My wife and son went to Paris for school spring break so I figured I had some time to work on a bookcase for a friend from work.

Things were going nicely until the blade bound in a cut of a 2" piece of oak - there was no kickback but I heard a "thunk" sound and the blade disappeared.

I quickly shut off the saw and took out the insert to look down inside to see what happened. This is what I found:

As you can see, the two pivoting mounts that hold the motor to the frame of the saw have snapped right off.  Now I know it's not the greatest saw in the world, but it's given me more than my money's worth over its life. Of course it's Sunday and the Delta parts line is not open.  I'll call them tomorrow to find out how much the new trunnion will cost.  Then it's a non-trivial project to replace the trunnion and get the saw tuned and working properly again.

Well, how about a pleasant surprise! I ordered the new trunnion on Monday morning and it was delivered on Wednesday, and it only cost about $34! I also bought new brushes for the motor since I had to take it out anyway. I didn't need them as they only had about 1/16" wear.  I rebuilt the saw around the motor (yes, it works that way) and using Mike's dial caliper, we got the blade aligned to the slot within about 2 thousandths. I'm happy to say it cuts like butter now, with no binding or burning like before.  Better than new!  Here you can see that the design of the casting hasn't changed to beef up the pivot points.
