    Thanks everybody for the kind words! Mike, I am going to base it up the river a bit from Lee Bottom. Ck your charts for "Crawdaddy" right by Carrolton on the river. Beautiful little private strip, flat as can be with nice approaches and 3100' long!! ...and lots of flat fields around... I'll send a pic to Dan Helsper to post since I can't seem to post photos somehow. I'll wait until after inspection and then put the sheet metal back on so it kinda looks done. Douwe

    If one can find a Funk Al head, it gives a 6.25 : 1 compression. I milled mine to give a 7 : 1, Works on an A or B. My first A would just turn 1800,and installing the Funk head, before milling, it turned 2100 and hauled 2 people very easily.

    I've got one of those fancy aluminum dual plug Model A heads (got it in a box of engine parts I bought 5 years ago) just sitting on my shelf. If someone talks to Ken, let him know he's more than welcome to use it if he wants. Not interested in selling it but it will just sit there for (at LEAST) a few years. I would love to have someone actually use it rather than have it just sitting collecting dust.

    Hello All, Im bending the metal stabilizer attachment pieces using a small brake and getting good results. For my own piece of mind; should I have heated these when bending, or is cold bending (or the proper term) acceptable? I guess this applies to other pieces I will be making soon as well. Thanks, Steve Southern Maryland Read this topic online here: http://forums.matronics.com/viewtopic.php?p=284587#284587

    From: "dgaldrich" <dgaldrich@embarqmail.com>
    I already have the pile of 1/2 x 1/4 sticks and would love to have a jig. I had planned on using a 612 airfoil but would be amenable to the 613.5. Under that assumption that the Riblett airfoils are not protected by copyright/patent laws. I would think that a properly written release prior to sale would protect you from legal liabilities, especially in the experimental world. If you do get involved in the Type Certified biz, don't forget that Chief's/Champs also used wood ribs. Good luck in any event.

    Subject: Bending Metal
    Hi Steve They don't need to be heated but they should have a small radius to the bend to prevent cracking. Most metal brakes that I have used do not have a means of making a radius=2C they make a hard 90 degree bend which i s not good. If your brake doesn't make a hard bend then you're good to go.

    Steve, To prevent cracking while bending the parts, make sure the bend radius is at least 1 material thickness, and up to 3 thicknesses. When I bend thin sheet materials (less than .25 thk.), I generally use 1.5 to 2 thicknesses as the bend radius. BTW, when you cut the pieces, make sure the grain of the metal is perpendicular to the bend line. Bending parallel to the grain almost always causes cracking, and reduces the strength of the finished part. After bending, inspect with a loup to make sure no cracks have formed. If there are any, discard the piece, and remake it, using a larger bend radius. Any pieces that are going to be flight critical, i.e., cabane, engine & strut fitting, landing gear brackets, etc., should have all edges sanded smooth (almost polished) after bending. This will help prevent crack propogation from the edges of the piece. My company, KCS Development, is in the process of putting together a complete Pietenpol metal fitting kit, which will be manufactured using all of the above techniques, and more. Please feel free to contact me offline if I can be of assistance. Tom Kreiner -------- Tom Kreiner Read this topic online here: http://forums.matronics.com/viewtopic.php?p=284606#284606

    I found when squishing the ends of tubing for the rudder bar I would get cracks and poor looking ends when done cold. Heating to red and using a piece of 0.090 slipped into the end during the squish made a perfect looking end. If you dont already know Tony Bingelis has a series of good articles on making fittings. See Sport Aviation 9/1980, 10/1980 and 11/1980. These are also reprinted in one of his books; I think its the one with the blue cover. -------- Chris Sacramento, CA WestCoastPiet.com Read this topic online here: http://forums.matronics.com/viewtopic.php?p=284614#284614

    Great ideas. I tried to use a rounded piece of flat stock, but never thought of just filing the backing bar! I love this forum. Picture of first pieces attached, but I will look at with a loupe!

I asked, "Who in the world is Jake Schultz?", and was referred to an Amazon.com listing for the book he wrote about Molt Taylor, designer of the Aerocar, Coit amphibian, and Mini-Imp, just to name a few. This, of course, was of interest to me because I've long fancied the Imp as a unique aircraft. Anyway, in a subsequent email it was revealed to me that Jake is also building a Rotec radial powered Piet with a steel tube fuselage.
