Thanks David,
Like you and Lucky described, I do the cut test to confirm calibration. I calibrate with precision 90 & 45 squares.
I am just curious what my wixey angle gauge does. If memory serves me right if I zero it on the table it shows 0 or 90 depending upon which side I use on the blade.
I do not like using digital angle gauge for calibration because, well it is digital; you do not know when it is going to flip plus it does have repeatability error.

For the 90¡ã stop, I cross cut a 1x3 on edge with the blade fully up, flip the off-cut over, put the two pieces back together on the bench and check with a straight edge. ?Same method with a 1 x 3 at 45 and check for square.

I guess i will need to check my angle gauge now. I did not use it to calibrate 90 & 45 stops on the saw though.

I¡¯m with Lucky on this one. ?I have not found that the digital angle indicators produce very accurate results when used the set the angle stops on the saw trunion.

Hi Mark:
When calibrating my Kappa, I tried the tilt box method and was surprised how inaccurate it was for me. Maybe the fact that the tilt box is not accurate enough, or maybe the fact that a saw blade body is not necessary ground flat, or a combo?
For me, making test cuts in timber and measuring the results yielded the best calibration. 90 degree cuts in two thickish pieces, butt together and check with a straight edge. 45 degree cuts and then check for square.?
I¡¯d be interested in whether the tilt box works for you. Cheers.?

I have the procedure, is a digital tilt box accurate enough or am I better of using a vernier scale protractor like the Mitutoyo 187-201. Looks like the tilt boxes are accurate within .2deg.
