I am guessing not, but I don't know. Alternatively, ShopNotes magazine suggests a two pass method to reduce/elminate splintering. Raise the table saw blade just enough to cut through one ply only on the first pass. Then raise it to cut through the material on the second pass.

This must be an urgent question about the Corvair, since you went with two(!) question marks. :) Grab a cup of coffee or three and start reading through all the information at http://www.flycorvair.com. That will keep you occupied for a while, and is the best source for Corvair information, parts, etc in the Corvaircraft community, IMO.

It was nice wx with light winds. I took her out and did some more taxiing all over the airport. Tooled down to Lon Deinst 's (builder of a perfect Art Chester "Jeep" replica that will be judged at Oshkosh this year) hangar and stopped to visit. I was telling him that I thought my water temp might be running a little high at 185 degrees. He called his son Eric who is a full time A & P and is actually the mechanic for that blue and white Model A Piet that is for sale over at Dekalb (IL) . I talked to Eric and he told me that the boys at Dekalb are experiencing 220 degrees water temp. So that made me feel a whole lot better about my situation. BTW Eric is also helping Dan (the man) Yocum with his sick cyl inder repair. After that, I started her back up (one pull) and continued on over toward the museum (Vintage Wings and Wheels) and grass runway 17- 35. Ran into Steve Thomas (infamous airport owner of Poplar Grove) and we stopped to chat and admire the Piet. He took my picture to include in the airport websight. Started her back up (took two pulls this time) and cont inued down to the end of the runway (wind was straight down the field) and gave her some gun. As I was accelerating, I thought I would try to lift off a little. Got about 3-4 ft. AGL, the wings started to pitch just slig htly, and I thought Oh yea, now I have to use these (ailerons). Chopped po wer and came down fine. Good test for the gear and bungee set-up. Repeated this whole procedure three times. It is funny but even with all my taildr agger time, I am still so apprehensive (don't say scared) about flying thi s ship, that I have put my heart and soul into for ten long years.

Only squawks that are materializing are that I am losing the little rubber pads that I put between the axle and the ash blocks (bottom member of the wood landing gear struts). So I am going to wrap a larger, piece of rubbe r around the axle, and then wrap the bungee cords over the top of that, so the rubber will be caught under the bungees.

A guy was installing rubber matting in the stalls and had quite a few scraps that he gave me. Some of the 'scraps' were 3' square, big enough to use as floor padding in my shop; others were considerably smaller. You can see in the attachments that this stuff is about 1/2" thick and very tough. Free for me is free for you, if you're interested. I haven't figured out an elegant way of finishing it, but I'm sure you can. Let me know if you are interested. BTW.3-4' off the ground counts as a TO, doesn't it? Gary Boothe Cool, Ca.

I usually climb it to at least 2500-3000' to play with stalls and it's always nice and cool up that high, so I don't know what it will do down low and hot but in controlled stall testing with power on, I can get the nose pointed VERY high up and hold it there with the ASI indicating down in ranges where it is obviously not accurate (in the low 30s, even high 20s, but with needle jumping due to buffet or propwash). If I hold 'er steady, the nose will not drop or bob, and it won't fall off to either side if I stay on the rudder. Just a steady mush. It takes a lot of nerve to hold the stick all the way back and power full on like that though. I have not tried it with the A75 yet... those experiences were with the 65.

Great to hear you're doing some crow hops. I found that actually flying the plane as you would your Aeronca Sedan on takeoff and landing is easier than the crow hops. Be prepared for a steeper approach in your Piet than your Sedan and much, much less float. I carried a bit more speed than needed for my first dozen or so landings so I could get the feel of the airplane in the flare and try to adjust my height accordingly. One of the biggest 1st Piet flight things that I wasn't expecting was how LOW you get in the buttocks to the ground to touch down compared to airplanes like your Sedan where you sit quite a bit higher in the saddle. Most first time Piet pilot landings tend to be about a foot off the ground where the pilot 'feels' like he is about to touch down. In the Piet you have to actually pretend that you're landing without a landing gear. Pretend like you're trying to grease on the belly of your airplane instead of the wheels and you'll be surprised at how good you do. My first few landings were 'drop-in's'. I didn't put rubber pads under my axle but let the ash bearer do it's thing and even after 12 years and many landings there's only a slight indentation where the axle hits.

Raising the blade 1/32" of an inch would be an incredible feat, though! I tossed the one gusset that got some adhesive stuck to it.

From: "kevinpurtee" Hi Joe Ive posted reports at 20, 50 and 100 hours which you may find helpful. Search the archives for kevinpurtee & youll find them. However, in summary, and in the order you asked: 1) NX899KP (corvair) burns 5.2 gph with just me and 5.8 gph at gross. My range is limited because I used the standard tank. Im ready to get out after 1:20 anyway. It climbs ~700 fpm at sea level at 75 degrees with just me. Not sure what the actual rate of climb is at gross but its darn sure better than a C-150 on a hot day. Cruise is 75 mph. CG is not an issue. I extended my engine mount an inch & moved the wing back 4 inches. My carb is a standard little airplane carb. I burn 100LL exclusively. 2) No, there are no standard setups for wire wheels. Look at west coast piet pictures for the various options. I bought my wheels from airdrome aeroplanes, the tires from JC Whitney, my brake disks from a motorcycle junk yard, and the brakes from a gokart place. At 115 hours & ~350 landings Im starting to pop spokes on the brake side of the hub. Suspect thats from the really good brakes. Im working through that. 3) NX899KP weighs 750 pounds empty and I set the gross at 1200. Its your choice.

From: "dgaldrich" Hi If you are seriously considering a Corvair as a power plant, PLEASE talk to William Wynne at flycorvair.com. Buy his conversion manual and read it cover to cover. He explains all the good and bad about it and is a character in and of himself, though he probably would disagree. His customer support is a thing of beauty if a bit unusual. If you can get to Brodhead, he'll be there along with a number of other people who have real actual time behind the engine in Piets. Talk to them to get ground truth and not anecdotal BS. It's not a perfect engine but I built one anyway. Sits on my bench ready to run as soon as I can get a stand.

From: "ldmill" Hi Dave, I've got a McCauley 70x38 metal prop. I've not benchmarked my tach rpm since I got the plane last month - should probably do so to confirm the reading. That being said, the plane performs quite well and I'm happy with it. I've not measured climb rate yet, will do so soon. I've wondered if maybe going to a 72x38 would gain anything - but don't want to spend the cash on a test that at best will have margin improvement I think.

I had the opportunity to prop the Last Original at Brodhead, and there we're talking a Bernard based conversion with hundreds of hours on it, not a tight new engine. It was a pain in the ass compared to the other engines you are likely to be propping on a Piet (i.e. small Continentals). I've propped a number of different kinds of engines in my time, and I would put the Corvair in on the "less favored" side. I suppose the closest analogue I've propped was a Continental O-300, another 6 cylinder. The Corvair's six cylinders make it more difficult to clearly find one coming up on compression, and when you swing the prop it is difficult to get it to turn that far at all before it grinds to a halt. Myself and another gentleman wore ourselves out on the Last Original before Tom Brown took mercy on us and showed up the proper technique. He stood in close to the prop and "choked up" on the blade, moving his hands down closer to the hub. By giving a good hearty swing with that technique he was able to get much greater rotation, and eventually got it started. Obviously the Corvair can be propped. Many have done it, and there are those that continue to do it with no problem. If they are comfortable with it, more power to them. When we were pursuing our Corvair I originally wanted a hand-prop engine, as that was more "old-school" and more aligned with what I felt a Piet should have. After having the chance to prop a Corvair I gave up on that notion: it is not something I would want to deal with every time I go flying. I want to say William Wynne wrote in his manual or on his website that he prefers starters on Corvairs because you can just calmly go about your business preparing to go flying, and when you are ready you just turn the key/push a button and you can start the engine. You will be in a more calm/focused/less agitated state of mind than if you had just spend 5 minutes at the prop getting a work out. You can argue that he is just trying to sell starter setups, but I think there is validity to his point. Have a good night!
