Others RAW Hm1000x externally adjustable regulator

[Woogie_man]

Hey guys,

Say with winter starting to move in up here in the north, I have been thinking of more modding and other things. Along with other hobbies that I have of course. That got me to thinking about trying to push the HM1000X a little more and try and get some more of the boat tail slugs to work better than what they currently do. I am able to shoot my custom 34 grain slugs at around 920ish fps, and would like to shoot closer to the 40 grain if possible. Now this will require me to push the regulator harder and get things moving quicker. This will require the adjustment of the regulator, and with an inline regulator it can make things a pain when trying to set up and tune things.

So this got me to wondering about how hard would it be get a regulator that is adjustable externally? Would make adjustments SO much easier and quicker than it currently is. I am not sure how something like that would be accomplished, but I know we have quite the crew around here that may know something.

So what do you guys think, or know?

I did remove the OEM reg I went with a Huben Power Dream Universal with the 20cc plenum. Required a m18 male to male adapter.

Adjustable up only. Degas to go down.

It is long and ugly and needed extending to clear the stock. Probably works better with the tactical stock.

That is indeed......interesting.

I have removed my regulator and am going to use my external reg to find a good set point. But something more permanent would be nice

My brother would call it
"Another stupid plan"
I will probably redo the whole thing with a Huben Power Cricket Max-ATH if it will fit.
The plenum on that regulator is pretty fat.

 

[Woogie_man]

I'm with you man....probably not something I should be thinking about, let alone trying to figure out how to do it.

I just dismantled my RAW and didn't see the regulator stack! Well stupid me I thought I didn't install one....only to dismantle the steel part and realize that it was a smaller regulator! Thinking a HUMA but there are no markings or anything on it.....so not sure.

 

[SpindleB]

On the left Huma
On the right RAW

 

[Woogie_man]

What does the under side of thr huma look like? Is there a small exit orfice?

Wonder how much I could push this thing, and what could be modified to make it go more?

 

[SpindleB]

The air path is through the regulator.
I blew air through both and the Huma passes a lot less air. The hole is much smaller than the RAW regulator.

 

[Woogie_man]

Ok this must be a huma. Wonder what would happen if you were to open the exit orifice?

 

[pan60]

wont it just fill the plenum faster?

 

[Woogie_man]

That is what I was thinking, and when using the rifle in matches the faster I can shoot the better. And with a faster recharge rate will help stabilize the spread.

Currently I have the Huma reg disassembled and just a blank. This will allow me to use the external regulator and get things dialed in MUCH quicker. Then I will be able to manually set the internal reg and get things going. I do have a few hundred ACE slugs coming to play with...... and if those work great I am planning on buying the die set.

 

[SpindleB]

Ok this must be a huma. Wonder what would happen if you were to open the exit orifice?

You could, not sure I would. It might affect the operation of the regulator.

 

[Woogie_man]

May see if I can't fit the huma parts into the stock part first. But things are set up for testing heavier slugs....

 

[Woogie_man]

Went to go and test things out......only to find that you need a regulator in the rifle. Without it the air just bleeds out the exhaust hole in the regulator body part. So I have some parts coming that I am going to attempt to make a delete part. I did get the rifle to hold air.....but after a shot the air bleeds out..... and the air only stops if the rifle is cocked.

I am hoping that this will allow me to use the external regulator with an external tank.

 

[SpindleB]

Mine works fine with no internal regulator.
Must be different models

 

[Woogie_man]

Yeah mine doesn't have the blanking plug in it.

Currently have an extended plenum on it and then the regulator attached to that. But the threads are different from the regulator to the bottle.

 

[SpindleB]

Same here
Gun -> plenum -> adapter-> regulator

 

[Woogie_man]

Yeah mine doesn't have the adapter part. So that's what I am going to make

 

[Woogie_man]

Parts should be here tomorrow..... so that will give me some time to play with the parts to get a solid seal. HOPE this will work so I can get a tune for some of these "fun slugs"

 

[Woogie_man]

Parts showed up and they look like they will fit. Going to modify the threads in one to make sure I get full engagement on the foster fitting. Will be able to toss in the lathe tomorrow and get the threads cut and be able to pressure test tomorrow.
