Safety (or the lack thereof) #3: DADO BLADES CAN'T CUT 1 INCH OF HARDWOOD IN ONE PASS

I’m a BONEHEAD.
I like my Dado blades.
But they have their limitations.
Especially pulling the blade through on your radial arm saw.
Ripping a 3/4 inch dado 1 inch deep in a piece of hardwood tougher than oak (I have mallets made from this stuff) exceeds their ability
When you try anyway the chippers decide to group together in a show of rebellion and the teeth get mad enough to fly off the handle…er…blade.

I knew better.
I was in a rush.
The fix was $75 at saw stop getting new teeth brazed on.
At least the new teeth are better than the old ones.

good night Irene.
Dado stack $75
Chunk of wood $2.50
Scraping 11 pounds of crap out of your BVDs….....priceless
Good thing youve been living a clean life. This one could have cost you.

Reading your tag I see that you are somewhat familiar with not using it right but this time I think that it really is broken.

Thanks for manning up and 1. admitting the mistake and 2. sharing it with us. You don’t mention an injury so I am assuming you didn’t incur one. That, of course, is a blessing.

That musts have been some tough wood. Glad you didn’t get hurt, and good of you to warn others.

The old adage about big bit small passes would apply here.
Glad you are okay. Sometimes we all have to learn the hard way.

I am surprised you could even fit a dado stack on a radial arm saw, their lethal enough with a “normal” blade.

Remember easily digestible bite sized chunks only! goes for the poor radial arm saw as well!

I am guessing it went for a “walk” up the timber.

Remember when tungsten teeth meet is always gonna be a nasty outcome!

Take care we need our LJs.

And post Jumbojacks comment on the wall next to the saw !!

And No you cannot borrow any of my tools!!

Otherwise enjoy!!

Rob,
I actually have TWO RASs, a Craftsman I can’t seem to sell for anything on Craigslist, and a RIDGID.

Since I can’t get rid of the Craftsman I have both of them set in line with each other.
The Craftsman is now a dedicated DADO machine.
And I’ll admit I have to take the guard off when using the DADO.
But when I do that I lock everything down with clamps and keep myself off to the side with a full face-shield on.

And the blade did try to walk up the wood.

Pete

I checked out some of your links, I hope the finger I saw was not yours!

I also do quite a bit with recycled timber you may want to check it out when you get a moment.

Robert,
It was me.
And the ER doctor was not amused that I was taking pictures.
I told her it was going on my blog so someone else would be careful with that tool.

You’d think I’d have learned by now.
But I find that Attention Deficit Disorder (ADD) is a dangerous thing in the work shop.
Usually I watch for signs that I’m not focusing and stay clear of moving parts.
But sometimes, specially at the end of the day, or if I’m rushed, it sneaks up on me and I forget to check the details.

Fortunately, knock on wood, a few minor cuts are the worst of it.
And you’re on my buddies list now.
Thanks,
Pete

Yo Pete!

We all have our days I managed to shoot a brad into my finger when I was building a dolls house for my No 2 sons daughter Caitlin.

Luckily I had a vice on the bench and clamped it into so I could pull it out.

No ongoing problems apart from my finger twitches nervously every time I use the nail gun now! :]

I will enjoy your posts!

-- Regards Robert

Oh Robert ….
Porter Cable 16 gauge finish nailer with 2 inch nails…
Through pegboard into 2×4 for a customer’s display stand…
Nail turned when it hit the 2×4 and of course turned toward the finger that was just under 2 inches away.
