I will be removing the control yoke for the shaft to refurbish them.  I assume they are magnesium having read the older posts.  Any suggestions from those of you who have done the same?  How do you remove them?  What is used to clean and polish them?  Any particular treatment yields the best look for them?  Paint, polish, wrap...?

Willie, what dash Stinson do you have?  The dash 3 yoke is attached to the shaft with a steel pin which goes cross ways thru the yoke and shaft.  I believe earlier dash airplanes had a nut (hidden under the plastic nameplate) which secured the yoke to the shaft.  I had my yokes powder-coated, but you could paint them.  Yes, I think they're magnesium.

My dash 1 yokes were not easy to get off the shaft, but some heat and nudging helps. The shaft is threaded at the yoke end and there is a nut to help secure the yoke, however the yoke also has a key way that is aligned with a key on the shaft. See the pic attached. 

I suggest removing the name plate on the front of the yoke to gain access to the nut, remove the nut, then use some heat on the around the yoke and use a plastic mallet to drive the shaft/key out of the yoke.

It is a -3. I see the pin. Do I need to heat it, is it pressed on? Thanks, Willie.

@willie-spence  The pin for the yokes is a press fit. I recommend pulling the shaft from the u-joint under the panel so you can place the yoke on a suitable steady surface to drive the pin out. A proper sized drift/ punch and a hammer should make short work of it. I tried driving the pin out with the shaft still in the plane but decided that was not a good idea. I was shaking/ vibrating the instruments so bad I feared damage.

Then just bring them to me, Willie.  I’ll prep, epoxy coat, base, then clear them!
