verticle fin to Fus-43 problem
Posted: Sun Feb 19, 2012 11:26 am
I found trouble when hoping to mate the verticle fin to Fus-31 (horizontal
bulkhead) and Fus-43. MAM is missing here IMO, in that it says to keep
Fus-43 flat with the use of a piece of plywood -- no problem there -- but
doesn't say anything about getting the forward/backward angle of Fus-43
correct. Result is that the rear flange of Fus-31 doesn't reach the fin
post, and in addition, the fin front bracket doesn't fit flat on Fus-43.

On mine, this can be corrected by angling Fus 43 just enough so that the
top moves only 1/4", maybe 5/16" forward. That's a pretty small distance,
so the angle -- or really, the distance back to the top of Fus-43 -- should
have been measured. Unfortunately, I will need to replace the Fus-29 skins
to re-do this. Frustrating.
Anyone else have similar problems here? Did I miss something obvious?
