I had something really strange today and I spent the whole day trying to find the issue.
I had some of my blades sharpened so I switched the old blade for the freshly sharpened one.
When I was ripping 18mm birch ply I noticed some strange behaviour. The board would not stay against the fence when feeding it through.
Seems like it got slightly pulled by the blade away from the fence. But I didn't feel any resistance when I was pushing the board through.
Even when I was using my jessem clear cut stock guides this still somewhat happend.
I switched the blades to my old one again and the issue went away.
I started inspecting the cut and it I also noticed it wasn't square (vertically). so I re-squared the blade with my wixey digital square.
it seemed to be at 90° but I re-squared it again to be sure.
fed the board through again... yet the cut was still not square.
took out several of my machinist squares and they all showed the blade was perfectly square to the table, yet the cut didn't came out square.
I even went out and bought a new Stehle blade.
I noticed I had to place the blade at 91.3° (on the wixey) for the cut to come out square(ish). Before you ask, yes, I did zero out the wixey by placing it on the saw table first.
I started fearing that there was something seriously wrong with the machine alignment or something got bent.
I took out the blade again and also took out the big "washer" that's behind the blade. gave everything a spray with the compressor and reseated everything properly again. and used my old blade. before testing I also noticed that the speed setting of my erika was at its slowest setting, so I set that to max speed.
Ran the board through and...it seems to be back to normal again....will do some more tests tomorrow but I'm way too tired now
This story is the short version, in between all this I did tried several squaring sessions of my fence, blade changes,... but I never took that back washer out (and there is also the speed setting). I was also thinking that the sharpener had wrongly sharpened the blades and made the blade unstable while spinning. But I couldn't notice and runout or wobble. All in all, quite a frustrating day.
Anyone here that has had this kind of issue?
