Hello,
I'm trying to get started sewing leather, so have been looking for an inexpensive singer 111. I found a pair of machines, a 111w102, and 31-15. The 111 ran well, but has a 3000 rpm motor, with clutch. The 31 has a 1700rpm motor with a separate clutch. Will the 111 work well on the 31's table using the 1700rpm motor? It fits, but I'm not sure if the motor will be strong enough. At the moment, I don't have plans for anything thicker than 1/4 of an inch, so should be able to use the 111, until I outgrow it.
