One of my most used tools in the garage is my compressor as an air
blower. But I keep thinking how much I would like a portable version..
SOmething like a "Recharable Air Blower" which I could fill from my
compressor.

As an ex-diver, I had an idea.. I have a small (perhaps 1/2l) air
bottle and I figured that with the correct fittings, I could connect
it to my cylinder and fill it. As my project developed, I realised
that if I fitted a standard 'quick release' fitting to the top of the
bottle. I could use it to power ANY tool.. Obviously its not going to
give much air, but certainly enough to drive in a few staples for
example.

The idea is sound, but trying to get the fittings has proved
impossible.

The thread in the bottle is 7/10" (not sure if 7/10" is right, but
thats what my calipers say it is) but no-one that I have found stocks
anyhting like this, which will convert to BSP.. Once its in a BSP
thread, I already have plenty of adaptors which will let me hook it
up.

So, the question is, can I get a adaptor to convert the thread on the
bottle to BSP?

If not, where could I get a small bottle (1L) which is capable of
holding a measly 8bar which has a suitable thread?

I look forwards to your thoughts

What would normally screw into your gas bottle? Can you get a fitting with
the right thread onto which you could braze a short length of copper pipe,
with a BSP fitting at the other end?
