Tuning Cobra valve tech built into raw valve

Well so far I'm working on getting the poppet to seal I'm going to have to lapp it more didn't do it enough I guess the chamber has 2 .025 vent holes in it from what I can tell it is slamming shut fast using a really light valve spring just so poppet closes when gun is empty after that air pressure takes over to slam the valve shut vent holes may need to be enlarged to get more dwell for power it's coming along 

That's the valve spring by the hammer .010 wire

Well my dumb idea was to open up the hammer more so my ssg was not hang up in it so spent 3 hours making a new hammer and polishing it but no more ssg getting stuck in the back of it it is 61 grams it's a little tighter fitting than the old one was to 

The one picture at the tip of the caliper you can see the .025 vent hole there are 2 of them I have to lap the valve in more it isn't quite sealing all the way any suggestions I'm using a drill with good metal polish and spinning the poppet in the valve both ways fast as the sell will go and then clean everything up and retry I've done it twice now and has gotten better each time idk

Outer dimension of the tube 

How it fits in the gun 

Peek poppet dimensions

Length of the tube chamber dimensions and outer dimension of the tube 

.025 vent hole there is 2 of them and how much I took off the blanking plug spring guide the other part of it is driven into the tube to hold it in place and straight

The cobra valve is working and shutting fast just have a small leak at poppet sealing to valve yet I need more air in my tank before I can fill it completely but I have enough to get over the 150 bar where the reg is set at I haven't tried to Chrono it yet I want to get the small leak sealed up first Dry fired it from 3000 psi down under the reg leak doesn't get any worse till about 90 bar then quickly filled it again tried it several times still can hear it hissing enough to drive a person mad lol dry fired at least 50 times hoping it would seal up 

I will thanks 

I'm going to have to make a new poppet with a different sealing angle and take it to .320 for more closing force just can't get this one to seal all the way up frustrated with it right now my first on I made sealed up with very little lapping but it also was using a heavier valve spring

Yeah I know sometimes I get rushing things I think Im going to need change the angle of the sealing surface so there is more of it and go up to .320 .325 for a little more sealing pressure . The poppet doesn't have much surface to change the angle it's only about a .060 or a tad thicker at the sealing point. trial and error I guess is how we learn

At least I have length of the poppet and chamber size to go off of which will help

Made a new poppet went to .325 35 degree sealing angle still using same chamber just changed the depth to .500 deep so poppet won't bottom out being it's a tad longer with spring guide on it
