    Sorry it took so long. After I finished the pic I forgot all about needing to get Frontpage on this machine as well. Anyway…….

    Nothing crazy here but I think there are a few decent ideas. This regulator would be inside the tank but still be adjustable without having to remove it.

    The regulator would use two tubes instead of one. This would allow the spring chamber to be vented to the outside air and also allow you to change the PSI setting by screwing in the inner tube without having to remove the regulator. You would also be able to unscrew the inner tube and remove it along with the regulator piston and springs without losing pressure in the outer tank. The high pressure valve and outer tube would remain in the tank.

    A: This is where the inner tube and its end cap slide inside the outer tube. There would need to be a gap between the tubes or the inner tube would need to be scored to allow air to pass between them. Im concerned that the two opposing pressure chambers will force the tube walls together and lock it in place. To overcome this the two mating surfaces could be polished or a small gap between them might be necessary.

    B: This is the vent to the outside air.

    C: These are the mating surfaces connecting the machined parts and the tubes. Normally these would be threaded but I was wondering if sweating or soldering the joints would be an alternative. I know they do this in high pressure AC lines. You would not need to remove them once joined so I think this would make the machining process allot easier and would cut out all the Orings needed if it were threaded.

    D: I was thinking about threading the end of the piston so that you could screw a long rod into it for removal. Otherwise the piston would be hard to get out of the regulator for service.

    Sorry Mike, this wasnt done to scale, again, but looking at your regulator I dont see why they wouldnt fit in the available space. I would love your feedback or thoughts on this one.

    A couple negatives to this design.

    It couldnt be modified to work with existing valves. I think I would rather have this mated to a low back-pressure valve anyway so that I could run a smaller spring and hammer on the other end.

    Using two tubes will reduce the regulated chamber volume. I dont think it will be much though especially if the two tubes can share the pressure load and not lock up due to the two opposing pressure chambers.

    Im beat, thats all I can think of atm. Im sure I mussed something up but I know you guys will point it out for me ) Thanks in advance.

    Wow,

    I envy you guys who can draw this stuff. I bet you could design a wicked SEX TOY if you had a mind too 😳

    Looks nice Shadoh. Unfortunatly I dont fully understand how regs work so other than saying it looks pretty I cant add anything useful to the thread…

    I think the chambers regulate the larger pressure to a consistent lower usable pressure, sort of the regulators for using air tools and air sprayers…

    Air tools like 100psi and the sprayers like 25psi but they al hook up to the same compressor which supplies 150psi all the time… A water trap is typically combined with a t handle regulator, the out pressure at the at the connector is controlled by the t-handle, screw it down for more pressure, unscrew for less.

    After each adjustment you have to give the system a quick squirt so the diaphragm can settle and the proper pressure is attained… Kind of like when you adjust the power wheel on the talon, one shot to settle the setting.

    You should see FinMike’s shot string with the regulator… It is on the TOG…

    Very impressive idea for everyone involved!

    McMike here is FinMike there. It has been posted here for awhile. http://talonairgun.com/forum/viewtopic.php?p=7179&highlight=#7179

    We love these guys……love how they make the rest of us look like hairy apes on our computers

    😀 OK that makes sense, I was wondering why it wasn’t here, my net connection sucks and the photos don’t load from time to time…

    These guys are on another level here! 😯

    Shadoh, you need to draw it to scale using a real world spring. IIRC Mike did convey that advice. Keep sketching, next is building it.
    Walter…

    Which spring would that be Walter? Am I missing seeing a spring in that picture?

    I think the pink stuff is the spring thing… 😕

    Pink stuff are stacked washers… which act as a spring… i think.

    Yeah, they are springs, McMike showed me those long ago and uses them in his regulator. Mike has shown that they do make them in the correct sizes for this type of project.

    McMike posted his 100 shot strings with his regulator on TOG. His design looks pretty sweet.

    You must of missed it. He posted it here also 😀 Look a few post above
