February 21, 2007 ...  UPS delivered my replacement channel today, so I went right to work, fabricating the outer rear spar pieces that I botched up before. This time I was a lot more careful. Both parts turned out much better. This is a photo of the left side; the right side mirrors the left.

February 27, 2007 ...  I made the spar stiffener brackets and cut out the wing mount blocks. I didn't drill the holes in the mount blocks quite yet. I am still planning my strategy on that to obtain the best accuracy. I have been refering to several builder websites and gleaning some great tips which should help. I also made the tiedown mount brackets. All of these parts were fairly easy to make.

March 3, 2007 ...  I fabricated the lower spar angles. These took the majority of my shop time today, as there is plenty of cutting, drilling, and filing to be done. By the way, I found that the drawings call for these parts to be made from 2 X 2 X 3/16 angle material. However, I discovered that the airframe kit "Parts List" specifies that these be made from 2.5 X 2.5 X 3/16 angle. The kit actually provides the wider angle material for these parts.
