Pietenpol-List: Gussets and plywood question

Subject: Pietenpol-List: Re: Pietenpol-List Digest: 15 Msgs - 06/18/04Hey, Fellas! (and gals, too, if any), I have read everything I have about wood, and except for one comment that hardwoods are mainly used in block form, I can find nothing about the selection and use of hardwood. I am particularly wondering about the two piecesof white ash in the fuselage, between the landing gear fittings. The plans specify 3/4 X 2" cross members at the floor level. How do you select the wood for these pieces...quarter sawn, vertical grain, yadda, yadda, yadda or what? Could you substitute oak? I'd eally appreciate the help of anyone who has dealt with this problem. Thanks in advance. Don Cooley Fairfield, CAP.S. Wish I could join you at Brodhead, maybe next year!

As I previously said, Im from Argentina. Here is almost impossible to get1/16 plywood, my choices are buy it from Aircraft Spruce, Wicks, etc.(reallyexpensive), custom made plywood (we do have birch sheets, about 0,6mm or .0236inches) or use 1/8 cedar marine plywood (very cheap, 17 dollars for a 7' x5,25 sheet) for the ribs gussets. I know that 1/8 has been previously used but,would this add to much weight? What do you think? Another question. Im ableto buy 1/4 cedar plywood for the fuselage floor, but this is just 3 ply. Couldthat work anyway? Thanks.Santiago Morete---------------------------------Internet gratis y que funciona!Tres nuevas ciudades con nmeros locales:Escobar, Zrate, CampanaQu espers para navegar bien y rpido?________________________________________________________________________________

1/8 plywood for the rib gussets will not add any appreciable weight. Beware ofany changes this may require of the metal fittings for the drag/anti-drag fittings.If the 1/4 cedar plywood you have is also marine grade plywood it will work justfine.Greg Cardinal in Minneapolis ----- Original Message -----

Santiago,You may want to investigate using fiber/cardboard. You'd have to research it,but my 83 yearold AP mentor tells me that many of the old certifiied aricraftused like a fiber (actually paper I think) board, as gusset material.walt evansNX140DL ----- Original Message -----

Why can't we ship it to you? Maybe cut a sheet up into 2" or 4" strips or 8 1/2X 11" pieces and mail them? Or even 11" X 17"....both "standard" envelope sizes....I know that's not optimum and there will be some waste, but a bit ofplanning could eliminate a lot of that waste.....I know that doesn't help with the leading edge covering maybe this approach wouldwork?Let me know if that works for you and I'll go get some, cut it into strips (orsomething like 8X10" pieces) and mail it.....I would think that your total costwould be MUCH less than the Aircraft Spruce/Wicks route.....Am I missing something? Seems like a good approach.....Jim in Plano..... ----- Original Message -----

Aeronca used cardboard gussets and years ago if you wanted to fly a set of thesewings you had to replace them with plywoodas they disintegrated over time.Al Latham ----- Original Message -----

Subject: Pietenpol-List: Gussets and plywood questionOk. Thanks Jim!!! That sounds very interesting. I dont want abuse of your generosity,but, if you can send me these little pieces, I will appreciate it verymuch. If you agree, I will contact you at your e-mail address. I am not reallyworried about the leading edge plywood cover. Probably I will use aluminum orjust install false ribs (like in that beautiful yellow piet). Thanks again.Santiago---------------------------------Internet gratis y que funciona!Tres nuevas ciudades con nmeros locales:Escobar, Zrate, CampanaQu espers para navegar bien y rpido?________________________________________________________________________________Date: Mon, 21 Jun 2004 12:41:15 -0700 (PDT)

For what it's worth -- a 1/2 sheet of 1/16 birch is about 4 lbs -- cut upinto 12" squares, it's a package 1" thick -- It will ship to Argentina inabout 10 days for $26 via "Airmail Letter Post".Mike (who once shipped a bicycle wheel to Slovenia!)Pretty Prairie, KS ----- Original Message -----

Hi:Yes, it has been done before.Thats what I did; routed out a groove in the bottom of the ash cross piecesand installed the assemblies before I put the luan plywood floor piece inplace. This reminds me of another method re the floor. I temporarilyattached the ply with screws and fitted in place; the marked out thelocations of the rudder bar post and the front rudder pedals and installedthem on the ply before putting it in permanently.One mistake I made was making the LG brackets per Bernies dimensions;should have made the lift strut lugs longer.Just another way of getting there.See ya'll in Brodhead.Lou Larsen----- Original Message -----
