Learning Opportunity #4: What is the thickness of a human hair?

What kind of saw does he have that hasn’t been aligned and yet is that accurate. I want one! I think you’ld have been much happier aligning mine Don. Too bad we don’t have the Cyber buddie share so I could get you to straighten it out.

You’d probably have found a variance equal to several hundred of my hairs on my saw. (that is, of course, after I’m freshly shaven)...

I second Bob’s comment – that is some accurate saw!

It took me over a year to figure out why my sticks were getting burnt. I adjusted my table saw with a hammer last month and it’s much better now. My remedy is a simple one. Use this saw for dado’s and buy me a new saw. How’s that sound fellas?

You already have a cast iron top table saw Obi, no fair. They get me my 3hp 220v cast iron table saw first.

I alluded to the time it took me to calibrate my saw – but I wasn’t happy with a variance of .016mm, I got mine to .008mm. I wouldn’t have sweat it so much if I’d only stopped to think about how ridiculous this kind of tolerance actually is.

Bob, my friend and I both own the same type of saw. It’s a twelve inch, 3hp Taiwanese generic, sold under the brand Leda in Australia.

Keep you eye out on Craigslist Obi. Seen at least 2 cabinet saws for under $500 in Modesto in the last month or so….

Don, have you tried the TS aligner for any other operations?

Yes, I also calibrated my TS Fence as well as my Router Table Fence. In essence, these three operations are quite similar and use the TS Aligner in the same way, ie mounted in the miter slot.

The only slightly different setup I’ve tried so far is to calibrate my TS blade at a 45 degree angle. Whilst the TS Aligner Jr. is still mounted in the miter slot, the difference is the use of the ‘Angle Attachment Gage.

Once it was accurately reading 45 degrees, I adjusted my trunnion stop ever so slightly to assure an accurate angle. At this point I can’t ever see myself using the aligner for determining other blade angle settings, but who knows?

I plan to use it on my jointer and drill press at some point, but I want to get my head around the use of the TS Aligner Jr. before I do so.

that reminds me of the time when we got a “die press” machine at our resource centre for teachers … they could cut out shapes of cats, houses, moons, and a zillion other shapes with the press of a lever…
When asked if we had a “square”, (no), some were really disappointed because they didn’t know what to do—they were so used to the die press for all of their cutting that they forgot that they could simply fold a paper and cut.

Back when I was taking a course from Ian Kirby he often talked about precision and, he being British, measuring in millimeters instead of inches.

A classmate then commented that machinists commonly measured to ten thousandths.

Kirby’s response was that scientists worked with microns.

It’s all perspective, not to split hairs ;>)

-- No piece is cut too short. It was meant for a smaller project.

Personally, I don’t see a problem with setting up your saw to be as accurate as can be. Of course, I understand what you are saying about the naked eye not being able to pick it up, but it is almost like that project you made for someone that has a not so perfect something or the other. The person you made it for will never know it, but it still bothers you because you know it could have been better. Great story, Don.

I think that it is great that Don is bringing this to our attention for many reasons, but I will limit myself to one: If enough of us care about accuracy, and the more we woodworkers demand of our equipment, the more the manufacturers will respond.

Looks like I need to invite you over for a visit!
