Got a question about Exhaust pipes. We are ready to start work on the cowling and need pipes to do it. I have a nose wheel and a 4 into one doesn't look like the way to go. I would like a 2 into 2 . Is there a good one on the market or do I try to make one? I've seen RevMasters and it looks great but they seem to like it a lot. Something out there I've missed? Also.

A phone call to Dan Diehl and describing how I was losing charging once the plane got hot (engine temp at 190 degrees normal), got a question from Dan as to where the regulator was located. I told him on the firewall. He said that the regulator during use gets too hot to touch, and he felt that it was failing out due to too much heat, which is something I have witnessed in cars; too much heat too many times and the diodes that collapse to control voltage in the regulator collapse due to heat not voltage, and don't reset. I borrowed the tube from the battery cooling, and relocated to the regulator, and bingo! no more problem. You can also relocate the regulator to the cooling baffle right behind the left hand head, to allow good cooling that way, which is what Dan recommended. Internal regulated alternators due this by having their own fan mounted on the shaft right behind the pulley, so it makes perfect sense. In reference to the loss of control, please all keep in mind that in DOES NOT have to do with a problem with the KR2 design or improper control deflection of the plane. The FAA categorizes the various levels of windshear, based on whether the pilot loses temporary control of the aircraft, and if so by how much for how long. More detailed explanations are available in advisory circulars you can download for free from either AOPA, or EAA, or the FAA website. Briefly, mild turbulence is that which causes the aircraft to move around, but does not cause the loss of any directional control surface. This is what we mostly feel, even if it moves the plane in a direction we don't want it to go, we can bring it back to level flight. Too many pilots report this as moderate turbulence. Moderate turbulence is that which causes the momentary loss of directional control of the aircraft. This is when you experience what I had yesterday, which is turbulence that causes a change in direction in the plane, and even with full control inputs, continues in that direction, or combinations of directions. It occurs briefly, 5-30 seconds at a time and then full control is restored afterwards. Severe turbulence is that which causes total loss of control and lasts much longer than moderate, and can include aircraft damage, either from pilot inputs to regain control, or simply violent response from the aircraft. This would similar to getting caught in large aircraft wake turbulence. What I had was mild to moderate turbulence, and it was at the same altitudes virtually all day, approximately 1000' MSL to 2500' MSL (mean sea level). Above and below just fine. The trick is being willing to be patient, and ride out the airplane's response to the turbulence, and not tear it up trying to fight the windshear, but rather go with it, and then as soon as you are out of it, maneuver back to level flight. It would actually be pretty fun, if it weren't so dog gone violent in the way it surprises you, and the rapid change in direction without warning. I think my head hit the canopy roof 3 times yesterday! And I am only 5'5", wearing a 4 way harness! BUT...like the great bird she is, the KR just kept coming back for more. Even with the strong winds, and bumpy conditions I had no trouble making 3 squeaker landings (don't ask how I know not to add alot of brakes when the tail is still up). I also found out that my left arm will freeze without a jacket on, while the rest of me is fine due to body heat warming the cockpit. That wonderful vent for the summer does NOT completely seal when closed. 47 degrees at sea level is MUCH colder at 5500' ! Now, if I could just get the CD player working.... 22.2 hours and counting. Off to the airport....

At the time I bought the 175, the Lincoln was the better choice between it and the Miller, for what I was doing. Miller has also come out with new models, so like Brian said, check them both out (online opinions, maybe), and then buy it at SNF or OSH. I know Lincoln sells them at those two shows at dealer cost, so you can't buy it anywhere else cheaper, and they will indeed ship it free to your house. That's the way I got mine. I welded with it for about 2 minutes and said "I've gotta have one", because up until then, I'd tried to weld for months with no sucess, but all of the sudden I was doing nice beads that I could live with. I then signed up for the Sportair TIG welding course, and had one of the best 4130 welders in the world to tell me that my welding was good enough for aircraft work, so I think I'm good to go. (See some details on our class at http://home.hiwaay.net/~langford/sportair/ ). I suspect the reason that you don't see Square Wave 175's on ebay is because not that many welders are dying...which is the only way most 175 owners would part with theirs! I had the chance to work on my airbox last weekend, and fired up the welder 10-12 times to tack little pieces of aluminum, 4130, and stainless together. I didn't know how much I needed it until I got it, and now I look at fabrication in an entirely different way...

There are things I'll do differently on the next go 'round, but I can fly with this one until then. Shockingly, it's made out of aluminum, rather than glass, but I figured it would be a lot easier to get the valves to work smoothly, since they would be based on flat surfaces with bent-up aluminum.. It turns out, the way I did it could have just as easily been glass. Ram air valve is a 3/16" diameter 4130 rod with stainless flapper plate welded to it, and carb heat valve is a long AN3 bolt with another flapper welded to it, all with O*lite bushings. Carb heat valve and ram air valve are both cable actuated, but next time I'll make the carb heat a weighted affair, so when ram air is on, carb heat will be off because the ram pressure and a little more weight will force it closed (it's on sintered bearings and flops around nicely), and when ram air is off, carb heat will automatically be on because the engine is sucking on it. I think it would work that way now, if I didn't have a cable connected to it, but I could tweak the design to make sure it worked as expected. I get smarter after I build something that's almost right! The next one will be about an inch narrower too. This one is way too tight all the way around, requiring several miracles to make it work just right. For testing I won't even hook up the ram air, but will suck warm air from inside the cowling, with the option of really hot air from the heat muff, which is nothing more than some .025" aluminum rolled up and safety wired to the header, with a piece of homemade 304SS spring underneath. I hesitate to actually look, but I suspect my builder's log shows well over a hundred hours in the fabrication of this thing. I'll do a proper description of it later, after I'm flying. See the photo at http://home.hiwaay.net/~langford/corvair/airbox.jpg . So now I only have forty EIGHT things on my to-do-list before I fly, so don't even ask...
