Hello! First time poster looking for some collaborative woodworking wisdom. I decided to go for the Popular Woodworking 2-day workbench that Chris Schwarz put out. It's been anything but a 2-day workbench so far. For those not familiar, it involves laminating together 2 Ikea 8' x 2' beech counters for the top, with douglas fir for the base. I'm still working on finishing the tops. I would describe these things as anything but flat (it looked so easy in the video...). They're cupped across their widths to varying degrees all the way across. I have the two laminated together, with some gaps here and there that I plan to fill with epoxy. After getting them together, the edges don't line up across the sides and ends. During glue up, one of the tops moved a little bit, so it's a tiny bit cockeyed. Tried as I might, I couldn't get it perfectly lined up, and decided I'd deal with it later before the glue started drying.
I'm looking for help getting these edges squared. Can I run this mammoth through a tablesaw to clean up the edges? Should I do that after flattening the top? I'm a little nervous with this thing on a tablesaw since it's so big and heavy. I plan to do handwork on this bench, so I would like things as squared up as I can get them.
What are some other options to square up the edges? Can I run a jointer plane down what will be the front edge to get it flat? I'm fairly new to handplanes but will give it a shot if it's possible.
If photos will help, let me know and I'll snap some pics. And thanks in advance.
