Hi Folks,
As most of you know, I am over the legal driving age in Wisconsin. Only rarely do I get my ID checked at cigarette counters, bars or all of the strip joints up here in the northwoods. :rolleyes: :)
Being the dunce that I am, I sent all of my "good" blades out for sharpening at the same time. However, since I was cutting some plywood and retained a decent plywood blade, I wasn't too concerned. For clarification, this involves a table saw (PM 66). The plywood cut with no problem.
Part of my project involved slicing some 2x4 stock in half so I grabbed an old Delta blade off the wall. It was a steel blade with a lot (~100) teeth with a slight rake so I don't think that it was a plywood blade. It may have been called a planer blade. Anyway, I sliced the first 12" long 2x4 with no problem. The second piece was one of those "tough" ones. That is not unusual. However, about 4" into the cut, I heard some rather unnerving sounds from the wood. That was followed by smoke and a STRONG tendency for a kickback. Fortunately, I was able to back the piece off. Remember, it was only 12" long. As I ducked and hit the off switch, I could see a severe "wobble" in the blade. I could also "hear" the wobble because the blade nicked the table insert, both front and back. The insert width is 3/8" so I would guess that the TIR on the blade reached close to 1/2"!!
My first thought was that the blade had come loose from the shaft or that a bearing on the saw had "melted". Neither was the case and when I removed the blade it was not bent in any manner.
Any thoughts?
Ben Franklin once said that, "GOD invented beer so that people could be happy." Now that I have listened to Ben, I can talk about this without shaking. :( :( :)
Whatever, please answer quickly. I am running out of glycerine pills and aspirin. ;) :)
