I have my Omega D2 (which is a 4x5 enlarger) on a custom made baseboard. I went to a Home Depot and had them cut a 3/4 inch plywood in roughly half. I glued them together and screwed them together. The part that the post bolts on is, therefore over an inch thick.
You don't really need woodworking skills. You just need some glue and an electric screw driver.
Enlarger this/that size is heavy and it is top heavy. Just make sure your table can handle it safely. Also, being mobile setup, I'd suggest strapping it to the table, so should it tip, they'll stay together.
