Wood cracking over time

Any ideas why the wood cracks on the pen wall over time. I have made pens that are over six months old sitting in display boxes and not being used. Some say the wood is drying out, some say gluing technique, some say that during drilling the wood develops small cracks etc. I have experinced this on burls as will as non-burls. Any ideas?

That would be my guess. The blanks were not dry enough prior to turning.

Is where you are storing them a lot dryer and warmer than where they are made. This could be the cause. I've had segmented turnings that were a year old crack when displayed in a gallery because the gallery was considerably dryer than my house.

I make my pens through out the year in my shop so the temperature, humidity very by season. After I make my pens, I put them into individual display boxes and I store the boxes above my workshop, which is a heated area that never goes below 58 degrees. I have also stored them in the house because I thought the temperature was affecting cracking. I take these pens with me to gun shows where I sell them along with my other items (gun and fishing rod racks, game calls, and other turnings). It is very difficult to keep the temperature constant due to changing environments. I use the blanks as received and the only wood that does not crack is any variety of maple (Birdseye, figured, wavy etc). I have looked at the wall thickness and it does not make a difference if the walls are thick or thin.

I wonder if I were to use a moisture meter to control to moisture, but than what moisture content would I use to get the ideal results?
