyone, I am only stating it to point out that I chose to duplicate some of his features because I figured that he knew what he was doing (an assumption), and because they look pretty cool. As for the weight of these items, I assume that you are comparing 1:1 dimensions for these materials. The example I studied has lightening holes, which I also plan to implement. I know, I know there are probably 1000 arguments for or against the lightening holes too. Well, hopefully I can provide some answers after my next discussion with this fellow. Thanks again for the comments. They sure do help get the ideas flowing, and help me formulate better questions when discussing these issues with others. -------- Mark - working on wings Read this topic online here: http://forums.matronics.com/viewtopic.php?p=281120#281120 Attachments: http://forums.matronics.com//files/p9260051_768x576_157.jpg

    Subject: Pietenpol
    Mark... It's been quite awhile since I've heard anything about your project. Are you able to work on building any ribs or do any other work? I'm still working on mine regularly. I may even finish it one of these years. :) Mike Groah Tulare CA ________________________________ From: Mark Roberts <mark.rbrts1@gmail.com> Sent: Sun, October 25, 2009 6:43:02 PM Subject: Pietenpol-List: And the real work begins... Well, after futzing around for a few weeks with my 613.5 rib jib jig, I have finally invested in some rough cut poplar, and turned it into little sticks yesterday. I went over to my friend Ray's house, and we spent the day cutting about 15 or so board feet of wood into 109 6 foot long sticks 1/4" x 1/2". We had a lot of fun, and I am looking forward to getting the T-88 and beginning to glue them all together. I still need some 1/16" marine ply (any suggestions on a cheaper source on this?) but I can at least start cutting the poplar into even smaller sticks now. It took us 7 hours, and a lot of sweat, but we had a lot of fun doing it. Ray and I cut parts for 2 cradles in this same area 19 years ago when my wife and I found out we were going to have twins. He had the plans, and we cut the parts in the same drive way we cut the poplar in yesterday. Funny how things repeat and how important good friends really are. I posted all of the pictures we took during the process, including the peg jig I made for the Riblett 613.5 jig I made. I finally decided on this airfoil based on a lot of thought. I drew out the rib plot in my CAD program, then offset the lines by 1/8" and used that line to place a series of 1/4" holes .75" deep. I made a bunch of 1.25" long pegs out of 1/4" diameter maple dowels and hammered/glued them into place. I used my 3 axis mill to do the drilling so I have a 'perfect' plot of the airfoil, and all the alignments of the pieces are perfect! It's nice to slide the 1/4" pieces into place and have them fit like a glove! So, all I need now is to order the T-88 and some plywood for the gussets and I can start the assembly process. Oh, yeah, before that I need to cut those little sticks into many smaller sticks! Well, let the cutting begin! Here's a link to the picture folio of the day yesterday, with shots of the jig as well. http://picasaweb.google.com/RobertsChristmas2007/PietenpolProject?authkey=Gv1sRgCJiF__Tq2bugtgE&feat=directlink Mark
