I'm breaking all of the rules with this bench. Except the ones that are important.
I started this bench around the first of the year, and got part of the top glued up. As it got north of maybe 100 pounds, I was having trouble maneuvering it due to some sore muscles and haven't gotten back to it until now. And yes, if you are wondering, I am feeling much better now. Ask me about transdermal magnesium sometime.
Anyway, this bench is destined to be ugly. It isn't going to have the best or prettiest joinery. It has voids from splits and knots. It has screw holes. Most of it isn't going to be beautifully finished. Or really finished at all in the proper sense of the word.
In short, I'm throwing out all of the minor rules in favor of getting a bench done that adheres to the important rules.
It is already heavy. It will be flat. It will be stable. And I will be able to clamp stuff to it. That is what a workbench does. And as a bonus, it wasn't expensive. Read more about Laminated workbench construction
