[QUOTE="SidecarFlip, post: 933056, member: 39764"] KB: I might add that we are not in the casting business unless you consider casting slabs for rolling to be a casting. Our company is in the business of flat rolled high strength alloy sheet. I know the 'ingredients' added to the ladle, aluminum, copper, zinc, OTM such as sheared rail (interesting machine btw, chops the rail into 1 foot lengths) and other ingredients in proportion th achieve a particular melt depending on the ASTM grade dersired. Myself, I'd never coinsider an aluminum framed press for anything other than bullet seating simply because of the inherent flex factor of aluminum, it's not as rigid as cast steel or cast iron, other than that, IMO (strictly) all the cast frame presses are fine so long as the frame is sufficiently robust and designed with strength enhancing ribs and they all are (far as I can ascertain)... Different manufacturers offer different 'unique' designs, some appeal more to one individual than another but the basic structure remains unchanged, a device to loacate the moveable ram and keep that ram in alignment with the boss that engages the die when pressure is applied without deflection. The 'wheel' has already been invented but certainly can be improved upon from the basic time tested design. Same applies to reloading presses. [/QUOTE]
