« Part 2: Router Bearing Replacement: Fix It, Don't Trash it! Part 3 of Machine set-up series no next part

Recently, I watched some of a woodworking video. I say some, because once I saw the presenters method for checking square on the TS, I turned it off.

This is not squaring up a blade in reference to the top, it is getting square in reference to the insert. Little demonstration on how this will steer you wrong. Square, but not 90 degrees to the top.

If you have a quality combination square, this is the way you square a table saw blade. It’s the way I was shown and I believe it to be the most acurate method.

Surely this has been in a magazine article somewhere….. Just bringing it to the attention of any interested party.

I don’t claim to be an expert.
Far from it.
But there are few guys making videos out there who are less knowledgeable in woodworking then a trained chimp.
And, unfortunately, they are messing up the newer guys who are even less knowledgeable.

That is great for vertical and using the same square to reference off the miter slot does for horizontal.

That’s the internet for you,
A little Knowledge is dangerous comes to mind.
It almost mandatory when watching some videos that you know better in the first instance and disregard the information presented unless its something you didn’t know.
Always rely on the “Its too good to be true” as in most cases it is not true and borders on a dangerous practice or dangerous event.

Our tools and also our timber are very precious to us and we don’t need to be wasting either by being mislead, causing injury and ruining our projects.

Good post that’s the sort of exposure required.

If your insert isn’t square to the top, wouldn’t it angle the cut as it ride over it?

Use the straight edge of the combo square to level the insert with the top. Most will have adjustment screws on the four corners. If you are ripping wood, narrower than the thin side of the insert, I would make sure the length of your stock, easily spans iron to iron.

Right…so if the insert is level with the top, then there’s no issue.

The insert “floats” in the top and is not a solid or consistent reference point for square. For the most accuracy in any stationary machine, square from a known flat, rigidly attached surface with the largest square that will work.
