Hello - just joined this forum. I saw the Juki 1541 postings and know I'm late to the party but I may be able to help.
I'm not a machine mechanic like Greg from Keystone but I have 25 years sewing on walking foot machines and now
train and consult sign and printing shops on how to sew on walking foot machines. The Juki 1541 is great for banners in addition
to leather and it's the machine I recommend first. I have a training dvd I produced on using the 1541 - it's not designed specifically for leather
but there's not a great deal of difference in sewing leather and vinyls. It covers all the basics of threading, inserting and winding bobbins, and all that good
stuff. We use larger stitches and more presser foot pressure for banners
because we're usually trying to maximize feed in pulling big banners through the machine. Obviously at some point you can start leaving "tracks" or marks on the material
and then you have to back off the top pressure. Let me know if I can help.
good luck,
Terry Sheban
