Today I begin to build a chain tensioner . This has to fulfill several tasks in this tank , so I can not use commercially available .
Since the tub is very unstable by the two recesses for the plow blade and this was suspended from the old I have to think of something .
So I start first with the eccentrics .
For this I work a 10 x 10mm brass rod in the I install two 5mm and 6mm holes just outside the center.
Since 10mm as the distance between the tub and stator are too big , I milled the eccentric off to one side about 2mm .
So I can now Exenter abschneiten from the bar and the holes and threaded the mount of axes .
And so the eccentric seen later from the side wall.
In order to solder the eccentric stable with a 6mm silver steel axle , I file the holes out square .
So I can solder the parts hard.
Then the eccentric are first processed on the lathe .
The outer loop to form I with the belt sander .
