I have my Bernina Activa on the table. I just use the table for piecing, sewing blocks and making items like potholders, table runners, etc. I did use my walking foot with my machine and didn't have any issues.
I am not sure how much your Juki weighs or what it looks like. You can probably go online to www.harriethargrave.com and contact her directly. I am happy with her recommendation.
If she responds to you let me know what she says!
