805: Ye Olde Adjustable Ratchet Wrench
806: Some sort of sampling tool?
807: Looks like an ordinary square pushbutton
808: Another typewriter repeair tool?
809: The holes and slots are possibly wire gauge scales. The press
part, maybe for crimping a seal over the wires...
810: Worlds worst pizza cutter
There's no such thing as a free lunch, but certain accounting practices can
result in a fully-depreciated one.
Hmm ... rather early, aren't you? I'm used to seeing them on
Thursday, but this set claims to have been posted on Monday. (Although
I did not see the usenet posting until Wednesday.)
Now I see a partial explanation at the bottom of the list of
objects to be guessed.
Anyway -- posting from rec.crafts.metalworking as usual.
805) An "any size -- Imperial or metric (or even Whitworth)" ratchet
The collar around the handle selects which direction the ratchet
You can work with the handle at strange angles to the bolt or
nut, but I'll bet that it would be prone to slip off the faces
of whatever you were trying to turn if you put much force on it.
806) Looks like a boring tool for fairly soft materials -- or
perhaps for ice.
The top T-handle should be pivoted so the shaft can turn in it,
and the middle T-handle, when pressed down, would rotate the
cutting bit in the proper direction to make the cut.
Hmm -- maybe not, blowing up the "arrowhead" shape at the end
seems to show that the head pivots on the shaft. In that case
perhaps it is to control a valve of some form, and the two side
"ears" on the middle 'T' pivot in some form of clamp, while you
turn the top T-handle. Maybe something like opening and closing
locks in a canal or something similar?
807) Perhaps part of a door and mounting frame for a tape drive or
perhaps a CD-ROM or DVD-ROM drive? The angle of the door is
808) I've never seen one of these before, but it looks to me to be a
tool for "gapping" a spark plug. The collection of feeler gauges
for setting the gap, the threads in the jaw to which the feelers
are pivoted hold the plug in place, and the "pecker" jaw presses
down on the movable/bendable point to bend it to the gap set by
the selected feeler gauge.
809) This one looks to be for clamping on the edge of sheet metal,
and guiding a drill bit vertically thorough the sheet metal.
The jaws of the pliers surrounding the hole will minimize
burring of the metal when the drill cuts through.
The notches are probably for starting a bend in the sheet metal.
810) I *think* that this is a valve spring compressor for some style
of automotive engine. It would hold the valve compressed, while
you remove or insert keepers to lock it in place.
Now to see what others have guessed.
