gottaknow : Thanks man! That is a huge amount of useful information. I very much understand that quality is of upmost importance which is why I'm looking at machines like the Juki. There are PLENTY of threads full of people trying to figure out all sorts of clever ways to use home machines which really ignore the fact that they're not designed to work with leather, which is why I'm here. The fact you guys use 40 machines for a single item is mind boggling!
Wiz : The reason I mention industrial machines is it seams that by going with a home machine you run into issues right away. First you have terrible feed mechanisms, then you have to get aftermarket feet, and then they're underpowered and needles end up breaking. So at the end of the day, you're churning out garbage, with even the best materials and attempt at craftsmanship. I have no illusions or desire of running a commercial enterprise out of this. I have an extensive outsourcing background and recognize unfortunately that such a thing is something that is sent to a third world country for mass production if the designs take hold. So my purpose in looking at industrial machines is simply efficient and high quality production. I have a full time business which commands my attention, so when I'm "doodling" I can't be worrying about all the short falls in a home machine.
So for a straight stitch a Juki 1508NH gets the job done.
Do you have a specific recommendation for zig zag w/ a compound walking foot for my application needs?
The overcast is pretty cool looking. Would an industrial juki or similar work with wallet depth leather? What about auto upholsery? And do they make any with a walking foot?
Is the only appreciable difference from the 1508 to the 1541 the height (ability to work with stacked upholstery... as in leather, foam & vinyle at once)
Thanks again from both of you. Hugely informative answers that you are offering out of the kindness of your hearts and passion of your business.
