Hi all .. looking for some feedback, please.
With a 4130 steel tubed fuselage, it would follow that mounting lugs would be the same material. However, since in most cases, the lugs being supported on one side, .. more bending potential .. would substituting milder, softer steel be a better idea?
Using a specific example, on a Tailwind, the horizontal stabilizer's forward fastening point. (See attached image, .. yes, it does specify a 4130 lug/plate). Really, a better example would be where just a single side of the lug would be welded to tube, .. but, I think you get the idea.
In this case, .. if I were to go mild steel. I would use an 1/8" thickness mild steel versus the 16 ga/.059 4130 suggested.
Thanks for any reply.
