Looking for a gauge to align a table saw top. Is there a HF version of the A Line It kit?
Similarly has anyone tried the Mag Dro Miter Caliper Base as an option?

Do a search here for tablesaw adjustment jig. I’ve seen a few posts where people did as above, makes it easier to follow the bouncing ball.

Really simple affairs can be used with a bolt, or a screw into a board as the pics show.

I did mine a little differently. I used a bit of pipe to ride the slot. Basically no clearance to the slot error.
Remember to use the same tooth.

tvrgeek, did you weld on the slotted flange or is that something you found/repurposed? Looks like nice solution.

Yes, just a bit of band iron onto a bit of black pipe. You could just as easily use JB Weld. Or notch a bit of angle iron and screw it on.

One could use the runner like the wood jigs and add a couple of screws to expand it to fit the slot for the goiven humidity. I use HDPE runners for my sleds and fit three screws in undersize holes so I can make them as snug as I want.

Better than using a tooth of the blade is to make a scrap piece of wood fit onto the arbor, giving you more swing. Tim Conway does a good job explaining here:

I use the Mag Dro caliper jig. Works well, despite being a $9 hunk of molded plastic and hardware. :)

Only caution is make sure your caliper does not have electronic readout with large protrusion out the back. Have 30yr old Starrett electronic calipers that does not fit Mag Dro properly. Standard dial caliper, or newer electronic models with smaller plastic case work fine.

Cheers!

That’s what I ended up ordering. Seems all jigs either needed more $ in supplies or access to an already tuned saw, which I don’t have .

Agree with TVR. Million ways to skin the cat here. Ranging from cheap to expensive.

Aligning a table saw isn’t something I do often. So when I recently upgraded my saw, I just made a quick and dirty jig. Built a fixture with some scrap wood and clamped it to my miter gauge.

I prefer a dial indicator over calipers. Right or wrong, I find the former is more reliably precise in this application.

Whatever you do, make sure you’re eliminating any play when measuring. I did a lot of repeatability and reference testing. Just to ensure I wasn’t introducing any error into the measurements.

I use an ice pick held against the miter gauge. It’s pretty sensitive though I am sure not as precise as a dial indicator method. It’s been accurate enough for me.

I just use my combination square. We are talking about wood working after all. My table saws manual say that as long as it is within 1/32” (wider at the back), it is in spec.

DITTO!! Nice to hear someone else say that. I gave up saying it.

+1 on the combination square I have used that method for years. When I give presentations at the local woodworking store on the Tablesaw that’s the method I show them. I just have to be careful and make sure the Sawstop is off so it doesn’t need to have the cartridge replaced. If that happened they would get an added demo on changing a cartridge.

To clarify…the 1/32 spec I mentioned is for the fence not the blade to miter slot setup. The blade/slot setup close enough to perfect to not be noticeable.
