Hello John,

Thanks for figuring out what I was trying to ask the “List.” I think I understand most of what you described, but where did you mount the “saddle” on the boom. Was the Saddle haft the circumference on the boom tube, and riveted to the boom?
What material did you use, “ In addition to bracing the tail post” for this bracing?

Thank you very much,

Nick Cassara

Nick C/Kolbers:

I included the two previous photos of my lower vertical stabilizer and tail
post braces. At the forward end of the lower vertical stabilizer the 4130
saddle is visible.

We fabricated the lower vertical stabilizer on my MKIII from 4130 because we
knew this was a high stress area during ground handling/taxi. The saddle
was cut out of a section of 4130 tail boom ring, welded to the forward end
of the lower vertical stabilizer and pop riveted to the bottom of the tail
boom.

I did it a little differently from John. I am sure that he and Jim did it right, I modified an existing screw up and just drilled through the ring at the back of the tube. The ring is under no stress, and a new hole in it isn't going to hurt a thing, so I could find no reason to make it any more complicated than necessary. I used some alum tubing for the brace. Just be sure you don't split it when you flatten the ends. Your options are open and do as you think right. Larry

Here is what we did on Ed's Firestar II, just a length of 1/8" aluminum flat stock on each side. Drilled one new hole on each side of the steel ring, and used the existing bolt that secures the tailwheel strut. I will be doing the same on my MKIII this winter.

For pilots who like that.... [add-on look]..... How about this short field landing tail-hook device. Wink
