I think it tapers the end of a dowel.
That has absolutely nothing to do with making Model T spokes. Marc, has it right.
I'm always amazed at the stuff on Ebay that gets labeled as "Model T", almost as if it is an era in time, like "classic" or "antique".
It is called a spoke shave. I think it was used when making tapered ends for buggy spokes and some furniture making.
Marc is correct it is the first tool is used to cut a taper on a round piece of wood. This would be followed by a hollow auger to cut the tenon. The draw back is it cuts a square shoulder at the base of the tenon, creating a weak point
Jerry is also right in that most spoke makers use a duplicating lathe to make the spoke and cut the tenon, leaving a round shoulder at the base of the tenon, making a much stronger tenon.
I think the tool was most commonly used for chair making.
Here is a link to a hollow auger:
Jack - I'm not that "up" on woodworking tools, but I think a spoke shave is similar to a draw knife. I'm only pretty sure of that because my Dad was quite a woodworker and boat-builder, and he used several types of planes as well as draw knife and something he called a spoke shave which as I recall was smaller than what he called a draw knife. Somebody else here will know,......FWIW,.....harold
Harold you are correct. KGB
It's a huge pencil sharpener for turning the ends on chair spindles.
I have always been told they were,I have several sizes of draw Knives These old tools were something else.Made you work harder for sure.
These are spokeshaves. I use them when hand making chamfers. One has a curved sole which enables it to be used on concave curves.
A draw knife is a much larger tool. It has a wide blade with a handle at each end, at right angles to the blade. The user pulls the tool towards himself when using it, hence the name drae knife. Spokeshaves are pushed away, as you would use plane
