回転モノで精度が必要なのでレーザー加工機大活躍でした。
シロッコファンは密閉度が物を言うので、ホットボンドで隙間を埋めまくったら多少風量は上がりましたとさ。

My laser processor was of great use, since precision was necessary for a rotating object. Since airtightness is key for a sirocco fan, the air flow rose somewhat once I'd repeatedly filled various cracks and crevices with hot bond.
