Workshop (4)

次回この記事の日本語版を投稿します。

As mentioned in Workshop I have moved and I am in the long process of getting settled in.  In Workshop (1) I gave the workshop a heart by restoring on old bicycle shop clock, in  Workshop (2) I gave the workshop a torso by building a workbench, and, in the previous installment, Workshop (3),  I gave the workshop extremities in the form of tools.  In this installment I will give the workshop a right hand.

There she is, the workshop's "right hand", or "right-hand man", an early 1950's Hataya Tool Manufacturing Company vise.  These types of vises go by several different names including:  Blacksmith Vise, Leg Vise and Post Vise.  Let's take a closer at these different names.

A Blacksmith vise, as the name implies, is commonly found in metal shops.  These vises, as opposed to a Machinist vise, have a floating screw box which protects the screw from the heavy pounding that comes with the job of forging metal into various shapes.

Post Vise, as the name implies, requires the vise to be mounted to a vertical brace such as the post of a workbench, as opposed to a Machinist vise which is mounted only to the top of a workbench.

Leg Vise refers to the thick long pole attached to the bottom of the vise which transfers the impact (energy) of hammering to the ground rather than to the screw.

Besides being heavy-duty and virtually indestructible, this vise was designed and manufactured specifically for bicycle repair by the Hataya Tool Manufacturing Company.
(Refer to Workshop (3) for more on Hataya)

Hataya not only produced tools for the Japanese market but also exported their tools.
The illustration below is from an English catalog. 
Note:  "Specifically designed for bicycle repairing."

Note the jaws have been designed with the added convenience of securing small cylindrical parts such as cotter pins, pedal axles, brake rods, etc.

Both top and right side have this added feature.

Top only.

Side only.

Note the large concave portion below the jaws.  This is used to mount the top tube in so that the vise also serves as a bicycle work stand.

This is a Hataya frame clamp that fits into the jaws of any vise.

Conveniently spring loaded.

Can be used to hold the frame horizontally or vertically.

These Blacksmith vises are amazing and will easily outlive their original owners.  "Old" often gets a bad rap; people tend to get caught up in the mass marketing and advertising and in some cases erroneously believe that just because something is "new" is better than "old".   Not always.  In fact in today's disposable society where things are not built-to-last, often "old" is superior to "new" and because "old" is often "used" it is cheaper to boot!

In this instalment we saw the workshop's right hand.  In the next installment we shall take a look at the workshop's left hand.
