How Do I Prevent Walking Foot Tracks?

[Wizcrafts]

Our harness feet are too narrow and the force of the spring pushes them into the surface. Someone with a metal working shop might be able to cut a new outer presser foot that is wider on the left, to spread the pressure over a wider swath. I think that 1/4 inch width for the left toe, with a smoothed radius, might do the trick. Also, it would help to have steel behind the inside foot, as is the case with all normal walking foot sets. Another 3/16 to 1/4 inch of steel behind the inner foot would assist with holding down the leather.

I just did my cobra feet and now no marks at all. box sealing tape over the hook hole and oil holes near by then dykem btm of feet lower them down with very light pres on to fine sand paper give a light pull then give a look, you know the rest.

I use my saddler hammer and sponge of water, you have to do it right away before the the marks fixate. You got to close the seam anyway.

Its basic mathematic; pressure divided at square millimeters; a bigger foot needs more pressure to hold the work. You could try to reduce the foot pressure a bit, reduce it until it starts skipping stitches and find the minimum pressure needed to avoid stitch problems.

You can also help holding your work piece steady as the thread loop is made, then you do not need much foot pressure at all. I used that technique with my old bottom feed jump foot Adler cl. 5. I managed to reduce the markings from the feed dog to a minimum.

Now I use a 441 with smooth harness foot and feed dog. It do not make any marks on the top side, only a small punch out mark from the needle on the backside.

Reduce your foot pressure, it should allow sewing with a minimum of pressure otherwise your timing might be off.

Good luck
