Default Welding question


At http://www.taylorcraft.info/tcraft/proj207.jpg we see a restored
tailsection.

The bushing appears to have first been welded to a plate, and the plate
in turn welded to the tailpost. Is that what was done? Is this done to
help with alignment of the bushing? - Mike

That's one reason.
It is a lot easier to assemble (weld) the bushings jigged up solid on the
bench. How would you align and clamp up the bushing to the tailpost and
still be able to reach the weld area?

Often this apporach is taken on new construction just because it provides a
bit of space to allow for fabric without binding.

If the bushing were dammaged somehow and needed to be replaced, this also
spreads the new weld to the tailpost out over solid tube.

Not to worry. It looks like a good repair (from here anyway).

I would guess that the objective was to reinforce the tube where it is going
to get localized loads. The extra thickness should help reduce the tendancy
to "kink" at the point that the load from the rudder is applied up in the
middle of the span of the tube.

This looks like one of the three rudder hinges attached to the vertical
stab. And some nice repair work where rust does its damnedest to keep
you from flying. The 4130 steel part you call a "bushing" is supposed
to contain a pressed in oilite bronze bushing inside, for easy turning
of the rudder. When the bushing wears out, you just press it out and
replace it with a new one, which I have done on occasion.
