RE: BASE TANGENT LENGTH OF DOUBLE HELICAL GEAR

Make sure you account for any profile modifications, backlash, etc used in the gear. Some high-performance DH gears have different profile tolerance limits for the drive and coast side tooth faces, which you would need to take into account. With a 199T gear it would also be a good idea to take several measurements around the gear circumference.
