Mike,=0A=0APlease see the attached. As you might see, I have elongated the "sheath" tube on my "axle locator" tube system into an oval shape. This is to allow a "rocking" motion on the gear, without putting an undo strain on the tube that is welded onto the axle. Please note I have not flown with this set-up. I unashamedly copied it from Simon McCormack from "down under" www.westcoastpiet.com. They look at things from a "different" perspective there, and many times have some superb ideas. Also, have you looked at Chris Tracey's straight axle gear fabrication instructions on the westcoastpiet site?=0A=0ADan Helsper=0APoplar Grove, IL=0A=0A=0A-----Original Message-----

Thank you for the help, both Jack and Dan.- Yes Dan I've read the gear construction write up that Chris did on westcoastpiet.com.- I chose to do mine differently (right side up), but still got the job done.- Thanks for the tips.- I'll get to work on the axle part soon.- Hopefully you can see the attached pic of what I have done thus far.- Mike GroahTulare CA--- On Mon, 6/15/09, helspersew(at)aol.com wrote:

MarkI don't weight in very often, but I wanted to give my thoughts on this subject.I have a rare condition which my wife coined chronic tightassitis, with complications of overthinkitis. what this means is that I have looked over Doug fir in detail.I even laid out the numbers in a spreadsheet, and modeled the parts in Pro Engineer to check size reductions.what I discovered is that you can reduce the longerons by about a 16th of an inch if memory serves me and still be above the Stats and strengths of spruce while at the same time reducing the weight and offsetting some of the weight penalty. with that said the only number of Douglas fir that is less than Spruce is the Modulus of Elasticity (again if memory serves) and unless you plan on fatigue testing your piet, with aerobatics that number should never come into play, if you have a tendency to smack into hard things remember that Doug fir won't bend as far as spruce before it cracks. My ribs are all out of Doug Fir that is 12-14 growth rings per inch with a runout of less than 1 inch in 60, cut from a 12 foot 4x4 purchased at Menards for 12.95 I believe.Just my thoughts,JakeMark Roberts Sent by: owner-pietenpol-list-server(at)matronics.com06/16/2009 12:13 PMPlease respond topietenpol-list(at)matronics.comTopietenpol-list(at)matronics.comccSubjectPietenpol-List: Doug Fir as a substituteFirst, I would like to thank everyone for the patience you've shownwith my deliberations over the choice of wood or steel for the fuse. Irealize after looking at my posts that some of it might have been overthinking the issue, but if I am spending 4 years (I hope less) onbuilding something, I want to make sure I am happy with the results.Light = better for me

)However, looking at Doug Fir as an alternative to spruce... I amre-reading the EAA book on wood, and it struck me as funny that thesecond article in the book was about using Fir as a substitute forspruce. One of the next articles in the book was NOT to use anythingbut spruce for critical members such as Fuse longerons.Now, some reason need to be applied here, as everyone has a few basicthings in common: Body orifices and opinions (phrase cleaned up herefor general consumption...). I get that one guy says never use fir andanother says it's OK. The funny thing is, is both seemed to haveimpressive credentials. The one praising fir was a Dr. of aeronauticsand involved in sailplanes and the other was Mr. Evans of Volksplanefame. He said after reading about compression fractures in wood, thathe went back to recommending only spruce for structural members of theplane. Well (sigh).So, I am thinking, weight not withstanding (remember all of my otherposts wringing my hands about steel over wood??), what would be theequivalent size in fir to equal the same strength in spruce? Is therea rule of thumb? For instance, if I were to order from ACS or Wicks 1"x 1" capstrip spruce for the fuse construction, would the equivalentstrength size be say, 3/4" square? What could the fir be pared down toto equal the strength component of the spruce.Has anyone ever seen a comparison such as this?The first mentioned author said 'nuts' to the changing of sizes forthis type of substitution, and said just use the regular size calledfor and get over the weight difference. I am re-drawing / modeling theplane in stages in Sketch up 7 to determine all of the little thingsI'll encounter in the real build (a way of scratching the itch tillall the money is there...) and I could work out the inconsistencieswith the plans size changes then. I'm going to have to do this anywayas my height will warrant the deepening of the fuse a couple of inchesfor my long frame.Thanks for the feedback. I hope the posts don't seem like idle'excitement' chatter, as I am trying to wrap my head around thedetails before the build.(As an aside, the more I am reading, the more I am understanding thisis a normal phenomenon amongst homebuilders of the first go 'round. Ijust feel excessive in the ponderings. Job? What job.... I'm at 5000on a nice summer evening looking down on wafts of smoke billowing offof an agriculture burn, and seeing the lights pop on in little housesas I set up for final...

The insides of all the cowlings on 41CC were left in naturalaluminum. I sort of wish that the cockpit cowlings were atleast primed inside because they are visible. However, Corkyhad the wonderful presence of mind to have everyone who helpedhim on the airplane sign their names inside the engine top cowlingusing a black marker. Since I've owned the airplane, I've hadseveral others add their names inside the cowling... like SalHernandez, welder extraordinaire who did all of the landing gearand cabane strut repairs. I need to have engine guru Jeff Scottsign it, and tech counselor Norris Warner, and sheet metalmaestro Ed Talamantez, and Charlie, and... and... so many more!The inside of that cowling will carry a story with it for along time.Oscar ZunigaAir Camper NX41CCSan Antonio, TXmailto: taildrags(at)hotmail.comwebsite at http://www.flysquirrel.net________________________________________________________________________________Subject: RE: Pietenpol-List: Doug Fir as a substituteDate: Wed, 17 Jun 2009 08:15:28 -0400

My public apologies to Owen for doubting him. I did some searching on the ETLB forums where the Mini-Max guys hang out, and it turns out that those kits have been using some mix of spruce, douglas fir, and "northern" white pine for a number of years. I couldn't find difinitive answers on what was pine, and what was spruce, though.I guess I'll have to dig my fin kit out and have a closer look!I need to check the wood guides to compare the specs on the white pine.Sorry to stray off topic.Wayne Bressler Jr.Taildraggers, Inc.taildraggersinc.com>>>>________________________________________________________________________________

Flying weight is 626 pounds (short fuselage, A-65). Total cost for the fir was less than$600. Spars, longerons, the whole works. 108 brd feet at about $5.75 perboard ft.
