So I started assembling my drill press (DP1550) last night. In the manual, it says to use a straightedge to ensure that the outer pulleys are aligned to each other. When I lay the straightedge across the two pulleys, only the edge of each pulley touches it. The straightedge does not lie flat across the entire surface of the two pulleys. The motor would need to be lowered about 1/2" in order to accomplish this, but the motor is already at the lowest point in the mounting bracket. Is this acceptable?
