I let stock blanks air dry, I am slow making a gun that the ones waiting in the wings have plenty of time.
For bow wood I use this; it would hold 2 or 3 stock blanks, it uses natural convection with adjustable vents in the top and bottom.
I have found that I have to let green wood air dry to 16% on the outside first before I put it in the box or it will check. The temperature is adjustable, I have a dimmer switch on the lights, I start out at 90 degrees.
