Right.
So frustrated it was about making me climb the proverbial wall and then.... this finally saw its solution.

Before that though i´ve ripped it all apart and put it back together like 10 times trying to get a grasp on what´s going on and.. solution was there all the time. Right in front of me.

As the intent here is to "ride the jagged edge" as the time comes ports have been opened up beyond sanity even. Valve and poppet reworked completely and what not.. So this thing´ll flow some air alright.

I´ve worked on the hammer too. Making the spring pocket deeper in the end and the hammer lighter. Started out at 68 grams, but seeing the rather limited stretch allowed for acceleration of it them 68 struck me as rather.. much.
The stock spring in turn, 8,5mm outer diameter and wound on 1.0mm wire. Spring is set in a SSG setup. Played around with some other, similar, springs but..
This thing had me beat. Until i opened the pocket of that hammer up to take 10mm dia springs and shoved an eeeeeeeever so slightly stiffer spring in there.
Bingo.
Still just about as light to cock, but muzzle speeds jumped an easy 60fps without even trying. Where i´m at at the moment that hammer weighs in at 50 grams flat, and truth be told i´m where i´m at now real pleased with that being done.
If we set speed vs weight speed will, as per the pills we use, win every time. So in short this was a matter of lack of hammer acceleration in short.

We´ve got the place that delivers all the springs for FX here in town so due that above there i´m going to pay them a visit come tomorrow. Since previous i´ve bought a few Impact springs from them for use as hammer springs on old French Mle 1866 Chassepot rifles.
Thus i´m all to aware that the spring i´ve got in mind, which is the stock piece for the "power plenum" upgrade, is wound on a 1,4mm wire and at 10mm outer.

Seeing the porting work done and so on i now honestly believe we´ll get this thing super sonic at will, which i have no interest in what so ever. Thus this thing will get tuned to "lick the wall" with 25,4´s for starters.
Then it´s regulator order time and as that piece shows i´m going to fab an approx 80cc plenum for it too. From thereon out in turn i hope i´ll "survive" for the most part on the porting already done as the idea here is to start shoving 34 grain 22cal pills down the throat of it.

Have actually ordered a box of the ZA made "Javelins" for my 22´s.. we´ll see where that takes me.

But. Finally arrived. Been a long time coming it feels like so.. kind of sweet "victory" to me this cause DAMN this has had me climbing the walls at the shop!
I´ll tell ya that much!

All well that ends well though.
