Re: strut attach fitting angle

Yes. While I was still working on large a/c we always used the aviation equivalent to your polysulfides, patches, hardware, etc. When I worked small a/c you didn't see it much, except in fuel tank areas.

Personally, I think it would be a good idea on a wood a/c.

Re: strut attach fitting angle

I'm sure you noticed, but Ken didn't use the steel straps from side to side (fitting to fitting) shown on the plans. He didn't think them necessary. This last spring while I was finishing the repair to the tail longeron, I pulled the landing gear/lift strut attach fitting bolts out, one at a time. T...

My mistake! Yes, you DO want your strut tabs lined up with the strut angle! N34KP has it's strut tabs on the fuselage bent to line up with the actual strut angle. I was just looking at my set of plans and I don't see any angle noted. Ken bent his to the angle needed to be in line with the struts, as...

Re: strut attach fitting angle

N34KP has the strut attach fittings as drawn on the plans, with plywood strips on either side of them, That is how Ken Perkins built it. It's worked fine for 20+ years now. Personally, when I built one I will attach them inline with the struts.

Not a good idea at all. Twisted one way you open the lay of the cable and expose the insides to grit and dirt. The other way you tighten the twist and with the flight loads overstress the cable.
