Honestly, I had forgotten that the table has a leaf in the back. When I use this machine I don't really put that back leaf up. I have plenty of room for my projects. I am so grateful to Henry for reminding me about this feature. Next big quilt I make I will use this machine. What a big workspace!
The end leaf simply lifts up and is stablilized with a brace. To drop the leaf the brace lifts up a bit and slides under the table.
The back leaf lifts up and slides on metal rods until the bracket is in position.
