i recently bought an antique "Free" treadle machine...i ordered the belt from "lehmans" for less than 8.00 and that already had the pin ready. also, for cleaning the machine use wd-40 everywhere..especially the bearings underneath the machine. then wipe everything down real good and oil the places indicated for oil. after cleaning the machine and the cabinet i gave all a good waxing and buffing with beeswax.
