I have a ridge carbide dado, I gave it back to them last year to redo,

I needed to use it and it was heavliy rusted. They probably never put a
rust preventitive on it after recutting the teeth. So I clean it up, and
after using it, I hate waxing dadoes because they slip while on the
arbor. But I had no choice, any rust preventitive was going to be a lube
too. So after lubing it, I started thinking how am I going to keep them
from spinning into each other.

I took out my engraver and just kept putting lines in a star burst from
the arbor out, but actually brought them from out to the arbor hole.

They lock nicely and don't slide, each face probably added less than 2
10 thous so it's all good.

Just a tip brought to you by the woodchucker.. who is buried under
snow.. 12-16 expected here today. I usually get the top end as we are in
the mountains, but I am in a valley in the hills... so it just dumps
here. I must have heard hundred times from the wife... do you have gas
for the snow blower... :-(


Good tip


FWIW I have a Forrest DadoKing dado set. I love the set but like you my
set will spin some times, some times not.

Here is what I have determined. Mine spin if I don't use the washer
between the outer blade and the net. The friction between the nut and
the outer blade causes the blade to reposition when I tighten the nut.

When cutting a narrower dado and using the out side washer I get no
spinning when tightening the nut.

is your spinning a result of wax or lube? or just steel to steel?

NET???
