Does anybody recognize this regulator?

[mcoulter]

Got this in a tube with a used AT44.  Best guess is that it's a older Audrius.  Has anyone seen one of these before? 

They look different from the Audrius regs I see on ebay.  (BTW, there is a spacer, I just didn't take a photo of it...)

It looks a lot like my Lane.

100% looks like a Robert Lane regulator.

[TroyHammer]

It is definitely a Lane Reg.

Awesome!  Thanks everyone!

[Motorhead]

Yup ... LANE

[Rocker1]

Lane for sure. David

Well, that answers that question and now I know which one is installed in my .22 AT44!  LOL!  I knew I had one of each, just couldn't remember which one went where, now I know!  Thanks and have fun!

Yep, Lane again! LOL!!!

Thanks again guys.  After assembling the gun again, the light was bad enough that my Prochono would not read and the cheap ($25) illuminated Chinese seemed to be having issues, I don't have a good current string.  The numbers I was getting were all over the place which are not consistent with the grouping.  My best guess is that it's shooting around 930 fps with .177 CPUM pellets.  (Hammer spring is at 5 turns out.)

This gun in consistently shooting 10-shot groups like this at 32 yards with 10.3 CPUMs... Oh, almost forgot to mention that what blew me away is that this is the group I got - which is RIGHT on target - after a taking it down nearly completely and reassembling it again! I thought for sure that I would have to make some scope adjustment...  guess not!

Nice shooting Matt!  Looks like you've got it dialed in!

Can anyone advise on how to estimate the "Regulated CC" in Triggertreat's spreadsheet?  I wish I had some measurement of what the spacer length is...  but I don't. 

Again this is a Lane Regulator in a Hatsan AT44 tube (not long).  Here's a recent string from it.  It looks like the regulator is set at about 120 Bar (1740 psi).  I did discover that the hammer spring adjustment was moving while shooting.  I added a few drops of vibratite on the threads.  Hopefully this will keep it steady...  I currently have it set to 4 turns out.

Is this possibly what you are looking for?

[mcoulter]

Hi Paul,  I'm really not sure.  My assumption is that the measurement I want is  the volume in the chamber (plenum?) between the valve and the regulator...

And for reference here is the unregulated tube at the same hammer spring setting...

[Rat Sniper (AKA: PaulT58)]

I would think you could measure the volume of the Plenum in the same manner they did the valve in the video.  Filling it with water while attached to the regulator and then measuring how much water was added should give you a fairly close estimate.  If you want a more accurate measurement, you could measure the size of the part of the valve that would be inside the plenum area and then subtract that from the measurement you got from filling the plenum.  As the video pointed out, the water isn't in there for very long and just be sure to allow it to dry before reassembling it.  I always just left that field blank because I have no clue what it was!  LOL!  The other option would be to contact Lane (airgun.regulators@aol.co.uk) and ask them.  They are usually pretty responsive to e-mails.
