Making a big one for the build instructions.
How many 4’x8’ carves have you seen?
My stance on carves if you want sharp corners the right way to do that is surface your material, do not move the material, start the carve. This works for 4’x8’ carves as well.
The table is not as important as people keep making it out to be.
Anyone that plans on rolling, folding, or moving their table in any way, they would need to surface the table top every time to be of any effectiveness. For them their only hope is to surface the material to be carved first.
This 100% goes along with the yellow brick road issue. A perfectly perfect table can make things easier, and the need for less material removal when surfacing, but no wood is flat enough not to need to get surfaced first. Think of all the jointers and planers pros use to make a decent table. Flat tables just make things a tiny bit easier, 100% not required.
