I want to replace my shop workbench with a custom cut piece of wood.
I work on computers, so it needs to have a surface that is reasonably resilient, but won't scratch computer cases if I lie them on their side and move them.
What type of wood do I need? Is it a veneered wood? Would a plywood with veneer work? If so, how thick should it be?
Thanks
Are you attaching this new piece of wood to an existing frame/cabinet or are you building new?
There are a couple things you could do here for the top.
1. A standard laminate counter top. Check a local countertop manufacturer. Just think how durable your kitchen counters are. The one we work with the most often sells factory seconds on Fridays for a tiny fraction of the cost of a new top. They'd probably cut it down for you for a small fee.
2. Plywood with veneer. This would be a little more work, but could look better if that matters to you. If it were me I'd go with 11-ply. Oak veneer should be the cheapest. You could either edge-band it or nail and glue a piece of 3/4" trim around the edges. You'd also need to sand, stain, and varnish everything.
3. A piece of melamine cut to size would probably be a good trade off between durability, looks, and cost. You wouldn't need to finish it, except to add stained 3/4" trim around the face of it. This shouldn't scratch any components but it's not the most durable stuff.
Anything 3/4" thick should work just fine. That's how thick your laminate countertops are. If you need more strength bond a sheet of 7-ply plywood to the bottom with either wood glue or PL400. It will be very sturdy but also very heavy.
