fill station question

hi guys,
been using a top feed 20 lb. CO2 tank, tethered for bench shooting at home.
would this setup work for a portable tank?

(i know i'll have to rig up a rack or something to hold my tank upside down to fill)
thanks,as always.

Are you talking about using the 20 oz. tanks as tethered portable tanks, or are you going to use those to bulk fill a gun? You can use a set up like that to fill the 20 oz. tanks.

yep, planning to use those 20 0z. tanks, tethered.
something to take away from the house. camping and such.

any idea how many shots out of those 20 oz. tanks,
using it for a qb78 and a xs60c set up for high shot count not power?
a weekend of shooting while camping, basically. just goofing around.   

also thinking about using them at work (heating & cooling service) to blow out furnace burners and A/C drain lines in attics and rooftops instead of hauling the 20 lb up there.
that's what i use the big tank for, now.
i'm getting older and that big tank isn't getting any lighter, if you know what i mean!!!!!   

thanks for the advice.
