Learning the hard way

The thing is make sure that all the blades are tight up against each other when you snug the nut.
Make certain that the first blade if tight against the arbor flange. It can slip off when putting on
the chippers.

I had a guest in my shop do the same thing once. Thank god it was my cheaper dado set. I snug each as I go and after tightening the nut, give it all a wiggle to see if all is good. Never hurts to double check.

Ditto Gary’s remarks. Once the stack is set then I tighten it down.

My condolences on your dado set. They can be repaired but you are the best judge of whether it it worth it or not.

Glad you weren’t hurt. My recommendation for replacement; Freud Adjustable Dado.

I agree now that I have had this experience. I was a bit down after doing this, but in hindsight, I am glad I did not do it someone else’s dado set and of course no injury. So it turned out to be a just a hard lesson learned.

Ok…. The possibilities of injury there a just wee bit scary! Seriously, thanks for the reminder.

After changing my blade i flip the saw on and off. I like to check and make sure the blade is running true, and then I’ll recheck the nut to make sure it is still nice and tight.

im still crying for your dado :((

Unfortunately, the best way to achieve a new respect for tools and machine. Thank God blades can be replaced much easier than fingers.

I found two web sites that sell replacement blades for my Freud SD208. I ended up damaging three (3) 1/8” chippers and the left outside blade, leaving only the right outside blade and the 1/16” chipper in working order. The best price I have found for replacing the damaged blades is $62.00 without shipping cost.

I have began thinking, I might be ahead getting a new dado set or maybe upgrade to a different set – no firm decision as yet. I will have to save a while anyway.

Depending how many tips you have missing, and the worth of the dado set you have, it might be worthwhile to check Forrest Manf. They will replace tips as needed with their sharpening service.

Thanks Tmuli for the link to Forrest repair services.

I have three option that I can assess.

to add to what folks have already said

the outside blades usaully have a “this side out” printed on them and no “2” teeth should touch each other. rather having the chippers at 90 degrees to each other to balance the wieght on the arbour…....does that make sense?

One thing I’ve noticed on my set of Grizzly dado blades is that sometimes the shims fall down in the threads on the arbor. The blades weren’t stacking up against each other like they should have until I tightened the nut. When I removed the blades I noticed that a couple of the shims had small pieces missing from the center hole. Has anyone else had this problem? If so, how do you solve it? It’s hard to come up with something that won’t add thickness to the dado set.

The way I have set up my dado has been to firm up the left side outerblade against the leftside flange, then adding wing chippers alternately at 90 degrees to each chipper and checking to be sure no tips do not touch and interspersing shims between the blades as needed.

I believe my error was not tighting the retaining nut tight enough. I had trouble loosening the retaining nut from a previous work session and ended up slightly damaging the retaining nut. So with that experience, I think I subconsciously tried not to over tightened the nut when mounting the dado set. I thought I made sure all the blades were seated firmly against the left side and then tightened down the retaining nut. But things went awry anyway.

On Juniorjock’s topic,

I am such a novice, that I will leave it to other more experienced LJ’s to comment. I suggest that you may want to start a new forum thread with your topic so your topic is isolated to your specific question. I would be interested in reading what other LJ’s have to offer on your topic.

Dalec, I did. Right after posting it here.
