The staining was the least enjoyable part of the build. I tried to take the easy way out (I thought) and use a product that was stain and poly combined. The combo stuff was hard for me to keep a consistant thickness so, the color looked terrible. Luckily I had only stained the inside parts so, I sanded the parts back down to bare wood (only on the parts where it would be seen).
Knievel mentioned in his Woody thread that maple was hard to stain dark. I wish I had read that post better because he was absolutely right. After doing some research, I found out that hard woods do not take (dark) pigmented stains well because they do not soak into to the wood. When you apply the stain it just sits on the top and then when you wipe off the excess, most of it comes off.
Most of the home improvement stores carry the pigment type of stain. There is another kind of stain that is actually a dye and it is easier to stain hardwood to a dark color. I ordered dye from Rockler.com. So, once I had the sanding done, I colored the wood with the dye and then I put on 3-5 coats of poly.
The picture below shows the two different colors. The really dark color on the top is the combo stuff, the color on the bottom is the dye and poly.

Here are all the pieces stained, sitting in the garage for a week, to let the poly cure.
