I made the top it’s 16 foot long and made of 24 2x4s. I can not even lift one side but do you think i made it too big? I plan to move it around using car jacks. Is this an unheard of size? Is it insane? I just want a really sturdy long work bench. I really don’t want to cut it in half and make two 8 foot workbench’s #diy
