REFLECTOR: Elevator counterweights, inboard

[Alex Balic]

Grigore-

 

Do you have the ball bearing modification on the elevators? Maybe it is
standard equipment now, the hardware would be different from what the manual
shows if it is the case and the manual has not been updated..

Many thanks for your answers on primers.  I will consider some cold weather
accelarator for 545, but in the meanwhile I'll work on parts that don't need
higher temperatures, such as the elevators instalation.

 

I was just installing my inboard elevator counterweights and ran into some
problems.  I guess part of the them are due to the fact that the manual is
not updated together with the kit.

 

First, all the parts listed in the table at the begining of section 3.5.2
(positioning torque / counterweight arms) have completely different numbers
from those of the parts that I received with my kit in the little plastic
bags.  Therefore, I had to go by descriptions, pictures and by
trial-and-error. 

 

Second, all the screws mentioned in the installations in Sec 3.5.2 are
MS23694S-59, including those attaching and weights and those attaching the
aluminium bushing in the torque tubes to the elevators; however, they were
too short for the aluminum bushings, so I took the liberty to use
MS23694S-70 instead, which appear to have the right, larger length.  I'll
call Velocity tomorow and ask them whether that was OK to do or not, but I'm
sure that MS23694S-59 cannot go all the way through those large aluminum
bushings. 

 

Third, my "torque tube spacer assembly" bag contains indeed one spacer and
one bolt, but the bolt is AN4-10A and the spacer has a 1/4'' hole through
it.  On the other hand, the manual mentions a large stainless 3-1/2'' screw
that goes through both weigths; the weights have 3/16 holes, so I'm assuming
the 3-1/2'' screw would also be 3/16.  I was really expecting to find the
3-1/2'' screw together with a spacer with hole 3/16 in the torque tube
spacer assembly, not what I found.  Am I doing anything wrong here? 

 

Finally, while the countersunk MS23694S-59 look nice on the outboard
counteweights because they really sink in the arms, they look kind of ugly
on the inboard one ... Are they supposed to also be countersunk where they
attach the inboard weights as well? 

 

Thank you,

Grigore
