Besides short arm space threading is a hassle since you have to move the machine to the end of the frame.
Bobbin replacing is a big hassle also. These machines are not made for a lomg arm frame.
Mine was set up by a profressional and I have a stitch regulator and a lazer light on mine.
My rods are big around also so even less space. I havent used it in over a year.
I have the Baby Lock Jane and what a hassle to thread and hate the under the machine bobbin case.
