    Douwe, Can't wait to see her. This airplane I am sure will be one of the most beau tiful and unique ever to grace the skies over Brodhead. I for one will grea tly appreciate seeing it.

I especially appreciated Dan's ersonalized video!! Well, it has all helped light the fire under me for the big final push. go t the ngine pretty much hooked up and once I get the pesky oil pressure hardware in nd hooked up, and some prop bolts I can do an engine run!! Just want to run it while the fuse is bare so it's easy to fix any leaks or iring mistakes. I anticipate being ready to run it within three weeks. Then it's basically finishing all my little fixes and mods on the fuse, cov er he fuse and tail feathers, paint it and bolt her together!! I'm really going to aim for a first flight early summer.

    Subject: Re: Gear Question
    Gear QuestionJack, all the drawings I have seen use a longer bolt. Not being a metalurgist I can't help with the pin bit. You're probably going to cover the whole thing up with some sort of cover so why the reluctance with using the longer bolt? That would be so much simpler. C ----- Original Message ----- From: Jack To: pietenpol-list@matronics.com Sent: Saturday, February 25, 2012 7:36 PM Subject: Pietenpol-List: Gear Question Hello all hope you can help with a question. If you look at the attached picture you will see the bolt holding my gear spring assembly together is resting on the bolt head and nut. Should I use a longer bolt (rather not) so the stress is on the bolt shaft? Or fashion a pin with cotter keys on each end? If I do that should it be 4130 rod? I tried to cut the head off an AN bolt tonight and they are hard! If I do the pin, should I harden after cutting and drilling? Could it be soft steel? So many questions, thanks for your expertise!

    Subject: waterproofing hinges etc.
    From: Timothy Willis <timwillis01@gmail.com>
    Thanks for replies, esp. Hans. I will varnish all the screwholes as described, and put drain holes in the lower edges, corners, etc. And I will get a custom cockpit cover, even for my hangared plane. (I don't like scorpions.) I'll also look into alternative hinges for the flop. And I know not to fly in rain, and to get elsewhere or stuff under cover if it looks like rain. All good thoughts, thanks. I noticed at Brodhead in years back that some of you not only had custom canvas cockpit covers, but that virtually all of you had a simple plastic tarp over the wing as well. There was either heavy dew or rain drops on all of the top covers. Those good procedures still left the ailerons out in the weather. But 80 years of experience no doubt indicate that proper preparation works. "Be Prepared" goes beyond the Boy Scouts. In 2011 here we had the worst drought in our history, but not long before our stretch of under 5 inches of rain in 15 months, we had over 15 inches of rain in 24 hours. Nothing was dry for a week or more. BTW drought is expected here again in 2012. Thanks, Tim in central TX do not archive

I really love these small Continentals and they continue to serve experimenters (and certified aircraft manufacturers as well, in the O200), long after their designers could have dreamed that they would. As I wrote in my article about them in Contact! magazine, they are reliable, simple, and straightforward engines but they do have their quirks and weaknesses. I'm no expert on engines in general, but I would have to agree with what one writer said about the earliest of the genre, the A45, when he stated that it may be one of the simplest 4-stroke engines ever devised.

    Hey Douwe, my motivation was completely selfish - I want a ride in your plane when it's done! Well, that and to fly "formation" with you around Brodhead, too. I reckon you'll be the only one that can keep up with me with the mighty C-90 you'll have. :-D Cheers! Dan do not archive

    Subject: New Carb
    From: "bender" <jfaith@solairusaviation.com>
    So i found a new carb for my A.. i had a tillotson and was having a little trouble stating it and getting it down to a good idle. I found some info on new model Zenith carbs and starting looking for one of two or three models. I picked up a new in the box Zenith 14995.. it has a better idle circuit from what i understand and better float.. there are 3 fuel ports..one on the back and one on each side..and the linkage can be attached on either side.. comes with nice linkage arms too.. only took three blade and it fired right up.. way rich at first but a simple adjustment and it was purring at 600rpm .. i was seeing about 1900 at full throttle.. i think the carb was a good purchase. http://youtu.be/jWCVSiBuPxg did a little fabric work too.. jeff Read this topic online here: http://forums.matronics.com/viewtopic.php?p=367306#367306

    you are all right=2C of course=2C I spoke too quickly. From: pietflyr@bellsouth.net Subject: RE: Pietenpol-List: Engine Push Rod Length Sorry for piling on=2C Gene. I responded before seeing how many people had already responded. I must admit=2C when I rebuilt my A65 I was somewhat astonished at the level of sophistication the little engine has. Prior to assembling that engine=2C I would have assumed it had mechancial l ifters as well (it certainly has enough of that old =93Continental Clatter=94 to have solid lifters like a Volkswagon). I well remember checking all 8 valve lifter assemblies for proper leak down time before assembling my engi ne. Those =93Zero Lash=94 lifters are what allows such a wide range of clearance between the valve stem and the rocker arm=2C and all that data ca me straight from the Continental overhaul manual. You may have been thinking about the 65 Lycoming. I don=92t know if its lifters were solid or hydraulic=2C because I=92ve never taken one of those apart.

Gene do not archive From: pietflyr@bellsouth.net Subject: RE: Pietenpol-List: Engine Push Rod Length Michael=2C that expensive overhaul manual you bought should have a Table of Limits in it. You=92ll find the information you need there. >From looking at mine=2C I find that the pushrods (new) should have a length of 10.797=94 to 10.827=94. The serviceable limit length is 10.785=94 To determine if you need the oversize pushrods=2C you will have to have the engine assembled=2C and measure the c learance between the valve stem and the rocker arm=2C with the hydraulic lifter full y deflated. The clearance is supposed to be between 0.030=94 and 0.110=94. If your clearance is more than 0.110=94 you will need the longer pushrod.

    Way cool Jeff. Sounds really nice and smooth (better than mine). That Zenit h carb, it is new?, or a newer version of an old carb? That 1900 RPM static I think is very good. Mine is 1860. Also, looks as though we may yet have another Black and Yellow German comin g down the line?..... Gene Rambo, you better hurry or you will be #3.

    To clarify, that would be the A-40. Chet Peek, author of the excellent "The Pietenpol Story". He has also written a nice history of the A-40 entitled "Flying on 40 Horses".

    it is a new carb.. its made for industrial applications.. they have a replacement for the model a pn 13922 but i found this site.. http://clubs.hemmings.com/clubsites/durant/Tech/ZENITHcarinfo.htm that explained some sizes.. and the model b ford garage site that showed sizes of original zenith carbs.. the 14995 has a little bigger venturi but the bore where it mounts is the same as the A carb.. same bolt holes too. i found mine after a little searching on ebay.. but their is a site that has them for sale... i'll dig it up the new ones are lighter... aluminum..i think and after the easy start and adjustment i had today i'm sold I found mine for $175.... the other place i found had them for about 100 more Dan my prop has less bite than yours.. 76-42 so maybe thats why i see more rpm.. And the color... its Charleston green.... really dark.. but not black ...its pretty close to the engine green on an A and the tan is close to another model a car color I'm not gonna be blamed for stealing paint jobs jeff Read this topic online here: http://forums.matronics.com/viewtopic.php?p=367332#367332
