PP750 power mods on Going!

[Long_Gun_Dallas]

Good stuff!    That gun must have a healthy plenum volume.  What is the barrel length leade to crown?  Seems youve got it running at peak efficiency, Travis.  Impressive!

🍿 hey, it works!

Just means I’m watchin’ this thread Travis, and thanks.

... I figured it would be in my best interest to have a professional airgun smith do the work.

You can do it!!! Deburring and polishing is not programming a CNC mill. Just go slowly with the right abrasives and have good digital calipers and use them.

Agree with Johnny it’s not Rocket science just go slow and take your time. All the information is right here you need.

Thanks for your kind words of encouragement guys, much appreciated.

Excellent results Travis. I know Brian said they were pretty rough from the factory. With all those little parts I figured it would be in my best interest to have a professional airgun smith do the work.

I don’t know who Brian is but he’s correct it’s a bit rough but really not to bad! A little work and the diamond really shines! It’s a fantastic gun for the money

Just like the PP700- well worth the "cost of admission".  I'll be very interested in free-flighting the hammer.

I've not even touched mine except to charge with air, load pellets, and pull the trigger.  I'm not interested in power so much as tuning for efficiency, but we have about eleventeen projects ahead of tuning.  Heck, my Leshiy still has a regulator and Wika waiting to be installed...

Chris (bear air),

Have a backup plan if a mod / maintenance / exploration goes wonky... another gun to shoot, resources to figure it out (here).

Most of the guys on here that tinker or tinker at a high level have all gotten in 'over their head' and had to have a Tall Glass of Calm Down. They got over it and got better.

I'm in charge and I won't let the metal beat me, example: the wonky angled trigger spring in the Artemis PP700SA. I fought to re-assemble it, maintaining the angle and seats,using grease to keep it in place and was definitely uncertain that it was correct. Forget that noise. I cleaned it thoroughly and Super Glued the spring to the trigger part. Done, and no harm done, and I KNOW it's assembled correctly.

Hi,

I don't even know what free-flighting means?

I am curious.

[JohnnyPDX]

I found this explanation of free flighting and hammer bounce at AGN. NOT promoting their site but interested in sharing info.

  Hey Johnny, reminds me of an old Super Glue saying (for everything, not just involving airguns), "Unsure what to do? Just use Super Glue!"

 Need to figure out how to mount a gauge for the  regulator output. This is going to take some 🤔

Funny. I got it done AND I am confident about working on the trigger without worrying about a cock-eyed spring. When re-assembled it's difficult to tell if that spring is seated properly. The gun will function with it slightly out of place. Not close enough!

 If i make part #66 thicker I can put a gauge there and increase plenum size!

Part 66 is gonna change things!

...get your kix, on Route (part) 66...

...get your kix, on Route (part) 66...

Yeah!!!!

We need coffee and some ENTHUSIASM. Lot of corpses around here, what's up.

Looking great Travis!

It is amazing how responsive this pistol is to tuning, or how untuned it left the factory... either way it is a lot of fun.

Knowing the set point is difficult, minor adjustments make big changes. Looking forward to your gauge mod.

You to Thane! Do the barrel mod with the single TP it really changes the sound and efficency brother!

If anyone is wondering, part #66 is the black part in Travis's hands on pictures 4 and 5 in his first post 
Edit: (I initially mentioned thane instead of Travis, because I confused my 2 favorite threads of the moment) 
Sorry guys .
