Actually Kenmore did make a cabinet for the 8 stitch machine....it's the same type of cabinet that's in the pictures. The machine has holes underneath & you bolt it to a shelf in the cabinet. And it would raise & lower into the cabinet I think there were 2 bolts.
I've got an Ultra Stitch 12 but since I always leave it sitting up, I didn't bother to buy the cabinet. I used a traditional sewing machine cabinet....put in a shelf so the machine bed was level with the workspace...then cut a wood insert to fill up the space around it...& finished it to match the cabinet.
