PP700 adventure started(Artemis PP700s-a)

[BSJ]

I started combing this thread from the beginning, I made it to Pg 19...  I'll go through the rest if I have to, but...

I have a Gen2 (black grip, non-round barrel shroud) .22 PP700 I haven't torn into yet.  I have a few questions before I do:

-  I'd like to install a HuMa reg- what pressure should I request if I'm looking for around 9-10 fpe?  12 fpe?  I don't want to go above 12 fpe...  This is for close range pesting, and I DO have to worry about over-penetration, with regard to damage to what's behind the target.  i.e. roof shingles, wood around the roof of a house/building.  Max range around 20 yards.

-  I snagged the list of o-rings from the first couple of pages:

1.5mm X 4mm Buna-N 70
1.5mm X 5mm Buna-N 70
1.5mm X 8mm Buna-N 70
1.5mm X 9mm Buna-N 70
1.5mm X 11mm Buna-N 70
1.5mm X 12.5mm Buna-N 70
1.5mm X 13mm Buna-N 70
3mm X 21mm Buna-N 70

Is this list/sizes still accurate? 
Do we know what size o-ring will be good to use for the "3mm x 21mm" size?  I remember people finding a hard time finding that particular size. 
Which one of the above sizes is the barrel breech (or chamber) o-ring? 
Speaking of o-rings, how is the quality of o-rings from the o-ring store online?  Has anyone found a source for higher quality o-rings? 

-  Has anyone found a better way to hold the barrel than drilling/tapping a 3mm hole for a grub screw?  I'd rather not do that, if at all possible.

I think that about covers my questions/concerns...  TIA y'all!!

 

I set mine at 105bar.

Many thanks for the reg pressures, and all the help!

Here is the size list I made from the schematics I got from another source, and I attached the pdf:
PART NO.    SIZEmm     QUANTITY
6                 12x1.5        1*
11                14x1.5        1*
13                16x1.5        2*
24                7x1.5         1*
25                15.5x1.5     2*
31                8x1.5         2*
33               11x1.5        2*
35               27x3.1        2
...I will note that I was unable to find a 27x3.1 o-ring, but I did find a 27x3.  I haven't tried to install it to know if it will work.

FYI, the 3.1x27mm isn't called out correctly.  In the spares that come with the gun, there is a 3.1x21.  Its outside diameter is ~27mm but metric O-rings are described by the inside diameter. 

With that said, it doesn't seem to be a standard size based on Marco Rubber's chart:
http://www.marcorubber.com/userAssets/file/size-charts/CommonMetricSizes.pdf

A 3x21mm will surely work.  I suspect a -211 (3.5x27.3mm) in 50 durometer would probably work fine as well.

So is THIS the correct list of o-rings that I need?  Also, has anyone confirmed whether the 3x21mm worked (what duro?), or the 3.5x27.3mm in 50 duro worked?  I'm just wanting to make sure before I go to the o-ring store and make my purchase...  Oh, and what size is the green o-ring:

[YEMX]

This will probably seem silly, but has anyone thought about or is working on a new hammer for the PP700?  Not really to get a heavier hit, but I guess more for durability?  I dunno, the factory hammer just looks so... cheap?  The rest of the gun looks amazing, the machining and even finish and such.  But that hammer...  *shudders*  Anyhoo... just thought I'd ask.

[Wayne52]

I've never heard of anyone having problems with the hammer on them I just took a good look at mine and the chrome plating seems to be fine where it hits

I finally completed my Airmax MkII carbine build . She now has a 6 inch accessory rail and now I have a place to mount my IR light for night time ratting. Im dubbing it the "Budget Leshy".

[screwwork]

Looking good Lee, budget leshy lol that is a great name for it.

[YEMX]

"Budget Leshy"?  More like a PP700 "Lee-shy"      That looks amazing!

Is anyone here in the States making new fill probes for these pistols yet?  Just wondering.

[Wayne52]

None that I'm aware of Tom

[sawtoothscream]

With Travis picking up spa maybe he will turn some out,  I know I will lose it someday lol

[Wayne52]

I honestly think that the fill probe that came with my PP700SA was too soft of brass because where the whip hooks up to it got chewed up in a short period of time, the brass probe that came with my M16 is holding up perfectly so far and I've used it extensively, I'm sure it's going to last for a long time by the looks of it.  The PP700SA I could see that I was going to have to do something about the probe soon because it was almost impossible to hook the whip up to it much more because I'd already dressed it up once on my drill press to get it to work.  I then ordered that one made in England and haven't had a problem since but on the other hand other people had gotten bad probes from them that needed to be dressed up to begin with in order to make them work.

Hello, Im new here, a great forum, Ive read this thread until page 34 now, will keep reading as I have time.... but in the meantime I would just try to ask 2 things about my PP700W 5.5mm...

By the way, what a great little pistol 

I removed the airtube, was just fixing the leak where the white nylon sits(its all ok now)...
And while I hade those parts on my table, I just thought I would check how the regulator is build up... så I completely took the regulator apart, The I realized when I was going to put the regulator together, how long in should the "intake  valve needle part nr 32" be screwed in? I remember it was not  completly turned in against the white plastic"intake valve washer nr 31", it was some play, so when i reasambled the regultaor together, I gave some play...... Is there a way to know if that little screw/valve needle is to much in or out? or should it be tighten as far as i goes? There is some threads left on that little screw, so I can take if further in, but Im not sure its right?

The pistol shoots ok now, so its working, but I hate to keep thinking and not knowing if that little threaded screw is the right distance down into the "valve piston nr26",,, this keeps me sleeping bad
I think the play between the little screw and the white platsic washer was around 1mm or so when I put the regulator together... And I could have tightened it more of course, but was sure that "play" needed to there.

Sorry for my bad english

Your English is better than most who post, but I am afraid that I am not qualified to answer your question.

Someone here will know, and will respond.

Enjoy your pistol.  I love the two that I own.

I know Huma sells stainless steel fill probes.

The little white disc has a bevel on one side of the hole in the center. You should be able to tighten that little screw down as long as the bevel is facing the head of the screw. I accidentally got it flipped on mine, and put it back together, only to find out the gun wouldn't shoot, lol. I had to SLOWLY unscrew the air cylinder to get it to leak the air out, before I could fix my mistake.

[rumbleUU]

ok, I will look at it later, I wasnt paying attention for the bevel to be there..., But I will check it again 


what the heck, Im opening it now,,,, will post later what I find out..

[rumbleUU]

OK, now I have removed the regulator, there was like one more turn on the little screw to make, so I did it, put some tiny amount of blue loctite to prevent it from moving. Put all together.... washers in same stock way.
did tighten the valve nut about the same as it was..... put all together with new silicone lube om orings...

Air in the tube,seems to keep tight, did dry fire, and it seems its waisting lot of air? (if i dry fire 3 times it goes down 10 bar) could it be the difference bewteen one more turn on the little screw? well, dont have time more today to test how the speed is now...

I will losen the hammer spring tension until it drops speed, and then check the speed,,, berfore I hade it exact on 9 joules... I want that again....

Well I think my english is so so, the most important part is you ALL understand me

   Looks like pretty good English to me Sebastian!  And I am keeping my eyes open to see how you get along with your new pistol.  I just acquired one too and am always eager to see how people overcome difficulties.

will post all my work info right here

   I was so excited that I braved the heat after my radiation to try this thing out. 

I was really bummed when it shot 16cm left of the bull at 5m.  But I went inside and pulled the barrel and put it back on and snugged things up and this was my result.....10 shots with Quiang Yuen training pellets at 10m rested with the iron sights.  The circle is 1”. Or about 25.5mm or so.  I shot ten getting sighted in and ten on target so that’s 20 shots from 190bar to 140bar.   Not too bad out of the box.
