Asw19 rudder bolt (evil)

Since we're drifting already anyway... the next level of hell is trying to remove the rudder from a Grob Twin Astir that's been stored outside. Cursing in 6 languages, ruptured blood vessels, gallons of penetrating oil, and entreaties to various deities didn't do it. All I remember is that we eventually ended custom-manufacturing what amounts to a bearing puller. Luckily, we have the world's best machinist in the club.

I suppose you are talking about the transverse bolt through the "swivel block" in the nose? I assume it's the same as on the ASW-20... Normally, you don't have to unscrew that bolt (you might well have to cut a hole through the side of the nose to take it out). If you undo the bolt at the rear of the spring (canopy side), the gas spring can then be unscrewed from the front "swivel block". That block is tapped for the M8 plunger end, it is not integral with the plunger.


That is all fine if you have a gas spring that you can be unscrewed from front fitting, mine was stamped fixed...

Go to any medical hardware store and invest in a pair of lean long-reach
surgical pliers that can be locked into place. Even better than a pair of
bulky pliers. Have been using them for years now. Bought lots of
lottery-tickets since the rudder goes in in one go most of the time...

Gas strut for canopy: factory sells a handy compression tool. Use an allen
key to align the holes. Works even better if fuselage upside down for
access, and instrument panel removed.

Better to look at a surgical supply (or "Medical marijuana supplier") and ask for "10" hemostats", or, "long roach clips". They lock in place.

The SS safety wire is cheap, does many things and won't tend to raise a ton of questions from "official looking types wearing official looking uniforms of various colors".
