These next pics are pretty boring but is what is needed to be done to prepare for the wing build. The center wing of the three panels will get built first. All three panels will have a 'D' box LE and the rear spar will be flush to the bottom surface and it will have an inverted 'T' section. The bass TE and center section spruce spars were cut to length. The stack of ribs were taped together and trued using a 'T' bar sander. The TE and spar locations were marked then they were cut using the table saw. The upper spar notches required that packing be put on the table of the saw to maintain alignment. After this was done a 1/2" hole was drilled so the CF sockets and joiner tube will fit. The hole was slightly enlarged using a rat tail file so the CF socket would fit. I think it is a 'metric' item. They'll get nice packing so that epoxying them together with the spars and shear webbing will create a nice unit that should be stout enough for vintage style flying. (Did you like my wording TomP?
) The last pic shows the tools for the work except for the table saw and drill press.
Guid nicht!

No, no, NO... Jeremy... thank YOU! I finished the fin. The pics don't show a dowel let into the fore portion of it. This dowel will help anchor the fin to the fuselage. Here are a few pics showing the ply cut and put on one side plus the finished item with the rudder. The second pic shows the rabbeted LE with sheeting stepped onto it. On to the wings!
OÃche mhaith!

Mark9- thanks for looking at my 'clunker' and thank you for the compliment! It's funny but as a youngster I was enthralled with jets and WWII warbirds. As time has gone by I have learned to appreciate older designs like WWI and Pioneer birds. The feats of the homebuilt racers of the '30s has taken hold along with sailplanes and vintage sailplanes for the past 20 years or so. I can't get enough of them!
