Pietenpol-List: Wing border

Post by matronics »

Original Posted By: "giacummo"
The smaller, more transportable and higher tech... the more expensive...Therefore, what I bought was, the venerable Miller Synchrowave 300. It's a BEASTof a reliable OLD unit that I see on ebay regularly for $1000. While a 300amp machine, commonly listed as 3 phase, it's NOT, it's built and designed foreverything from 220v single phase, to 575v three phase, doesn't matter. I'vegot mine on a simple 40amp 220v breaker and weld 1/8 stainless at 150 amps withno problem. Just haven't tried larger stuff yet.Insofar as reliability and it being old, if the transformer is good, it's affordablyfixable. There are two pc boards and I just had both fixed for $200 total.So really, that's sort of worst case. The synchrowave 250 and 350 are newersquare wave machines that should be about the same, so if you can get oneof those for as cheap, I'd go that way.The drawback... it's BIG. Like 800lbs and five feet tall on a cooler. However,it rolls around as easily my MUCH smaller MIG welder.Saw two on ebay yesterday for a grand, so they're available. You'll also see abunch for $3500 or so, new it's probably in the six grand range. It's a NICEwelder. I don't know about Lincoln, but Miller is REALLY nice to deal with. Online andfree are ALL the manuals for these machines. Parts from them are super expensive,but they're so common in industry that there's LOTS of aftermarket support.They also sponsor a nice forum from which you can gets lots of expert advicein the use, care and repair of these neat old industrial machines. Not really on topic, but my MIG welder is a Miller CP-200 with a wire feeder. It's a 3 phase machine easily converted for about 20 bucks. You see them on ebayin the three to five hundred range with wire feeders. It's ALSO a reallynice super reliable machine that loafs along spraying .035 wire on a 20amp circuitI have set up for it. If anyone needs a nice wire feed that's adjustableenough to use on everything from auto sheet metal to 1/2" thick tractor parts,consider one of these.Google Haas-Kemp Miller CP-200 Welder Conversion for more info. It's been discussedon a dozen forums. It first came to life on the Practical Machinist websiteand you can easily find Dave Kemp's email and chat with him directly aboutit.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Wing border

Look at 43:13 and any covering manual I have ever seen. They all show ways to cover ends and say it is required.

Looking quickly (emphasis on "quickly") through Section 2 (fabric covering) ofAC 43.13-1B, I didn't see anything that said that wing butts must be covered,but I did find a reference to the manner in which overlapped and doped seamsshould be dealt with for wing butts. So, they do tell you what you should doIF you cover the wing butts with an overlapped and doped seam. I have attacheda copy of the pertinent section.I think the main concern would be ensuring that the fabric is securely attachedto the airframe, and that there is no chance that the fabric could come looseover time, and likely the easiest way to do that would be to cover the wing butts.Although, if built to the published plans for the 3-piece wing, the wingbutt will have a 2 inch wide plywood strip, which would provide a good amountof surface area for fabric adhesion.Bill C.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/4313 ... ___Subject: Pietenpol-List: Re: Wing border

Well.......time will tell if he has in fact copied my color scheme exactly. If so, then yes, he would be right on the mark there as well! Not that I necessarily approve of that behavior, but it would prove his good taste and his ability to copy important features of those who came before.Dan HelsperPuryear, TN-----Original Message-----

Original Posted By:ng about=2C and I certainly don't have to prove myself to anyone. Gene
I take it Dan's post was tongue in cheek. I have certainly never taken such a position. There are people on this post who are engineers=2C who are master machinists=2C who have spent their whole lives building=2C restoring and flying a myraid of aircraft=2C who are A&Ps and IAs - some for many=2C many years. Sometimes people from this group step in from time to time to offer their opinion=2C based on knowledge and experience=2C in areas they are familiar with. There are also those who are none of these things=2C but who nonetheless offer authoritative-sounding opinions on most anything regardless of whether they have any first-hand knowledge. Newcomers to this list have no way of knowing the difference. The standard retort from the peanut gallery to every single statement is that "this is an experimental airplane and I can do anything I want." True enough=2C but there are some general practices that can be changed=2C but for no reason. You don't HAVE to use locknuts or cotter pins in aircraft bolts . . . the books all say it=2C common sense dictates it=2C but it IS an experimental airplane. I doubt any inspector will approve it=2C but let me know how the experimental argument works for you. Primary flight control cables in (modern) certified airplanes are always at least 1/8 by rule. Yes=2C the plans show less=2C yes=2C you can do it=2C it IS an experimental airplane. Do whatever you want. There are a million other standard ppractices that are ignored on this list every day by people who don't want to listen to experience. Since it seems to bother so many people to have their certainty threatened by anyone who just might know what they are talking about=2C I will wisely join the majority of the people in the first paragraph and keep my mouth shut from now on by removing myself from this list. God forbid I might know what I am talki

Ryan,I have only successfully completed one Pietenpol, and no way consider myselfto be all-knowing.but, FWIW.I don't think your weight will be an issue. Do not move your cockpit.it willlead to too many issues. Consider allowing your wing to tilt back 4" (that'swhat I did. I'm 195 when I'm lying). I have a wing tank, and fuel andpassenger seem to do very little to the balance, although it does affect theweight, and therefore the performance. You did not mention your engine,although I have witnessed Model A's doing amazing work at Brodhead. I have aCorvair, developing 110 hp on T/O, with my current prop.Please keep us posted on your progress!Gary BootheNX308MB

I've never researched one of those, but hear A LOT about them on many welding forums.It's one of those things where you hate to admit it, but apparantly theywork really really well... especially in the not so heavy duty cycle/occassionaluse arena (which is us).ESPECIALLY with ALL the accessories there, including a helmet. One stop shoppingand everything is matched. Maybe with the exception of a little dedicatedgrinder to keep your tungsten sharp. By the way, when learning TIG, you're gonna contaminate your tungsten a lot. Juststop, regrind and go again. Trying to weld with a messed up tip is completelycounterproductive. It's tough to make yourself stop, especially when youget a good run going, but you can't. Ultimately gonna frustrate you more thanjust stopping to reset.By the way, for anyone learning welding, I HIGHLY recommend paying a visit to www.weldingtipsandtricks.com. That guy makes some REALLY easy to watch and understand videos of all sorts of welding. It's a great website. Nothing but really practical videos and advice.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Re: Pietenpol-List: Am I building the wrong airplane?

Thanks. Haven't decided on engine yet but it's either Corvair or Continental. Since I can't decide I'm focusing on fire wall aft.
