Thanks for the pointer to glazier's points. I hadn't heard of those and they look like a decent solution.
Thanks for the picture - another idea to consider. I don't have my glass yet. If I get it from a glass shop, I should be able to get a perfect fit, but we'll see.
Thanks for the nice comments! I'm definitely pleased how it came out, given that it was my first real piece of furniture (all previous stuff was shop furniture). And it did check all the boxes of why I built it.
I do have the woodworking bug though, because literally within a few minutes of finishing it, I was thinking "hmm - I wonder what I should do for my next project". Aside from the display case, I also have several techniques I want to learn. M&T is one, but I also want to try my hand at box joints (after I build a jig) and eventually dovetail joints. Having said that, I do enjoy using the Domino.
Padauk and maple has stunning contrast. I have a padauk and birdseye maple magazine rack that looks beautiful.
But Paul is right...it WILL turn brownish gray on you eventually and there's nothing you can do to stop it. My magazine rack has been in a bathroom without windows for about five years now and it's slowly turning brown but still looks good. If it's in direct sun you can expect the color shift much sooner. Either way, it WILL change. If someone tells you otherwise, ignore them...because they're wrong.
I think mixing three species in any project is almost always a bad idea. Walnut and padauk are too close IMO, especially when the padauk starts to turn brown. Go walnut/maple or padauk/maple...all three is a mess.
The can had been in the basement, but for 25 years. I took it outside to open, but it wasn't out there but a few minutes. I wonder if after a couple of decades the shellac, which is after all organic material, had just decayed.
The domino is a great tool. I'm still pretty fresh with mine but have used the crap out of it.
What someone said about putting it away was great advice. The problem I see is in never actually learning to cut m&t joint either by machine or hands or both sounds crippling. You need a 3" deep mortise, sorry, your 500 won't do that. Have a mortise you need to cut right next to a lip or another piece, can't do it. Learn the basic joint so it never scares you off from something that otherwise could be awesome.
