Scott 2k ear extensions?

[JackC]

Hey all, just curious, I have these bolt attachments for the chains on the rudder horns, figure over the years they’ll take the wear vs the horns.

But the tailwheel ears, which seems parts are getting more scarce for, the SS chain end links are attached right to, and would be wearing on, the tailwheel ears, is there something sacrificial that can, or should, go there?

Thanks

I have never worn one out, and believe me I have tried. Eight landings today, and that was a slow day. But I have had those little toilet clips fail often enough that I use heavy steel wire for the attach. My heavy steel has never failed.

But you can buy bolts - AN bolts - with an ear on top, for the toilet clip to fit in, and while your angle is pretty good, they make angles a lot better on some other aircraft types.

There are also these neat mountain climbing things that are stronger than all get-out, and have a screw on barrel that makes them a continuous oval. Dirt common, but I do not know their name. Oops - carabiner!

So probably not needed?

Was there supposed to be a picture in your first post, Jack?

 

[Bob Turner]

Jack - I used to worry about stuff like that. Our Cub rudder arms are cast aluminum and they do wear, but these are steel, and unless you plan on doing more landings than me (almost daily for 64 years) you will not elongate those holes beyond usefulness. If you do, then just add some bronzeweld. Or better yet, get an API tailwheel.

The one to watch is the AN-3 that holds the cable to the rudder.. Even with proper lubrication, a thousand hours will give you a bolt that looks more like an oval than round.

Bart - his photo showed up last night and today as well on the iPad.

Is there a reason NOT to use the AN42 bolts?

 

[Bob Turner]

If your angle is ok, you don't need them. If you don't need them you save $ and weight.

In that case I’ll leave it alone

Thanks guys
