I would like to build a new workbench
https://mechanicguides.com/best-woodworking-bench/. My current one I got for free on Craigslist and has gotten the job done but lacks a lot. I'm looking into using a solid wooden door as the top. I'm finding several sources for used doors but they are composite cores. They are very heavy and seem very solid but should I hold out for solid wood like oak instead of a composite type?
Thanks
