Did some tinkering today...
« on: October 24, 2009, 03:00:29 PM »
On a couple of different rifles.  First, it looks like I've FINALLY fixed the air leak in my Hammerli Pneuma.  The last time I had the valve apart, it occurred to me that the delrin (?) valve seat in the valve could be letting air leak past it, it's just a friction fit in the valve body.  So today I laid a bead of super glue around the seat and let it set up.  Filled it to 2K psi and let it sit.  It's been several hours and the needle hasn't budged.  Before, it would start leaking immediately, after this much time I'd definitely have lost a couple of hundred psi.  Will know for sure come morning.

Next up, some trigger work on the Diana 46E.  This has the older T01 trigger, which IMO is a much better trigger than the T05.  However, mine was feeling a bit rough and gritty, and I was having some adjustment issues.  So, tore it all down, cleaned, polished, and lubed, and was able to do some initial adjustment with the trigger assembly out of the rifle.  Put it all back together, tweaked it a little more, and MAN this thing is sweet!  Reasonably short 1st stage, nice stop, and then a very clean, crisp break on the second stage.  Don't have a trigger gauge, but I'd say about 2 lbs.  Not in the same class as the trigger on my S200, but it's every bit as good as a Rekord IMO.  I could lighten it up some more, but since this is in a springer, I like it right where it is :-).  Now if I could just get the time to run this thing over the chrony again...  Maybe tomorrow.  BTW, for anyone interested in working on this particular trigger, here is a link to an outstanding pictorial tutorial: http://www.network54.com/Forum/79537/message/1227043001/Diana+48-52++T01+trigger+disassembly-assembly++%28picture+warning%29  Not a lot of text, but the pics are incredible, so it's really not needed.   Later.
