Bicycle Assembly ②

次回この記事の日本語版を投稿します。

In the previous post Bicycle Assembly①, it was noted that in Japan retailers were actually extended factory processes since bicycles were shipped as "kits", and, "final assembly" and "final inspection" were both performed at the retailer.  To setforth standards and ensure quality, retailers had to be qualified in assembly and inspection in order to sell completed bicycles bearing the coveted JIS mark.  At the time, the JIS mark was the only assurance a customer had, other than word of mouth, regarding the quality of a product.

In preparation for introducing JIS, and, to better prepare retailers for assembly and inspection tests, manufacturers produced booklets to explain why JIS is essential, and why retailers need to be qualified in order to sell their product bearing the JIS mark.

Here is an example of a booklet from Hikari.

Most of the tools are easily recognizable, but there are a few that you won't find at your local modern day bicycle shop.  Let's take a look.

Wheel Truing Stand
You will find one of these are your local bicycle store, but certainly not this heavy-duty.
Like old bicycles from the 1950s, old tools were also built-to-last.
