Pietenpol-List: Strut tubing sizes

Post by matronics »

Original Posted By: "David Paule"
Still working on the particulars of my struts. Tying to determine thecorrect size and thickness of the tubing to order. Of the 3 diagrams I'velooked at, the sizes differ. For the inside tube to slide freely within theoutside tube how much clearance (difference) should I have? The HV Designhas .06 clearance. Bingelis clearance is .009. The Debolt drawing is also.009 which seems tight. Wish I hade the tubing on-hand so I could try.Then I just need to figure the springs!Thanks!JackDSM ________________________________________________________________________________

Hey Jack,I guess I'm not familiar with the "HV Design" and the "Debolt Drawing", and I don'tremember what the plans call for. I can check my plans and see what it callsfor and translate to decimal wall thickness. Off the top of my head though,.060" would be a huge amount of clearance fit. The .009" dimension soundsmuch better.Don EmchNX899DERead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Never even thought about paint.Steven do you remember the tubing sizes and thickness for your gear?JackDSMHey Jack,I guess I'm not familiar with the "HV Design" and the "Debolt Drawing", andI don't remember what the plans call for.

Jack,I like the Debolt drawing. I actually recognize that from a past Frank PavligaSr. newsletter. If I was doing springs that is how I would do it. .009" clearancefit is plenty, even with paint. That will soon wear off though. I'd justkeep it greased up in there. Every now and then I think of making a springgear for mine. Those bungees can be a real pain to wrap. I just like the "Pietenpol-ish"look to them though.Good luck!Don EmchNX899DERead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Sun, 1 Nov 2009 16:37:00 -0600Subject: Re: Pietenpol-List: Re: Strut tubing sizes

Flew Ed deLancy's Piet N6926J today. Ed bought the plane, a one piece wingA65 Piet from northern MN. He brought it back to WV on a trailer just afterBrodhead this past summer. The plane was reported to have one hour. Heworked on the thing several hours a day from then till now to get ittrimmed and in good flying shape. Ed is an A&P, IA, CFII and airline pilotbut not much taildragger time so I did the honers. Did some tail up fasttaxi work 2 days ago and told Ed it was ready to fly. We put the cowl onand waited for the wind to calm down, it never did. Today was clear as abell and at about 4:30 PM about 50 degrees and winds almost nill. It was myplan to get the tail up and do a few more fast taxi's. The tail came up,pulled the throttle back a little to keep it on the runway and next thing Iknew it was flying. I moved the stick very gently one side of center to theother to varify ailerons worked, they did so added back in some throttle.The plane flys great! The only problem was the little flapper thing on thepitot did not move so no airspeed. The Piet flys so much like my GN-1 thatwasn't a problem. We will get that fixed and put some more time on ittomorrow. Hales Landing now has 2 flying Piets!Skipskipgadd(at)earthlink.net________________________________________________________________________________Date: Sun, 1 Nov 2009 21:49:02 -0500Subject: Re: Pietenpol-List: She flys!

Jack,Just use .058 tube for the outside tube and the next smaller size for the insideand it will work. I used .058 for both, but have not flown my Piet yet.Skip----- Original Message -----
