Bob I don't remeber if I read this in the BPA newsletter or earlier on thissite but it seems to me that one of us had tried using motorcycle chainmaster links as shackles. The test if I remeber right was a length ofaircraft cable shackled to a tree and a Ford Bronco. The cable and shackleswon. It would probably work although I would suggest that industrial masterlinks with drilled pins for cotter keys would allow for safety wiring thelink.Test it! if you trust it, use it!John Mc----- Original Message -----

Don't know what process you're using but Polyfiber has a really good manual.It shows their whole process including covering, stitching, taping etc.(and what order to perform in) Also a VHS tape is available. Helped me aLOT.Best, Bert----- Original Message -----

A quick hint on fittings, maybe I even read it here on the piet list.Get a saber saw, and a fine tooth hacksaw blade. shorten the blade, and Grind away the back until it fits the saber saw.Use this to cut your sheet steel, and plate. Sure works better than a hacksaw.Bob>From: "Bob Seibert" >Reply-To: pietenpol-list(at)matronics.com>To: List Pietenpol >Subject: Pietenpol-List: Source of shackles>Date: Tue, 05 Dec 2000 16:46:22 -0600>>>>Can anyone out there advise on a good source of cable shackles?>Looks like I need about 12 of them for my project and I hate to pay $5>apiece for them!

I am looking for information on rib stitching. Some time back (severalyears) I was shown rib stitching that as I recall, pulled the knots underthe fabric as you progressed to the next stitch. I can't find anyinformation on it now that I need it. Can some one help me out on this? Ialso saw an illustrated article a few months ago ( I think) that showed amock set up to practice rib stitching. I only subscribe to the Pietenpolnews letter and EAA Sport Pilot but seem unable to find the article. Doesanyone recall seeing such an article.Thanks for any helpCarol and RalphRaymond________________________________________________________________________________

I've got my rib stiching technique down, having just finished the tail feathers.Now I'm ready to start the wings and would appreciate any helpful suggestions.My basic plan is to prop one up on edge and with a helper on each side, passthe needles through back and forth. This sounds good, but I'm not sure howthe person can find the hole on the other side as they pass the needle through.I've been advised to do three needles/ribs at the same time, which makesa lot of sense.I know once we start, we'll figure these things out, but I like to stand on anyone'sshoulders whenver possible.Thanks, hope you're all well!!Douwe________________________________________________________________________________Subject: RE: Pietenpol-List: rib stitchingDate: Thu, 22 Sep 2005 08:52:00 -0400

Well, having just learned how to rib stitch myself, I will say that I did it the way Corky had originally done it on the vertical stab... marked the stitch locations and then fired up my pointy little soldering iron to melt little holes in the fabric at each stitch location. Made it real easy to see through and pass the needle through, and super easy to pull in the knots to hide them. I didn't even try NOT pre-punching the holes and it would seem to me to be a lot harder to pull the knots inside to hide them if you don't pre-punch.Did the same thing with the bolt holes... melted them through the fabric with my soldering iron prior to Poly-Spray and Poly-Tone. Turned out swell.Oscar ZunigaSan Antonio, TXmailto: taildrags(at)hotmail.comwebsite at http://www.flysquirrel.net________________________________________________________________________________Date: Fri, 23 Sep 2005 12:19:25 -0700

Just taper a long sharp point on oneend, and flatten the other end with the hammer and anvil, then drill a hole inthe flattened end to pass the thread through.Chuck G.________________________________________________________________________________

Hi guys,I want to thank you all for the excellent ideas. It's time like this that thegroup really shines, real "hands on" ideas!! I'm getting the hang of it, I havn'ttried the soldering gun thing, but think I will, plus that would really letme see through the hole easily.And Mike, yes I am hiding the knots!Douwe________________________________________________________________________________Date: Sun, 25 Sep 2005 13:15:22 -0400

I'm not really worried, or even thinking about moving the wing. All airplanes move the wing to correct for CG (biplanes or parasols anyway). If I move the wing, the geometry is what it is.What I am TRYING to get to is that in the '33 plans, the rear gear fitting (and therefore strut fitting) does NOT line up with the cluster of side trusses where they meet the longeron. The rear ash cross piece is ahead of the cluster, making the gear fittings (and therefore strut fitting) closer together than the upper end at the wing spars. I'm not worried about safety, I have no doubt that it is plenty strong. I wonder if this was an intentional change by BHP, or a mistake in the drawings. Like I have said, I would assume that everyone who has built a Piet has reached this point and noticed the discrepancy. I want to know what everyone has done about it. SHOULD the struts be parallel?? Does it even matter???? It looks to me like if I move the rear fitting back to the cluster (where the F&G and Hoopman plans show it) it makes the rear gear leg have a really flat angle such that I am not sure it adds much strength. Maybe BHP deliberately moved the fitting forward to reduce the angle?? Those of us building the Jenny gear need to figure this out. I know there are plenty of airplanes out there with Jenny gear, what have those people done????Gene ----- Original Message -----

Keep in mind, even if you do stitch the tail (which I do not think is required) you can do single stitches with quarter-sized tapes at a greater spacing. You'd be surprised how much weight you can save in a critical area.Gene ----- Original Message -----

JohnI bent mine around on a vise. I made the first bend to about 45 degrees and then the second about the same, continue bending as best possible. I then used a scrap piece of solid steel, approx 6"x8"x1" thick and used it as a guide and closed the vice on it. I drilled holed in the steel bar and used it as a cutting guide for bolt holes.Dick N. ----- Original Message -----

Harbor Freight has something called a "vise brake" It has a V way on one side and an anvil on the other. It is magnetic and you open the jaws of your vise and put it in place then close the vise on the metal and it bends it. ----- Original Message -----

You can always just cut out the pieces separately and weld the top piece on, which it actually does not need anyway, other airplanes only have the flat side fittings without a strap over the top of the spar. It probably does not add anything but weight anyway.Gene. ________________________________________________________________________________

I can't way I enjoyed rib stitching but I will say once I got set up and hada system, it wasn't bad at all. You can hit it hard and get it done in acouple of days if you're wired that way.I layed the wing nose down, marked all the holes and burned tiny holes ateach spot. Then made up some long straight "needles" from welding rod (orbuy them), got the lights nice and bright, turned on some music andstationed a friend on the other side. Then we just passed the needle backand forth to eachother. By looking through the premade holes, you can seeinto the wing to the needle to the correct opposite hole quite easily. Goesreally quickly.Douwe________________________________________________________________________________

Steve, Douwe, Gary,I'm listening to the Prairie Home Companion as I write this! Sounds like a good idea. Douwe also had some good suggestions. I will follow them all and start stitching in a few days. Gary promised I could get one wing done in 8 hours! The stop watch will be running! I finished covering the top of the wing today. Will shrink it tomorrow and start installing the re-Inforcing tapes. But my wife says we have to go to a performance tomorrow afternoon, damn!Thanks guys,Ray KrauseSent from my iPad> On Aug 15, 2015, at 7:30 AM, Steven Dortch wrote:> > My grandson had the great idea of sending the needle back through backwards rather than trying to hit the hole with a curved tip.
