Mike,I think I see where you're getting confused. The plan set issued by the Pietenpolfamily has one sheet that is actually two separate drawings, combined on onesheet. Actually it's one drawing, plus some weight and balance data. The bottomof the drawing sheet is the steel tube fuselage drawing, which is just a duplicationof the same drawing that was included in the 1932 Flying and GliderManual. The top part of the sheet is weight and balance data provided as an example- with the data obtained from one of BHP's actual planes in 1966 - in thiscase, Corvair powered. The data doesn't necessarily have anything to do withthe steel tube fuselage. The top half of the drawing sheet has no connectionto the bottom half.The only advantage of the long fuselage has to do with the height of the pilotand/or passenger. There is more leg room with the long fuselage, but, as Ryansaid, it does nothing to address W&B issues. Whatever you build, keep the taillight.Bill C.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Contintental Motor Mount question

I was going over the plans last night, thinking about the tubing I need to orderfor some of the metal work that I have ahead of me, and I noticed a detail inthe plans for the Continental Motor Mount that isn't quite clear to me.The part in question is the "spool" for attachment of the engine to the mount.The drawing calls for 0.625 O.D. x .049 tube, to be reamed for a 7/16" bolt. Well,0.625 x .049 tube has an inner diameter of 0.527", and 7/16" is .438", sothat tube can't be reamed that size, since it's already bigger than that.Looking a little more closely at the drawing, it's actually drawn with a smallertube inside the .625" tube. What's the deelio? Is the inner tube supposed tobe loose, or is it welded to the outer tube? If it's welded, why not just useda thicker wall tube (.625" x .095")? If it is not welded, why not?

I installed Foxit and I also have a program called php tablet. Internet Explorer still kicks it off and wants me to send an error report. I'll wait until later -- maybe explorer is just goofed up right now. ----- Original Message -----

That is exactly what I did Bill, ordered a 12" piece of the .625 x .095 4130 tubingreamed to fit 7/16 bolt. Might even have some extra lazer cut washers kickin" around if you want them.--------Adrian MWinnipeg, MBCanadaRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Bill, I actually just bought some 4130 stock and had a machinist at workturn down the spools for me, then welded them to the mount.Jack PhillipsNX899JP "Icarus Plummet"Raleigh, NC-----Original Message-----

Okay, gents, thanks for confirming that I wasn't just imagining things. So whydo you suppose the part was drawn that way (tube inside a tube)?Ben, the plans don't show a washer welded on the back side. Did you use the samesize washer in the back? Seems like there might not be enough space there, withthe tubes converging from behind.Bill C.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Tue, 8 Feb 2011 18:53:36 -0600Subject: Re: Pietenpol-List: Re: need help with wiring
