Keith that could become addictive in a short time. First time I have seen this. Maybe a good way to use up scrap and be educational too. Have to compete with the cell phones some way.

About the table saw accuracy, I would rather spend time woodworking than tuning my tools to the .001" , if it is ,001" too big, I can touch it with a sanding block or block plane and make it fit. Wood workers make things fit, a machinist makes things that fit.

 

Also like Gerald said wood expands and shrinks, I have had flat tops expand and shrink both ways length,width, and thickness. A good example is a wooden boat or wooden bucket.

I made some "Keva Planks" for my grandsons a few years ago.   To work right, they need to be pretty close.   If I recall, I ripped the strips then ran through a planer to get within a thou.    I know a guy nearby that makes wooden "burr" puzzles that need to be fairly precise to work.   He said that his planer (not necessarily be design) cuts about 1 thou lower on one edge than the other.   So he runs them through the right side and if too thick runs through the middle or left.

 

I can tell you after doing 1024 planks that each plank has six sides and eight arrisses.  Thankfully, they do still play with them.

The Keva Planks may have led to the Jenga game.

I used the PALS to get my contractor saw dead nuts on. It was very easy that way.  I used a dial indicator on the same tooth measuring from the in feed and out feed ends of the blade. 

 

When I made my cross cut sled I used the five-cut method to check the accuracy and my saw is "perfect" zero-zero.  I also also added 3/4" MDF to my rip fence and usually use a feather board to keep my wood pushed against the fence.  I made a zero clearance throat plate and installed a hardwood splitter that is just a hair offset toward the fence. So far I am very happy with my Sears Contractor saw.

 

OK time for another story.   A late friend of mine was an aircraft engine engineer.   He was a true wood craftsman and like to work in "thous"    He often said, "That's not a quarter of an inch, it's 250 thou."

He said a friend of his took his cast iron table saw top into a machine shop and asked the proprietor, "How much to machine this top perfectly flat?"

The guy looked at for a minute and said, "About $10,000."

Shocked, his friend said, "That much to just put it up on that machine and grind the top?  Are you kidding me?"

"Oh, we can grind it on that machine for $200, but you said you wanted it 'perfectly flat'."

And it's gonna stay that way till sometime after Christmas!

and it's that much too small - ignore it or if you must fix it w/ some ultra fine swarf....

Sun was shining on the machine....
