I made motion plates. Tow t1.5 mild steal sheets were soldered and cleaned up and cut as followings.

モーション・プレートを作る。ｔ1.5の軟鋼板を二枚半田で貼り合わせ、周りを綺麗にした後穴を開ける。その後以下のように加工。

Mostly machine cut.

ほぼ全部機械加工。

They were separated and some corners were rounded by files. The temporary soft solder must be completely removed to prevent bad effect on silver soldering.

ハンダを剥がし角にRをつければ本体完成。ハンダは完全に除去しておく。あとで行う銀ロー付けの障害になる。

Mounting brackets were made in the same way.

取付ブラケット部も同様に作る。

Mounting brackets were cut out.

ブラケット切り出し。

Finished brackets.

出来上がったブラケット。

All parts were silver soldered.

銀ロー付け完了。

Brackets were machined down to have exact right angle.

本体に対するブラケット取付部の直角を出すためブラケットを切削。

After checking movement of crosshead and angles, the motion plate was temporarily fixed by parallel cramps. The mounting thread on the frame were made to the work.

クロスヘッド、スライドバーの動きと直角を確認して並行クランプで仮止め。フレームにモーションプレート取り付け穴を現物合わせで開ける。

Motion plates mounted.

モーション・プレート取り付け完了。
