[Rhodes22-list] Boom coming loose from the mast

[The Rhodes 22 Email List]

This also happened twice on my R22
Stan was surprised that it occurred and recurred.  But the boom has
remained secure for two sailing seasons since I replaced both the lockout
and the bolt with a  stainless steel aviation grade (AN) bolt and (AN)
castle nut. (AN) bolts have a hole drilled  through the threaded shafts
diameter near the threaded end of the bolt.  When the bolt is threaded
through whatever it is to secure and the castle nut is screwed on until it
is between the bolt head and the drilled bolt shaft hole, a stainless steel
cotter pin is inserted through the bolt staff's hole , preventing the
castle nut from unscrewing itself.  Of course the above would be instantly
clear to you with a few photos but I am away from home with none to send
till later in the week, along with hardware sizes and dimensions used..
Try looking for AN ss bolts and castle nuts in AircraftSpruce.com and
Wicksaviation.com or Wicks.com- these catalogues should have photos, as I
recall.  This repair can only be done with the mast down so you are able to
slide the black -plastic-block -inside- the -mast- assembly out of the foot
of the now horizontal mast.  I lost a month of sailing season before last
with the mast down while ordering and reordering AN bolts  til I got one
just right-difficulty was finding a bolt with right length and with the
cotter pin hole in just the right spot. You will save much time and trouble
if you are able to drill a cotter pin hole through you existing bolt- then
you need purchase only a castle nut.
