I bought a Juki 563 and slowed it down with a servo motor, I also bought a new rotary hook,it is supposed to let me use heavy thread. When I asked the retailer what size thread I could use with it this is his answer:
The rotary hook that you bought is for the heavy thread and you can use thread size 69, 92 or even 138. Recommended needle size for these thread are sizes 20, 22 and 24.
I was hoping to get up to: 207 or 277 thread, so my question would be has anyone set up a Juki 563 for heavier thread and could you please tell me the needle to use and the equipment needed.
Any advise would be appreciated!!!! Help!
