I spent some time in the shop today making his bar mount. I worried back and forth about cutting out the doubler so it could sit right on the beam, and be flush with the fuse sides. I was concerned that it might weaken the nose and allow vibration. But Jerry advised me to do it, and Bob didn't say
not to, so I dug in, and here's what I got:
(I am also experimenting at hosting my own pictures, so please let me know if it shows up okay on your end.)
I have not yet installed the 4-40 threaded inserts, and I'll use JB Weld tomorrow for that.
I shouldn't have made the lower bearer plate so wide, I didn't realize it was wider than the beam and so the cutout for that one is ugly. I'll pack any gaps in that area with tightly twisted strands of CF-tow fibers and CA. The beam is not molested.
In addition to the 4-40 inserts, the bearer plates will be JB'd and fastened with small wood screws to prevent bowing. Now this clamp will fit any of many engines if I decide to swap out the LA.46 for another engine. I'll also place 2 degree nylon offset wedges under the engine tabs.
Thank you guys for your responses,
Rusty
