次回この記事の日本語版を投稿します。

In the first six posts, Sprung Leather Bicycle Saddles (Part 1), (Part 2)(Part 3)(Part 4), (Part 5) and (Part 6) we took a look at various leather saddle styles from the 1950's: (800 series)(750 series), (900 series)(500 series), (600 series) and (1300 series) respectively.  And, in the previous two posts (Part 7) and (Part 8) we looked at tools used to maintain sprung leather saddles, specifically the "hammock saddle stretcher" and the "saddle spring spreader".

In this installment we shall take a look at a tool called the "saddle box end wrench".

When setting out to restore a saddle, even if the leather and rivets are all in good shape, chances are that the saddle hardware will be rusted and need to be cleaned up, in worst case replaced.  The easiest way to get rid of rust is to disassemble and tackle each part one-by-one.  And when it comes to disassembling a saddle, the "saddle box end wrench" is a good tool to have in one's restoration arsenal.

It is used to loosen/tighten the nuts which hold the springs to the saddle.

One end is for 10㎜ nuts and the other end is for 12mm nuts.

The tool is thin and angled appropriately to enable it to easily fit between the narrow spring coils.Img_2509
