Fatcatsplat Posted June 18, 2010 Report Share Posted June 18, 2010 Got myself an S410 TDR off young Stubby on here the other week and it is an absolutely fantastic piece of kit - Have used it on targets and bunnies and works like a dream. However.........Filling it up yesterday, i filled it up to 200 on the meter and then turned the tank off, but left the nozzle connected. Only trouble is that it wasn't exactly off, which i discovered about 10 minutes later when, with a very loud bang, the hose disconnected from the gun!! The pressure was reading way past the clock and i fired off a bundle of pellets to try to take the poundage down. The first 20 shots were extremely low power and as the pressure dropped, the power seemed to increase and it's back on form now. It doesn't seem to have done any damage, but am wondering what damage it could have done - Any ideas? Quote Link to comment Share on other sites More sharing options...
Spaniel Posted June 18, 2010 Report Share Posted June 18, 2010 Only filled S410 up the once so far but was told to go no where near the 200 mark, but i cant remember what the pressure was as it was done down the dive shop.......anyone got any ideas on max pressure to fill these ?

Al Downie Posted June 18, 2010 Report Share Posted June 18, 2010 Check the fill-valve - could be that if the hose has blasted off it once, the connector might not hold for 'normal' filling from now on. Quote Link to comment Share on other sites More sharing options...
Dougy Posted June 18, 2010 Report Share Posted June 18, 2010 (edited) what Bar is the bottle not 300 i hope I would have thought that it would of equalized if it was say 232 before any damage was done, i am refering to the actual res on the rifle not valves, as the gun would need to have a test pressure considerably more than the reccomended fill pressure, could have been rather nasty, still lesson learnt bet you dont do it again i can see webber adding to this, he's the man Edited June 18, 2010 by Dougy Quote Link to comment Share on other sites More sharing options...

Over that and the first 15 or so shots are less powerful and less accurate. Test it yourself and see. Hope this helps. Quote Link to comment Share on other sites More sharing options...
alexr Posted June 18, 2010 Report Share Posted June 18, 2010 Don't rely on the gage on the rifle. Use the gage on the bottle your filling off. Its more accurate, or at least easier to read I would hope, also there can be a slight delay in the needle coming round on the gage on the gun. This could lead to you repeatedly over filling the gun. I have always seen the gage on the gun as a way of checking the charge prior to use, rather than an aid to filling. Quote Link to comment Share on other sites More sharing options...

Colster Posted June 18, 2010 Report Share Posted June 18, 2010 (edited) My S400 Xtra (would imagine 410 is the same) has a safety baffle in the cylinder that breaks at 250Bar, this renders the cylinder unusable but stops bits exploding. Sounds like you haven't damaged that as it wouldn't hold air at all afterwards if that had gone. Edited June 18, 2010 by Colster Quote Link to comment Share on other sites More sharing options...

nasher Posted June 23, 2010 Report Share Posted June 23, 2010 The SWP (safe working pressure) is 190 bar when the gun is tested after the seals are done its pumped up to 210-220bar, the reason the first few shots were low is the pressure holding the hammer spring back and not letting enough air through, if your fill bottle is a 232 bar one you would be alright, also if you have a 300bar bottle dont forget its only 300bar when its first filled and drops after every gun fill, also if you had put 300bar into it you would have ruined the cylinder the valve would have blow the end of the cylinder flares and you need £300 to sort it. atb nasher Quote Link to comment Share on other sites More sharing options...

johnbaz Posted June 23, 2010 Report Share Posted June 23, 2010 Hi I once overfilled my Daystate Huntsman Mk1, the fill pressure was 2000psi, i can't remember what i put in but like yours, the power was down quite a bit, after i had dry fired it quite times it was fine, as already said the hammer can't open the valve due to the high pressure pushing against it.. mine is fine and was over ten years since it happened..

SSS Posted June 23, 2010 Report Share Posted June 23, 2010 Looks like a trip to the menders then as the bottle is 300 bar and had just come back from being filled and tested - Oops! I thought they had reduced all dive bottle pressures to 232 bar for safety reasons? Quote Link to comment Share on other sites More sharing options...
Billy. Posted June 23, 2010 Report Share Posted June 23, 2010 I think you'll find the transfer port will have limited the amount of air it could transfer from the pcp tank to the chamber. I'm not too hot on the subject of airguns, but I think this is the case. Nevertheless, the tank you will have filled it from will not have been more than 232 bar (unless you are using specialist equipment) which I can guarantee will be accounted for by the manufacturers. If it says it has a max working pressure of 200 bar, it'll explode at something like 300. They'll always have to give a large margin of error for these things.

Hi Billy I vaguely recall a Ripley rifle cylinder being tested to destruction- it was taken to somewhere around 13,000 PSI before it blew :unsure: , i think they have to have a massive margin for error due to most users getting complacent regarding the dangers of HPA... :unsure: BTW, the Ripley test took place in a padded room!!! Cheers, John :blink: SSS, my cylinder is a 300bar surface air tank, test is every five years, i'm sure that the lower pressure cylinders were in use before the 300bar ones..

BattleFieldRelics Posted June 24, 2010 Report Share Posted June 24, 2010 Blew my s410 years ago when I first got it. (too keen) Anyway after 24 hours it reseated and it was happy times for the next four years :unsure: Quote Link to comment Share on other sites More sharing options...
nasher Posted June 28, 2010 Report Share Posted June 28, 2010 You can buy 300bar bottles easier than 232bar bottles these days and if your shop will only fill it to 232bar its their filling equipment limit, my local gunshops compressor only fills to 232bar so I take it to a dive shop which fills it to 300. It was in the aformentioned gunshop that I saw a S410 come in with its cylinder completely wrecked from overfilling the end was flared out and was no longer usable but as the original poster says his is still working then we can assume he has got away with it. atb nasher Quote Link to comment Share on other sites More sharing options...
Billy. Posted June 28, 2010 Report Share Posted June 28, 2010 New to me. I only thought the 300 bar stuff was specialist equipment and it doesn't surprise me that places wont go past 232 bar. 300 bar for an airgun is pushing it a bit for my liking.

artschool Posted June 28, 2010 Report Share Posted June 28, 2010 my bottle is 300bar and i fill at a dive shop to 300 bar. i would have thought you get more fills from a higher pressure bottle, making it worthwhile? Quote Link to comment Share on other sites More sharing options...

I may be wrong, but it was what I was told Hmmm-you may be correct as the only way i suppose is to screw a solid 1/8 bsp screw into the hose then open the valve and see what the guage says.. When i charge my guns, 200 bar is the highest pressure that any of my guns take so it's never been fully opened :blink: Cheers, John Quote Link to comment Share on other sites More sharing options...
12/ou Posted July 8, 2010 Report Share Posted July 8, 2010 i'd only fill to about 180bar. be safe. Quote Link to comment Share on other sites More sharing options...
