All, I need some help identifying a sewing machine, preferably, a walking foot cylinder machine. The machine will mainly be used to see patches on hats but, I would like the option to start sewing dog harness. I believe 2 12/13oz leather pieces. I was looking into the cobra 26 but I’m not sure if it’ll sew through 2 12/13 oz leather. Any help will be appreciated

I’m trying to swap the needle system on my juki 1508nh to the 135x17 needle system. Could someone please provide me with some directions? Many thanks in advance
