PP700 adventure started(Artemis PP700s-a)

[KnifeMaker]

Yes!

[KnifeMaker]

Yes. Remove barrel and drill. Put barrel back in and lightly-very lightly drill a divot in the barrel. Remove barrel and tap. Replace barrel and lightly tighten set screw with a touch of removable loctite or equivalent.

... a touch of removable loctite or equivalent.

I've been really liking the Vibra-TITE VC-3 , repositionable, thick doesnt run all over,  can apply and let dry then use whenever. Good stuff.

No more chatter on this?
Lol
I’m pretty sure Santa has one for me so I’ll be late to this party.

At 94 pages, all that needs to be said has been said. Use this as your owners manual. There are plenty of pages that you should click “print” on. I know I did and there are about 20 in that stack.

Can someone please tell me what modifications I have to do if I change my pp700s-a to unregulated? I´m planning to buy one PP700s-a .22 more so that I can keep another one regulated and another one unregulated.

[Rallyshark]

Long story short, you'll have to make a piece to seal the gun when you remove the regulator.  It is in the replies somewhere, but I don't have time to tell you which one at the moment.  The easier way would be to crank the reg down and remove the white derlin washer I think?  Maybe someone else will chime in on the second method, as I removed my regulator guts completely.  That required making parts though.

[elguapo99]

Just unscrew the little silver screw on the regulator a couple of turns. The gun will now be unregulated as the regulator will not seal. I mistakenly did this when I reassembled mine for the first time and it chrony'd like an unregulated gun. Then it hit me that I forgot to tighten the screw. After tightening the screw, the reg works perfectly with no creep. The travel of the regulator is very small so the screw doesn't need much loosening to make it no longer seal.

The Huma regulator website has a PDF instructional with two methods how to bypass the OEM regulator.

You guys had me at "poor man's leshiy"

Me too. Just ordered one in .22 from Canada Shooting Supply. It was the only place I found the had any in stock.

Thank you for some info...

Few days ago I got my second pp700s-a. This time I bought it from Mundilar airguns from Portugal (good service!) This time power is totally different, this new one gives almost 25joules. First one 10joules.  I noticed big difference about the size of the output hole in the transfer port. Its much more bigger than my 10joule version. The first one I bought from finnish webstore and they said afterwards that it's from swedish importer where they get these guns. So my 10joule gun is made for swedish markets with swedish airgun regulations. Because here in Finland does not have any power regulations for airguns I was bit disapointed....

So now when I noticed the power difference between these two I'm more than satisfied with the power of my new 25joule version and I first thought this time theres no really need to modificate... But my second thought says that now when I have two .22 PP's I think I must to do modifications much as possible...

Sounds like a great plan, Tommi- keep us posted on what you end up with!

This is such a great little PCP- tune mild or wild, it doesn't matter because these pistols deliver!

How do we know its safe to make this little pistol unregulated? has there been some calculations on how the valve can take twice the pressure ? just asking...  I did ask once before a time ago if its safe to make it unregulated, but now thinking of it, its twice the pressure on the valve...

[nervoustrigger]

Only the manufacturer would be in a position to answer your question directly and definitively but suffice it to say it would be a bad design if can’t safely handle the maximum fill pressure.  The designer has to know that a regulator can fail and pass full pressure to the valve, so it either has to be capable of handling it as a long-term condition, or there has to be a pressure relief (burst disk) to dump the reservoir in the event of such a failure.  So as a practical matter, the general public is counting on that being true for each and every make and model of regulated PCP that has even been made.  I don’t mean to suggest that questioning it is a faux pas, just that there is an implicit assumption that any regulated PCP is safe in the event of a regulator failure.

[rumbleUU]

I agree, it should be and most sure is designed to take full pressure at the valve (220bar), and probably with some safety margin to go with that also...

It should just be interesting make some calculation on the threads holding the valve in the back if the pistol...


Is there ANY gains(power wise and/or efficiency wise) in longer barrel in this little pistol, has anyone made a quick guess how big the plenum is?

[Rallyshark]

Jason pretty much said what I was gonna say.  You'd expect that the valve can handle the pressure.  I have shot it unregulated and didn't have any issues, but I didn't leave it that way long term. 

There is most certainly power/efficiency to be gained from a longer barrel!   That is, if you aren't going for a super low power tune, of course.

I made a long tube long barrel one in .177 for my brother in law. He wanted a simple high shot count PCP. I went with a 12” tube and a 14” barrel. Built a round functioning shroud for it. The gun was horribly unbalanced with the flimsy little stock but he didn’t mind. Had it tuned for 800fps with 10gr pellets for an impressive amount of shots. Huma was set at 130b I think. It’s been a while.
