Heya Spandit,
Any luck yet, I only just saw this so might be a bit after the fact here.
Cause were you looking for a electrically driven machine? I currently have a Adler 30-1 standing around which is a variation on the very common singer 29k.
and that allows you to do absolutely everything, however doesnt sew very fast. although that for me being in leatherwork is actually a good thing as I have a ton of control.
The beast sews up to 12mm or half an inch of vegtan, and that is purely as the walking foot wont go any higher than that XD.
but for thinner leather and canvas projects you might be better of with a straight sewing machine with an electrical drive.
but just wanted to show you the option did exist. as I have the ability to sew pretty much everything heavy on my machine now.
as long as I keep it under 12 mm. also because of the pivoting direction of the walking foot I can sew in every direction and do some really awkward stuff with my machine as well.
Goodluck on your hunt for the perfect machine Spandit
yours sincerely
Ruud
