Cub style gear?? Those must be GN-1's not Pietenpol. The GN-1 is a modified Pietenpol with enough changes to no longer be called a Pietenpol. I believe the cub gear mounting changes the location of the axle compared the Piet. Also the GN-1 has a modified airfoil with a different leading edge. That said, are you building from authentic Pietrenpol plans or the GN-1 plans?About the fuselage, the only challenge I faced was devising a sanding drum set-up to scarf the edges of the mating joint of the two pieces of plywood doublers on the sides of the fuse.I did not have to steam the longerons to pull the tail together.I use the West Epoxy system for all my construction.I used an office stapler to staple the gussets to the ribs and the fuselage rather than the tiny brads. Much quicker and easier.The only other challenge so far was to find an economical metal cutting bandsaw.I finally converted my wood cutting bandsaw to a multispeed using a DC motor with speed control.Roman BukoltBuilding a Corvair powered Pietenpol NX88XN----- Original Message -----

Hane you installed your battery yet? That can add 25 lb to the firewall. You can also move the wing back 1 more inch, that will also help. Mine is back 4 1/2". I built a short fuse, not knowing at the start what engine to use. After deciding on an A-65 I also added a 4 gal reserve nose tank, a battery to the FW to get CG.Dick N. ----- Original Message -----

FW: Pietenpol-List: Fuse constructionI don't think anyone actually builds the exact plane that Pietenpol designed, too many modern materials available and necessary. Afterall who'd want to use a tractor mag when there are better options, or grade 3 bolts. Same goes for the original Rutan designs for the Varieze and Longeze, every builder adds or subtracts their own mods. That's why it's called experimental. But we still have the purist out there that insist it ain't a Piete unless it is build just like Bernard did, fer git abouut it dreamers. N-1003B's 4130 fuselage, 0-235Lycosauros engine and Aeronca wings, flies just fine thanks. Got $5 bucks that says my "Piete" can beat anyone out there's Piete in time to climb to 3000' agl, even the purist, how about Lakeland in Apr07. Better materials make better planes, just like the Papa John's Pizza commercial. Think Bernard would appreciate the improvements and still be proud to stick his name on the design.Gordon Bowen ----- Original Message -----

Hello Dan,In thinking back, I believe the fuselage was fairly straight forward. There maybe some searching for measurements in other places on the plans. Once you buildup the sides it would probably be a good idea to build a jig to bring thesides together, upside down since the top longeron is flat. I would start fromthe front and work back to the tail in installing the cross-braces. Squarenessis obviously important. I wouldn't make any metal fittings until the woodworkis finished. Seem to get a better fit if you build them to your specificfuselage. I'd leave the firewall off until all the fittings and controls werebuilt, gets a little tight in there. I made the front seat framework permanentbut made the plywood seat removeable to service the rudder bar. I routedthe elevator cables through pulleys where they go under the seat. Helps for alittle smoother movement. It's a good idea to beef up the instrument panelswith laminated wood bows glued to the plywood. Adds a lot of strength for a verysmall weight penalty. Really, really resist the urge to add much of anything.The fuselage is quite strong if built with quality wood and good tight joints.I've found that out with some not so great landings! Try not to add muchto the panel, you won't use it anyway. The view outside is much better thanlooking at the panel. If you build it like the plans and expect a 1930's airplaneyou won't regret it.Don EmchNX899DERead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Dan:Two of THE most talked about bugaboos with the fuselage that have not been mentioned yet are:(1) decide on your gear type and location BEFORE building. Retrofitting the Jenny style gear to the '32 fuselage or later is a bear;(2) make SURE you understand the construction of the tailpost. Read it, draw it, read it again. Too many people have glued in two 1/2 inch pieces and tried to pull them together. It does not work like that. Even after several readings, it is more difficult in practice than it looks.As for the discussion that has made it into this thread regarding the steel strap across the belly, I maintain that it is not SUPPOSED to take any compression loads and does not need to be square stock or anything else. There is nothing wrong with a wooden fuselage or any other component flexing on landing. The strap was added as an afterthought, and only as an optional suggestion per the plans, as a safety device to tie the struts together in case the bolts pulled out of the fuselage. at the gear/strut fitting. The wood, metal, workmanship, and maintenance and upkeep of amateur builders in the 1930's was such that a rotten longeron or two was not out of the question. The quality materials and workmanship we have on this list, I believe, negates any need for that strap. I am not going to install it, just something else to bow, corrode, hold moisture against the wood, and look bad.Just my two cents worth.Gene ----- Original Message -----

Dick:I agree that the Jenny gear loads the fuselage differently and may not make the fuselage bow the same, but I think the original purpose of the strap would still be there, as a safety device in the last resort to hold the wings on if the fitting should pull out, or actually to prevent the fitting from pulling out. I think that this is an extremely unlikely concern.Just to give another example of this type of concern, the seat belts in the Travel Air originally attached around two oak seat rails. Because there was an instance where the oak rails became so rotten that they broke off and the pilot, seat, belts and all fell out of the airplane, the belts were moved to attach to the longeron. I do not anticipate that solid oak rails in my airplane (or any other part) will rot inside the hangar (they were probably kept outside then) I have mine attached to the oak like they originally were. Poor conditions, poor maintenance, poor inspections created the problem. How a solid piece of oak could rot that much without being noticed is beyond me.Gene ----- Original Message -----

Subject: Re: Pietenpol-List: Fuse constructionSlightly off topic, when building the fuselage, do you have to steam the lower longeron to get the bend in it? The top one looks straight, the bottom definitely looks to have a bend. Curious mind wants to know, now I go back tolurking!Boyce________________________________________________________________________________

Hi Boyce,No, you do not have to steam the lower longeron to bend it. I think theonly piece I had to steam was the top piece of spruce on the wing ribs.That is a pretty good bend! Cheers, Dave-----Original Message-----
