DIY pro series table

Hello I have 2 questions about the pro series table. If I put 2 4’5” tables together, can I put it on wheels? 2nd question is, can I put an H brace under the 2 tables so I can sit at it or is that too far of a length for the H brace? Thank you

Yes you can combine tables with wheels. An H supports will be just fine if you use 2x2 or 1x2. Nothing overbuilt ever broke.
