you may be right, but if theres even a chance, i would like to try it...
in theory [if the pump has a check valve like you say] all i would need is a lump of ally or brass with 2 holes drilled next to each other [probe size holes] so that i can fit the pump probe in one, the bottle probe in the other... and a smaller hole at 90 degrees joining the 2 holes [centrally ie between the o-rings of the probes] and then block off the holes entrance........ should be quite easy to make without any fancy tools maybe ?

The Theoben bottle has a removable neck,the bit that you screw onto to fill, the neck has a ball bearing in to stop the air when the bottle is off the gun, so i thought it would do the same job as when filling ,it would only need a connector on both ends, the normal one that the rapids use an then another connector to you bottle.

Take ten minutes , going to take Two weeks to fill,,, This comment is just playing.

Daft idea.
Given the heat the pump would generate, it would likely take a fair few hours having to stop and wait for it to cool. You'll end up knacking the pump, so don't bother.
If you want to fill it yourself, buy a compressor

I have a Hills pump with drypack, and often pump my 3litre cylinder from 160bar to 210bar,
best done outside in a breeze
... Its not difficult you bunch of wimps!!
. . . Please INDICATE when overtaking cyclists !!
some of you guys are [i think] skimming over the point of a few pumps / day ..... bit of excersize , not enough to build up much heat , done indoors in a dry atmoshpere [plus the pump has a dry pack]
im not saying its going to be easy, but i was thinking little and ofter kinda thing... so long as [for example] i can get my bottle from 150 bar back to 200+ bar in a week, then thats all i would need

Moisture getting into the bottle is my issue with this, forget how long pumping would take and whether it is done all at once or a wee bit at a time.
Surely if you decide to do this you should have your bottle hydrostat tested at 2 year (like divers do?) intervals as the moisture in the bottle may corrode and weaken the bottle. I don't fancy your chances of saving much cash what with paying for hydrostats, possibly/probably blasting the corrosion and finally buying a new dive bottle at more frequent intervals.........of course it depends on how often you need to fill the bottle based on how much shooting you do.
Cheaper all round to just buy a springer so you can save some air and make it last longer therefore decreasing the frequency with which the bottle requires refilling.
Hth
I like tinkering and banging
because if i go for a days shooting, i might get through 4 fills .... take the bottle for plinking, top it up during the week when not shooting

Just move closer to the dive centre.

Ouch!
