Detailed up of shafut and berrings.

262-1

I improved a shaft and a detail drawing of the con rod. The next intends to draw a perpendicular shaft to drive a valve.
(The inside is a guess with the drawings. There is not the conclusive evidence.)
シャフトとコンロッドのディテールを修正しました。
次はバルブを駆動するための垂直シャフトを描きます。
(内側は図面と推測です。決定的な証拠がありません。)

Con-rod and piston

I make a con-rod and piston of Isotta Fraschini V6.
I have just only plan for maintenance.
Unfortunately it is no details and I can not understand materials.
The shape of the upper part of the piston in particular is mysterious.
However, I negotiate to people having it now. I will obtain many documents in this autumn if I go well.
