Will be taking it out tonight for field testing :) Will keep you posted

Poorshot, When you get the bug, you are never happy and will keep trying to refining it :)

And I am hesitating taking my gun to bits to check lube and assembly!
 
Very impressive I would say.
 
What kind of end result will make you happy or are you just going to keep refining it?

thats all good then, bloody reflections on photos :)
Think that'd definately fall into the "open" or "high power" class, would make for a flatter trajectpry as well

ha ha yea :)

Update. Finished testing and i managed to get just over 350psi into the ram using an old fridge compressor. Fitted it back into the gun and fired a few rounds to see how it did.

I used the same tin of .22 RWS super dome that i used before.

Here is the results through the chrony.  I got around 20fps difference between shots. I will have to look at the  main shaft seal in the ram because i think the friction is causing the changes in the FPS. But all in all i am happy with the way the ram is sealing. It will need some tweaking but it is well on the way.

Nice work bud, if you'd had it together earlier it might have helped with your dragon problem :)]]> Fri, 01 Nov 2013 06:21:26 +0000 www.kiwiairgunners.co.nz/forum_posts.asp?TID=32&PID=333#333 Gas Ram conversions : Well i finished the new the end... www.kiwiairgunners.co.nz/forum_posts.asp?TID=32&PID=324#324 Author: nunga

Well i finished the new the end plug with the valve, sorry didnt take photos this time. Will do some pressure testing tomorrow and if all goes well i will put in the gun and see how it goes. But it is looking good so far.

This is my test tube with the inner tube valve  :) I have just figured out a cool little one way valve that wont take up space inside the tube so the piston shouldnt hit it.

I will try to get it done tonight because i have just been told that we are going away for the long weekend..... and the dragon-inlaw ops... my mother in law will be joining us.

Did some quick testing last night. machined up a test tube with a bike  inner tube valve  on one end to put some pressure in. I managed to get it to hold 90PSI with out any leaks. Then did a compression of the shaft and watched the pressure rise to 150 before the valve gave way. The seal its self it sweet i just need to work on the filling part. :)
