Attached is a file showing the construction method I have elected to use for the
wing ribs. The ribs are constructed out of 1/8" plywood with 1/8" x 1/4" plywood
cap strip stiffeners glued to each side top and bottom. Although this makes the
rib cap strips 3/8" thick, the ease of construction ( glue 4 pieces to the rib),
the dimensional stability, and the added strength pay off. The best part of all
is it takes a half hour to cut out all the ribs - I had them laser cut from a CADD drawing.
Construction is continuing on Hatz T3, #723.
The image shows one rib and the separate 1/8" ply cap strips. The laser cutting
made the cap strips possible. They claim that all cuts are within 0.002"!!! Fits
like a jig saw puzzle.

I have kept up with your web page many months now. VERY MUCH ENJOY IT!!!
I am building Hatz #723 here in the great state of Washington about 30 miles
south of Lorin. It seems I call and visit Lorin to talk Hatz just about as much
as I visit your web-site. I will send pictures of my progress as soon as I can find
time to scan them in and write a narrative.
