Is it possible you over torqued the bolts and weakened them? Since this
is the first failure of it's kind, I have to suspect something damaged
your bolts.

It is the stock TW that came with the F1 kit.
The wheel, wheel forks, assembly, etc all seem OK, even after
dragging along the runway on it's side. Just those dang bolts, and what
ever I did to them, that were the culprit.

Years ago a friend of mine with a RV6 only drilled one hole and installed
one bolt in this location. He did not feel that two bolts would be needed.
A year or so later he was taxiing on the ground and turned the airplane to
shut it down into the wind. The tail bounced into a slight depression and
the one bolt sheared like butter. Of course he installed two bolts after
that and had no problems. The RV 6 is much lighter than our aircraft and I
can see how these bolts could shear. This may be a one time occurrence,
however I see no downside to installing better quality bolts at that
location.

What about the bolt that goes through the fuse weldment and holds the
tailwheel spring on? I dont know about the F-1 but my HR II just has one AN bolt.
This bolt gets the same twisting forces as the bolt(s) securing the tailwheel.
I think I will put a high strength bolt in there too.

This is typically a =BC=94 bolt. Some use a tapered pin here or a
larger 5/16=94
bolt. The key here is to get the hole drilled properly the first time
and
to keep the bolt tight. If it gets loose the spring tends to work back
and
forth and oblongs the hole in the weldment. That is when you drill up
to a
larger size bolt.
