I chose to assemble my wheels all myself and man what nightmare. Ended up lacing and truing them two times each, and re-lacing one again after that. I have gotten quite good at it now, one wheel only takes me about 2 hours from start to finish. Mounting the first tire took 3 1/2 hours and three tubes and the last only took 1/2 hour and one tube. Tip, do not use tire irons, use a rope two hands and a foot. Throw in the large amount of money I have invested in these wheels and I am really hating these things right now. I know I will change my mind eventually but right now they are in the dog house! Sorry to vent, but MAN this building thing really stinks some times.

There is a vertical tube behind the engine. It runs directly behind the chafe tape w/ zip-tie that is on the angled engine mount member. This would appear to me to be part of the intake manifold. As I follow it down I see it steps down in size, and then I can just make out what appears to be the carb flange, mostly hidden behind the horizontal engine mount member. The manual instructions say that the manifold is made of 1 1/2" OD steel tubing, and the jacket is made from 2" tubing. After viewing this pic, and reading that description again, my initial conclusion would be that he slipped the 2" tubing over the 1 1/2" tubing, cut circular "caps" to enclose the ends of the 2" tubing, and welded this all together. I would then guess that he would run oil through a fitting into and out of the jacket. I can barely make out what appears to be an oil line attaching to the top of the jacket on the side facing the camera, and another line running behind the jacket in roughly the same location. This all raises another question: would he run warm oil into, and take cool oil out of fittings that are both located at the top of the jacket? After the jacket is filled with oil I would think this would not promote circulation of the oil through the jacket long enough to do any good. In addition, why would those three copper tubing lines, assuming they are oil lines, need to be run to the firewall like that? I hope I'm not missing something completely obvious here. Any thoughts on the matter would be appreciated.

I do have a copy of the manual (borrowed from a friend to thumb through before I take it back when I go to pick up my core from him in two weeks). I'll order my own copy (and see how long it takes to show up) before we order parts, as I'll need to send in the disclaimer from the manual. We will follow his minimum recommendations for many aspects of the rebuild (forged pistons, ARP rod bolts, etc). I imagine we will buy a few parts from him, such as the oil pan, maybe the safety shaft. We're building a hand-prop motor, so we won't need his starter setup. I plan on keeping the alternator in the rear, so we won't need the brackets. Because we won't be using a front alternator, we have no need for the gold hub w/ the pulley groove that he sells. If I'm not going to need use the front pulley, then I do not want the prop hub being any longer than necessary (no need adding extra stress on the crank), so we'll stick to the Pietenpol design there as well. We'll fab our own exhaust, so on an so forth. I have been lurking for a bit on the Corvaircraft mailing list, and it is a very active and interesting source of information and opinion.

Mike Cuy and Chuck Gantzer both mention this in their videos and point out various locations where it makes a big difference in being able to fit bolts through the fittings and to work with the nuts on them. Parts like the wing strut attach fittings that stick out the bottom of the wings, if made to plans, put the attachment hardware right up against the fabric covering with no room to work.

That means edges are harder and less prone to wear at the edge which could be a positive note when considering holes would be treated to prevent wear. Areas where hardened edges are not wanted or warranted can always be ground or filed off as I suspect the heat would be concentrated and localized to a small area which can be ground or filed off as needed. Not unless I am missing some critical piece of information, in which case please advise, (Piet Builder in training and learning new things daily). I think, I would prefer to file a little than cut a bunch, just my uneducated opinion for today and subject to change based upon a more pragmatic and empirical approach.

Do you plan on never flying off of a paved runway? Brian, I've got quite a few hours logged with a tail skid...around 50 or 60 hrs. Very noisy, though...sounds like you're dragging a pop machine across rough concrete !! Over half of those hours was without brakes. During the first half of '03 I installed brakes, and flew to Brodhead / Oshkosh with the hydraulic heel brakes, and a tailskid. Take off on hard surface isn't too difficult in light wind conditions, because the rudder becomes effective as soon as some prop wash flows over the rudder. Landing on a hard surface with a tail skid is a totally different story. Not much propwash during the landing phase. Difficult to control the roll out with the brakes, because it kept tending to lift the tail back up each time I stabbed one of the heel brakes, to keep it straight. Two times, I ran off of a runway while landing (missing the runway lights) during that cross country trip from Wichita KS to Brodhead / Oshkosh. One of those landings was a pretty stiff crosswind. Taxiing on hard surface with a tailskid is difficult, at best, with any wind at all. However, keep the tailskid on the grass, and it poses no problem at all during taxi, on take off, or landing...with or without brakes...just gotta stay ahead of the plane !! Chuck G.

One of the things in the process I was wondering about was the design of the intake manifold. Bernard indicates that the intake manifold is jacketed, and engine oil is circulated through it in order to heat the manifold, and cool the oil. If it's not an utter bear to construct, it would seem to be a good way to heat the manifold to reduce the susceptibility to carb ice. > > Unfortunately there is no picture or drawing of this that I have found, and I do not know exactly how one would go about fabricating such a setup. Might anyone have an eye-witness description in a bit more detail, or better yet some photos? I wish we had been able to pop the cowling on the "Last Original" at Brodhead, but we didn't ask at the time because we did not want to be a bother with everything else that was going on. Maybe on the next trip up. > > Have a good evening everyone, > > Ryan > > > Read this topic online here: > > http://forums.matronics.com/viewtopic.php?p=133851#133851 > > ________________________________ Message 23 ____________________________________ Time: 05:58:34 PM PST US From: "Chet's Mail" Subject: Re: Pietenpol-List: High Speed Taxi Dick, I have the same setup as you discribe, so I'll look into this and make the proper adjustment. This make sence to me as what could be my problem. I also have the tail hook for securing the aircraft while starting with the release cable that is also conected to the left tail wheel cable. I might have a second problem there. I do thank you for your input.

But first, a basic rule with the Piet is that EVERYTHING makes a diffrence. I had rudder cables that went from the rudder bar to a point behind the seat where I had joined them to the tailwheel, a "Y". When I would taxi and lift the tail, the plane immediatly would veere to the left. This caused me to run off the runway a couple of times. I found that the tailwheel springs were storing energy and when the tail lifted, the rudder would shift. I replaced the cables with dual cables from the rudder bar, problem solved.

Do you have gap seals on your elevators? The wider the gap, the more the effect. When I first started flying mine, the tail was hard to get up and right wing wanted to raise as it was going off to the left. Try some duct tape on the elevator gaps, it may be a huge difference. I had a 3/4" gap.

Today I stopped in Sears and found a level with a digital read out to the tenth of a degree. It also has a laser. I was able to fine tune the wings and the $50 was well worth it. Also, I had final airworhyness inspection on friday and passed. I'm hoping for first flight this weekend.
