Pietenpol-List: 3/4" spars

In regard to the message from the fellow that received 3/4" spars , I'veheard before that they are OK ( I used 3/4" Doug Fir), but since the ribsare already made with a space for 1" spars, rather than block out the ribs,why not glue a piece of 1/4" by 3/4" spruce to the top and bottom of oneside of each spar to create a I beam effect without routing. That wouldgive most of the strength of 1" spars with a little less weight and it wouldprobably be easier than blocking all the individual ribs. You might alsowant to block out at the lift strut attach points and the wing attach pointsto keep the attachments in accordance with the plans.

"Domenico Bellissimo" That's a good idea, except I would glue 1" X 1/8" to both sides. It's reallyonly the top and bottom inch that gives all of the strength in an "I-beam"spar.regards,Domenico________________________________________________________________________________
