modify the sewing machine

I think the hook would need to be of the end like the machine here. Landis have something similar I believe.This works great for sidewall stitching but I'm not sure about through a hard thick sole.

I've never seen a machine with a bed/arm like that, interesting for sure.

They are the latest new craze in the Asian shoe making trade. The answer to the McKays with their limited availability, hugeness and heavy weight. I have seen these machines online, with a few different name badges, but not in person. I think it would be interesting to get more details about them.

What a fascinating machine, Rocky. I gather that the arm can be rotated (about 160 degrees or so)?

Watching that video that Wiz posted reminds me of the old American adage - there's no replacement for cubic inches!! That machine is a brute, going through that thick sole like it was paper (and with thread resembling small rope!!). Even if the OP could modify a suitable machine by fitting the "horn" (mission impossible, I reckon) it would probably lack the brute force required to punch through sole leather and would still be limited in thread/needle size.

It's not something I would even consider.

Hi Giorgi,

To form a lock stitch, a very precise relationship must be maintained between the needle and the shuttle and I can't think of a way to have a rotating horn that contains a bobbin shuttle that doesn't rotate. Even if you could, the shuttle, on either a vertical or horizontal axis, would have to stay on one side of the needle so you'd have that mass preventing you from sewing close to most of the upper and the edge of the sole.

I hate to say that something is not possible but what think I understand you are asking for is, at least, very nearly impossible.
