wow, i've never seen a tool like this,
except maybe far away my mom's sewing machine !
it seems to belong in every maker-space nowadays , as it may be outfittet to sew tough & sturdy materials as well !
This device has great potential for an open source hardware project.
Hi,
I could do a step by step tutorial of how its made when I get some spare time, it really is a versatile machine, I have cut up to an inch thick timber with it and metals like brass too, and the good thing is its foot powered and can be used anywhere.
