What is it? CI

I was going to say that it looks like a tool for measuring your tool until I viewed more pictures after scrolling down. Now, I'm not sure.

581 looks very much like an early cylinder bore gauge.

583 A castellated nut.

584 Tobacco cutter?

585 Chain Loader Binder

Tom

Is that a drill or boring device?

Or is it Gort's tool? Gort! B'ringa! Woo Woo!

583. Castellated Nut

584. Drawn Knife

585. Forgot what they are called, you tighten loads on trucks with them.

582 is a book dart (clips onto page as a bookmark) 583 is a crown nut, used with a cotter pin 585 is a lever load binder

582. Paper clip book marks. 583. Castle Nut minus the cotter pin. 585. Chain cinch 586. Paint stirrer

582 clip for $ 584 work> Just posted this week's set:

#582: a brass or copper bookmark. It slides over the edge of the page.

That's it for me this time. Well, 583 is some sort of nut, but what kind I have no idea...

You mean 586, and I think it's a blower wheel... for something.

582. Bookmark 583. Self-threader 584. Tobacco cutter [needs board] 585. [Logging] chain tightener/clamp

581 - an inside micrometer that measures in fractions and a holder, possibly for bore measurements.

582 - page markers, copper, available from Lee Valley

583 - Castelated nut

586 - looks like a squirrel cage blower fan.

583: Castle nut - the bolt has a hole for a cotter pin, which goes through the appropriate slot, and holds the nut in place. 585: a "Come-along" - the two hooks hook to chains that need to have tension applied - the long handle gives you leverage, and the interesting clevis arrangement toggles and holds it in the retracted position. 586: looks like the end view of a small squirrel-cage blower.

581 - bore gauge 582 - paper dart 583 - castellated nut 3/8" 18 zinc plated 584 - Part of a tobacco cutter 584 - Chain binder 585 - mud mixer (can also be used for paint)

583 Not to start a pi**in' contest, but the correct term is "Castellated" nut, although commonly called castle nut. Most familiar use is in the front suspension & steering of cars/trucks to insure nothing vibrates loose. 585 Generally called a "chain binder" or "load binder", very familiar to anyone around the flatbed trucking business. Used to securely tie down those steel coils, loads of pipe, lumber, logs, etc. The long handle is indeed for extra leverage, but it's not enough when tying down a heavy load, which is why they make cheater bars, apiece of pipe about 3' long that you put over the handle to get the extra leverage needed.

According to R.H. :

O.K. As usual, posting from rec.crafts.metalworking:

581) Internal micrometer thimble, with a fixture to hold it where the measurement is needed.

It appears to be calibrated in fractional inch sizes, starting at 2-11/16" and going up to somewhere larger than 3-3/16".

The thimble looks to be calibrated in 1/16 of the 1/16" steps, or 1/256th of an inch.

Given the size range, and the presence of the word "oversizes" on the device, I would suggest that this was used for measuring the bores of engine cylinders.

582) Bookmarks, or to be set at the edge of a piece of paper, pointing to a particular line on the paper. 583) Castlelated nut -- used on a bolt or a stud with a cross-drilled hole and with a cotter pin placed through the hole between the projections and bent to hold it in position to prevent the nut from changing position. Commonly used when the proper setting is not tight enough to prevent the nut from shifting due to vibration. An example (though this is too small for that task) is the nut holding the outer bearing on a front wheel assembly of a car (without front-wheel drive). 584) It looks as though the loop to the right originally terminated in another handle, pointed parallel to the first, I suspect, and held in place by a screw, so the operator's hand is inside the curve.

Some kind of wood shaving tool, but I'm not sure what specific operation this particular shape is good for.

585) Load binder. The hooks hold chain links, and the handle pulls the two hooks closer together, to tighten a chain over a heavy piece of equipment on a flatbed trailer or similar situation, where you need the load to be firmly controlled so it does not slide off the trailer.

There are ratcheting devices for flat belts to perform similar functions, though with somewhat less force.

586) Hmm ... it is viewing into the end of a squirrel-cage blower, a rather small one. But I can't think of a specific tool on which this would be exposed as shown.

I guess that it (if run at a lower speed) might be good for stirring paint or something similar.

Or -- it might be held close to a fire you are trying to start, I guess.

----------------------------------------

Now, to see what others have guessed.

Enjoy, DoN.

I think that you're right. The hole in the end would thus secure it to the chopping block, allowing one hand to operate it, and the other hand to move the tobacco.

So my (already posted) answer is now more likely to be wrong.

Enjoy, DoN.

a "tool that can be found in most large hardware stores". It's a paint stirrer - I've seen one before...

Yeah, that was my first thought... I've seen that type of paint stir before. I suppose it just seemed *more* like a blower wheel... but you're probably right.
