hi, where can i get discharge valve for AT44-10 air cylinder ?
Well Bob after a good night's sleep and some consideration..ive decided to instead only drill to 11/64". With some of the tight tolerances with oring seat placements I feel that this would be much safer choice. I can always go back and redrill if results aren't good enough. My fps goals aren't near what yours were on yours. I did however last night drill the delrin valve seat to 3/16" and replaced into valve. Out of fear of poppett not sealing and leaking I aired up tank and to my very pleasant surprise this morning im at full BAR. Thanks for your help, Trevor
Hey Rallyshark thanks for your valuable helpful advise. Would a small concave file be ok for transfer port? I'll try both it and your sandpaper tip. I'll go ahead while guns dismantled and open it up to 3/16". I've ordered some dremel pointed grinding stones to chamfur my valve. It lines up perfectly with transfer port but due to bit hanging seizing on raised ridge, chaumfer is necessary to allow bigger 3/16 bit to spin. As far as the delrin seat is concerned..that suckers drilled close to 3/16. I really drilled back and forth. Its back in valve and poppet doesnt leak..praise the Lord. I'm not removing it to redrill! Thanks again!!
;DHey Rallyshark me again. I got all passages drilled to 3/16"..even took out that delrin seat and gave er a good extra reaming. After what u said I thought about going up a size bit on it..but I didn't. Got TP to 3/16 using both file and SP then drill bit. Even got small valve holes all tapped and screwed and JB welded it up. One allen screw was in path of poppet..so I had to back it out a bit. Test screwed it into my Hatsan brass degasser tool and is smooth..no cutting or rubbing. Also screwed valve into position on gun and it is spot on PERFECT alignment..which brings me to this question. How necessary is it to chamfeur valve hole. I read that it was done due to hole not aligning perfect..but mine is. I can always do it later but i think im gonna leave well enough alone. Can't wait til daylight to get it out and CHRONY!!
