I bought my table for my oversized machine back when they did not make tables for them. Only one called Bertha was made and boy was it a problem to put togather and cost over $500.
Now you can even get a Sew Ez table that fits.
Bertha is a big table with a back section that I dont even have room to use so it just hangs down. It is 7 feet long with both the extensions up. It also has a lift.
