[Rhodes22-list] Rudder problems

[Kroposki]

Saroj:
	By swivel do you mean right to left or up and down.  With all
those graduate degrees, surely you can describe this problem in a more
defining way.  Take Slims approach and draw a picture.

Thanks Bill and Michael.

<<by non swivel, do you mean frozen or just very hard? Did the painters
take
it all apart when they painted it?>>
>>>>>Don't know for sure until Monday.  Doubt it though. The tiller was
off
already -- pretty sure they just removed the bolt that holds and swivels
the
rudder. All of it was painted, including the part that goes inside the
casing.  Before I took it all apart, it would move about 30 degrees on
its
swivel, but it was impossible to get all the way down.

Michael, you suggested sanding the rudder down which makes sense except
that
it would remove all the paint and I have no idea what it is made out of
(i.e. is it sandable).  It seems much to curvy and heavy to be wood.  It
also has had cracks in it along the center seam which I have had epoxied
and
glassed over.  As I mentioned there are further cracks where the rope
holes
are which I didn't realize until Friday.  Water poured out of one of
these
when we took the rudder off the boat.  Can't be good for the inside of
it.
Maybe that's why it is so heavy.

One source of the problem is that the boat WAS in Chicago - damp; then
in
Arizona - dry, then in Montana - dry; now in Virginia.  However one
would
think that the spacers would be expanded now in a damp climate, not the
other way around.

Before I took the rudder entirely apart, I first loosened the swivel
bolt,
still too stiff; then I loosened the lower bolts on the back spacer,
still
stiff; then gradually worked my way up.  At no point was I able to get
the
rudder to move freely enuf to be able to pull it into the up position or
fully extended by anything but brute force.

I'm pretty sure the casing is made of aluminum, but since I don't know
what
grey pvc looks like I'll have another look at it today and try to
determine
that for sure.

The spacers appear to be pressure-treated pine or some other soft wood
with
no apparent coating on them.

I realize that in my thoughts about using washers to create additional
space, I was assuming that all washers are stainless steel.  Now I'm
wondering if there aren't aluminum washers.  I'll check around today.

It bothers me a little that the wood spacers are completely uncoated.  I
think my first step ought to be to varnish the spacers.  4 coats or so
will
build up their thickness and may be enough to solve the problem.  I will
probably have to replace the bolts as they appear to be "just" long enuf
now.

If the rudder still does not swing freely, I'll see about washers.  I'll
also inspect the rudder more closely today and see if it is warped.  If
so,
I'll see about getting a new one from Stan and maybe some new spacers as
well.
