I'm holding off on them cos they are new and my cylinders have worn threads , so ...
Only done one Kevin .........called it cc1 cos it was the first of the chris cundy batch .
standard was pretty un special
went 90 odd bar then 88 finally went to mid 80s but creepy as hell .
Robs got some pics hopefully hell put them up for me . I deleted them off my phone .
there's a short vid of the fixed reg being fired off .
it's not very long either side of the shot so you'll have to trust me that it's stable ............check how quick it comes back
blimey that was fast i had'nt finished typing
Bloody odd that these brand new regs are just no-where near as stable as a fettled older one??...i think once we've got a conclusion Phil it would be good to get the feedback back to Steyr.
It seems queer mate .
I'll stick the others on tester shortly ...........Dont take my word for it, have a look yourself .
John Sawrey sent me his reg off a newish Challenge and it was poo on the checker. Started off at 85 bar and after 10 minutes or so had crept up to 90. I've had a play with it and got it much more stable but i still don't think it's acceptable...well for me anyway. I'm going to try a new piston and if that doesn't cure it see if i've got a
spare adjuster to swap out.
It's the tip seal mate .
which stack have you tried ? ................ ( both probably )
keep your old internals for me mate ............
Yep both.......i'll get it good......but we shouldn't need to do this level to get it decent, maybe it was a Freitag special.
That is as perfect as can be.
Mine don't recover near as quick as that. Creep is sorted but need to play some more to get recovery time down.
Waiting on DHL to deliver new o'rings all the way from the UK. This wonderful country of mine is useless when trying to find something out of the norm.
Just for interest.
First attempt to cleanup the piston seal on my heavy varmint (120 bar, 20 ft lb) regulator was done by hand.
I worked the seal in a figure of eight on a piece of 800 grit paper. Don't know if I will ever be able to repeat it, but it seals perfectly with tube removed.
I have on two separate occasions now, fired a shot with tube removed at target 25m away. One hit the X and the other hit 5mm below aim point.
I can leave this rifle stored overnight without the reg releasing air.
It's all about the seal Kevin
Been stood a few days now
Pressure higher than previous photos
It s warm today
I only wish. I can get the fast response which I am happy about, but I cant get the seal.
What did you do to make the seal perfect?
I can get the reg to respond after a cycle instantly. I do not get the perfect seal whereby with the removal of the high pressure the reg remains sealed and at pressure.
Don't worry about it Errol.
It don't mean diddly.
You've got the important stuff working
I can get them to hold air but return slow and creep .....................figure that one out
Slow closing piston
I'll make a note
" Note : Ignore Rob "
Sorry for the messy table.
