I'm currently working on a first time DIY project installing 2000 sq/ft of 3/4" x 3-1/2" unfinished Brazillian Cherry throughout my home. I got halfway through the first room (a guest bedroom) and stopped because I have some concerns. I'm noticing that I'm ending up with small gaps between the boards that are nearly impossible to correct as I'm laying them down. This is because the width of some boards do not match up at the ends. They could be off by as much as 1/8th of an inch. After reading through this forum, I've learned that this may be caused by poor milling. That makes sense, but I can't seem to find a good answer for what is considered to be acceptable or not.
The other concern I have is with overwood, which is another thing I learned from reading this forum. I'm noticing that this is occurring quite often, and has spots where it gets to be off by about the thickness of a credit card. Should the flooring be fairly smooth when I run may hands across the boards, or is it common to feel overwood on just about every row? I'm also assuming that this should be eliminated during the sanding process, but I don't know if it's going to make sanding more difficult, and if there is a point at which sanding won''t work.
I know it's hard to see this stuff in photos, but I figured it might still be helpful. Here is a link to some photos:
