Anyone know where I can get a boot for an aluminium 7L flat bottomed
stage cylinder? Cylinder diameter is 1522mm

Bloody hell, that IS a big cylinder!

DOH - I meant 152mm :-)

I have seen them on pictures...and you can get boots for any size of
steel cylinder..but I can't find a 152mm for a 7 Litre Ali cylinder
anywhere

Errm... why do you want a boot? Given that they stand up on their
own accord...

Well it trashes the paint so the corrosion gets started quickly
but worst of all somebody might mistake you for a DIR diver.

the key is....they stand up nicely...but without a squared off boot,
they roll about the car and across carparks - but I can't find a boot
anywhere on Ebay or Google...so I guess they don't exist :-(

I've found that, being a diver, I tend to have a fair few lumps of lead
lying around and that they make pretty good chocks.

Or if you want to build something a bit more impressive you could try
and fashion something like this http://www.tanktrap.com out of some PVC
pipe and rope.

Don't do it.  I don't know if you guys have the foam "noodle" floats that
are very common here in Florida, but if you do, cut one of them up into
pieces, put holes in each end of each piece and run polly rope through them.
Secure them in place and set the spacing with knots and washers.

The foam holders are far superior to the PVC ones.  They grip the tank and
the surface they are sitting on and don't slide around easily as all, even
in the open bed of a pickup truck.  They cushion the tank against bumps and
won't scratch anything.  Best of all, they cost almost nothing if you make
one  yourself.  Mine are made for two tanks.  Here's one made for three.

I would have suggested "noodle" foam but it doesn't seem to be as
abundant here in the UK.  I agree that it would be a better material to
use.  After a quick search I found these

That's the stuff.  Interestingly, your link took me to the main page, not
the pate where the noodles are sold.  Choose Product Overview, Pools
(Paddling & Swimming) and look toward the bottom of the page.

Yup - this boot thing has become a challenge as I said "no problem, I
can find 152mm boots" to a bunch of friends in Italy....and I am
determined to find one (at least)

I didn't follow this thread from the beginning, so I can't be sure this has
not been mentioned before.

I don't recommend tank boots to those that dive in salt water except when
you just have to have them.  They tend to trap water and salt against the
metal at the bottom of the tank and hide any damage the salt may cause.
It's not a big risk, but there's very little reason to accept any risk for
flat bottom tanks.

Having said that, I have boots on my round bottom steel tanks.  For me, the
ability to stand them upright meets the "have to have" definition.  I am
particularly careful to rinse those tanks well and have the boots removed
every time the tanks are inspected.  So far, so good.

Yeah but if you have boots the paint doesn't get trashed so it
doesn't rust up anyhow. I know the people who do my tank inspections
pull the boots as the come back realigned so I dragged them off to
see what it was like and, after eight years, my twins are still
lovely smooth paint. When I consider some of the rusted up unbooted
tanks I see on dive boats, normally with an unsightly blotch of duct
tape on the bottoms I realise that my boots are probably putting
years on the life of the rig and doing wonders for the resale value.

Your tanks are painted?

Guess so.  You're a lot easier on your tanks than I am on mine.

I was going to ask "You sell tanks?" but I must admit to having sold a
couple of mine.  I need to sell more, but I just can't bring myself to part
with them.
