4" PEC double square, crappy lead pencil (wish I could find a better one), veritas marking knife (huge upgrade over the xacto knife I had been using before).
I also really like my brass mallet...out of all the times I've "wasted" a couple extra bucks for the more expensive version of something, I regret this one the least. Has lots of mass, makes it easy to choke up on it and tap things softly, or move down and whack something to death.
My two favorites were inherited from my late FiL, a machinist. 6" Starret combo square, and an 18" steel rule marked on 4 edges, 8ths, 16ths, 32nds, and 64ths.
Followed closely by a pair of drug store reading glasses.
I'm reasonably certain that everything Minwax sells is a pigment stain, not dye. At least, I've never opened a can of their product that wasn't full of particles that needed a vigorous mixing before application.
I think your table turned out nicely and some of the suggestions made are eye of the beholder. Not saying I disagree with any of them, just if you're happy with the outcome and like the way it looks, if the form fits the function, then the particulars are just less important.
I do have to agree with the learning traditional M&T comment, so much so that I currently don't have any intention of buying a domino. I've done trad. M&T as long as I've been woodworking. They just come natural to me. I don't have a production shop and don't need the speed advantage that a domino would give me. I've gotten good enough at making mine pretty precise and actually think they're pretty easy. Probably not as easy as a domino but I'm fine with that because it's what I've always done.
But back to your table - I think it's really nice. Should become an heirloom.
