Pietenpol-List: Stringers on Pietenpol Turtledeck

Post by matronics »

Subject: Pietenpol-List: Stringers on Pietenpol TurtledeckHelp Somebody,I am trying to figure out how to know where the stringers will go from one bulkhead to another. They would all be the same numbers of degrees radially if the bulkheads were all the same distance apart, but they're not. Close, but not the same. Are they close enough? I hate to cut notches in the bulkheads and then find the stringers have waves in them.I can always just run one from one bulkhead to another and mark all those in between, but there must be another way, any ideas? I am beginning to think this is the fastest way.Second question, since the plans are so detailed, is everyone using 1 inch by 1/4 inch stringers? Third question does anyone make the landing gear fitting for the cub type gear? Thanks, Jim Boyer, Santa Rosa, CA.PS. I have the wing ribs, tail surfaces, and fuselage almost all framed up. I think I am at that point where you say you're 80% done with 90% left to go.________________________________________________________________________________

Jim,What you're describing is basically the way I ended up doing my stringers - I took a chalk line and snapped on the bulkhead and notched it there. I didn't get it perfect, but it is pretty decent. Some folks are like me and take days and days, but I hear some folks had no trouble at all, and knocked out these stringers in a couple hours! A lot of folks support these stringer with individual pieces of stringer material glued to the bulkhead. That looks like a good way too. You can get a lot of ideas from the ever Aicamper website - by the way - well worth a $5.00 Paypal donation! I ripped-out some 1/4" x 1" Doug fir strips from Home Depot for the stringers - worked fine. I think Replicraft sells ready made landing gear mounts for the split axle steel gear. I think they may be at www.replicraftaviation.com?Someone will know. Good luck on the stringers, the plans ARE very sketchy back there!Gary MeadowsSpring, TX________________________________________________________________________________

I Hi Gary,Thanks for the reply. I was wondering if I was overlooking something. Using a chalk line sure does seem like the faster way to do it. I have the backup stringer support for the bulkhead right behind the cockpit made, just wanted to be sure I didn't screw up doing the stringers. I have going to Mead Clark lumber yard on my list for today to get some Doug Fir to make stringers.I'll check with Replicraft about the landing gear fittings. I wasn't looking forward to making them.Thanks again for the reply, Jim________________________________________________________________________________Date: Fri, 30 Mar 2001 14:30:31 -0800 (PST)

Doug BryantHi Doug,I am building the cub type gear (bungee cords around 'x' telescoping section). I'm not looking forward to drilling that round stock off center and welding the whole mess. Number one, I can't weld, and number 2 drilling that rod off center sounds like a good way to waste time and material!Thanks, Jim________________________________________________________________________________

Subject: Re: Pietenpol-List: Stringers on Pietenpol TurtledeckHi Del,Thats what I ended up doing; using a chalk line and snapping a line on all the bulkheads and then cuttine the notches where the line left chalk. It took me most of the afternoon though to cut the notches what with my procrastination and all. The of course tonight had to watch the San Francisco Giants play Seattle (Giants won 2 to 0). Tomorrow am cutting up some western cedar to use for the stringers 1"x1.4".Cheers and thanks, Jim________________________________________________________________________________

Do you mean the gear for the improved aircamper (1933 version) or do you mean a copy of an actual Cub gear? Are you building A Grega or a Pietenpol? I have built plenty of Steel gears and suspension struts for the Improved aircamper and could probably help. Give me some more detail. If you are building to the improved aircamper plans go to the page and area on the page. Doug Bryant ________________________________________________________________________________

Subject: Re: Pietenpol-List: gear bungeesDon,On the bungee wrapping for the improved aircamper gear , I went out today and took some closeup pictures. If you would like, I could send them in the mail. Here is the rough process all done with wooden plugs installed. I use 3 1/2 feet of bungee per wrap and of course there are four wraps. Wrap the ends with medical cloth tape, wrap around lower lug and clamp, make three wraps around as tight as possible, make an extra loop and connect it to a motorcycle tie down strap passing thru the spoke wheel to the axle. Then I hide behind the wheel and pull pretty tight, then go back under the plane and clamp. When the clamping is complete, I unclamp the extra loop and stow this extra length. The picture will make this very clear because the process is really easy and I can complete the job by myself. I am going to develop some special tools and try another way, but for now, this is the method I use. I change the bungee every other year.

Do you mean the gear for the improved aircamper (1933 version)Hi Doug, Yes I mean the 1933 Improved Aircamper. I am building a Piet. The plan sheet that looks intimadating to me is Drawing #3 landing gear fittings where you have to drill a 1/4" hole 1/8" off center and file a flat on it to line up the gear 'V' where they join the fuselage. I am procrastinating working on these fittings. I can find all sorts of things yet undone on the fuselage before I need to commit to these fittings.By the way I have all the formers/bulkheads notched and the stringers fitted now, will glue them tomorrow after church. Thanks for you chalk line suggestion, it worked great.Cheers, Jim________________________________________________________________________________

Jim, Making the gear I thought was one of the toughest parts of thisproject. One of the tricks I used was after making the plates and mountingthem on the fuse, I cut and ground the round stock close to what the plansshow. Then I put the hinge pieces on the plates with thin strips of tape.Using a long rod, I held it along the axis of the hinges to find the holepositions. I also marked the postion of the hinges on the plates. Then Idrilled the holes, removed the plates and tack welded the hinges. Then I putthe plates back on the fuse, put the rod thru the hinges ( the small tackwill let you adjust for alignment) transferred the whole thing to a jig andwelded. I basically did the same thing with the rod when I welded the hingesto the V legs. Making the jigs was a job in itself but was well worth it. Ihope this helps. Good luck,CarlPlease visit my website atwww.megsinet.net/skycarl-----Original Message-----

I (and a host of others) can can help you with this gear and have a great set of jigs to build the entire gear. I use four jigs, one for the V, one to set the lugs, one to set the axle, and one to set the bungee lugs on the suspesion struts. If you need of set of drilled lugs, I'll make you some. I think I still have enough material.________________________________________________________________________________

I do not have any experience or tools for working on steel, so it slows me down.Thanks Doug, Jim________________________________________________________________________________Date: Sun, 1 Apr 2001 18:11:07 -0400

I would would think that somehow you're going to have to get some help on the some of these steel parts perhaps from another builder in your area.
