COWBOY CB 4500/441 Stitch length increment fix

@1hpThat is a nice neat looking job and looks a lot better than my effort. Worth the exercise either way though. I think from memory for every 3mm extra in height you move the knob one click to keep the same stitch length.

thanks for coming up with this great mod! may put some reference marks on the visible side some day.

@RockyAussie I am one of the people that benefits from the sharing of your modification.

I used a square file and some elbow grease to create the additional grooves. The ball detent can be a booger to refit and sticky grease and a knife helped to reinstall it.

When I was refitting the plastic ball onto the threaded rod it split and not having the same size ball I came up with what I had in my collection. An adapter was fabricated using a bolt that screwed into the ball. The added mass has the advantage that the lever will drop down if not held in place so no forgetting to return the lever after back stitching. The length of the adapter is sufficient in length and I tapped it deep enough to pinch the "C" shape when tightened down so it doubles as a locknut.

Good looking end result there @CdK every little bit helps. Magnet attached screw driver rack I assume?

It seems to me that your idea of drilling/countersinking holes along the travel path of the detent ball would be easier than cutting grooves? I can't think of any downside to doing it that way.

Tried that but the cat kept knocking it off, 3M double sided tape now anchors it in place. I do use coin magnets to hold other bits close at hand as I cut down the pedestal to minimums to save space in my work space. The maximum foot print of my machines are determined by the heavy metal base and nothing more, must be the Dutch DNA in me, use as little floor space as necessary.
