I am going out on a limb here but I've found that a person with your skills (and I've read a lot of your work here over the years so I think you're likely "one of Us") finds few insurmountable challenges when working with precision machinery.
It's a matter of having the proper tools - small screwdrivers, brass/ wood/ plastic mallets for procedures requiring light percussion, various punches for various types of pin removal, and dental probes of varying shapes for seal removal, spring tension, etc.
You'll need some varying grades of grease - many of which are used in bicycle repair stations (where I learned most of this precision setup work). Many threaded connections require light lubrication to prevent loosening over time. And you have to know that grease and lubricants are not always your friend - they have their place and application - not to be used on all surfaces and connection points wholesale. Lubricant's can both lubricate and attract/ trap debris - which can ultimately be a very bad thing.
I'm sure I'll build a proper bench as time goes on but necessity is the mother of invention and I've come up with some clever work-arounds for difficult process.
That rifle sounds like a real super-cool challenge.
I got away from air rifles after I wore-out my first Daisy pump-action BB/pellet gun.
I had no idea that air rifles came in larger calibers. Lost of advantages over powder weapons given the shortageq of factory ammunition or reloading supplies caused by panic.
And I just finished sending an email to tech support at Hornady manufacturing.
Hopefully I'll have some advice soon and can continue the training session.
