im thinking of building a small, simple apparatus for drying out bowstaves rather than waiting two years... this way i can go select tree limbs of a variety of hardwoods for making my bows...
wood drying kilns generate something around 150-180 degrees of heat... too much and its just a charcoal machine
my idea was to take something like a 7 foot length of tube steel of adequate diameter with an inexpensive heating element running the length of it, a strip of steel mesh could be cut and places inside for the stave to sit on so its not in contact with the element.. and a simple electric themostat can be used to regulate heat... open up one end, slide a stave in, close it, and dehydrate it for a few days
another option would be to lay the tube upright... and inside the cap you could install an electric stove burner element to generate the heat
to make this work, youd need some means for removing the humidity and moisture that evaporates from the log itself... and what size pipe would be neccessary?
