today.....was a bad day....i broke an arbor on the old milwalkie today.....milwalkie machine is a old-fashioned horizontal milling machine...with an arm (arbor) just above the moving horizontal table...i loaded the machine with 2-inch blanks (thread-cutting tap blanks)...all was good except for one tap was an 1/8th inch shorter than the others....(which snuck by the quality control man)....i torqued them in place...hit start-button....and BANG>>>>the cutter jumped when it indexed......hence....my broken arbor.....no worries tho.....thanks to the norton....i was able to grind down another......but it took an hour to do so.....the LINE was down for awhile.....buts it running top form ....once again.... thank u norton.....what a wonderful old piece of machinery!!!!
