Hello to other Piet fans. I am new to the chat group and I am ready tobegin my Piet project. I got my plans from Don P. and I am going to buildthe wood version. This brings me to the question of the day.I would like some different feed back on wood used in the piet. I haveheard builders use everything from top quality aircraft spruce to douglasfir out of the local lumber yard. Obviously nothing is to good when itcomes to your life.

Hello good Piet-ple...Thought Id post an update on my projectI was able to spend 8 of the 9 days off during the holiday break in my workshopmostly fabricating small pieces and parts. There are lots more to go and yetIm fine with that as I am enjoying the adventure/experience/journey.Part of the challenge with the Pietenpol design, especially with the steel-tubefuselage version, is that so much of it is not defined on the plans. I thereforespend a great deal more time designing certain elements than I actually dofabricating the parts. An example of this is where the shoulder harness and seatbelts attach to the frame. The photos show that my solution in this area has been to form a 4130 steel tubebow behind the pilot and passenger seats. The nylon shoulder harness strapswill wrap around these tubes and should not interfere with the other things thatshare that same volume such as the back of the instruments, the cross bracing,aileron control cables, and instrument wires & pitot tubing. Mocking the areaup with string and cardboard parts has really helped to visualize this volume.The pilots shoulder harness may still route back to fittings under the turtledeck aft of the seat, but the bow will share the load and provide supportunder the turtledeck structure in case someone sits on it while climbing intothe pilots seat.I have been asked how much of the design I changed from the original plans. Mybest answer may be to say that from the side view, it is dimensionally EXACTLYthe short fuselage steel-tube Pietenpol dimensions taken directly from an originalcopy of the 1932 Flying and Glider Manual. The fuselage was made two incheswider than plans and I increased the diameter and number of tubing segmentsto carry structural loads around the area of my left side door cutout. Ive included a screen shot of the fuselage truss I created in CAD which shows theexact lengths of the cross members (centerline-to-centerline dimensions) becausewhen you make the fuselage two inches wider than plans, all the dimensionsin the tapered (aft fuselage) section are different than the plans.In addition, I have installed more structure than that image shows to attach thingslike rudder pedals, seats, and control bar fittings. Everywhere a criticalpart mounts to the airplane, there will be a tab welded to the frame so allcritical parts are attached to the structure itself, not secondary structure suchas the plywood floor.All this redesign adds some weight but the tubing itself is surprisingly light(overall lighter than the wood fuselage by about 30 pounds if my numbers are correct)and the few times I may add a bit of weight to my airplane I want it tobe for a conscious purpose.Note: As a caveat, I have not yet completed this plane, so all things at thispoint (January 2012) are just my current solutions/thinking and are subject tochange(!)--------Jake Schultz - curator,Newport Way Air Museum (OK, it's just my home)Read this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/5_is ... ___Subject: Pietenpol-List: Re: Update on my steel-tube Pietenpol project...

Thanks Jake. The pictures and work are great, and I can see the amount of designingyou have incorporated so far, such as the brakes, rudder pedals and seats.I came home today, and my plans were in the mail box. I have lurked about thesite for many years, and met several piet folks over the last year. I have beeninterested in building a steel tube piet with possibly an 0-200 for power.I was thinking of using a form of the long fuselage by stretching the steel tubeplanand possibly increseing the tube size.. Keep up the great work!Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Update on my steel-tube Pietenpol project...
