Rudder accessories. The 3 pieces on the lower half are the rudder
arms which, with the use of a linkage arm, will connect the rudders together.
Also, they're the cable's pivot arms. The other pieces get attached
to the trim wing (shown below) to hold the rudders in place. They
allow the trim wing to move without affecting the rudders movement.
Rudder mounts attached to the trim wing.
There will be a spacer under the linkage arms that will bring the rudders
all the way up to the trim wing. For now, I'm just testing the fit
and movement.
Ahh yes, my favorite linkage, an Aluminum yard stick. This is the
ONLY item I buy at Wal-mart. They work great for connecting rudders,
and make it VERY easy to drill holes in the right place for each rudder
:-)
I hooked up one of the Push/Pull cables to test out the throw and rudder
angles. I think I settled on 2" +/- out from the rudder pivot.
It gives me better than 50 degrees of swing each way.
Here's the control stick. The EMT will go under the seat to meet
up with the cables. The steel bar at the end will allow for the right
amount of stick to rudder movement. I used a cheap Mt. bike flat
bar for the stick. They're light, strong, and comfortable.
The trim wing cable will attach below the pivot on the stick for forward
and backward movement. I bought a shift boot to go over the hole
in the seat for the stick.
Here's the finished product. I've welded on a chunck of steel to
mount the cable clamp to for the trim wing. Oh yeah, I've scrapped
the shift boot. It wasn't large enough, and made it hard to move
the stick.
Rod ends and a bolt connect the cable to the arm for steering.
Using furniture clamps, I'm able to figure out where best to mount the
cables at rudders.
