Agree ^^^^^^^^^^^
Position of the i beam and the support location is important. The adjustments are done the vehicle. That way the bend point is the axle section after the spring purch. Some say heating the axle is required.........the manual specifically says DO NOT HEAT THE AXLE.
There is a little art to bending the axle as there is spring back. Better to sneak up on the desired spec than over shooting the desired spec. Bending down is a lot easier than bending up. Having the frame level and using your eye or carpenters level can help in watching or judging the movement. I use a old school magnetic spindle camber gauge that is likely 50 years old.

I friend here locally worked a truck straight axle manufacturer ( now closed). All "tuning" of the new axles were done cold is a huge press. These were large dump truck straight axles.
