I have a home that was built in the 40's. The floors need refinishing since the previous owner moved a door opening and closet, left the previously unfinished floor area unfinished and put in with carpeting. I have since removed the 40 year old carpet. The problem, or at least I think it's a problem, there are gaps between the boards. Some 1/8th inch wide for a distance of several feet. Gradually closing to knife edge. The tongue is never fully exposed and the floor is solid. Is this just natural shrinkage and nothing to be concerned about? And all I have to do is the usual sand and refinish or do I have a real problem?

It sounds to me like your floors are a fine candidate for refinishing. Depending on the look you are trying to achiece, a sand and refinish could be great. If you want a mirror smooth floor with no cracks or seams showing, than you will want to putty the floot prior to sanding, and then do anther touch up putty, then the final sand and finish.
Homes and floors will move before they find their final resting place, and since your home was built in the 40's I think most of the movement will have already happened, unless we are looking at a sinking footing or something that is still on the move. The bottom line is that I do not think that you have a bigger problem than the cracks and seams that you already see in your floor. Good luck!
