| Subject: | Sensenich prop for sale |
I have a like-new Sensenich 64 x 49 wood prop that I had on a 6 cylinder Jabiru
3300 engine in a Zenith Zodiac. I think it was around $900 when I bought it new.
I'd like to get $500 for it.
I would prefer local pick-up in Lancaster, California.
I still have the original shipping box, but UPS shipping would probably run
around $100 because of the oversize length of the box.

I wondered the same thing when I saw the aileron bellcrank. I made different ones
using a ball bearing for the pivot bearing and bronze bushings for the cable
clevis attachments. The bearing and bushings are from Aircraft Spruce. The new
bellcrank is a bit lighter than the original. The thickness is the same so
the original attachments can be used with the holes drilled to fit the ball bearing
ID.

I cannot say for the aileron bearing. However, it is certainly true for the upper
rudder bearing on the HD model. I made a new part after three years of flying.
After removing the part, however, I did feel that the part was still safe
(plenty of edge distance and no noticeable fluttering or vibration in flight).

You are a true craftsman. You new bellcrank is a work of art. Do you have a
drawing of your design? It looks like a very good design improvement.
I'm thinking that I will replace the nylon fairleads for the aileron
control cables with pulleys. My hope is to reduce the drag in the aileron
control system, and thereby improve the control harmony. This would not be
a possibility without aileron counterbalance, but with the counterbalance,
it should not present a problem. I'm wondering if anyone else has put in
pulleys?

Hi Terry,
Before you invest a lot of time and money in changing fairleads to pulleys,
I think you should consider another aspect of the "Control Harmony" issue.
The Zodiac XL has HUGE ailerons. This means force applied to the control
stick doesn't require much movement of the ailerons to produce roll torque.
It also means the ailerons work quite well all the down to stall speed where
most spam cans lose nearly all control effect. I believe it is the geometry
and size of the ailerons that makes them feel so stiff in flight rather than
any drag in the control cables.
Good luck,
Paul

Hi Terry,
I do have a drawing I made just to see if it would work. I Printed out a full size
example and cut it out from cardboard. I can't remember if any slight changes
were done when I cut it from aluminum. I don't think so. The drawing was done
in Solidworks. I exported a .jpg file of the drawing so the quality isn't
so great. The bronze bushings are Aircraft Spruce P/N FF303-01. Look under Hardware,
Bushings. They are $0.19 each. Drill the bushing hole in the bellcrank
slightly undersize and press in the bushing. The bellcrank bearing is Aircraft
Spruce P/N BC4W10 (AN218-4). Look under Airframe parts, Bearings. It costs $18.95.
This bellcrank doesn't require any changes to the normal mount and the geometry
is the same as the Zenith bellcrank. Use a washer on top and bottom of
the bearing to insure the bearing housing doesn't rub on the support when you
tighten the bolt.
I don't know how much drag the fairleads would add to the aileron movement. The
cables don't move very far to give full travel. It'll be something I'll check
when I connect the controls.
BTW, the SS rivets work great. Thanks
Louie
