Have not been following closely of late, but excellent work on the breech arrangements.   No immediate desire but could be interested.

That pellet tray is awesome. And since I have a 3d printer I designed something similar:


First prototype, printed at 0.2mm resolution so it looks rough...
Its a snap on fit with a magnet that is directly over the breech block port adjustment screw.

That is pretty nifty as well!

[Bizill]

How well do you expect the block will hold up to the pressure and keep the seal from allowing blowback?  I don't trust PLA, PLA+, PETG, ABS or much else to work well in place of aluminum.  But printed solid or with enough infill I may be surprised...

Nevermind, I just noticed it's a slip over tray.  Very nice idea.

You Guys never cease to amaze me . There is so much creative energy in here

Very cool idea! I like that you don't have to replace the whole part and that it quick to install. A commercial grade 3d printer would be the way to go if you were going to make lots of these. The thin walls don't lend themselves well to machining given the extra expense in building special tooling to keep the part rigid while machining the final features.

just got mine delivered,but whem pumping with hand pump no air s going in,still on yellow mark on pistol pump needle on gauge is no moving any ideas. yes the bleed nut is tight.

[bandg]

Try cocking the hammer before pumping.

thanks.it let me get some air in up to 175 but the air is leaking ut of the pistols fill hole could it be the brass probe 0rings

Make sure that there are no nicks on the o-rings then a light smear of divers silicone grease ( just a little on finger and wipe around) that way the probe will slide in without grabbing

tried  that and it worked,noticed if the whip is  bent it leaks out of the probe hole in pistol , if i straighten it a bit it pumps up fine with silicone grease applied to orings on probe.

Divers grease is a must when it comes to assembling pcp's !!!

Don did you get your Varmint yet ? I didn't think that Mike had any of them left anymore according to when I try putting one in my cart on his website.  I'm kinda thinking the the Plinkster might have the same barrel as the Varmint but I haven't got a exploded view pdf of the CR600W(Plinkster) to compare part numbers with the Varmint pdf.

I will have the .177 Varmint by the end of the week ( tomorrow 12/8 ) if the UPS driver remembers where my business address is this time . He tried to deliver my Pyramyd order to the wrong business Suite and they rejected it so before I could contact UPS it was on the way back to Pyramyd so I will not have my pistol scope for my PP700 S-a until next week sometime.

Once I have the Varmint in hand I will Post a picture of the Varmint barrell

I received a .22 from mrodair today and the barrel was loose.

So with some 90° snap ring plyers I tried to tighten it.  It wouldn't tighten.  So I took it apart.

The barrel just spins.  On my .177 PP700S-A it is threaded in and held in place by two setscrews.  The one I got from mrodair does not have any setscrews and the barrel just spins and will not tighten.

I tried pushing and pulling while turning it and nothing happens.

Any bright ideas what's going on?

Did you install the set screws, or did you get it from someone that did?

There are posts in this thread about installing the screw/s...

[MonsterMaxx]

No, I did not install setscrews, but it's possible david did when he worked on it.

However, the .177 is threaded on both ends of the barrel.  This one, seems not, I can't get it to do anything.

On these guns, they use the shroud to tension the barrel and there is nothing on the breach end to prevent the barrel from spinning. Some have used set screws which does work but on mine, I did not want to drill/tap the sides. It looks ugly to me. My solution was to machine a delrin punch at a tapper to tap into the breach so that it grips the barrel and then I made a spanner that looks like a nut for tightening the muzzle.

[MonsterMaxx]

So...drill and tap into the little black piece that's spinning with the barrel?  I suppose I could do this under the sight to hide it.  How far does it stick in the gun?

[MonsterMaxx]

Well, I either fixed it or royally screwed up.  Found a m3 set screw, tap and bottoming tap.  Went under the rear sight, drilled down not all the way to the barrel, tapped and put a setscrew in.  Barrel tightened up then.  Now to put it back together...

You didn't remove the barrel first?
