at some point i need to make more work surface space

i like the torsion top idea but not enough space for 4x8

i am thinking of making either two 4x4 or two 2x8 torsion tops

i think the 4x4 make more sense as they are useful separately
sometimes i only need 4x4 work space

the question becomes what attachments to use to make it easy
to connect and disconnect to get them out of the way

they will sit on saw horses

any one made or use a torsion top in the shop
