Oh...and as for the 2nd part of your question.....Douglas Fir is what I plan to use for my spars.... In keeping with the way several other Piet builders have done, I am dropping the thickness from 1 inch routed spruce to 3/4 inch solid Douglas Fir....I still use the same wing hardware dimensions but use plywood doublers to fill out to 1 inch in the attach fitting areas. This also requires use of 1/8th inch shims at each rib (if you are using upright braces next to the spars)......Terry B________________________________________________________________________________

Im not speaking from experience, butfrom differentdiscussions I have read in this group. keeping theweight off is a very important,widely excepted, truth.and by using spruce versus douglass fir is one way ofkeeping weight off. I should be recieving my spruceanyday from mccormick lumber,madison wi. all thespruce I need for the piet was $389.00. At that price,would you be saving any more money buying douglassfir?--- BARNSTMR(at)aol.com wrote:> Oh...and as for the 2nd part of your> question.....Douglas Fir is what I plan > to use for my spars....
