Can someone identify this wood?

I don't think it's either.

Likely Birch, could be (soft?) maple, and possibly poplar/tulip.

Certainly not oak.

Ding! on the Birch. (Where was my brain?) I think you're right about that, but it doesn't look like Poplar to me. That door looks like Birch ply.

The poplar thing I mentioned is because I have seen poplar do some birchy things, in grain and color. Not likely that it is poplar.

True. Poplar can be the cameleon of woods, depending on from where and how it's cut. I never can seem to get a piece without a runny nose. :-)

I use a lot of poplar. It machines beautifully, paints beautifully in the pigment of your imagination and is dimensionally very stable and cheap. Never had any nose issues with it, unlike teak and such. Padauk messes with my eyes. One of my guys' hands turn purple when he touches/sands oak.

Weird about the purple. I second everything you said about Poplar.

The runny nose thing... I was referring to the green streaks.

I only get purple hand from mahogany. I'd have that guy's body chemistry checked - it's fooked up.

Okay, I'm back, and found this - it does seem to be a function of body chemistry.

It doesn't look like oak to me.

Thanks. I'm missing a small cabinet door, and I want try to make a replacement. The cabinets are mid 1950's vintage, very plain but decent quality.

I 'third' the ID as birch. I'll go further and say 'birch with a pecan finish'.

Can you tell if that door is plywood. I can't see enough detail on the edges to tell for sure.

If it's simply a piece of plywood with beveled (or curved) edge, you're is good shape. You can use the cut-offs of plywood to play around with the finish until you get it just right.

Might also give you a good excuse to take all the doors off, give them a chemical stripper bath, and refinish all of them. Well... then you might as well do the face frames. :-)

oops, sorry.

Thanks for the added information. If the replacement door works out, I may try to refinish the existing doors.

I get that too. I think it's the tannin in the wood that causes it.

I'm almost certain that the doors are cabinet grade plywood with two cabinet grade sides. The doors are flat and plain with only a beveled edge. Looking at the edges, I can see the thin veneer layer.

I'm new to woodworking, so even this simple project is big to me. Especially refinishing all the doors.

But I'm more than willing to try to learn a new skill to save the money of replacing them.
