So I am knee deep into using my, new to me, singer 15-91. It has the direct drive “potted” motor. The 15-90 is almost identical, except it has an external motor connected with a belt.
I have heard people recommend the 91 because it can sew through heavier material, is stronger. And people saying it does just fine for domestic sewing.
Is the 91 better than the 90 at punching threads through thick material (making saddles)? What If one replaced the motor on the 90 with a new, more powerful, motor? Would the power nod go to the 90?
Why I am asking, well, 2 is 1 and 1 is 0, and I am looking for a second 91 or a 90. It would seem an external motor would be easier to keep going by replacing it. The potted motor, I have not seen any new ones available.
Thoughts? Real world experience on the differences in power?
