This is my first experience with a sawmill so there is a steep learning curve. As reflected by the price, the OS23 is an entry level mill. Assembly instructions are adequate but could use more detail. I had difficulty adjusting the motor (10hp) to run at full rpm. This along with proper blade tracking and sharpness is critical to avoid bogging down and getting the blade stuck resulting in either clutch wear or burning up the belt. The water valve and mounting grommet for the blade line system is poorly designed and leaks from the very beginning. For the price, it is a satisfactory entry level mill and with a little more investment by Frontier or the operator is a serviceable hobbyist/home saw
