BW Classic Valve Reg Cap

[El Gringo]

Awesome. I not only want, but need

[Jono]

What is thread type and size of classic valve regulator I need to know in order to have a cap made by machinest to replace regulator ? Unless some one has caps for sell already?

[superman]

I plan to cut more. Got power to my mill last week.

Hang on a minute, if you're going to drop the A.I.R. from a classic valve mag and use a back cap, couldn't the back cap serve as a volumizer?

Hmm, the more I think about it, I suppose the on/off closing during the firing sequence would prevent you from using the back cap to effectively increase the dump chamber volume. Too bad. I suppose at best you could use a high volume back cap as a kind of buffer between the HPR and the on/off to smooth out any recharge hiccups, but that's probably not enough of a benefit to be worth the work.

I'm still a little fascinated by the idea of somehow using the space freed up by dropping the A.I.R. as a sort of screw-on Magic Box. You'd have to drill a new air passage to link the void space in the back cap with the dump chamber, but at the same time somehow isolate that path from the incoming air supply (otherwise you'd be defeating the on/off). Damn, that would be complicated.

The one thing I wish could be changed about Automag design is the dump chamber volume, since it sets such a high floor for operating pressure.

I lately have been experimenting alot with dump chamber volume. I started with a magic box valve than I remove magic box parts which is just a tiny expansion tube chamber.i replace with a 90° 1/8npt elbow fitting followed by a a threaded stainless steel refillable 12 gram co2 cartridge which fits 1/8npt threads perfect. I also have a 16 gram threaded cartridge that fits nicely. A threaded disposable co2 cartridge can be found in almost any size I have a 45 gram cartridge that fits infact. My goal was highest velocity not air efficiency I was running with a deleted regulator in order to allow much higher psi in valve as much as 1800psi I noticed a much higher velocity with the enlarged dump chamber I plan to try larger co2 cartridge in future. Currently I'm running co2 instead of hpa. I wrapped nichrome wire around the expansion chamber connected to a 11.1v lith ion high discharge battery in grip with a pressure switch to activate. This allows me to rapidly heat up the dump chamber co2 which leads to a controlled co2 expansion in order to raise psi as high as 3000 before burst disk releases for safety sake . It goes from ,800 psi to 2000 very quickly allowing for high powered shots similar to 1800 psi hpa shots I've tested with previous .
marker is a classic automag converted to magfed with a 75 gram co2 cartridge I refill with larger external bottle. The 75g cartridge runs into a on off nob first then to the fill port then another on off than into a 3 stage co2 expansion chamber this is the black cylinder in pictures then down into valve. then from magic box port hole first a 3k burst disk then psi guage and finally the 12g co2 cartridge I have wrapped in heating element wire. even with just a 5 inch barrel it shoots .6875 steel ball bearings well over 100 joules.
Just for fun in the spirit of fn 303 less lethal launcher.
I need regulator cap made with 1/8npt hole in back so I can feed air in through rear for other projects I have.

How much they going to sell for?

[Wishbone]

Very nice work

Any update? I purchased a mini mag from here and it looks like the back half of the reg is some off brand so I'm interested.

[superman]

Unfortunately no, I have been studying in my free time to take a test for my day job that I need to pass. So this and pretty much all custom work has taken a back seat. Good news is the test is tomorrow so we shall see how that goes.

Wanting to do the same regulator delete mod with the sidewinder on the vasa. Where can I get the end cap?

[superman]

I have a few made and will have them listed to my website here shortly. I have been mulling over the price, but should have them listed here shortly.

[Meglomachinist]

Let me know when those post I got a build would be perfect with one.

Added to the website.

I also added valve body milling if people are interested.

[Myrkul]

Oh man, website lists sold out? I can think of a project that the valve cap would be perfect for....

[Txaggie08]

I have been working on this awhile and yes this is the other part that is planned to go with the rail i made.
Thread milling kicked my butt but i figured it out. I ended up scraping the first one due to a funky tool path but this one came out great.

Did you build that rail? Sorry still wading back in on things.

[superman]

Yes, i did machine the rail as well. I need to pick up a tumbler before i list those though. the edges need to be rounded over since it is still sharp.

[superman]

Here is the video I did on the mag rail.

[Meglomachinist]

Sweet looks like I got the last one. Will be sending the valve off to you at some point to do the mod. Gonna be a nice touch to the micromag I'm working on.

[superman]

Thank you! I’ll have it out today.

[Meglomachinist]

Cap arrived today so mocking things up. Need to machine down the micro thinking everything in the hatched lines...goes away.

[FredMnkyDad10]

Dude cut up any other mag body or rail. Or at least one that is already jacked up. I may have such a body.

[Meglomachinist]

Well this micro is far from a showpiece, if you saw it up close you'd see what I'm talking about. picked it up about a year back with a huge parts lot for next to nothing. Still need to strip it and the plan is polish out the body and ano all the small parts. I also have a few classic rails etc that I could mod but I think this combo will pop. Don't worry it's not gonna be a hack job.

[ConradCustoms]

What's the phrase from Doom? Rip and Tear until it is done!

[Meglomachinist]

Hahahahaha...yeah if it was pristine I wouldn't be chopping it but this one is far from it so I don't feel too bad making a few adjustments to make it something different. Now the scary part is firing up the 7.5 HP baldor buffer I have to polish it out ain't gonna lie that big sob kind of scares me spinning 14 inch buffs.
