Air rifle cylinder laws?

[dave blakemore]

when i first started to make my rifles 20 years ago, i made the cylinder, and submited it to Lloyds british to have it tested and to see if the way i had constructed it was correct, even though i tested it myself, its always best to get it checked by people who specialise it that field, and get there oppinion.

i can only presume other manufactures have done the same, but i was once asked by a big manufacturer how i tested my cylinders, and could i make them the the same type of testing gear i use, when i asked how had they been testing them, there answer was, they did'nt when i questioned them regarding testing they had not got a clue, frightning, i can only hope they have advanced somewhat.

You are not referring to a manufacturer based in Stone by any chance Shaun......

I doubt if any of the cylinders in your guns would burst, 1/8 thick wall on a 1 inch od cylinder, Jesus wept, no wonder they weigh a ton

25x3 Dave same as first one i made. 1/2" BSP threads.

All mine hand made one offs were individually tested, Saun will know that at 6300 psi it sheared a rated 10000 psi grease gun 1/8"BSP nipple.

Those that say its up to the individual whether to use or not is irrelevant, its the manufacturer for not designing and producing correctly saving 10p on a tube and 1/4Lb in weight!
How many have even done a single test, destructive or otherwise yet alone test every cylinder and bought in the thousands!

Seen plenty of bad designs over the years, tube it self may have been strong enough but how the valves attached is a different matter. I could real a load straight off from UK, US and chinky. More importantly its a danger to others around not the users!
We wont mention the QF conversions threaded into Luxfer bottles, thats the mentality and exactly same principles apply to all above.
