Connecting 2 54”x54” diy pro series tables

Hello, has anyone connected 2 of the 54”x54” pro series tables together yet. Just wondering what your frame looks like underneath or any advice on doing that would be great! Thank you

The process is the same as this video. https://youtu.be/i1kS72AeRUs?si=76wH3zXbADyt2S-_

I’d replace the 1x2 with 1x3.

Use these brackets

Add 2 center legs to help with stability

Ok I just ordered the tables a couple days ago so I’ll to order a set.
Thanks Jason
