yoke

When I get my plane (PA28R) back from annual each year the shaft connecting the yoke is always well greased with virtually no friction giving the controls a nice, new frictionless feel. Now I'd kind of like do that maintenance myself periodically b/c after 150h it's not as nice... Curious is...

Has anyone here wrapped their yoke or purchased covers somewhere like the photo I included? Would love to do this to my Arrow. I'm just curious as to what's the most efficient/cheapest way to do this? Is there a good place to order covers for them from?

This single yoke came with my plane when I bought it, but I have aftermarket yokes so no need for it. It's well used and I cannot attest to its airworthiness. I have no idea whether it has any value but would be happy to see this find a new home. $20 + ship?

Has anyone ever put bicycle grips on there yoke as a alternative to the slip on grips If you have please post pictures and tips It would go on our new Ercoupe

I've just started my cross country training and I'm using an 8" Android tablet with Garmin Pilot. I've just had it resting on my lap for the last few flights, but I think I'd prefer to have it mounted on the yoke. I was thinking of buying this but I wanted to see if anyone here has any...
