hey rudy,
thanks yeah i see it now, that's good.
what is the plastic? solid slippery smooth plastic machined or just
drilled by drill press?
the smaller boats would simply bear directly to the tubein which is
the top of the shaft.
Or is there no tube because it could bear shaft to plastic
block.
Well as usual, my bearings are tight and stuck mast , so bit more
work there.
See
Doug

Hi,
If you mean the space between the cheeks
of the rudder box,
that is where the black plastic blocks
holding the bearings go (see last photo).
Through the cheeks and the bearing blocks
a sheer pin is holding things in place.
So there are two sheer pins taking turns
acting as pivot or sheer pin depending on the direction of the
boat.
regards,
Rudolf

Hi George,
I never found the 270 degree
rotation limiting.
With the original design you
could see the rudders very well, so it was hard not to
notice which way to turn in a shunt.
On Arttu's boat with in-hull
rudders I screwed up when I 'shunted' under engine
power.
Only the rudder shaft is
visible there, and dispite the fact there is a clear mark
showing the front of the rudder I managed to
turn one rudder the wrong way.
But I must say that this wouldn't be a decisive matter for
me in choosing a type of rudder.
You can get used to lots of
things and shunting does take some time to become a natural
action.
Hopefully we will get BD in the
water by August and see how these new rudders
work.
Regards,
Rudolf

Hello Rudolf.
Was the limited rotation of the original
rudders a problem and did it contribute to your
decision to go to the new design ? Do you get
used to the 270 degree rotation or is it something
you have to remember to rotate ruder in correct
direction each time you shunt ?
How soon do you expect to complete the new
rudder system and get boat back in watter for
testing ?
Any additional pictures you post as progress
continues will be greatly appreciated.
Good luck with your project and Happy
sailing,
George Kuck
