Do they use a NMC grinder instead of steel masters?
If so that's how they are able to offer so many profiles
just load the profile and the nmc grinder does all the work
accurate, fast, no human intervention to amount to anything
Most of you may know that Rick Jones "Controlled Induction" program can generate custom intake and exhaust, opening and closing sides lift files based on your unique requirements and build
back when we were lucky to get a lift table to 3-4 decimal places then rough it out resulting in a series of flats which were then smoothed with file then optics were used to reflect off the flats and the "master" touched up
some people still love these cams- (but they have been remastered for CNC)
Remember when Harvey Crane offered to "Computer smooth" competitors cams
I do not know if anyone took him up on it but it served to advertise his quality
Harold Berkshire used a 8 bit pre PC/ Apple computer to design his cams- much better than the HP35 we used
Then ISKY with his use of the IBM "Mainframe" a big step up in computer power
his Polydine cams with Poly the parrot-
Those using steel masters now can use a cnc grinder to utilize more numerical precision
so newer masters can be better than those done on a mill
