Workshop (6)

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.  In Workshop (3),  I gave the workshop extremities in the form of tools, and, in Workshop (4) and Workshop(5) I gave the workshop right and left hands by adding a Blacksmith vise and frame vise.  In this installment the workshop will receive the first leg.

Here is the leg, a simple but effective front wheel maintenance stand to raise the front wheel off the ground.  Excellent for working on and around the front wheel: adjusting rod brake stirrups, adjusting spoke tension, fixing flats, changing the tire, adjusting cone bearings, etc.  Let's take a closer look at this simple yet ingeniously designed front maintenance stand.

Very simple materials, only uses 3 pieces of rod iron (neck, body and handle), a joiner piece connecting the neck to the body, and, two rubber tubes on the neck fork to protect the bicycle from getting scratched. No screws or nuts, just spot welded in four places.

Here is the neck.
Again, note the rubber tubes on the neck fork to protect the bicycle from getting scratched.

The neck fits in the joint formed between the underside of the down tube and rear of the head tube.

The handle allows the stand to be fitted to the frame with one hand.Img_0031Img_0011_2Img_0025

The wide base provides stability.

Using one hand the stand is inserted between the main frame and fork, with the neck portion fitted under the down tube and behind the head tube.

The stand is pulled forward while simultaneously lifting upwards to raise the front wheel off the ground.

The wide base of the stand, weight of the bicycle and weight distribution shifted to the rear stand all work together to provide a stable condition for working on and around the front wheel.

Changing the angle of the stand raises or lowers the front wheel.
Steep angle raises the wheel well off the ground.

Shallow angle lifts the wheel just off the ground.

These old front wheel maintenance stands are very handy, made of simple materials and construction, easy to use, and, will last a lifetime.
