Plan is to build it on the low budget system over the next mumble mumble years so it should be ready to get him a sport pilot license when he is old enough. Low budget because I am back in the poor college student phase of my life again adding an RN degree to what I already have. Secondary plan is to use it to show how all of this homeschool book learning stuff works in real life. Tertiary plan is to use it as a way to teach him to use all the fun toys in my harp, spinning wheel and medievil armor building shop. Matthew is now 10 and has been helping me in the shop for years. At first it was just, "Hand me that phillips screwdriver" type things but he learned the names off all the tools. At 8 it was drill press, catching boards coming out of the planer and power hand tools like the router. Last year at age 9 he got to turn some simple pieces on the metal lathe and started on the band saw. This year I will start on some of the other saws and let him make some things he can sell on ebay and at renassaince faires. I've been involved with the renassaince faire/SCA market for 25 years. That's me mentioned on the Argent Fox Harps webpage; www.argentfox.com/ We have lots of tools to play with. I noticed he's picked up 2 quotes from time spent together in the shop. "I do good work." and "Uh, don't tell mom." I noticed him using those expressions I normally use last spring while we were building a big carved wooden sign and a 2' illuminated clock that went with it. Our plane project is a Woodys Pusher not a Pietenpol. Similar in terms of speed and performance. The Woodys Pusher was designed in a time when a lot of builders did not have a shop full of tools so many of the parts were simplified. The Pietenpol is better designed in some ways so I am using bits of pieces, like truss wing ribs in my project. Gordon, can I buy a bit of that spruce next month? Woulda started buying wood this month but my tuition was due last week. Next year Matthew will be 12 by July and we planned to send him to EAA's aviation camp for a week. I know a great kid who can use a few of those Young Eagle points to help pay his tuition to camp if you know anyone with EAA Young Eagle points. DocFont, EAA 77755 yep, I think a 5 digit EAA number puts me in old timer, but not quite geezer status

    --> Pietenpol-List message posted by: Rick Holland <at7000ft@gmail.com> What size round 4130 tubing would be adequate for the cabane diagonal struts (to the top engine mount fitting)? I have some 3/4" .058 and some 1" .049 laying around. Also, is their a tubing strength comparison chart on line somewhere showing the different diameter/wall thickness sizes? Thanks -- Rick Holland

Flew it with the new engine installed today. I haven't carried a passenger yet, but the performance is improved dramatically. It's getting of the ground in the length of the turnaround at the end the runway. Might be 150ft. I'm not sure about the rate of climb, but I'm flying of a 1,200ft strip and the angle of climb improved a bunch too. I should be just fine with a normal sized passenger now. Should have done this a long time ago. Craig Lawler

    Subject: Re: Teen Builder
    --> Pietenpol-List message posted by: "Gordon Bowen" <gbowen@ptialaska.net> To support any Young Eagles or well motivated "teenbuilder" who has adequate motivation and supervision, I'll donate the wood currently in FL. It's all excellent 2 yr dryed Kachemak Bay AK Sika spruce. But- rough cut 8.5' max length (that's the length of my pickup bed), most 3/4" and some 1 1/2" thick, varies from 4" to 8" wide. Mostly knot free but some small tight knots. The problem for anyone interested is: 3-400 bf is in the hanger Palatka FL, you gotta get it yourself somehow. My co-builder of Piete N-1033B is at the airport everyday, contact Floyd at 386-325-3208, if you'd like to come and pickup some wood, just put it to the good use of building tomorrow's aviators. Each year around Nov. I come south from Homer AK and bring down some wood for friends that ask for it. It's all rough cut directly from the sawmill, but hand selected by one of the most environmentally smart and wood savey sawmillers I've ever had the pleasure go getting to know. It's excellent wood for homebuilders who what to make something meaningful. So, if any of you have good Young Eagles projects afoot and need wood, contact me prior to Nov. each year and I'll see what I can do to get it to you for least cost or free.

I had the skills to do something like this as a teen, but I think it would have been hard for me to see a project of this size through to the final product. I have a 14 year old whose only interest right now is to get this Corvair engine together and see it run. We put a long block together and then the Air Force sent me off to Flight Engineer school last week for the next six weeks. He's just itching for me to get back so we can wrench on it. Somewhere along the way I realized that we didn't orient the pistons properly and that we need to take it apart and flip half the pistons over. I was going to help him do it when I got back home. After reading your post and thinking about the things I was doing by myself when I was a young teen (building motors, doing bodywork, doing carpentry, plumbing and electrical work) I realized that I don't give him enough leeway to let him go and learn some of these things on his own. I'm always there supervising him and if he runs into trouble doing something I do it for him. As a result he doesn't have a lot of confidence in being able to accomplish anything on his own After thinking it over I called him and told him to go ahead and disassemble the motor and turn the pistons over. I know he can do it, it's just the matter of letting him do it on his own... -Mike McCarty mike after your first email it hit me that's how i treated my first son. it was hard to walk away sometimes and let him muddle through problems, but it worked out his 87 jaguar does a 13 second quarter mile and will top out at 175 mph on the road, only seen it once.but he did it all,and it gets 20 mpg.and you know hes a national champion competive trailrider ,and just took first at a national karate meet .so he turned out ok thanks for your emails

But beyond that, I am going to stick my neck waaaay out and ask why in the world build that nice fuselage mock-up only to discard it due to some of the wood grain slope being "out of spec"? It's fine to build a mock-up out of scrap for trying out different configurations of things, and it's fine to do it for the sheer practice and learning to build, but I don't believe I've every read anything that says the grain slope is critical for any reason other than to control twist/warpage due to changes in moisture content of the wood UNLESS we're talking about wing spars. For a truss structure like the fuselage, with short spans and everything cross-braced, grain slope as a factor leading to twist or warpage would not only be insignificant, it would have to all even itself out unless you intentionally aligned all the pieces with the grain in the same direction... not very likely with that many small pieces. There are differences in bending strength when comparing loading parallel or perpendicular to the grain, but for the fuselage structure where the loads are tension/compression, I don't see that it would make a bit of difference. If the stock is clear, knot-free, and has tight grain, I'd like to hear (for the purpose of my own education) why it wouldn't be suitable for the fuselage truss structure or even for the tail feathers (braced structures). I will say this about Douglas fir though... it's a pain to make holes in it when you're not drilling counter to the grain ("through the layers"). The layers of grain differ significantly in hardness and the "hard layers" grab your drill bit and offset the hole you're trying to drill if you don't use a guide or a short, stiff bit with the work held securely. Having built the entire structure of my "Flying Squirrel" out of 3/4" square stock fir, I've made my share of slightly offset holes! >There are three other Piets under construction within 40 miles of me I must have missed it in your post.

    Subject: Re: Ben Charvet's Piet/Douglas fir
    --> Pietenpol-List message posted by: "Ben Charvet" <bcharvet@bellsouth.net> Well, the mock-up looks real good in person too....and you're not the first person to ask why the wood wasn't good enough. The grain run-out problems were within a foot of the end of the longerons on 2 or 3 of them. If it had been in the middle I might have been willing to take the chance. I figured I had a chance of breaking off the tail in a hard landing, or losing the engine and having a severe out of balance problem :). It probably would have been fine, but at that stage of the project I wasn't sure if it was wise to make such a compromise. Also, I hadn't made many connections at EAA 866 yet. Probably should have had one of the local builders look at it. Anyway, after I figured it was just a mockup, I used cheap plywood, and carpenter's glue to put the thing together, so it really is just a mockup now. I live in Mims, Fl, which is just north of Titusville (next to Kennedy Space Center) I need to update the website. I made rib# 12 tonight and bought a corvair motor for $100 today. My progress has been slowed by the illness and death of my father Good Friday. He's the guy standing in my shop in one of the last pictures on the website. That was the last time he was in my shop and he will be sorely missed.

    Subject: Splicing fuselage longerons?
    --> Pietenpol-List message posted by: "Ben Charvet" <bcharvet@bellsouth.net> Hi all, Gordon has some sitka spruce available pretty near to me. Anyone out there have any opinions or experience/advice about splicing fuselage longerons? I read in the EAA wood book that some designs call for laminating up the longerons, and It looks like a 16:1 scarf might work. What do you think?

    Subject: Re: Splicing fuselage longerons?
    --> Pietenpol-List message posted by: <gcardinal@mn.rr.com> Ben, The longerons on NX18235 are spliced. Uppers are spliced in the cockpit area and the lowers are spliced aft. Splices were located where the longerons curve the least. The splices have a slope of 12:1.

    --> Pietenpol-List message posted by: Galen Hutcheson <wacopitts@yahoo.com> Ben, Greg is right. 12:1 is good enough. You can laminate the longerones and they would be stronger, however, the 1" X 1" spruce is plenty strong enough.
