In general terms, are the internals of the Format 4 machines essentially 900-series internals, or are they another level higher in terms of motors, trunions, etc¡?
Yes, in general that¡¯s true, but it depends a lot on the specific machine. ? Certainly in the sliding-table shapers, the Format-4 versions are souped-up 900-series machines. ? Felder might quibble that it¡¯s the other way around, but the guts are the same. ?
