i bought a dado set used from a contractor. 3 of the spacer blades were waxed so i figured in good condition. when i took the wax off, the cutter tip (on top) was shorter than the opposing side (on bottom) – see picture. am i suppose to file down the bottom side? could it be that the tips were replaced an put on too short/low?

Don’t know what you bought, but I THINK the side opposing the cutter is there to limit the bite it can take to preventkick back. Any filing you do will sure unbalance the setting making for a VERY DANGEROUS SITUATION. If it runs smoothly, leave it alone. If it doesn’t, get rid of it.

Set it up and run a dado. If the bottom isn’t too rough, you’re ok.

Thanks guys. I have run it through the machine and it is not a smooth cut at all. the higher non cutting side provides friction and pushes the wood above the blade. one of the 4 inserts appears to have been filed down and that cutter runs smooth.

With those anti-kickback fingers sticking up above the teeth, there’s not much chance they’ll cut anything. Looks like it was resharpened repeatedly. It’s hard to imagine a competent sharpener doing that. Some of that material has got to go if that sets going to cut again. Here’s what the Freud Diablo DD208 dado set looks like:
