Hello everyone, I went to my local VERY high end lumber yard and found that theyhad about 50 16' long spruce 1x12. There's a lot of work in picking throughbut there's definitely useable wood. And get this 23 dollars apiece. I alsoasked if they could get clear and they said the best they could get is #1. I'ma carpenter so I know something about wood, but my question is, can ponderosapine or radiata pine be used? They have a very good selection of doug firalso. If doug fir is used, where can you downsize to eliminate some weight, orcan you? Also, one last question. Since only recently catching the piet bugand short on funds right now, where can I find a description of the parts thatI don't know, like spars and longerons and such. Thanks for your help. I'llsee y'all in the skies somedaySteve________________________________________________________________________________Date: Wed, 08 Mar 2006 16:12:08 -0500

Steve,If they don't call it Sitka, it is probably White spruce. White spruce is about93% as strong as Sitka. I used #1 White spruce for my Piet (has NOT flown yet)except for the spars, longerons, wing tip bows and 3 uprights in the fuse sides,used doug fir, full size, for these things.If you can do your own grading that spruce sounds like a good deal.Skip, see you all at Sun n Fun wood shop----- Original Message ----- found that they had about 50 16' long spruce 1x12.

Hi SteveI have also been keeping an eye open each time I go to the lumber yard. Maine seemed to have a lot of good choices and I bought some 2x8 x 16 ft and stored them in my garage. I'm currently in Ontario oregon and have only seen 1 2x6 x8 that was suitable. Most of the wood I have seen out here is new quick growth stock but much more fir available than back east. Where are you located?Steve G>From: "The Schuerrs" >Reply-To: pietenpol-list(at)matronics.com>To: >Subject: Pietenpol-List: I wanna build>Date: Wed, 8 Mar 2006 12:50:50 -0600>>Hello everyone, I went to my local VERY high end lumber yard and found that >they had about 50 16' long spruce 1x12.

Dear DJ and the Rest of The Guys:I've been following, with great interest, your discussions of airfoils vis-a-visGN-1 vs. Piet. But my initial question still stands unanswered: Why are therear cabane struts of a GN-1 (plans) longer than the front ones-thereby positioningthe leading edge of the wing at a, presumably, negative angle of attackduring level flight? Do you fellows think I should keep to the plans, or alterthe dimensions of the cabanes to, at least, place the leading edge of thewing in some degree of positive angle of attack during level flight?Yours sincerely,Alan ----- Original Message -----

Subject: Re: Pietenpol-List: Piet vs. GN-1 airfoilAlan, If you take a rib and put flat on the ground it will have angle of incidence because the thrust line runs from the rear tip of the rib to the center of the radius on the front.

Hi Alan,Changing the cabane length won't affect the airfoil AOA. It will change the fuselageangle relative to the airfoil.GN's appear to fly noticeably tail low compared to Pietenpol's.I'm not familiar enough with the GN plans to discuss the merits, or problems, ofchanging the cabane lengths.Greg Cardinal ----- Original Message -----

Mark,Yea, they're both open but Americana is now Grand Geneva and it's a huge place with an indoor water park and some really fine amenities. LLL is still the same.Steve----- Original Message -----

this may sound wierd but front/rear cabane length relationships are not what theyseem when determining AOI.what really counts is the chord line of the airfoil. it's possible that you couldhave a rear cabane that is 10" longer than the front cabane and still have0=B0 AOI. How? if the front wing spar plates were REALLY long and made theup for the difference in length.This is what is going on in a GN-1. The wing spar plates are of different dimensionsbetween chord line and attach point of the cabane. look closely and dothe math and it all becomes clear.DJ ----- Original Message -----
