Sailed, modified, broke, and repaired the sailboat a while. Evenings are getting cooler so Wednesday night I sanded all the epoxy drips off the work table and dug out some zenith parts.
Last night laid out some steel tube for straight support jigs. (Table is on dirt and uneven after a few freeze thaw melt mud cycles) good practice to have some straight steel tubes or beams to clamp to anyways.
Clamp the horizontal stabilizer spars and ribs in place and started going through all my old emails with Roger for dimensions. Drilled pilot holes for the center three ribs and clecoed in place. Need to find or make the angle tab for the outer ones and get them clecoed in place.
Thinking about the skin. .020 with a 1 1/4" radius leading edge. The pipe I had used for vacume forming the rudder isn't long enough for this 10ft long skin. Will need to find a longer pipe which may start getting too flexible or figure out a different method.
