Fittings seem to be NAS516-1A, a little obscure, but found on the internet at aircraft suppliers.

Just thinking about a tool to allow easy replacement of Girdraulic spindles with "drilled" spindles.
Or is there an easier way.
Not sure if 9/16 rod stock is easily obtained
maybe just drill an old spindle?

The idea is to screw it on existing spindle, and push old one out keeping all parts in line, then feed drilled on back in. This would be great for 3 outta four spindles.

But I am not sure about FF3 big end without disassembly??

Well, that`s one way of finding out if your spindles are worn out.

How do you set and drill a 1/8" hole in this FF14 spindle?
What is the proper drill bit or bits?
What is proper speed ?
What is proper feed technique?

Gun drilling is one solution. A gun drill is a self-piloting drill with a carbide tip and a hole through its length for high pressure lubrication. I would look for a machinist or gun smith who feels comfortable drilling long holes.

I once managed to drill out a snapped rear wheel adjusting screw (1/4BSF):eek: without damaging the lug thread, but I would not like to try it again
Too far, too thin.
