yes, but Uwe I (think) are going to be built to different specs

Of course. They should be made to swap with standard harness feet and no additional adjustments to the foot bars. I was referring to the original inline feet that are sold by the CowboySew company.

Oh, yeah --- prob'ly was intended for use with raised plate (holster / stirrup).  Thanks.

I finally got around to making a real-life version of my CAD model inline presser foot.  Coincidentally I also became warden of a like-new Ferdco Super Bull 2000 with a career-ending massive crack in the casting (it fell off a moving cart years ago before ever being put to use.) The machine lets me test parts for proper fit and take pictures. Unfortunately I can't make videos of it sewing.

This version is done in 304 stainless steel. It looks simple but the CNC mill labors for nearly 30 minutes on a single part. Stainless steel is really hard to work with, literally. No mounting screw yet - I'm still deciding between hole and slot. I'll have some for sale in a week or so, after some fine-tuning and polishing. Pricing will be around $70 for just the stainless steel rear foot, or $90ish for the set including the generic front blanket foot. Plain polished steel will be $20 less.

I think a stainless set for me when they are ready no rush no pressure thanks

Ok, Uwe's had me thinking about this, so I figured I'd have a go as it could be a useful addition to my foot collection. I had a spare welting foot that came with some bits with one of my machines (can't remember which one!). As I have two of those feet, and am unlikely to ever use them anyway, I figured I could sacrifice one. I filled in the hollow on the bottom with weld then got stuck in to it on the belt grinder. Took a bit of trial-and-error but I ended up with a working foot. It still needs a bit of smoothing down, and the only problem I can see is being plain steel it will rust. Two possible solutions occurred to me - coat it with Devcon epoxy or Parkerize it (more messing around but probably the best solution).

how about bluing with gun blue or the like

[dikman]

Good idea! I've got some cold bluing solution, I'll give that a try first.

Wizzo, that´s some nasty marks left by those feet?? i would have thought the whole point of these walking feet machines were not to mark up your leather

The marks are entirely inline with the stitch path and could be hammered or rubbed down if necessary. If one doesn't want any serious foot marks, one should use either a Union Lockstitch or Campbell Lockstitch machine with a right toe stepping foot, or a curved needle sole stitcher that has the bottom channel knife removed (e.g. a Junker and Ruh, or Frobana, or a Landis 12 that uses a curved hook and awl).

Our modern compound feed harness machines place a huge amount of spring pressure on the tiny feet in order to hold down tough and thick leather from huge needles and thread. This comes at a price of foot marks.
