I've had the Anderson square for 1-2 months. Mine is not quite square. It's 1/100" off. Measured with feeler gauges and a woodpecker 18" aluminum triangle and other methods with a Veritas straight edge. My table saw crosscut sled is now within a thousandth, so I'll just re-square the Anderson square on the sled. Oh well. Had a QC sticker but don't think the CNC nailed it quite like it should have.
Did you use a try square to check the triangle?
I don't see how you can accurately check the square of a triangle with another triangle feeler gauges or not.
1/100 off isn't bad. Condsidering the method you used inherently has error.
Woodpecker guarantees theirs to be with in .0001 so that's pretty darned good.
Both of Mine ( yes I got 2) I checked with my woodpecker 1281 square and it was dead nuts on.
I set up a Aldendorf saws fence and sliding table yesterday using the square , got it dead nuts on verified using the 5 cut method. It was dead nuts.
For $19 ya can't really complain considering the WP 1281 is $99 and the WP 45cm triangle OTT was over $200 so a triangle square that cost $19 gives accuracy to by your method .001 is pretty darned good. Well with in the limits of wood working. After all we are not Astro physicist working on absolutes theoretical design for NASA life support on the future space station or Mars colony
Its .01 not .001.
I ordered 2 of them, they should be here today. If mine are not dead nuts then they are going back.
.01 is unacceptable. This "Well with in the limits of wood working" mindset that a lot of people seem to have drives me nuts. [eek] Its what allows manufacturers to have crappy quality control and not improve their product.
If my tools are off by more then a couple thousands it almost always show up in the end result. Sometimes it matter, sometimes it doesn't. [smile]
When you drill a hole in a piece of wood , do you take a hole gauge and measure it? If its not perfectly round do you toss the wood and start over?
When you put a drill in your drill press do you spend a hour or so setting up a dial indicator and adjusting its run out to insure its dead nut on with less then .0001 ?
When you joint a piece of lumber do you take a mic and measure the width a d make sure its with in .0001 tolerance. If it is and you leave it in a shop thats not climate controlled come back the next day and discover its not with in that .0001 tolerance?
Do you toss the lumber and start over?
If .01 is unacceptable to you then why waste your time with a $19 square or a WP square that cost a measly $99 and a tolerance of .001?
Why not go spend $500-$1500 or more and get one specialy made for you from a precision shop that has +/- 00005 tolerance?
Even then you have to use it in a climate controlled shop to avoid any movement in the metal.
Im happy with the cuts I get, I realize Im not building the Mars explorer out of a material that has natural movement greater then the tolerances Im trying to maintain. Then try to keep the wood movement in those tolerances...
