Mechanism for adjusting crank radius 1b

Input: pink eccentric shaft.

Output: blue slider linearly reciprocating.

Yellow eccentric bush is idly mounted on the eccentric of the pink shaft. Turn the yellow bush to get various angular positions in relation with the pink shaft, corresponding various stroke lengths of the output.

The grey gear disk and violet nut are for fixing the yellow bush and the pink crank together after adjustment.

Stroke position can be adjusted thanks to screw and round nut of the green conrod. The video shows the process to reduce stroke length from max value to shorter one.
