There is no conflict between wood species, only in a person's mind. I spent a lot of wonderful time helping people choose wood to match their taste. I guess it's a little late to suggest that you don't stain wood. Embrace pine for what it is. It's beautiful on it's own. The natural blond color is really nice. Don't try to make a silk purse from a sow's ear. If you want dark wood, get walnut. The added cost might just give you joy for the rest of your life. Stains, such as Minwax, will eliminate the natural iridescence found in all wood. The depth, if you will. Pigment stains will "flatten" the wood. No more magic.
All the wood in my Scamp
and the new work in my home is Douglas Fir, carefully selected from piles at the nearest lumber yard, and finished in clear gloss. When I was in the business, I had great sources of wood in Vermont. Now that I'm in Idaho, I use what grows here.
Most of my customers didn't realize that I had carefully grain-matched all their drawer fronts from the same piece of lumber, but I think they're still enjoying the subtle difference today.
So, at the risk of sounding like a wood snob, I say again, don't mix woods. This may be feng shui thing, I'm not sure. But I know that wood can give you harmony in your life, every day. Go ahead and use "golden oak" plywood doors and "bamboo" flooring if you want to. Who really cares? Well, I do, but I'm not saying that everyone should.
I not sure what you mean by a set of blades, but I'm thinking you must have a track saw, in order to get square cuts? I admire your initiative, working on a pallet. When I retired, I sold my machinery, thinking I'd find some other worthy pursuit. Now I've turned a quarter of my double-wide "manufactured" home into a "gentleman's shop". Smaller machines, tight space,....but it's so much fun. When trying to describe this home conversion to a local woman , she said: "Your not married, are you". It was a statement, not a question.
Pictures can say a lot more than words. I intend to upload an entire gallery, as soon as everything is finished, which, of course, it never will be. But here's one:
How did I get here from "toe kick"? I don't know.
