I have a JD2 Notchmaster. Only thing I don't like about it, is you cannot cut shallow angles.
I have to use my mill a lot for those situation. Are you using the HF notcher?
Do you use a bending program like "BendTech"? I use "SolidWorks to get the actual measurements then go to my BendTech program. Lot faster than the doing all the calculations.
Sorry about all the questions but not many people here do any bending.
