Hi, I want to make a double blind dado on my table saw for a dovetail box I am making. how do you do this safely. I can find many videos on making a dovetail box on utube but they only show the dovetails. I can’t do it on my sled

Are you sure you want to use a table saw and dado blade.
A router with or without a table is a lot more sensible.
A router is the method I use
Good Luck

A picture would help. What is the dado for if the box uses dovetails? To hold the bottom panel?

As others have said the router is the better & safer solution. The “stopped” TS dado, won’t. The curve at the ends will make the fit both sloppy (ends ill defined) and prone to binding.

Safely is the key word. Against a fence I think nothing about using stop blocks, and dropping a piece of stock on a spinning router bit at shallow depth to run against the fence to the far side stop block. Do that all the time. Increase depth a few passes and done. You will have chisel work if you need square edges, but I find it easier to round off the tenon part.

Because of that blade coming over the top, right at ya. I get a little tight in the end zone thinking about that on a TS, so I use the router table. I have seen video of people explaining how to, (pretty much the same as RT) on U tube, still I find my warm and fuzzy zone absent. Plus with the blade it makes a graduated depth at both ends, where the router bit can bring you right to the line full depth.

I have 2 options chisel or TS. I do not have a router. I am using the dados for the bottom and lid. I know the slot will be shallow on the end, will have to clean it up with a chisel

It’s done all the time but demands your full attension, but safer with a router.

Did I mention I lost the tips of two fingers in 1985 doing blind dados..

Well that pretty well cakes it. Nothing tells a story as completely as a picture.

Karda has anyone told you how much your going to love your new router table set up, let me be the first. You do enough woodworking you will see hundreds of uses for it.

Run the dado and glue a piece back in.

Glue on fingers doesn’t hurt.

I’ve tried blind dadoes on the table saw. Chiseling that curve out is a pain, as far as I’m concerned.

If you must do a stopped cut on the table saw, I’ve found it’s best to have a stop button that can easily be activated with a knee bump. That way you can get the work piece to your stopping point and then bump the saw into the off position without moving your hands (which are hopefully well out of the path of the blade.)

Filler blocks are useful in many circumstances. Of course, if your project involves highly figured wood, then they are more difficult to hide.

Cut a full dado and glue in blocks on the ends is probably the only way I would do this on a table saw

No need for a stopped dado. It can still be hid even without a piece glued in.

I’ve done it with a box joint all on the table saw with through cuts and no gaps.

If you carefully space the fingers on the joint and vary the depth, you can use a through dado and still have no gap.

I don’t have a photo on my work computer.

This information may be of interest.

If part of a finger is amputated, the priority is to look after them.
Sit them down, reassure them and maybe call Jack Duren! ... grab a cloth to apply direct pressure to the stump, elevate the injured hand above the level of the heart. Do not worry about the amputated part until bleeding has been controlled and the child is calmer. Pick up the finger. Do not wash it. Wrap it in a cloth, put this in a plastic bag and then on an ice pack. WHAT ABOUT IF THE FINGER IS BRUISED?
If fingers are crushed and bruised, but there is no amputation, run the damaged area under cool running water for 10 minutes.
After this, apply a wrapped ice pack, elevate the injured hand and seek medical advice.
Do not let the ice come directly into contact with the amputated part as it will cause ice burns and mean the finger can’t be to be sewn back on.
You are chilling, not freezing the amputated part to prevent it decomposing.
Transport the child and amputated finger to hospital, if necessary by ambulance.
If the finger is still partly attached with a blood supply, bandage the severed part carefully in situ, not too tightly, support and elevate the hand and finish the call to Jack Duren then call an ambulance.

Joke:- I had a friend cut all ten fingers off, when he got to the hospital the doctor asked him why he didnt bring his finers with him!
