In firearms, scope rails are generally attached with (short) screws, and I've done the same thing myself.
(though I have seen mounts machined into the barrel)

<i>Much</i> less ugly than hose clamps.

Hey those scope mounts aren't for attaching rails to your gun, they are not for attaching the rail to the gun they are for attaching scopes to the rail
I just don't want anyone make a pointless buy,

BLB: I don't think most of us feel safe screwing into the chamber although they are short screws, and it doesn't sound easy with steel

If 1" steel pipe was to be rated by it's burst pressure in the same way as PVC, it'd be reasonable to expect a rating of 2000 PSI or so.

Perhaps you don't <i>feel</i> safe doing it, but such emotions are probably borderline phobia.

Not <i>easy</i>... but it's not hard-tempered, nor an exotic (or even stainless) alloy, so (provided you have a tap) it's not exactly difficult.
You just have to be careful and paitient - but that's the case with anything, even aluminum.

(As an anecdote, one of my friends knows someone who snapped off a decent-sized tap in aluminum... as I said, patience is often a virtue when tapping.)

I've never seen taps so tiny, but mainly I'd just be worried about leaks

Perhaps you could put a gasket between the rail and the fitting?
Such practices seem to work ok in diaphragm construction.
