Been at this for 15 years and never used a fancy table saw
alignment jig. I hold an ice pick against the miter gauge to
and use it to check parallelism.

I have a slider now so no miter gauge. Anyway – the quality
of the saw (free of defect) and a decent blade matter more
than the quirky setup gauges, imo. Table saw is not substitute
for a jointer or hand planes. Getting accurate crosscuts in
24” cabinet sides can be achieved with a sled in most cases,
but better saws have more power and less runout/burn.

Miter gauges pretty much suck for crosscutting anything more
than lightweight and small pieces. The problem with American-pattern
table saws is the reliance on an 80-year old design concept,
not a lack of ability to be setup easily to acceptable tolerances
in terms of blade parallelism to the miter slot.

I agree with Loren, you dont need a lot to calibrate the saw alignment. I typically use just a square.

I respectfully disagree with the toe-out suggestion. :) This presents a problem when the fence is used on the opposite side of the blade (usually for beveled cuts). I don’t do this often, but I did it tonight. Miter slot, blade, and fence all should be dead parallel. If you are getting skiff marks from the rear of the blade, then the cause of that problem can be determined and fixed.

Edit: I’d add that a dial indicator(DI) would be a good compliment to your calipers. GarageWoodWorks has an explanitory video on how to use the DI.

Another vote for avoiding toe-out. A TS is designed to operate with the fence parallel with the blade. Deliberately introducing a misalignment makes no sense to me. It isn’t that difficult to get a good aligment

I’m also in the dead on fence alignment camp, and I don’t get any “skiff” or whatever they are called when I use a quality rip blade.

Everyone will have a different opinion, and the best thing to do is try a couple out as see what works for you. I recently bought the A-Line-It basic kit, and would highly recommend it. It is a great product, and has easy to understand directions/videos. It’s $150 but well worth it.

+1 for keeping blade+miter+fence in alignment. what more it is easier to keep everything aligned the same way then having to remeasure blade-fence and blade-miter slot (you have 2 miter slots by the way). also if you use a sled you’d want the blade to be parallel to the miter slot or you’ll run into trouble.

that said – like other have said, I simply use a standard combination square to align my TS and I have had no issues with it (FWIW I have a dial indicator, and after aligning my TS with a square I checked with the DI and found out that the TS was aligned well enough to call for any expensive alignment tools)
