Hi guys I was just getting ready to fire up my table saw tonight to cut out the trailing edge piece for the center section when I thought about making the rear semicircle cutout from the center section. Would you greatly recommend this and is it hard to do? Does it greatly help getting in and out of the cockpit? Thanks in advance....CB________________________________________________________________________________Date: Fri, 31 May 2013 16:07:18 -0700 (PDT)
Pietenpol-List: Center section rear cutout.

Charles,When I started my project 10 years ago I did not plan on putting in a cut out or a flop. Seven years ago I was far enough along that I was able to put the center section above the fuselage with mocked up cardboard wing bottoms. I tried getting in and out of the fuselage with the fuselage in the proper on the ground stance. Fast forward to last summer and the wings are on, the center section is on and the fuselage is on its gear. My cabanes are extended 2 inches and I slanted the wing back 4 inches for testing. I could get in but it was more difficult. My AP/IA kept trying to tell me to put in a flop or a cutout but I resisted. Finally, I sat in the cockpit for one hour then tried to get out. I did it, but it was a struggle. I decided then to take the center section home and install a flop. What a difference! It was only a half days work, but well worth it. It would have been a whole lot easier if I did it during the original center section construction. If you go to Chris Tracy's West Coast Piet site and look under my photos, you can see a photo of my set up.Rick SchreiberSent from my iPadOn May 31, 2013, at 5:49 PM, "Charles Burkholder" wrote:> Hi guys I was just getting ready to fire up my table saw tonight to cut out the trailing edge piece for the center section when I thought about making the rear semicircle cutout from the center section.

FWIW, I did my 613.5 the way it sounds like Paul did. Spars are perpendicular inreference to the lower cap strip. Also, I built the ribs anticipating a 1 inchspar. I then used the same measurements as the Pietenpol airfoil ( 6 and 3/4"from nose to front face of the front spar, 28 and 3/4" front face of frontspar to face of rear spar, etc).I hope that helps.--------Semper Fi,Terry HandAthens, GARead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Fri, 31 May 2013 21:16:13 -0500
