I own the Juki Long Arm and while at the Road To California show I ordered a base for ruler work from Moore's based out of California. I don't know if this is the same company and the one advertising the Sew Steady base. The only problem I encountered is the needle plate pulls out and so the base has to be removed when changing the bobbin case. (I'm sorry but I've had shoulder surgery and not used the LA recently and this is from memory.). I would call Moore's directly. They are really helpful and answered my questions. It did take like 6 weeks to get the base. Good luck. The Sew Steady is linked to Moore's.
