I am very new to woodworking, and I'm planning on building a table for my living room, from boards that are roughly 4x7 cm (1,6 x 2,6") and with metal legs.
The table should look like this:
but with more timbers since they are smaller.
I would like to assemble it so it can be fully dismantled (including the tabletop) because it will probably go through multiple house moves in the next few years, and it would be very heavy and cumbersome to move as a single piece.
I thought I would assemble the boards together by using a flat perforated metal bar underneath the tabletop and M8 screws and inserts, but I worry that it won't allow the wood to properly dilate under heat and humidity.
Is there an other way I could assemble the timbers together?
