Here are the tools that I am using to align my blade to the miter slots: 1) Neoteck DTI Digtial Dial NTK012 indicates 0.01mm/0.0005" 2) Neoteck Digital Level NTK034 Box (Resolution: ±0.01 Degrees at 0-1 and 89-90 Degrees; ±0.05 Degrees at the Rest Accuracy: ±0.1 Degrees at 0-1 and 89-90 Degrees; ±0.02 Degrees at the Rest) 3) Digital angle finder https://www.generaltools.com/5-in-digital-angle-finder Accuracy: ±0.3° Resolution: 0.1°
When I test #2 against the 90 degrees of a carpenter square is dead on !
The digital level is not that stable and I am thinking about returning it
My question is: what is an acceptable deviation from 90 for a table saw like Rigid TS3650? (blade raised at 3" above the table level and it should be as square as possible to the table top)
I guess it will depend on the task so here are my near future plans:
-kitchen island frames
At full blade height I get a 44.8 for 45 degrees and 89.6 at 90 degrees measured with tool #3 The above mean that I can't push the blade any more toward any of the extreme angles
