I have a 1965 Sears Craftsman 10" contractors table saw that I've brought back to life, so to speak. I've made several upgrades to acessory components on the saw including a PALS alignment kit on the back truninon.
I've not been able to achieve consistent blade to miter slot alignment equal to, or less then, 0.003".
Aftermaking a cross-cut sled and attempting to align the front fence, I discovered the blade was not acceptably parallel to the slot. I used a metal ruler with 1/32" graduations for measuring front and back of blade measurements. When raising the blade to its highest vertical postion, there was a 1/32" difference between the front and back of blade measurement. The difference decreased when the blade was lowered to several positions so that when it was approximately 2" above table surface level there was a difference of 1/64". When I took the link belt off the blade and motor arbor pulleys, I had no difference in front and back blade measurements, but when reinstalling the belt the difference was approximately 1/64" at a 2" blade height.
Can the alignment of the blade and motor arbor pulleys and/or tension of the link belt throw off the blade to miter slot alignment? Does the measurement difference with the link belt on and then off indicate a problem with the blade arbor flang or bearing?
Your thoughts and answers will be appreciated!!!
