    Subject: bungee chafing etc
    Hi all, Instead of leather, I cut up some really thick rubber inner tube protectors I had laying around. Leather is probably more "period" though. Likely heavier, but I know that the Germans in WW1 sprung some of their axles using long springs wrapped around the axle just like bungees. I think it was they had more steel than rubber. They looked like screen door springs stretched and wrapped. Looked bulkier than bungee, and is heavier (I weighed a foot of each back when I was considering it) BUT. it wouldn't chafe. Douwe

    Subject: bungee chafing etc
    Greg and Dale used the leather wrap method "I purchased the leather from a local saddle shop. It was referred to as "sole leather" because it is relatively thick, about 1/8". It was very stiff but leather can be formed easily by soaking it in water for a few minutes. It is attached to the bottom of the ash block with a couple of small screws but the bungees keep it held in place. Round headed rivets per the original plans instead of threaded fasteners in this location would most likely eliminate the need for the leather cuff. Greg Cardinal" Link to a drawing of their setup http://westcoastpiet.com/images/Greg%20and%20Dale/images/Anti%20Chafe%20Cuff .pdf Another idea I have seen is to place a wide board on the bottom of the ash block so the bungees are not al likely to touch the bolt heads. You can see it in this picture. http://westcoastpiet.com/images/Larry%20Williams/images/Air_Venture_2003_tri p_104.jpg Chris Sacramento, Ca Westcoastpiet.com _____ From: owner-pietenpol-list-server@matronics.com [mailto:owner-pietenpol-list-server@matronics.com] On Behalf Of Douwe Blumberg Sent: Friday, June 07, 2013 4:41 AM Subject: Pietenpol-List: bungee chafing etc Hi all, Instead of leather, I cut up some really thick rubber inner tube protectors I had laying around.

    I am sitting in the Cleveland airport waiting for a flight to Edinburgh Scotland. I'll be touring with a group, but I'm wondering if there are any Scots or Brits between Edinburgh and York that I might be able to catch up with sometime in the next week? Thanks! Kip Gardner

    Ok one more question about this. How far does the axle go up off the ash blocks when going over bumps, landings etc... I may toy around with a spring suspension for the straight axle. Ill have to decide if im willing to increase weight a bit to avoid the frequent bungee changes. -------- Paul Donahue Started 8-3-12 do not archive Read this topic online here: http://forums.matronics.com/viewtopic.php?p=402246#402246

    From: Michael Groah <dskogrover@yahoo.com>
    Ok Gary. My straight axle gear has a width (center to center of tire) of 62.75 inches. With the upper longeron level the distance from the ground to the top of the upper longeron is 54.75 inches. I have 90 landings on it so far and I think the handling is far better and easier to land than the Champ I did my tail wheel endorsement in.

    Paul it is not that bad. You just need some help holding the stretch in it while you get another hold on it. This time it was really easy. My son and our friend Kevin(47 & 29 respectively) came over and I sat on my behind and watched and they did it in about 20 minutes. -------- Jerry Dotson First flight June 16,2012 Flying in phase 2 Lycoming O-235 C2C Jay Anderson CloudCars prop 76 X 44 do not archive Read this topic online here: http://forums.matronics.com/viewtopic.php?p=402258#402258

    Gary, I just measured mine. It's 59" between centers. I would not consider my air plane squirrely at all FYI. Dan Helsper Poplar Grove, IL, on my way back to TN via Grinnell IA. -----Original Message----- From: Gary Boothe <gboothe5@comcast.net> Sent: Tue, Jun 4, 2013 8:55 pm Subject: RE: Pietenpol-List: Re: West Coast Pietenpol Gathering (aka: "Brod head West") Paul, As Kevin pointed out to me, the correct aircraft terminology is not 'squirrelly', but 'tippy'. Tippy in the sense that it tips over (;-))... an d scrapes wing tips! Not only did I have this issue, but also my 15,000 hr flight instructor/test pilot who had a minor scrape a few weeks ago. I thin k I may have posted two wheel dimensions of 52 and 57", but the correct numbe r is 52" from center to center of the tires. I have 21" Harley Sportster wheels (which have done quite well with my side-load testing program, I might say), but I do not know the height at this moment. Rebuild, which is really minor, will also consist of remaking the gear to a wider, lower stance....do NOT want to be tippy...

Glad your ok, an d atleast you didn't have a prop strike. could have been a much more expensiv e rebuild if thinks went slightly worse. Sounds like the taller gear are a little more squirrely. If you don't mind, (and if you do mind, i understand), could you share in what way your aircraft is a little tricky to land? did you run out of rudder, slow roll rate, is it squirrely just on the tailwheel or while just on the mains......... this info would help some of us in the build stage to make some gear config decisions. maybe we should start a new thread having piet owners state the particulars of their gear setup. (height, width, size tires, and type of tailwheel, swiveling, castoring, fixed). how they feel they handle and what they would do differently to make the plane more docile if needed. -------- Paul Donahue Started 8-3-12 do not archive Read this topic online here: http://forums.matronics.com/viewtopic.php?p=401988#401988
