Do Crosman make the Benjamin pump up rifle now?

hardest job with the 2200 is opening the valve as they loctite'd them and you have very little to grip them at the front o ring groove
one way is to remove the o ring and wrap wire in the groove then you can grip it without chewing it up
I use the lathe and er collets to undo them
the early valves had a 3 part stem which is obsolete but the later 2100 stem fits (a 1377 later stem can be used but you have to shorten the shaft a tad)I've started refurbing the old stems by making a new carbon ptfe body

Wow I have to admit that you lost me pretty early on there... I certainly have no lathe, possibly it would be easier for mechanical tards like myself to just buy a new valve! Having said that I tried to picture everything you wrote and can only be envious and impressed by your skills
