So Ryan,2 (or 12) positive posts are too much and not very interesting, but 'water coolerguard' posts are better? I definitely disagree.This forum is much better served by the former than the latter.--------Semper Fi,Terry HandAthens, GARead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Southeast piet builders.

Not sure if this is really the kind of thing most people here would be interestedin, but considering I'm sure there's quite a few readers that don't post alot,thought I'd pass it along.A few years ago I hosted an 'event' for guys in the southeast that restore anduse old american made wood working machines. As a group (like this one, basicallyactive members of an internet forum, no formal 'membership' or anything),we have a big get together each year in Illinois. However, you have to get ahotel, there's a banquet and it's based at a museum, so there's a fee, it canget expensive. However, lots of eye candy and we'd arrange "demos" for someof the sorts of things that group does, that isn't very easy to learn on yourown (pouring babbit, etc), there was a small informal swap meet and loading equipmentso people could bring machines for other people (ie help with shippingbasically).To make mine different, I focused on making it a practical event. Bring a project,find someone to help you, use my machines and get something done you mightotherwise have to hire out. Machining rough castings for a machine restore,making parts (missing left hand threaded elevation screws), brazing broke castiron parts back together, we actually even cast some aluminum parts (belt sanderidler wheels), etc. I just let everyone crash where they may. Couches,air mattresses, motorhome, a few friends offered bedrooms. We just ate on theproperty, passed the hat, went into town and got meat, fired up the grill. I'm doing it again, kind of... Folks have been pestering me to do it again, butI'm desparate to get my hangar and new shop up before I do. It's been a superrainy winter so haven't made the progress I intended. So, since folks justwant a reason to get together, I decided to make it a hangar raising, but anyoneto wants to play with stuff, or arrange their own demos, that's fine. I figure a dozen guys can remove the tin and trusses from a nearby chicken houseI've been given, easier than just me and my son. I don't want people to comeand just work, just pitch in a little here and there if you don't mind.Insofar as airplane builders, I've got all the woodworking machinery you couldwant to build a plane, feel free to bring your spars, wing rib stock, whatever,and mill yourself up whatever you need. You can also play around with gas and tig welding. I've got a machine shop as well if you need parts milled, or just want some helplearning how to use a lathe or mill. If someone wants to make up a jig forgeneral use amongst the group, that would be fine. There's small private grass strips within a couple miles, you can fly in. I'llhave an A&P(IA) (he owns one of the strips) around if you need some help or advice.He's finishing up a Cub right now. If you fly in and need a car to getaround, no problems. Plenty of room to camp, crash in the house, whatever orwhere ever. There's hotels within a few miles too.If there's enough airplane people, we'll work on my Piet. Also have a steel tubePiet like homebuilt project we can mess around with. Need to reverse engineera wing rib jig for that as well. Even have a couple Model a blocks we couldclean up, bore cylinders, whatever. Bring along whatever project you haveand want some help with. Get everyone going, a wing would be ribstitched in aday. Don't know if Dick N got a project lined up for sun and fun, but if you need toget it to him, I think I'm along his travel path to there, it could be stagedhere (I'll have room if we get a hangar up!).

Your work really looks good! Let me tell you of some of the modifications wemade to the Big Piets. We found right away that having the eyebrow attachedwith the top cover screws was going to be a big problem. Every time you needto get to a spark plug, all the bolts have to come out and that is aninvitation for leaks around the top cover. We very quickly modified thebrows to Fig. #1 where the bent alum stays on the engine and the top coverbolts are never messed with. We thought this would be the solution, but withall the stuff that ends up on top of the engine (depending on yourconfiguration) like starter, alternator, oil filler etc., etc The sheetmetal screws become almost impossible to remove and replace. I bought pianohinge material and the next time the eyebrows come off, we will installpiano hinges with the removable center wire that will pull out toward thefront. Fig #2. This will make checking your spark plugs a 3 minute affairinstead of a 4 hour ordeal.My 2 centsBarry DavisNX973BPI attached a sketch but if you have a question just call me 1-888-834-8900-----Original Message-----

OK, Tom. I will be using a Corvair engine which turns the 'wrong' way. I plan to offset the vertical fin to counteract the torque. As I understand it, the 'real' engine builders are off setting the fin -- front of fin -- to the right. I guess I will have to offset mine to the left. Correct? Seems that it should be the other way around. Chuck----- Original Message -----

When I first started flying Helicopters I some times pushed the wrong pedal when adding power. In an airplane with a left turning prop, you have to add right rudder when adding power. In a helio the rotor turns clockwise and you have to add left pedal when adding power -- like when you're adding power to come to a hover from the ground. After a while it became natural for me.
