After looking at the manual, I see where the tilt lock just locks the forward trunion on the tilt mechanism. The shaft for the elevation doesn't lock.
Must have done too good a job lubricating. Maybe there is a way you can make something to prevent the elevating wheel from rotating once it is set for the correct cut height. Some kind of clamp with a thumb knob you loosen to raise the blade then tighten to hold that wheel from turning.

That is a terrible design flaw. Surely there is someway to fabricate a locking mechanism.

It will take a little thinking ,because you have to allow the blade elevation shaft and wheel to move when the blade is rotated on an angle to cut a bevel.

Maybe an arm with a hole in one end cut for a clamping collar, and a slot in the handle to slide on a stud with a thumb nut to loosen and tighten down to hold in position.

Jim if your getting vibration you might want to check your blades to see if you have any carbide teeth missing. I have the same
dato blades and I noticed yesterday that I have 3 carbide teeth missing on one blade.

This is obviously a dangerously unsafe situation. (Yes, I know I redundantly said it twice.) Perfect excuse to buy a new saw.

My small Delta saw has always done the same thing with a dado blade...I usually have to put a clamp on the blade raising/lowering knob to hold the height position.

On a positive note the grease does make it real easy to raise and lower the blade.

I bought this saw when Jimmy Carter was in the White House. Unfortunately a new table saw isn't in the budget right now.

All the teeth are present. This dado set isn't recommended for and underpowered saw, which mine is. But, unfortunately I own it and it has worked well when it stayed put.
I'll see if I can rig up something to lock the blade height.
