3076.. I have a blade brazer similar to the one pictured.
The one I have is larger, has a 120VAC power cord and a selector switch for
Off-Lo-Med-Hi on the side.
I wasn't able to see any electrical isolation between one side holder and
the case, in this week's example.
An electrical model contains a large step-down transformer with the
secondary winding typically being only a couple of wraps around the primary
winding, so the secondary voltage is very low (similar to a resistance
The projecting arms (to the left and right) align the back edge of the blade
in a straight line, and the 2 clamps hold the prepared ends of the bandsaw
blade in close contact.
A small strip of silver foil was placed in the repair spot, and when the
handle was pulled down, the transformer was energized and an anvil of sorts
integrated into the handle pressed down to apply pressure to the splice to
maintain the proper blade thickness.
Thanks for the information, seems pretty similar to the one on my site.
No luck yet identifying the first two items, answers for the other four can be
I agree that I can't see any kind of electrical insulation, so
it might be that it was heated by a torch instead.
And in operation, it is somewhat similar to the bandsaw blade
welders -- except that it uses silver solder (brazing) instead of
resistance welding -- and thus requires overlapping surfaces instead of
placing the ends of the bandsaw blade against each other and pumping
lots of current through them to melt the ends and fuse them. (After
that, they need a grinder to clear off the flash which oozes out. :-)
As for 3075 -- the old ice trays which I knew had built-in
levers to break the ice cubes free of the dividers. I would guess that
you could get more trays into a given freezer compartment if the lever
And for 3078 -- when you said "an outdoorsman", I was thinking
that you were implying that it was to be *used* outdoors. I see from
the later photo added that it was used with full brass shotshells, not
the later paper and then plastic ones. Though I guess that it could be
used for all.
And at least one other came up with a similar description of its
Well ... in Austrailia, there is little chance that I could put
my hands on it for an examination, then. :-)
Scraping the ice from block to go into a drink, perhaps?
The shape of the guides and clamps was what led me to that

Hmm ... shotgun shells? Perhaps on a table during clay pigeon
shooting, perhaps? Two rows, a double-barreled shotgun and it might
be fairly convenient for quick reloads. I don't really know the proper
diameters of the various gauges of shells, but that might work.
I am interested in which newsgroup has the greatest number of
correct identifications for each class of objects. I can't develop that
information until I know where people are posting from -- since there is
no clue in the headers. I provide the information by way of example,
hoping that others will do the same.
I've expanded the wording because of some who post saying "from
my computer" or something similarly uninformative.
How many post only in one group, instead of doing a normal
"followup", which would go to all three newsgroups? I don't see any in
rec.crafts.metalworking -- though I must admit to not
specifically looking for that. Granted, I have to deal with my
newsreader saying "are you sure?" each time, and suggesting that I set
the "Followup-To: " to a single newsgroup -- but if I did that, a number
would not see what I post, and perhaps augment my guesses with more
knowledge. I *hope* that everybody posts to all three newsgroups.
And I certainly don't go to the other two newsgroups. I spend
enough time on the net as it is, between a few newsgroups, some mailing
lists, and private e-mail. :-)
Well ... I'm hardly *imposing* it. I am in no position to force
anyone to comply (nor would I *want* to). How much "power" I have is
indicated by how many others indicate which newsgroup they are posting
Mostly, I expect that people in specific newsgroups would be
more likely to get certain categories of puzzle photos properly
identified. For example, I am not a woodworker, and don't expect to get
many of the more esoteric woodworking tools correct. But I am a
metalworker (hobby level), and am a retired electronics technician (but
there is no cross-posting to the electronics newsgroups).
I am particularly interested in seeing how many of those who
find this in the puzzles newsgroup (and who do not read the other
newsgroups) get various technical items correctly.
