I'm ready to attach my walking beam for the elevator controls in my Aircamperand I like to see how others have done it. The original plans and the 1932 Glidermanual show the bearings just attached the the vertical fuselage struts with3/16" bolts. The Skyscout plans in the 1933 glider manual show the bearingsattached to 2'' x 5" spruce blocks bolted and glued to the inside of the verticalstruts. I have seen photos on the web with the spruce blocks, but they wereonly glued an no additional bolts. I've also seen examples of the originalattacment method.I am a little reluctant to drill the two 3/16" holes through the strut since ifthe strut collapses I'll be in a heap of hurt. I'm assuming thats why Berniechanged it on the '33 skyscout plans. What have most others done?Thanks,RickRichard Schreiberlmforge(at)earthlink.net________________________________________________________________________________

Drill the holes and don't worry about it. I doubt if one of those uprights hasever broken because of the holes drilled through it.Greg Cardinal ----- Original Message -----

Just use care to make nice clean straight holes. I also drilled a #40 hole in the top of each of the bellcrank bearings, so I could oil them at each yearly 'Condition Inspection'.Chuck GantzerNX770CG________________________________________________________________________________
