Ssshhhh (Volume up!) Bernina KL-117 treadling

Treadling my Bernina KL-117 through 2, 4 and 8 layers of Denim. No big deal for her, could also have been 10 or 12 layers. Sewing 8 layers of Denim doesn't even require a special needle: there is a standard size NM80/12 needle used.
The friction drive of the electric motor is disabled by the white cord, leather rim for treadling is set up. The first few Years I had this machine, I used her almost every time electric. But since a Year or two, I more and more prefer to sew my things with muscle power.
In Zig-zag the transition from 4 to 8 layers has a bit uneven stitch length on the under side, and the thread tension in 8 layers zig-zag is a bit too strong in general, but (this is standard thread tension) I'm content how she sews.
This beautiful old Lady will turn 74 this Year and as it is to see (and hear) she is far away from the end of her lifetime. So useful, so reliable, so smooth.
The question is not how long this machines live, the question is how long we can accompany them through their life.
I hope, we'll have some decades in front of us.

Меховое колесо большое и тяжелое за счёт чего машинка шьёт отлично

I have trouble with my 117's motor wobbling around. Is that why you have strapped your one?

[@SH1974]

No, the motor and its guide pins to hold the position are working well, but there is no mechanism to dis-clutch its friction drive to the hand wheel, for treadling the machine. That's why I use a cord to pull the motor to the machine body - against the force of the the leaf-spring that pushes the motor's hard rubber wheel to the hand wheel. P.s. did You check the guiding pins that holding the motor. If a worm screw (that holds the pin in position) is loose and the pin is loose, the motor can wobble.

how you adjust the motor to the whell

[@SH1974]

The support pins that hold the motor case on the machine's body side plate are adjustable horizontally (there are some worm screws holding them in place) and the friction wheel on the motor axis can be adjusted vertically. But here the motor is disabled anyway: the white cord pulls against the leaf spring which normally pushes the motor's friction wheel to the hand wheel.
