Was the 12 ton pipe bender enough, or did you use the 16 ton?

Did you do this while it was on the aircraft? Is there enough room for the hydraulic pipe bender?

No, using the bender from HF, you definitely have to remove it.

Also, itís difficult to make sure you get the bend just right so that itís not cocked off to one side. Unfortunately, I ended up replacing my stinger and starting over.

This is the ideal angle, obviously not an RV but one of my 'toys' -)

I've read all I can on this recommendation but do we have any videos or math or physics or other data that shows that this is the correct angle? How is it possible that all the shopping cart wheel manufacturers around the world got this wrong?

Found this article which mentions some of the factors that can contribute to shimmy.

https://glasair-owners.com/glastar-s...-wheel-shimmy/

From what I understand in the article, even though we have a negative castor we don't always have shimmy because the "trail" is large enough.
