I have been building off my bar top using sheet rock or a ceiling tile to work off of. I`ve been in the hobby about 9 months and have been thinking of building a cheap worktable .
My wife works in the housing trades, and I picked up a couple of cabinets that had some light damage for free . Then I found a Oak slab 30 x80 for the top . it`s much stronger than a hollow core door. Got it at Menards for $1.00
I just started screwing the cabinets together and a will build a hardwood frame for the top to set on , as the cabinets are not the same height. Found a bunch of maple in the dumpster at a job site. So far I have $1.00 invested and will post pic`s of my progress .
