Boiled for around 7 hrs. today,my arms are aching big time! Made a drum of dark then lightened up to med. w/wonderful flavor,a couple drums of that.Big time bummer around 4:30 this afternoon, the big 80 cfm Westfalia vac. pump blew a vane or something, sounded nasty. Had to rig up an old wimpy pump to keep the sap coming in,3000 taps on the releaser.Should be able to get parts by late morning tomorrow,we almost all got herias getting the pump head up onto a makeshift workbench. Don't know how much we'll have to boil tomorrow,the farmer I work for was heading out to gather tonight.Looks like a busy weekend!
