Hello Group!After finishing my wing ribs, I read a suggestion from BP, in the articla onthe Sky Scout that the diagonal brace aft of the rear spar should be from topto bottom rather than from bottom to top as shown on the original Aircamperdrawings. Is this critical? Could an additional brace be used to reinforcethis bay? It would not be too difficult to add a cross-brace diagonal withgussets, I suppose. What say you?Don CooleyP.S. Happy New Year!________________________________________________________________________________

Don, I think I read somewhere that someone was slipping a Piet in for a landing,and that a diagonal snapped. So Bernard switched it around to put it incompression instead of tension. With my limited knowledge, I'd say leave themthe way they are and don't do any hot dogging after you get her flying.________________________________________________________________________________

Hi Norm, Get ready for some fun! It sounds good to me, but do you reallymean 5 sq. ft. of plywood? I bought a 2 x 4 sheet (8sf) of mahogany plyand I will be a bit short on gussets, but not by too much. I have to orderanother sheet. Your capstrip is probably close, but then I cut my own fromboards and haven't really kept track. There's a list that calls out 500 ft,check this site. http://www.mykitplane.com/Planes/People ... d_List.xls Thisis a wood list from someone here on this list. I'm using staples too. I have a light duty stapler with light duty narrowcrown 5/16" staples. I got mine at ACE, about 8 bucks. The staples areround (versus flat chisel point) and it works great. I used an officestapler at first but it didn't seem to have enough 'oomph' to get thru theplywood. It's quick and easy, takes about 10-15 minutes to remove staplesfrom both sides of the rib when the T-88 dries. And that's about all I know about Pietenpol buildin'...Kent Hallsten Oklahoma CityMaking ribs like a madman________________________________________________________________________________

Sounds pretty close to the way I did it. I'll expand on Kent's commentsabout gusset material--I got a single 2x4 sheet and ran out. I wound upusing a lot of 1/16 inch plywood for gussets on the 1/2 x 1/2 root and tipbraces, and to make bearing plates where bolts would otherwise be in directcontact with spruce members. You'll also eventually need a whole 4x8 sheetfor the leading edge sheath unless you're using cardboard. Shipping costsare less of a problem if you get all of the really big stuff at the sametime.Have fun!Gene HubbardSan Diego with a new motor mount!________________________________________________________________________________

Way to go Norm. I ordered 500 feet of capstrip from AS&S and it's just theright amount (a little extra for mistakes). Worked out perfect. I tried thesteaming part and didn't like it. I just put about the first 2 feet of thetop capstrip in a tube with just plain ol' water for 24 hours and thenformed them on the forming jig till the next day. They were dry the nextday. I formed 4 at a time and only made them every 3 or 4 days. Worked outgreat and you can't get burned. Much safer. They bend just as easily and youdon't have to rush it.It took me about an hour each evening to make one rib. I pre-cut all thediagonals and the gussets when I started the first rib and then glued thefirst side of the rib and let it set till the next day. I then took it fromthe jig and with the same batch of epoxy I glue the next rib's first sideand glued the gussets on the last rib's side #2. Once set up, it was 1 ribin 1 hour per day.I was done in a month.Good luck, it's very satisfying.George AllenHarrisburg, PAGeorgeA(at)PAonline.com(Peitenpol builder) Ribs, horiz. stab & elevators done.>Subject: Pietenpol-List: wing ribs>> Hi,> We are getting ready to order our wing rib material.

Precise workmanship is always satisfying,and you seem to be making an extra effort in one area so as to reducethe time spent in another. (Though if you'd just put the gussets onthe first side, you could have removed the rib without waiting for theglue to dry.) Aside from that, those joints won't do much for theairworthiness of your rib. The verticals and diagonals simply transferstresses from the top and bottom surface to the gussets, which take upall the loads that attempt to deform the ribs, rather than being routedinto the spars. They would do that just as efficiently if you lopped theends off square and left big, triangular gaps between them and theupper and lower capstrips. As many efficiency-minded builders havedone, without any problems.That said, I am fitting the ends of mine as well as I can. Those gapsmay be harmless, but they are aesthetically unsatisfying.Owen Davies________________________________________________________________________________

This method soudns great, but how do you support the rib while the gussetsare glued? How do you keep it flat with all those pins? Also, how do youkeep the gussets from sliding?Thanks,Ken, still getting the fuselage sides together in Austin, Texas, and lookingforward to ribs.----- Original Message -----

The Waco Airplanes ribs were made with squared off ended loose fittinguprights and diagonals in the ribs. Indeed, the load is transferred to thegusset in shear although the gussets are a bit larger. I would make thegussets 30 to 50% larger in each dimension (except thickness) and disregardthe close fit of the uprights and diagonals.chris-----Original Message-----

ButI'd guess that the gussets were bigger on the Wacos becausethey were expected to carry a larger load, not because ofthe way the uprights and diagonals were cut. The Wacoswere just a whole lot heavier than the Piet, and the open-pitversions were probably stressed for some aerobatics.Owen________________________________________________________________________________

That can't help but make a good strong joint. The gusset should be good close fit too. Clamping pressure should not be so heavy that all the glue runs out of the joint either ! Little glue coming out is good sign of proper clamping though.Ever try testing to destruction one of your ribbs ?

The scuffing is needed more for birch plywood than formahogany.Mahogany doesn't seem to "glaze" the way birch does. Couldn't hurt to scuffthe rest of your gussets, but the ones you have should do fine.Owen Davies________________________________________________________________________________

Pietenpol-List: wing ribs
Original Posted By: Norm Decou
Ken,I thought about the difficulty in gluing gussets to both sides at once, so I set up the rib on a couple of soup cans and glued the gussets on one side at a time using small spring clamps to hold them.Rod W.________________________________________________________________________________Date: Sun, 12 May 2002 00:23:36 -0400

JohnLook at the Bowers Flybaby, it uses plywood ribs. The conclusionfrom what I looked into is that the Plywood rib is much heavier than that ofthe traditional builtup rib. A rib that is lighter than that of the traditional method is one that I believe was incorporated in the Longster of the 1930's. It uses no gussets and two cap strips on top of the rib and two on the bottom with the crossmembers sandwiched in between.Bruce________________________________________________________________________________

MessageJack,Did adding brakes force you to use an axle that is longer than the F&G plans?NX18235 is brakeless and is using 1 1/2 X .120 tubing. I have made some horrifically hard landings at 1100 pounds with no sign of axle bending.Greg CardinalMinneapolis ----- Original Message -----

Rick,Yes, the John Deere that WW and Mark Langford suggest.The wing is moved back about 2" (cabanes leaning back).It (flies) (fly's) is flying slightly nose heavy.Probably should move the wing forward slightly 1/2" (1 1/2" leaning back)may be this winter.FYI, I did not take extreme measure to build light, simply build to theplans and weight should not be a problem.Hans.

Pietenpol-List: wing ribs
Original Posted By: "Dick Navratil"
I attached a pic of my set up. I bought a blemished interior door for $5 and set up jig for one rib. After making one, I duplicated twice, now I make 3 at a time. If anyone is wondering, the sockets hold the glued gusset plates in place so I dont have to staple.Dick N.________________________________________________________________________________
