In case you missed it... Geezer???

The third tool hanging on the wall is a 2 man bucksaw. Before the chainsaw, they would have been used for cutting down trees, cutting up logs, firewood, and etc. They are still used in wildernesses where motorized engines are prohibited.

The first tool is called a spider, and is used to check the set of the tooth as is shown in this ...sorry, you cannot view external links. To see them, please REGISTER or LOGIN

Every 5^th (double) tooth on the saws above is called a raker tooth. They remain flat (no set).

The second tool is used to measure the depth of these raker teeth.

I was told that this was used to gauge the flatness of stuff (granite tables?), although I'm not sure it wasn't also used for grinding. My goal is to eventually make it into a telescope.

It must be an axe that can be used by right or left-handed people. Why else would it have two cutting edges (unless it's for chopping down two trees at the same time?)

I believe this is a double-bit axe.
It is used to Perform the same function as single-bit axe, only difference is it has two cutting edges one on each end of the head so that the lumbermen or person using the axe can rotate it in their hand and use both edges.. I believe the marks are the falling count.. how many trees its cut down.. but thats just kinda what I remember as a kid hearing. It was a long time ago so I can't be sure that my memory is correct.LOL

The Double-bit axes have straight handles that are symmetrical with the double-edge head.
I know one type or pattern head is called a western and then I think we used to have one that was refereed to as a reversible head. There are likely more but those are the types I have seen around here.
We are in the land of lumberjacks and most of them use the double bit axe wen downing trees and working with the logs.. ect

The hot axe blade when being reforged / re-tempered?

CliffordK · « **Reply #718 on:** 16/09/2011 04:33:13 »

I've sharpened axes... but never retempered them.

Single blade axes suffer from being used as sledges and wedges, but that isn't an issue with double-bitted axes.

I doubt that anybody has whacked into railroad irons or something enough times to warrant multiple major rebuilds of the axe head without also breaking the handle.

imatfaal · « **Reply #719 on:** 16/09/2011 11:52:38 »

Old steel would blunt quickly after much use - my uncle used to get his chisels redone (he was a cabinet maker since before wwii - now sadly gone). He claimed that over time the whacking used to make all the steel the same all over - the body of the chisel would go brittle from being soft and flexible and the tip would become soft from being hard and brittle. whether this was an old wives tale I do not know

Never heard that one before. I think it's a bit suspect, but maybe he was right. If he was in the habit of using a grinding wheel to sharpen them, the heat produced could affect the hardness, but it's more usual to sharpen them on a stone by hand.

Wot we need is a meta-lurgy-cal person to 'splain this to us.

I don't think axe heads are hardened that much. Last time I sharpened my hand axe, I seem to remember I used a file, then a stone to put the final edge on it.

CliffordK · « **Reply #721 on:** 18/09/2011 05:36:10 »

Ok,

I think we got sidetracked a bit. So much for woodsy stuff.

Anyway, the axe in the photo above is a feller's (or faller's) axe. The flat edge on the bottom is supposed to make the axe into a T-Square that can be used to determine the direction a tree will fall. What if the axe handle is warped as above?

...sorry, you cannot view external links. To see them, please REGISTER or LOGIN

As far as the notches. I thought I was told that it was providing a guide for the crosscut saw while cutting down the trees, but the best I can tell, it has to do with underbucking with a buck saw.

...sorry, you cannot view external links. To see them, please REGISTER or LOGIN

Although the Wikipedia article does suggest using a single-bit axe, presumably so you won't fall into the axe head.

As mentioned, it will give a crude count of the number of underbucks that have been done.

Geezer suggested a burnt effect, but it would be friction burning.

Good question. And, it does appear to be graphite, or a high carbon compound. And it did chip when I dropped it. The screw appears to be a copper alloy (copper, brass, or bronze), and does not come out the other end.

It appears as if Geezer is on the right track....

As far as the pulley, it is light (which is good), but as mentioned, it chipped easily when dropped, and the screw doesn't seem strong enough to take much abuse. So, I'm doubtful.

I haven't tried scraping it, but if it is carbon, it would likely crumble more than a whetstone. It also has a gear tooth like shape that would be inconvenient for sharpening many items.

Geezer? Your thoughts?

The battery post is down my line of reasoning, The carbon part reminds me of the carbon rod that one finds in the middle of typical alkaline batteries, just much bigger.

The screw reminds me of the screw-on top on many 6V lantern batteries.

Unfortunately I haven't taken apart many larger alkaline batteries. At about 6" long, it would be tall for a lantern battery, and everything I see indicate that at least the modern 6V batteries are made of multiple independent smaller cells wired together.

Geezer · « **Reply #729 on:** 23/09/2011 17:09:03 »

I was thinking it might be a brush for a large dynamo or motor. The fluted section is likely to prevent rotation, which is required with a brush.

CliffordK · « **Reply #730 on:** 23/09/2011 18:31:19 »

Interesting idea. The end is flat and not worn concave. However, it doesn't mean it isn't new. The profile, however, is round (with flutes). Most brushes I've seen are square or rectangular because they are designed to match the shape of the commutator.

The piece was found in the mountains near a long abandoned remote homestead which is also in a mining region.

The voltage put out by a galvanic cell depends on the chemical reaction that takes place when electricity is generated. The maximum possible for any practical system is around 2.5 volt, and most of the practical cells produce about 1.5 volt. (Lead-Acid as in a car battery is 2.0 volt). So any 6 volt battery must consist of 3 or 4 cells wired in series.

But we are here looking at a rather old artifact, so 6 volt is probably rather irrelevant. I think that Bored Chemist's suggestion

The fluted profile is consistent with trying to maximise the surface area of an electrode, while maintaining the mechanical integrity of a rather fragile material.

Awww heck,
I just use my meter as a go/no-go gauge.

Anyway, the resistance in the wires of the meter seems to be about 0.3 ohms.
The resistance from end to end on the "handle" seems to be about 0.8 ohms, or a difference of about 0.5 ohms.

I may have to do some polishing as I seem to get some very high resistance across the screw.

Isn't there a lttle thingy you can adjust to zero the reading? Either that, or you are needing to change the battery before it leaks and ruins your meter [

If it's about 0.5 Ω, it does sound a bit high for a motor brush, so that would suggest it's the carbon electrode for a primary cell as BC and the dangly sword guy suggest.

Perhaps this was not quite what it seemed. Not a celebration of the turn of the millennium, but a doomsday prediction that we would all be using candles after the millennium bug put an end to life as we ~~know~~ knew it.

CliffordK · « **Reply #742 on:** 10/03/2012 12:02:49 »

Ok, not much in the comments about the Candle.

In the late 90's, people became aware of a potential issue with dates, in that if the year was written with two digits (99), then the new year (00) would have a couple of issues.

00 < 99, rather than being larger than the previous year.
If one simply incremented the value for the year, 99+1 = 100, which could cause a number of unexpected errors when one is expecting a 2 digit date.
Dates might be calculated by concatenating the strings 19+the 2 digit year, so the new year might read 1900, or 19100.

This became known as the ...sorry, you cannot view external links. To see them, please REGISTER or LOGIN

Anyway, so there was a huge effort to clean up the code.... so that programs would work properly on the new year. Many companies such as Microsoft released special Y2K patches.

Nonetheless, there were many people who were convinced that there would be a critical failure, such as a loss of major public utilities such as electricity. Oregon Health Sciences University rented a huge semi-truck generator and wired it into their electrical system as a precaution.

Of course, there were a number of other people who weren't convinced that power would be lost, but perhaps at most, utilities would have to do an extra run of their billing.

Of course, on January 1, 2000, there was not a single power outage anywhere in the world, but at least a few dates were written incorrectly.

So, it is my interpretation that the candle holder not only celebrates the new millennium, but also celebrates the millennium bug, and preparing for the predicted mass power failures.
