Regarding the wedge blocks, I believe they are only required at the two locations shown, as reinforcement for landing gear attachment. Some builders have opted to use lightweight balsa filler wedges in other locations, to avoid water collection in the pockets (not a bad idea).- Regarding plywood, one important feature of Aircraft grade plywood is that it is manufactured using waterproof (actually boilproof) glues. This will prevent the plies from delaminating, should the wood somehow become soaked with water. An economical alternative to Aircraft grade plywood for the fuselage sides is the use of BS1088 or BS6566 Okoume Marine Ply (Okoume is a mahogany-like tropical wood).-While it is not quite as strong as Aircraft ply made of Birch, it is apparently strong enough for this purpose, and is manufactured using waterproof (also boilproof) glues. In addition to the lower cost, it is also lighter (in weight, as well as color) than Birch, and available in 4' x 8' sheets. - A couple of sources for Okoume Marine Ply: - - http://www.noahsmarine.com/ http://www.boulterplywood.com/ - Bill C. - -" rel=nofollow target=_blank>http://www.matronics.com/Navigator?Piet ... cs.comllow target=_blank>http://www.matronics.com/contribution-_________________ - -http://www.matronics.com/Navigator?Piet ... ronics.com -http://www.matronics.com/contribution - --http://www.matronics.com/Navigator?Piet ... tribution-" rel=nofollow target=_blank>http://www.matronics.com/Navigator?Piet ... cs.comllow target=_blank>http://www.matronics.com/contribution" target="_blank">http://www.matronics.com/Navigator?Pietenpol-Lista href="http://forums.matronics.com/" target="_blank">http://forums.matronics.com_blank">http://www.matronics.com/contribution- - - =0A=0A=0A ________________________________________________________________________________Date: Thu, 27 Aug 2009 23:50:55 -0500Subject: Re: Pietenpol-List: Re: ASSCO,inc

Jorge,I'm not sure if I understand your question, but if you are asking whether Okoume Marine plywood is okay to use for your fuselage sides, the answer is yes. Many Pietenpols have been successfully built with this plywood used for the fuselage sides.Bill C.-----Original Message-----

One more thing I would not use Okume unless I coated it with epoxy, it's softand you can dent-it with your finger nail, it however soaks epoxy like a spongeand this increases it's side hardness and abrasion resistance.On Wed, Aug 26, 2009 at 3:24 AM, Robert Ray wrote:In the South east you can build out of poplar if you like, you can buy it for a buck a boardfoot, I'm thinking of building out of baltic birch although not boil proof it's stronger and moreflexible than 1088 Okume, probably twice as strong per deminsion and it's CHEAP.The epoxy I'm using will not pass a boil test either. The birch I boil tested the naturalwood fibers broke down just as bad as the glue joints. What I worry about is not somuch a boil test or a good soaking it's high humidity over time. I have a piece of balticbirch on a truck topper I built it's been exposed to rain several times and hasn't delaminated yet.It's shock resistance is amazing. Birch rules, the boat builders rate marine plywoodstrength in this order DF, Meranti then Okume, the Jodel originally was built ofOkume but many are now using GL aircraft birch. I think Meranti is a little cheaper than the Okume but again heavier but stronger, it is more durable and less likly to rotthan either okume or birch.I would not use anything but 1088 if I used Okume I have bent it on other projectsand I think it's 6056 and it will break where it's inner ply's are spliced.If you want to know about okume go to kayak building web sites and there you willlearn.

This may not be the best, but Ill include my favorite. Its simply three, one footpieces of chain each cut into three, four inch pieces. These are joined bya hefty brass hook with a ring to tie to. While youre in the hardware storebuying the chain (theyll cut it for you) purchase nine of the largest nails theyhave (check to assure theyll pass through the links). To get fancy, pickup a fence hammer which also works like pliers to extract the nails. Add threepieces of good rope (also from the hardware store) and place it all in a bag.See enclosed.

But, the card reader that came with the lowrance unit is proprietary and it no longer works, so I have no way to load the file to my flash card. Complicating things further, the flash readers have multiple drivers for different readers, and I don't know which one to use because the sticker fell off my reader long ago. Of course, the web site still takes my money.
