I have a Delta Contractors Saw.
When I crank the handle to raise and lower the blade in normal operation, there is no problem. But when I want to make Dados, the height adjustment is critical and the blade changes height all by itself regardless of how hard I tighten up the knob.
If I remove the blade insert and look down there (with power cord unplugged) I could see a nut on the backside of the height adjustment.
This nut is on the threaded part that makes contact with the worm gear. While cranking the height adjustment knob, the nut stays put MOST of the time. But then at a certain point, the nut starts spinning and in effect loosens the height adjustment nut.
If you own the contractors saw, you know exactly what I am talking about.
I'm sure there is a quick fix for this problem, so what am I overlooking?
Thanks in advance
