Millennium Pumper Production - *The Beginning* - And The Lousy End

[HillGSA]

Dwyer series SGC2 may be the same gauge you are referring to:

I'm using this gauge and only have two examples.  They are not great.  There must be something  better.

We're all ears...

I didn't like the gauges from Dwyer.  I put one on a disco double I build, and the plastic face plate came off.  I never even got to air it up!

I'm listening too.  I sure would like to find a 1" gauge that was rated at least 5% mid-scale. Oh, maybe they are just unmarked for McMaster but I always feel more confident when the manufacturer has enough pride to put their name on their product.

Ok, I just got 953 fps out of a King @ 2000 psi and 780 fps out of a 37gr Spitzer @ 1800 psi.
The Disco gauge is reading 400 psi low
I will most likely go to a different gauge vs the factory gauge.

That's with the Disco poppet...the Mrod poppets should be here tomorrow...today I am sleeving all of the valves with a brass bushing so I'm ready to go tomorrow.

Its starting to get good guys!!!

Bring on the valves, Mike.  I feel a power trip coming on.

Do they have any of them Gauges in BAR ?...I want to get rid of the stinking psi Gauge in my Marauder pistol.

[CarsonRatSniper]

If I find a great, high quality gauge I will share the source with *everybody*!

The Crosman gauges are $17! I don't care if the gauges are $25 or more each...I just want the best gauge I can source for these rifles.
I need 3000 psi gauges since the Millenniums can be safely filled to that pressure when tethering...it may not need to be filled to more than 1800 psi or 2000 psi...but I want to be able to really crank her up with a .30 cal barrel and a 52 grain EPP/UG slug when I want to get serious.

I'm on the hunt for a good gauge...

How much are digital gauges these days?

[PakProtector]

It would be best to figure a way to mount a 1.5" gages from McMaster. Significantly better accuracy and precision.  http://www.mcmaster.com/#atmospheric-pressure-gauges/=voecrd

Click on the McMaster-Carr link that Pak provided, click on the Compact Stainless Steel Gauges (third row down, far left), then you will see the gauges listed.  Click on the 0-700 to 0-4000 listing and it opens to the 0-3000 and 0-4000 range gauges.  They don't look too bad with a +_2% accuracy at mid range.  Inexpensive too!

Those are ungraded gauges. I would think at least a grade B gauge should be used in this application.

If you plan on filling to 3000# occasionally, A 4000# gauge would be better to get the readings closer to mid scale where they are more accurate.  Regards, Tom

[Hanabata808]

Might check with some dive shops or other places like medical/industrial where accuracy is critical.
I was looking at some glycerin filled gauges; by reading about them they seemed more accurate. I found some of these (not sure if they'd be a perfect match for this application, but might help point you in that direction).

WIKA gauge

Grainger.com

Could also try reaching out to Joe B at airtanksforsale since he uses glycerin filled gauges in his tanks as well. He might be able to point you to his source for those gauges.

Ditto what Tom said about 4000 psi gauge if there is intent to fill to 3000.

[CarsonRatSniper]

Thank you everybody!
I measured the Blaster stock width @ the gauge port - a 1.5" will fit but the stock will be too thin on the sides to make me comfortable with it.
It has to be a 1" gauge - and I cometely agree it should have a 1% margin of error.

I'll contact Joe B - since he deals with all sorts of gauges he might know right away where to find what I'm looking for...

Mike:
I've been looking for such a gauge for a long time. Someone needs to take the initiative and have Ashcroft, or some other US gauge manufacturer design such  a gauge to our specs. You would sell a ton of them!

John

Or, just mount the gauge on the side... Like a USFT, or a Challenger.  On the next run.  You have a fill nipple on one side, just put a gauge on the other.  That way you can use a 1.5" Ashcroft gauge...  Or perhaps mod the design a hair and like on the USFT, have the gauge and nipple next to each other.

[dyotat100]

There's a reason they are $10-$20. Good gauges cost a lot.
Even the 2.5" ones Joe B sells can be 100-200 psi off. I have seen the 1" gauges off by as much as 500 psi.

I have bought a few 2.5" Wiki gauges from McMaster Carr and none of them are perfect. They are basically what Joe sells. Last one blew the plug and leaked all over the concrete at the range. That the second time that has happened.

I have since went to the digital gauge that's around $200 and have 2 fill setups with them.

But I also have a digital gauge that is +-.25% to check reg settings and other gauges. It is around $400 and with cert paper it is almost a $1000.

Here's a pic of the action with a factory top end

This is one of the straight cut stocks - the fore arm pump handles will be cut at a slight angle about 3" farther back than this one.



The entire shop is dedicated to the Millennium builds beginning next week and I have all week off to work on them with Jim...we should have pics of a completed rifle by Valentines Day.

Oh!  Valentines day with your new honeys

Nice work mike.  I been enjoying watching your progress and marveling at the speed this project progressing.

  As to gauges, you might want to check out the gauges Ricky is using on his twin cylinder build.   I'm actually liking this one.   0-5K with a 210* sweep.

Very nice...so what's going on with the valves?  I got a 3kpsi tube that is feeling neglected.
