The link below makes it clear as mud. I have had a restricted radio operators licensesince 1966. I have never been asked to produce it. I wouldn't worry a lotabout it one way or the other. It is like a pilot certificate...good for lifeunless revoked. I think it is free as well. Just fill out an application form.http://wireless.fcc.gov/commoperators/i ... -----Jerry Dotson59 Daniel Johnson RdBaker, FL 32531Started building NX510JD July, 2009Ribs and tailfeathers doneusing Lycoming O-235Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: HTS 2000
Pietenpol-List: HTS 2000
Original Posted By: "David Paule"
Has anyone tried this stuff (HTS 2000)? It is a special type of brazing rod thatcan be used on aluminum and other materials. They claim that it is strongerthan 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 thismaterial a try with a simple rose bud tip on my oxyacetylene rig. If it worksas well as they say, I may just braze up my fuel tank with this stuff. Itis 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.David Paule----- Original Message -----

Subject: Re: Pietenpol-List: HTS 2000Mark,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 2010JohnIn a message dated 1/11/2010 11:02:38 A.M.

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

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.David Paule----- Original Message -----

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 madeto the list July 24, 2008 (food for thought):Posted: Thu Jul 24, 2008 8:21 am Post subject: Aluminum in place of metal fittingsMike,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, manyalloys are severely weakened at the weld location (for 6061 the reduction is about40% within one inch of the weld).Aluminum also does have a fatigue limit, unlike steel. What this basically meansis that steel will not be affected by fatigue (repeated cycles of tension andcompression) unless it is stressed above a certain level, whereas aluminum willfeel the effects of fatigue at any level of stress. Eventually, the aluminumcould develop cracks due to fatigue.Also, the solid aluminum control horns will definitely end up heavier than thehollow, formed sheet metal horns shown in the drawings. As an example, the aileroncontrol horn has a surface area of approximately 19 square inches on oneside. Two thicknesses of 22ga (.03") mild steel (or 4130) will weigh about 0.33lb. One thickness of 3/8" aluminum will weigh approximately 0.7 lb - or twiceas much. Of course, you could machine the aluminum into a bit of an airfoilshape, which would save a few ounces. But then you will still need to add bracingangles and nuts and bolts to mount this solid aluminum horn. Attached is aphoto of such an aluminum aileron horn (by someone else), which was cut from1/4" aluminum plate. I would estimate that this whole arrangement weighs approximately2 to 3 times as much as a plans-built control horn.So, in conclusion, just make sure you do your homework before you start changingfrom the plans.Bill C.Read this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Well=2C my father-in-law died today after a 2 year fight with cancer. He has 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 few 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 tail 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 suggestions how I can work this into the number? I tried 019MR and it said that N-number is invalid - does that mean that it's not taken?? ________________________________________________________________________________Subject: Pietenpol-List: Re: HTS 2000
