Duncan, Bud,
Thanks very much for responding. Bud your mod makes sense but at this stage I'm
looking for an easier solution. I am currently planning to replace the original
steel plate with an exact copy, re-bonding it to the ply/bid platform and
putting
in a new bolt (I found indications of light corrosion on the bolt at the
point that it passed through the steel plate).
In Graham Singletons mod (PFA 10371) he mentions using 1/8th sheet bent to form
a 1/2" by 1" angle to 'reduce the tendency to bend and crush the plywood/bid
reinforcement'. With no other detail, I presume that this would go on top of the
steel plate with the bolt passing through it as well. I can see how this mini
girder could help spread the load.
I also read in a report (of a tail wheel failure) that six or seven mono owners
had fitted a mod that comprised of two light alloy plates bonded to either side
of a block of Paxolin. This was claimed to provided additional lateral support
for the bolt. The report stated that this mod was approved by the PFA but
I can't find any evidence of that.
Anyone else out there with knowledge?
Regards
Ron
