Today's progress....boxed in the tail area...
Note to yesterday's picture post... I did replace the lower stabilizer flying wire bracket at the front tailwheel spring bolt and added a bushing for the tail spring front bolt. Started with a chunk of 3/4" OD X 7/16" ID tube. Machined all but a 1/4" of one end to 5/8". Drilled the bracket and welded the piece in. The tail wire bracket thickness was increased to 1/8". The 1/8" thick bracket is recommended for the PA 18... Todays pain in the arse piece was the center rear seat bracket. Bought the seat mount brackets taken from a 1959 PA22 from Steve's Aircraft. Lots of grinding and fitting. Need to remove the now not used hydpdrosorb rear bracket to finish welding in the 7/8" tube.

Any idea what the weight difference is with this Trimmer mod?

While I was doing welding on my fuselage this winter, I increased the size of the bottom access hole, making it less of a,"hell hole".

I just finised repainting my fuselage after patching/replacing about 25% of the fabric. I will look more respectable hanging out around Gilbert next time! Back to wiring.

There is more steel in the gear legs. I haven't tossed the left gear yet. Will weigh the original narrow gear and the supercub gear including the oleo strut for one side... Be nice if Ryan Air storage would deliver the freight! Adding seaplane left door...steel, right door steel...then the heavy polycarbonate for the doors and skylight. Trading the nicer heavy interior panels for Kydex...and fabric. But...ordered leather for the front seats. Adding more metal to the wings and crosswind STOL wing tips....Empty prior to rebuild was 1024 pounds. When I get to the panel and wiring need to loose weight there, something like 84 pounds of wire instruments and general stuff. Hope to be close to a grand...wish I could use the glass panels for experimental!

Today's progress. Five hours in the shop. Spent most of the time scraping and sandblasting the bottom right seat frame. The thing was covered in goo. Some areas had a layer of black silicone like stuff? Printed up the seat mount drawings from the SWPC disc. Then made a fixture from one inch by quarter inch flat bar to position the front center seat mounts. Will tackle the left seat tomorrow and the outer seat mount brackets.
