Yesterday my neighbor and I were getting ready to Joint some maple for his face frame, when I turned on the jointer, I noticed quite a bit of vibration, but I figured, the belt had been sitting for a while and probably just needed to be ran and formed.
I had spent a few weeks rehabbing this old jointer that I got on CL for $80. It was in good condition, came with the excessively large floor stand, I put some new blades in it, cleaned the top surface to a nice shine, removed all the gunk, aligned the motor and blade pulley to make sure the were coplaner and leveled the infeed and outfeed table.
I had used it last about a month ago for my workbench project, jointing some Doug Fir, and it worked like a champ, barely any vibration, sharp and smooth operation, just a blast to work with.
Yesterday, was different, perhaps my novice experience with V drive power tools, I figured that the belt had just held its shape and was causing some excess vibration that would work itself out through running.
Well turns out, the vibration go so bad it split the blade arbor pulley down the middle while running. Parts went flying!! That is the 2nd time parts have flown from this thing… (1st time was a loose blade SCARY).
Needless to say, we were done since we needed to joint and face plane the Maple for his face frame. I ordered the part from Sears. I am blown away that Sears still stocks parts for a 31 year old tool.
I will be investing in a power link vtwist belt as well.
