PP700 adventure started(Artemis PP700s-a)

[ecolwell]

Not sure if it was this thread or not but I bought a stainless one from England I think, can't remember exactly where I bought it, it's been a while.



I got mine from TRRob https://www.trrobb.com/SMK_Artemis_Pre-Charge_target_pistol_Stainless_Steel_Filler_Probe/p1449438_17414808.aspx

I received my TR Robb fill probe today and as others have mentioned, it is too big to fit into any female foster's that I have (5 or 6).  I sent him an email a few minutes ago, so we will see how this goes.  The one he sent for my PP700 measures .315" and the others that I have (Edgun, Crosman, JoeB, etc) measure about .310"...

I just measured mine and it's about .312 but it does work good with my pumps and tank fill adapter.  I have had it for about a year now.

It is a quality looking piece.  The end that plugs into my PP700 is a good fit.  Just the Foster side is "fat".  Equally concerning is the fact that there are others here that have reported the same issue.

I ordered 2 SS probes from TRRobb last summer.  They were just slightly too large to fit into the female foster fitting but easily fixed by slight turning of the collar on the probe.  Once that was done they fit in place, retain, and fill great.  Certainly should not have to do this and it should have been corrected by now (assuming these mentioned are newly purchased) but there aren't any other options beyond the stock brass as far as I know and my stock brass ones were denting pretty badly whereas the SS ones are still perfectly smooth.  I am glad I had access to the SS ones.

That reg looks like it should do the trick a bit better for sure!  You could also put an o-ring inside the piece that the white disc sits in.  There is one in the kit that fits perfectly around the edge of it around the bottom of the threads.  I gained a lot of efficiency cranking my reg up higher than need.  You want a good snappy report.  It will almost sound quieter than it should, which means the valve is closing before the pellet leaves the barrel, and it uses much less air.  I say try at 115-125 bar, and see what happens My new version is hanging out in customs right now

I've just ordered my Huma reg. I presume that the 'o' ring replaces the white disk and isn't fitted as well?. This site has cost me a fortune so far :-)

You're going to love that Huma, and the consistency it gives you!  Keep in mind, I did mine a bit differently than others, and removed ALL factory regulator parts.  I had to make a plug to go where the adjustment cup is to get it to seal.  I believe the easiest way of doing it is to just crank down the factory regulator adjustment, and install the Huma.  I think you can remove the white disc and screw though.  Hopefully, someone that didn't remove everything like me will chime in on this one...  That extra o-ring is must for sure if you do remove the white derlin disc though.

Thanks for the reply. I'll probably show my lack of knowledge here but.......
Having looked at the reg, I presume that air has to bleed through the original white washer. I was considering machining a delrin plug to go under the original reg adjuster screw to block it off. The top hat arrangement that you made looks like it seals the area in which it seats totally........does there no need to be some flow is air into the original  reg mounting?

Hope I've not been too confusing

Hi,

i cranked the stock reg. up and left it in. no problem and i got extrem low fps spread.

Same for me. Although, I turned all of the washer the same way first.

You mean with Huma regulator?

I may be a little unsure as to what you mean, but I'll give it a go.  The piece I made keeps the air from leaking out the back side where the adjuster screw/cup thingie is.  I made that piece out of PEEK, and re-used the little o-ring that was on the little brass piece.  The depth of that little plug I made is critical, because making it too long would,indeed, seal off all air going into the gun.  All of the air going into the gun has to make it's way past where the white derlin washer is.  I just removed that all together and opened up the hole.  As the others are saying, the easy way is to just leave everything and set the factory reg to "bypass" I think.  I did it the way I did to make it flow better and effectively increase the plenum size a little.  There is no real need to do that unless you are trying to make absolute highest power though.  The gain is minimal otherwise.  I hope that helps

Yes, you have to 'disable' the factory reg. by 'adjusting' it to a set point well above the reservoir pressure when you install the Huma.

Fresh off the mill, here is the new rail adapter. It slides over the tube and is secured with a non maring set screw and a plastic disk for extra protection.

Nice work! That rail turned out great.

Just an update:  TR Robb replied to my email the very next day and said that he is shipping another probe to me with a smaller diameter male Foster end.  I look forward to receiving the smaller one, and in the meantime will take your advise and try to turn this one down about .005".  I wonder if the female Foster's "across the pond" are slightly smaller???  Anyway, just wanted to provide an update and say that TR Robb appears to be extremely responsive to my issue.

For some reason i camt get the rail pics to pull up.

[Wayne52]

As common as a problem this seems to be with the TRRob probes it seems like they'd have addressed this issue a long time ago.  They must not sell many of them from the sounds of it

Vash,

Looks good, but will you be anodizing them?

If so, I'll take one also...

Thank you!  It works well.

I hope to get into anodizing in the future. Caswell has a nice kit I'd like to get.  I tumbel the parts with abrasive media to remove the sharp edges and blend smooth the machine marks. Then I finish the parts in an auto grade matte black powder coat. If you are interested, please send me a PM.

If you send me a PM with your email, I will send them to your inbox.
