Let me comment on the comments, then I will crawl back into my sawdust pile.
1. Precision is important in any tool test. Most of us can't measure more precisely than .001 inches. I think it is incumbent on the tester to use any available methods to accomplish those measurements that most of us can't muster.
2. Noise level must always be measured for like equipment. Testing a jointer with Shellex cutters is not the same as testing with standard blades. Don't test one against the other. Example, my cabinet saw cranks out about 92 db with the dust collector running. However, my jointer with DC cranks out 102 db due to the loud noise of the spinning blades. Measurements made by a Radio Shack sound meter.
3. Customer service should also be a consideration, but IMO it is secondary. Most of the power tools we have in our shops are not delicate instruments. A jointer is a rather simple machine, so for me customer service is almost a non consideration. The same can be said for a cabinet saw, or even a band saw.
4. Fit and finish are also low on the list. I don't buy a tool for its innate beauty. I want performance, appearance is a far secondary. I define fit and finish as those exterior items like does the doors fit well and is the paint of good quality.
5. We expect our blades in our planes to have Milli-micron sharpness, why not hold other manufacturers to the tolerances that we hold ourselves to when honing a blade?
I can only regard these reviews as what I call "rock and rat" filters. They can eliminate the truly bad products, the rocks and rats, from those items that need further consideration.
Now where is my saw dust pile.
