    I like my early 40's Allis Chalmers B with a finish mower. Used it for twelve years and literally did nothing but add oil, gas and sharpen the blades a couple times. You can get them from about $250 to a grand. New machines are hinky when it comes to the carbs, sitting, and auto gas, especially with ethanol. Just another perspective!

    Semih; I'm going to be 66 in a few months so I'm not far behind you, and my prediction is that your 5/8" vertical stabilizer offset will be pretty good, but not perfect. And I not only remember trig, I actually use it and enjoy it in my engineering work There is a link between science, mathematics, and philosophy that trigonometry captures. Those who know and understand the mathematical constant pi know what I mean. The perfection of a circle is described mathematically (and trigonometrically) by pi- and yet pi is an irrational number that cannot be quantified as a fraction, its decimal digits never repeat into infinity, it is not the root of any non-zero polynomial, and as such it is a transcendental number- but even the beginning student can grasp how it perfectly, exactly, describes the ratio of a circle's circumference to its diameter. By the use of this relationship we understand everything from astrophysics to geolocation to how to divide a pizza into equal parts even if there are an odd number of people to be served ;o) Good for you, Oldbird! -------- Oscar Zuniga Medford, OR Air Camper NX41CC &quot;Scout&quot; A75 power, 72x36 Culver prop Read this topic online here: http://forums.matronics.com/viewtopic.php?p=465320#465320

    Subject: Re: Long fuselage and Model A
    From: "taildrags" <taildrags@hotmail.com>
    Jerry; to answer your question, I have not done this so, my comments are general only. My airplane has a Continental A75 up front. The original Air Camper had the water-cooled Ford "A" engine up front and had the shortest length fuselage of the common variants. Many have noted that more modern Air Campers have tended to be tail-heavy, and no doubt some of that is due to extending the fuselage aft of the firewall by stretching the cockpits or extending the empennage. You say you are rebuilding a long-fuse Piet, so are you actually reworking the fuselage or are you just thinking about the motor mounts and things that are ahead of the firewall? I think your starting point should be to research what the weight of the conventional Ford "A" engine conversion is, including radiator and coolant system, and use that as your basis for comparison. It sounds like you may want to keep your firewall-forward package at least as heavy as the original, and think about where it's going to mount. The standard Air Camper has cabane struts that pivot at both ends, which allows the wing to be shifted aft to correct (or adjust) an aft CG, but only within limits. -------- Oscar Zuniga Medford, OR Air Camper NX41CC &quot;Scout&quot; A75 power, 72x36 Culver prop Read this topic online here: http://forums.matronics.com/viewtopic.php?p=465321#465321

    Chuck: the reason I didn't want to mess with moving or fabricating new rear L-brackets for the aft edge of the vertical stabilizer was "laziness" ;o) Yes, I could do that and accommodate another 1.4 degrees of twist without worrying about the wood spar. I know you think that slight angle of rotation sounds insignificant, but when you push the leading edge of the VS over and watch the rear spar stay fixed as everything else tightens up, you start thinking about the glue joints and everything else, and I didn't like the feeling as I pushed it over past the 1/2" that I gave it. By the way, the builder of my Piet, Corky Corbett, will also be 93 this year (I believe)- but he completed and flew NX41CC as a much younger man than you... he was only 80 ;o) -------- Oscar Zuniga Medford, OR Air Camper NX41CC &quot;Scout&quot; A75 power, 72x36 Culver prop Read this topic online here: http://forums.matronics.com/viewtopic.php?p=465322#465322

    Steve: since we're off-topic here, I can guarantee you that you will be almost as proud of a refurbished yard machine as you will of an airplane. I have rescued "this thing's broken and no good anymore" lawn equipment, appliances, electronics, engines, and all sorts of other things and have greatly enjoyed dismantling them, cleaning, repairing, refurbishing, and getting them operational again. A co-worker had a relatively new lawn mower that wouldn't start. Hmmm... crankcase was full of a gas-oil mixture. Now, how did that happen? At first I blamed him, thinking that he poured the gasoline right into the oil filler, but that wasn't it. I figured it out ;o) He was ready to take the machine to the dump, now it starts and runs like a top and I'm very pleased at the overall appearance and operation after a weekend of tinkering, cleaning, and getting it fixed again. Sure, it's a $150 machine brand-new and I spent probably four times that amount of my time on it, but it was enjoyable and rewarding. I'm with the others who made similar recommendations... find yourself a restorable mower and have some fun getting it running again. -------- Oscar Zuniga Medford, OR Air Camper NX41CC &quot;Scout&quot; A75 power, 72x36 Culver prop Read this topic online here: http://forums.matronics.com/viewtopic.php?p=465323#465323

    Subject: Con job on Craigslist OT
    Wow, I was just nibbling at the edge of a con. There was a Craigslist offer of a small 2008 John Deere tractor for $2000. A small tractor bigger than the garden tractors. Looked great, when I asked what accessories come with it. I got an answer that said everything in the photos. Mower deck, front end loader, Snow plow, and forklift. But the individual was in pre deployment training at Offutt AFB and could not meet anyone before deploying. I should email my name, phone number and whole address so they could tell eBay I was the buyer. Then they would be put it in the eBay money back guarantee program. It would be shipped by the Military Logistic Department, free no less. I could not check it out since this department already had it in storage. The hair on my back stood up.(I am bald). First in the military, it is always logistics, never Logistic. I have deployed multiple times and supported units deploying. I have never heard of the military shipping a vehicle to a third party. Much less free. So I checked out eBay policy and they don't guarantee vehicles. A Google search of military logistic department brought up a list of scams using this term. Usually they are selling a car or truck. Y'all be careful out there. BTW there are some good deals out there on Craigslist that I can see before I buy! Blue skies, Steve D

    Ah Oscar, too many projects. Moving into a new home and hangar. Beech annual that is owner hindered. Selling a travel trailer.finishing a pietenpol restoration. Renting the old hangar Preparing the new hangar to hold our old airstream and the v-tail and the piet. Oh yeah teaching the teen to drive. And in my free time I am working on my commercial and CFI ratings. I think I just need a good RUNNING mower.

    Oscar I built a stainless motor mount and built in about 2.5 degrees of right thrust. VS offset=8B will still be there. The mount is just a first t rial. I will measure the real angles (there is also some downthrust) and decide whether to use it. I am also interested in astrophysics and quantum physics. Just other hobbies. Keeps brain muscles going.
