If you can't sew these seams with a paddle or inline foot, find a shoe repair shop and pay them to sew it on a curved needle sole stitcher. It does need about 1/4 inch of space from the raised sides, just like a shoe might have.

I will look into the sole stitcher option.  I can sew raised leather pieces with a small border but not the swells that have no border.  Here are some practice raised pieces.  I would use a smaller needle and thread for the real item.

Oh yea of little faith, You in the wrong forum section if a you going to use language like that. Sometimes the answer is in the formula. If the swell is made of the right sort of rubber/foam it will sit down under the pressure of the foot and bounce back up as you sew along. There is also another special foot set that may be hard to obtain but it allows you stitch around the welts on shoes. Lots of adjustments with those so I would try the paddle feet first. Could you load any pictures of the bridle pieces?

The swells are two layers of skived leather with a padded liner added for a halter.  The pictures below show a swell being shaped in the rounding block, and a skived strap along with a shaped swell ready for sewing.  The bridle picture shows the hand sewn item.

Too bad you don't have access to a Campbell-Randall Lockstitch machine. They have round reins plate/foot attachments in different widths. I think there might also be attachments for a Union Lockstitch machine. I might have had a set of them with my first ULS, in the early to mid 1990s. The foot resembles a piping foot. The throat plate was raised on the right and had a channel on the left for the round portion. This is from my old memories.

I'm trying to visualize a modern day setup you can fabricate on a Cowboy or Cobra harness stitcher. It would begin with the raised holster plate and the paddle or inline rear foot. The holster plate might need to be trimmed on the left edge. You'd need to create a side jig on the left of the holster plate that holds the round strap in position with just enough side clearance for the feet and needle to pull it along. This jig might slide over the arm, or stand up from the left end of the pedestal.

This is all I've got until the coffee sets in and takes affect.

Just drinkin mine now.....

This is not the best video to show how I do something similar. At about 30 seconds in you can see a bit of how I do it. I think that a cut down blanket foot and and centre foot that is not the open toe type it would be possible if you are game to grind them back. On the blanket foot you have to grind back only enough for it to ride up tight to the swell. Only the part in the middle of that foot at the back will be doing the holding. I did have to grind the needle plate slightly off on the left edge to stop the swell pushing against the feet. https://youtu.be/1xy8efhw1U0

I am starting to toss the idea of making a round reins attachment for my cb4500. I sometimes replace purse straps and leashes and some are round. I do some on my long arm Singer walking foot machine, using a 1/2 or 5/8 inch piping foot set. But, the seam is always lying flat when I sew it. With a proper piping attachment, the round part would be half way up and down as would the seam.

If you do make this style for a Cowboy 4500 and Cobra Class 4, please let me know.

I am thinking about it but what diameter size would be best to start with is the question? 1/2" or 5/8" you mention but would this apply on such a large machine with normal leather point needles and thread? How round are the round reins on average I wonder along with other horse related gear?

I will have to start my own post with this question I guess. Sorry for going off topic to the OP
