According to R.H. :
A new set has been posted, thanks to those who emailed and posted feedback
about the site, there might be additional minor changes coming in the

O.K. As always, posting from rec.crafts.metalworking.

600) A wrench for tightening Swageloc "flare" fittings. The rollers
will be pushed back in one direction, but will press firmly
against the flats in the other direction, giving it a ratcheting
action, without needing to be properly aligned on insertion as a
normal box wrench would require.

I've got one with two sizes on two ends -- for the 1/4" fittings
and for the 5/16" fittings.

Note that they are not truly flare fittings, but they are used
in the sorts of places where a flare fitting would be used.

The open part of the 'C' shape allows it to be slipped over the
tubing both before and after tightening, so you don't wind up
with an expensive wrench trapped on the tubing. :-)

601) Either some kind of steel quarrel for a crossbown, or a
variation on the "lazy dog" anti-personell devices dropped from
a high-flying aircraft, letting the long fall build up the
kinetic energy to injure or kill someone.

The ones which I have seen were smaller and made of lead. These
may be intended to penetrate something more solid than a person.

602) I find it hard to imagine this beeing driven into wood without
maring the finish on the head.

Offhand, I would think that it is for looping a rope over, or
perhaps for hanging clothes from, and it should be pressed into
a pre-drilled hole, not driven in with a sledgehammer.

603) A bootjack! Used for removing cowboy boots. One foot is
placed on top of the ramp to hold it down, and the heel of the
boot on the other foot is placed in the notch to hold the boot
while the foot is withdrawn.

604) Hmm ... I've never seen one, but I suspect that this may be a
perforating charge -- an explosive set off in the bottom most
section of the pipe in a drilled well, to perforate the walls to
allow the water (or oil, depending on the well) to flow in.

605) No guess at all on this one.

Now to see what others have already answered.

Enjoy,
DoN.
