Pietenpol-List: Ply spar question

Subject: Re: Pietenpol-List: Ply spar questionDan,That built-up spar seems like it would be plenty strong to me (eyeball engineer). I am wondering how it will come out weight-wise. I went with thefull 1" thick and then routed. If I had to do over again I would not do this. What a waste of beautiful spruce that ends up in chips on the floor!! I threwbig bags of spruce chips away that day, not to mention an incredible amount of work. How will you splice the 1/2" ply together since you need about 13 1/2 feet per side of a 3-piece wing? The DAR won't say anything about that spar. Besides, you as the builder have complete control of what you use, andyou don't have to prove anything to anyone. After all, it's only your neck during the 40 hour fly-off period. I guess they figure that's enough time fora catastrophic wing spar failure to occur (don't mean to scare you). :)Dan HelsperPoplar Grove, IL.________________________________________________________________________________

Subject: Re: Pietenpol-List: spoke holesJim,I am not very knowledgeable when it comes to the sizing of wheels and tires. I see on the Buchannan's invoice, line item #1, the Sun WM2 (1.85) x 21 rim. OK, the 21 refers to the overall rim diameter right? What does the 1.85refer to? Is that the measured rim width? Your tires are 3" wide at the widest point correct?
