We have that model. The short answer is twofold
- we don’t think you can
- we have not found it necessary
I’ve just gone out and measured the variations in the measurement from front of blade to its equal point on the mitre slot compared to the rear of blade to its equal point on the mitre slot.
The variations are from 0.18mm (front nearer the slot than the back) to -0.23mm (front further away) as we measured in many places on the blade.
However, we suspect the variations are caused more by the wear and/or manufacturing tolerances on the blade than any variations in the axle and/or bearings. I guess you would have to install a perfectly flat disc instead of a saw blade and measure again.
We guess that the initial cut happens at the front; the speed at which the blade revolves equalising any variation and that the saw cut is only the initial “rough” cut before finishing cuts take place mean that the variations we have don’t practically matter. That is, we rely upon the reality that we have never had issues with the performance of the saw.
We are happy with the accuracy of the cuts achieved and, if we have had any kickback, it’s been extremely rare and due to operator error.
If we have/were to find any unacceptable error in manufacture from suppliers such as Axminster, Classic HT, Woodworkers Workshop, Workshop Heaven, we would reject and have no doubt, based upon rare experience, that these suppliers would accept without any question.
