Dual yokes completed

Thanks

I found a somewhat local supplier as well as a local tractor supply (Farm and Fleet) that carries them. I will be making a trip tonight!

Also found a pair of yokes on Ebay I won for $30.00. They are EADS Sokata yokes but should work fine.

I will send some pictures once finished.

Thanks again!

Thanks Dieter,

I'll try to understand.

Ken.

It can easily be adapted to a single yoke setup. Thanks a bunch for sharing. Now I just have to find where to get those pillow blocks.

McMaster-Carr out of Chicago has all sorts of parts like this. They also have precision slides, millions of different bearings, etc., etc.

Nice job on the yoke setup. Looks great!

Ken,
As you know Im not a Boeing guy but Dang Sir you nailed that better than any other design I ever saw before in all my years in this hobby. Great job! Just wondering how are you managing the pitch a Potentiometer I figure?

Thanks Tim. I noticed after coming up with this design that I found another builder with the same idea of using drawer slides. He was building a Baron B58 but using all metal construction (he was obviously an engineer of some sort). So these ideas must be out in the ether waiting to be plucked!

Yes both pitch and roll are using pots. I've only today completed both mechanisms along with some aileron stops so the yokes don't spin out of control. New pics will be added to the photo section soon. Once again I stress; I cannot describe the smooth but slightly dampened feel of these yokes. I went flying last week in a C172 and mine feels so much better :)

Dieter,

In your drawing, that only puts angled tension on the yoke shaft from what I see. Is that how you had meant it? Perhaps I'm not reading it correctly.

Damn you guys are smart,
Like they say if the girls dont find ya ya Handsome they can sure find ya handy lol :) it just so happens they find us airbus guys both but hey handy is good too :) Nah jjking I go to guys like you to ge my stuff made like that :) Keep up awesome work.

Ok, I see what you mean. I have a similar idea on that but its a bit more complex. Mine has the advantage of being as flat as possible.
I'll re-draw it and post it here.

Hi Ken

I'm still not sure if I understand how the yokes work. I am a daily visitor to your webpage. I haved looked at all the drawings and read everything on your dual yoke setup.As I can see you are using pillow block bearings, right.If you push the yoke forward or move them backward will the shaft that goes through the bearings not slide through causing the piece of wood where they mounted on just to stand still and have no effect on the other yoke? Sorry for bothering you with this question, hope you guys can help me understand.:roll:

Thanks

That's fine Ralton,

It is often difficult to explain all details with static images and text so I'll try to give you more detail.

The two yoke shafts are locked into the bearings with grub screws so the shaft only rotates in the lateral plane (aileron movement). The two yoke shafts and bearings are mounted onto a base timber section (white melamine) which moves back and forward as one when you push and pull the yokes for pitch (elevator movement). This base section is mounted on two heavy duty drawer slides to provide this coordinated movement. Springs then provide elevator centering.

Think of it as a large desk drawer with your two yokes attached to the front, when you push and pull the drawer the yokes move in and out. Mine of course is much more fantastic and marvelous than this ;)

I hope that explains adequately.

Ken.
