I fired up the unisaw for the first time today! I have never owned a unisaw before or used one so I have no idea if it’s running smoothly or not. BUT! I will say that it sounds amazing. Here is a short video clip of it running.

How am I supposed to know if everything is ok? I mean it seems ok. No weird engine noises. The blade stops faster than my little dewalt stops. Is that normal? There is also a “thud” as it slows down.

Anyways, I’m just gonna finish making the covers for the saw and then move stuff out of my basement, pull up the carpet, run the DC pipes, and build an outfeed table, build an extension table and then I’ll be able to start making things.

I’m just super excited it’s even turning on!

Oh forgot to post this picture of it almost finished.

And anyone know where I can find these L brackets that hold the extension table to the TS?

Have you tried the nickel test? Where you put a nickle on its side on the saw and see if the vibration of the saw knocks it over. The nickel should stand on its saw from startup to shutdown. It’s one of a few ways you can see how much the saw vibrates.

Looks good and sounds good to me.

Nothing wrong with the way the saw sounds….it sounds just like my Unisaw when it kicks on and off….The noise or “kick” you hear when the saw turns off is the induction motor coming to a stop, or shutting down…..nothing to worry about…..they all sound like that…..

And you can find those L brackets at any hardware store, or Lowes or Home Depot….they all carry them…

You want to check to see if there is any wobble on the saw blade (assuming you have a flat blade).
Less wobble = less vibration. Can’t really tell from the anle of the video. you will need to be dead on.
Ideally, measure with a feel gauge or a dial indicator. Ultimately, you want the flange and washer to be flat!

You will always get some kick during start / stop.
Check your table for flatness.
Check your fence to see if it is square to the table.
Check the miter slots to be parallel to the blade.

Perhaps you could farther tuning it farther or have to live with it. You need to be aware of what you got and what you are dealing with.
