Tool gloat ,old chainsaw.

[Woodlee]

I was in Darwin on the weekend and went to a local market at Parap.
First time I have ever seen a tool stall there .
Anyway I picked this little gem up for $20.00 bucks .
I reckon this would be as rare as chicken lips and
worth a big quid as a collectors piece .
Any one ever seen one like it or know anything about them?

u sure its not a joke tool? seems a rather inefficient mechanism for cutting timber. the force required to turn the handle and press down on the blade for a bite would not make the tool condusive to long term use I would think. also the leverage you would need to exert on the handle to press the bar down into the timber would make it very uncomfortable.

but hey, what do I know - it may be real...

Good score :2tsup:.

If you put a bigger bar on it, should be good for slabbing, and she'll run on the smell of an oily rag :D:D

It seems like a lot of work to manufacture a joke. And a hand-fired chain saw seems pointless too.

Possibly (and really stretching the imagination), a hand saw with relocatable teeth to reduce need for sharpening.

Good score, no matter what. And you can always fib about its operation.

Any manufacturer's mark? Patent number?

Cheers,

Looks like a home made joke to me. :D

Someone's having a lend I reckon, and its not even April 1. :)

looks like one of those new "SAFETY" chainsaws with the extensive guarding removed for the picture!!!

Yeah , well I though I would engage in a bit of fishing and see how many bites I got .

One bait, six fish. Not bad. Not bad at all.:D

Haha, i think it's marvellous. The guy who made this by hand, from parts of a broken petrol saw and a wooden homemade grip, must have had high hopes to go trough all the trouble. But at every crank turn two or three chain teeth pass through the wood, as opposed to fifty or more teeth during a push with a conventional saw, which is far more efficient. He could have predicted that.

I wonder what would give away the clue first, the tiny sprocket wheel beneath the crank and the crank's mysterious bearing suspension; or the scroll in the grip, seemingly made with a modern router?

Before you start to think i'm the seventh fish, i'd like to present to you the "osteotome", the first apparatus with the chain saw principle, invented in 1830 by the German surgeon Bernard Heine from Würzburg. He invented this saw to minimalise surrounding tissue damage while sawing off bits of bone. This damage would occur while moving an ordinary saw back and forth. The saw itself can remain in a static postition and needs only to be pushed downwards, since the teeth move by themselves. This is handy for tight spaces, like in rib cages that need to be opened to get near the heart, without damaging the lungs.

So, if the prankster with the "first antique handcranked chain saw" would have used a far larger sprocket wheel to increase efficiency, he could have made himself an invention of a saw for crammed corners with minimal damage of the surroundings. This thing could then also act like a plunge circular saw or a electric jig saw, both of which are able to start a cut in the middle of the material instead of somewhere around an edge.

My Dad has a similar thing that he totes out whenever unsuspecting guests arrive. It's a little simpler, it's a piece of 3/8 chain fitted to an old hacksaw.

Reminds me of a similar thing I saw somewhere that utilised an old brace, a corkscrew and dog muzzle to make a dog or cat carrier :D

Looks a bit like this

There is one hanging in the bar at the Garadunga Hotel.

looks cool and i wouldnt have put it past some inventor 100 years ago to have made one or even marketed it. in a book i saw cant remember what one it had lots and lots of old catalogs and stuff from domestic products to an auto log saw that ran very much like a power hacksaw so you never know there have been some very funny tools made

thanks for showing ill show that to my grandfather he will get a kick out of that one :2tsup:
