Drone Drying Brushes
Drone cracking is caused when moisture left in the bores causes the inside of the drone to expand while the drier outside does not. The differential cracks the wood starting on the outside. If the bores of your pipes are getting wet — whether you use a moisture control system or not — you should have a set of cotton drone brushes to dry them out. These five cotton brushes are sized so that every bore size is taken care of.
