Not much progress to report . . . still plunking along as time permits. Cal, thanks . . . but still haven't freed the pulley off of the shaft. The set screw has a flat end, and depth measurements don't seem to indicate there's anything else in the threaded hole. Looks like there is a rough depression in the shaft that the set screw bottomed into. The shaft turns freely in the bracket . . . but the pulley and shaft won't separate. May have to resort to Glenn's suggestion and get out the rosebud tip for the acetylene torch. Moved on to cleaning up the VN ram head . . . Also bringing home my latest acquisition of quite old SB Model A. May have an operating "machine shop" one of these days.
