I mass-produced coupler by white metal using moulds for Eric.
カプラ本体はElic用に型を作ってあるのでホワイトメタルで量産した。
I thought the coupler might need some sideway movement to clear curves. So I made coupler bars from 3X3mm brass rods.
カーブ通過を考えて、カプラーは首振り式とした。3mmの真鍮角線でカプラー棒を作る。
The bars were attached with return spring made from 0.4mm phosphor bronze.
0.4mm燐青銅板で作った復元スプリングをハンダ付け。
This case I intended to make the pin-link couplers functional. That means pins were required. Obviously the pins to be connected to the coupler bodies by chains and the pins need to have a ring on their top. It was a hard to devise how to make the rings. I decided to cut out the rings from solid brass. I made a shape tool as this.
