Substitute for Fox 2" bellcrank

[bill bischoff]

Need a Fox 2" bellcrank but can't get your hands on one? A suitable replacement can be whittled out of a Brodak BB-379 bellcrank instead. Put the leadout holes 2" apart, and put the pushrod hole 3/8" from the center of the pivot. Lay it out directly on the bellcrank, or make a pattern first if you plan to do more than one.

Where's the "like" button?

you could put buttons on the bellcrank if you like.

Well played Mr Bischoff.....
Cool info, thanks. I've recently been interested in making a few button bellcranks and a few monoline connectors while I'm playing with new machine shop tools.

This is good info especially since I used my last Veco 2" bellcrank on the last Sport Goodyear I made.

Has anybody considered retaining the self-centering feature of the Brodak bellcrank when making the 2"?

I personally don't care for the "feel" of it. If "bellcrank" neutral isn't lined up with handle neutral and elevator neutral, the plane can feel unstable and won't groove properly. I learned this long ago with carrier planes and their self centering 3 line bellcranks. Conversely, if everything is in harmony, I suppose it could actually impart a more stable feel. If I were to try it, I think I'd leave enough extra material on the bellcrank to revert to the "straight across" leadout position if I didn't like it.
