I'm getting back to this project. Looking at the parts listed online for Alamo/Mott and Ebay as well. My machine looks a lot like the Mott model 88. Maybe it's really a 96? As in 96" long drum; I'll count the stations first and resolve the numbers. I found some likely parts on Flail Master, eyeing up the 5/16" diameter knives (min has a 5/16" through bolt instead of the clevis pin of the Mott). That would make it a fine cut drum. More to figure out, still haven't pulled a clevis and knife assy. A plus? They sell weld on lugs. I am missing one (or both, of one station; need to inspect), that would be convenient. Flail Master has the most thorough (or publicly accessible) web page of parts.
