Hi, I am looking to buy an industrial walking foot sewing machine for sewing leather bags and have a question.
Some of the machines I have looked at from Craigslist don't seem to have the knob (or slider) with which one usually use to regulate the stitch length.
*I tested one machine that did not have the knob but you could still regulate the stitch length by pressing down a button on the machine bed and then turning the hand wheel a certain way....the button was hard for me to push down and I could never get the thing to work...so..
My question is: "If I DON'T see a knob or slider, can I assume that the machine way of adjusting the stitch length is the method that I described above*? i.e.. Could there be a dial or slider located elsewhere on the machine (not visible from a frontal shot) that would function similarly as a knob or slider that is normally in the front? What I am trying to say is that I would *not* want to buy a machine if it doesn't have an easy and straightforward way to adjust the stitch length, and by that I mean, just turn the knob left or right. (Or slide the slider up or down.)
I've attached a pic of a Juki LU-562, which does NOT seem to have the knob or slider:
And here's a Singer 331k104 which DOES have the knob.
Thanks for any knowledge anyone can give.
