So as I was unpacking it and admiring all the oiled heavy cast stuff, I found the factory inspection record. Jet obviously wants you to see this as its prominently packaged in its own plastic sealed envelope with the inspector's hand-written measurements.
Run-out of Arbor Flange Allowed 0.0008 inches Measured 0.0008 inches CHECK
Minimum blade height Allowed 3 1/8 inches Measured 3.13 inches CHECK
Parallelism between blade and mitre slot Allowed 0.0118 inches Measured 0.054 inches UH-OH!!!!!
Yep, according to the inspection record, the last measurement is 4.5 times greater than allowed. Now if this was a $99 eBay special saw, I wouldn't bat an eye. But I paid for a little precision here. I thought I must be misreading it, or it must not be that important. I called the dealer, who is also an authorized Jet repair shop. Their saw guy was speechless. He acknowledged it was out of tolerance. He has never seen the factory actually measure it out of tolerance and ship it anyway. Just to be sure, I scanned the inspection record and faxed it to the dealer. He agreed that I was reading the number correctly.
So hopefully we will get this resolved. Are there any wood tool engineers in this conference? Is this difference really important or is it splitting hairs?
