    Jeff, I have been to all the Piet fly-ins since the conception, and I do not intend to miss the next , Of course it all depends on ,will I still be kicking the rudder bar. My track record is being marred by extenuating circumstances. Would you like to take an introductory course in added Ford power? She doesn't snap your head back, with two people but she goes well. Not like my Werner 145 and there are a good number of more powerful engines on Piets. But the Ford is still doing it's job since 1989, with no problems, except a bent prop and crank extension. We ( Blue Piet ) and Lowell are looking forward to seeing all the group this coming summer.

    Subject: considering a concept
    Having picked up my parts and such and thinking about my engine assembly I was also thinking about suction /vacuum sources? Pump, venturi or, here comes the brainstorm idea....... like in automotive, tap the engine vacuum from the intake side. Does anyone have any experience in doing that on a Lycoming engine? I would be curious about anyone's experience in trying that to operate vac instruments. Any ideas on how that may impact engine performance with what will appear to the engine as a vacuum leak on the intake side. Obviously I am just exploring an idea here and have not committed to anything on this but was curious about the concept. Conceivable one could operate all sorts of vacuum controls for airflow, heat, vents similar to a car using the same control block and parts to open and close dampers or other devices. rubber hose is much lighter and flexible than steel cable dampers. Okay, what say you group? Thanks John

    Subject: considering a concept
    What vacuum device does a Pietenpol need, other than possibly a Turn and Bank indicator? I have a T&B on mine, powered by a venturi on the belly. Works great, and has come in handy a couple of times when weather deteriorated suddenly (like last Sunday, leaving Sun 'n' Fun). Automobiles used to use vacuum powered windshield wipers. I remember how frustrating it was when driving in the rain, behind a slow truck. When you'd get a chance to pass, and floored the accelerator the windshield wipers would nearly stop, because there wasn't enough vacuum at wide open throttle to power them, so you were passing a truck with all the spray it was throwing, and you had no wiper action. Since airplanes operate at or close to WOT most of the time, I doubt you'd have enough vacuum to reliably power much. You need 4" to 6" of vacuum for most instruments.

    Subject: Re: was considering a concept-- now vacuum power
    Venturi work well and have few downsides, I'd stick with them-- why mess with your engine-- something else to go wrong. The added drag of an external fixture on a very draggy Piet is minimal. As to using vacuum to operate things, there is a thought. Hard plastic airline hose is strong and light, and easy to run. I used to do fluid power, mostly air, some hydraulic, never vacuum. What pressure differential do we see-- what psi? If this is practical, I would be thinking of tiny air valves and cylinders-- Festo or Clippard-- if they still exist. OTOH, this might be better on a more complicated craft-- I have a PGK-1 in mind.

I almost made it up there several days ago. Made it up to Burlington to see if Rob was around, chatted with Fred Wright a bit and got a tour of his *amazing* Stearman and L-5 collection. By the time I decided Rob wasn't around I decided that it was getting late and needed to head home. I'll make it up there sometime soon, though.

    Can't speak for anyone else, but I'd say, KISS. David Paule P.S. "Keep It Simple, Stupid," is a well-known engineering rule. Frequently violated at significant cost and schedule impact, and it has been learned that there's usually a performance cost as well. Since you can at best achieve only two of these attributes, Good, Fast and Cheap, or if you wish to be corporate, Performance, Schedule and Cost, try very hard not to fail at them all. ----- Having picked up my parts and such and thinking about my engine assembly I was also thinking about suction /vacuum sources?

    I had one on a 1968 Harley Sportster. Kick start only. It was good in that application. It was a magneto system with no battery. Similar to our Piets in that respect. Jeff Wilson N899WT

I realized that today and thought I should try to make up for that so I put together a short chronicle of my build since February of 2007 when I first began the build process. Naturally that did not begin immediately since I too ordered the prints, sat on them of a few months contemplating just how to begin. I had the good fortune to let a friend both convince and help me get started. He convinced me that I had the skills and just lacked the confidence to begin. From the time I got the prints I traveled and visited other builders and got some really good advice, the same tha I pass on to others making sure I give credit to the person I first herad it from. I posted my album on facebook and immediately received some ratherflattering comments, which I never expected. I though that for what ever reason those of you not on facebook may also be interested to see some of my progress pics. Actually since I have not made any of the pub;ic in the past and have only talked about building I figured it was time to lend some crdability to my claims and share some with those of you who have been more than willing to share their pictures. I hope you find them suitable and worthy of your time and enjoy looking at them as much as I have in building them. You should note that the pictures of the laminates were take by their skilled craftsman Dennis Vanderweide,who I am proud and privlidged to call my friend, mentor and convincer of the notion that I too can build a Pietenpol. Without whom I would still be lurking, wondering, wanting and dreaming of building my own Pietenpol while looking at the prints and never doing anything about it.
