What is it? Set 279

Is there an "American standard wire gauge"?

I tried AWG first but the ratios were all wrong. We know from the photo that 1/3 of 00 gauge should be about 10.7 gauge, but that doesn't even come close to AWG.

British or Imperial Standard Wire Gauge does have the right ratios, as does Birmingham and Stubbs, but AWG can't be right. In the middle range a lot of gauges were fairly close to BSWG and I can't really rule them out either.

It is a silly thought, but it would be amusing to contemplate this door-knocker coupled to a delay/amplifier so that if it were struck it would produce the ting-Clang of a blacksmith/apprentice strike.

1586: For transferring a dimension of some sort, not sure what. 1587: Perhaps for installing an escutchen plate over a lock handle. 1588: A hammer and anvil. If the hammer is attached to the horn I imagine this is some sort of modified piece, as it would make the horn useless. Or it is possibly intended as a musical instrument rather than a metalworking tool (in which case the horn shape is merely decorative) 1589: Possibly a fancy plumb bob... 1590: some sort of specialized thickness gauge.

I think 1585 looks much more like it is up side down. I'm betting it is for picking up something of fairly uniform thickness like heavy plate that only holds while the load is in tension. I know it is not the typical ice tong type and I would worry about picking something as slick as steel plate. bit I don't see its use in rigging or rope work of any type.

I just heard back about your second question, the metal part does unscrew from the handle.

Also the observable fact that the larger numbers come with the smaller gap, which is common with wire and sheet metal gauges, which are smaller the more times they have passed through drawing dies or between rollers. To measure in "Oz" (unless you mean in Australia :-) you would need the numbers to increase as the gap increases.

Also -- if it were reading in 64ths of an inch, the numbers would be equally spaced, instead of getting more widely spaced as the numbers get smaller.

Aside form that, given the rather steep observable angle of the threads, we would need to know how many "starts" (parallel interleaved threads).

Enjoy, DoN.

How about "jam cleat"?

Yes -- but the material is wrong for sailboat use. It is drop forged steel -- and would rust like mad in such an environment. For a sailboat, the materials should be either bronze or a tough plastic like Delrin -- perhaps with internal parts of stainless steel, if there were springs which are common in actual jam cleats.

Nope -- not given the thin anvil, the material, and the mounting holes. It petty much *has* to be a blacksmith's door knocker.

I *think* sheet metal, but I'm not positive.

Enjoy, DoN.
