I really like this machine because (like only some machines) when you turn the flywheel by hand it feels completely free as if there is no friction; this makes any machine much nicer to operate.
The "two Speed" motor is a mystery; there seems to be no difference between either setting so I'll have to contact the expert on that.
It goes merrily thru an 1/8th in of softer leather perfectly.
Remember: although domestic machines can sew leather, leathers vary so much due to tanning and finishing that no one rule applies for all. Very detailed and exact practice parts are required for good results on the final pieces.

Damn this is a nice machine to use! Smooth, quiet, strong, Sometimes just find something to do with it.
