Coupling rods were made. At first two pieces of t3 mild steel plates were soldered together and cleaned.

サイドロッドを作る。まずはt3の軟鋼板を二枚ハンダ付けして外周を綺麗にする。

Holes for the rod pins were made.

ロッドピン穴を開ける。

Holes for shaping were made.

外形整形用の穴も開ける。右下の穴は間違えて開けちゃった奴なので気にしない事。

A handle bar was attached to the work for arc cutting.

ワークにハンドルを取り付け円弧削りを行う。

Arc cutting with roughing end mill was much easier than with normal end mill. With normal end mill I cut in gradually with many paths, but with rougher t6 MS plate could be cut in only one path.

今回はラッファーを使ったのですごく楽。以前のように少しづつ下方に切り込んでいく必要がない。t6の板を一気に切削できる。

After rough cut normal four flute end mill was used to finish.

ラッファーを普通の四枚刃に替えて仕上げをすればロッドエンドの形ができる。

Other end was also cut in the same way.

反対側も同様に切削。
