Result is simple, sturdy and convenient. It does not take much skills or special tools to make it. Pros would probably point out some cosmetical errors or use different construction solutions. For me and my boys these tables work fine.
What you need to do this table.
Skillwise - you should be able to saw straight, drill straight, have enough patience to get your measurements right and that's pretty much it. I am not a cabinetmaker, not even a carpenter, but humble translator. That says all about required skills ;)
Toolwise - I used two different handsaws (big and small teeth), electric jigsaw, electric drill (6 & 10 mm bits) for dowel holes, dowel markers, electric sander (60&100 grit papers, alternatively you need LOTS of patience), electric screwdriver, hammer, square rule, rule, tape-measure, pencil, glue. That's it.
Materials - laminated timber: one pcs of 2500x600x28 (for the tabletop), 3 pcs of 2500x200x18 for racks and edges, some 50x50 for edge supports and legs, some fiberboard for rackbacks (plywood would be better, but I had the fiberboard handy).
All the measurements are in mm. That's a sweet revenge to all you inch-loving anglosaxons for those long hours spent converting your stuff.
