This is a 26″ wide S-480 roughing planer.
Note the tall chip breaker assembly. The chip breaker assembly has more “yield” for ease of feeding irregular thickness lumber at faster feed-speeds.
It is a roughing planer only. These are designed for rough mill operation, not cabinet shops.
It will typically run a 30-40HP motor; this one has 30HP.
It is a four roll machine but has large diameter rolls and cutterhead.
This one is equipped with the “Newman Quiet Cut” helical cutterhead.
It has 6 rows of individual carbide bits in a helical pattern to reduce noise.
Bits are like new in this machine.
Comes with a grinder for sharpening in the head.
The S-480 is a lower production single side machine that Whitney designed originally to go behind a facer.
By “lower production”, I mean it has a maximum feed rate of 120 fpm, as compared to up to 300 fpm on newer models.
This is still a highly productive planer.
It is one of very few single roughing models Whitney ever built.
It was designed to set in line to receive lumber that had been bottom-surface “faced” on either a Whitney S-600 or, more typically, a Porter 715A.
(See my listings of Porter facers)
It competed with the Oliver Strataplane and the Northfield (Shoda) 240 and 360.
