So here is some updated info on this issue, geese really sorry for all the text it required more explaining than planned…

?

Honestly the techs spent so much time (2.5 days) just trying to calibrate the replacement AD941 and the Saw that they were toasted by the time they were to troubleshoot the vibration issue, they tried to blow it off however I reminded them that they first initially said that they noticed the vibration as well notating that it was worse in the chassis. The Saw is still way out of calibration but lets save that for later.

?

Back to the vibration…

?

The scoring belt was removed with no real change, then the blade, no real change then the motor belt with no real change. That indicated that the motor and or the pulley on the motor was the culprit.

?

The motor and pully was swapped with new and I noticed an immediate change in that the vibration - the ?kinda low freq sound I was hearing was gone and virtually no vibration. I couldn’t believe it, I was absolutely thrilled that the issue was resolved - that was until the drive belt and scoring belt was put on, the vibration is a little different but seems like it actually increased, it’s noticeable more than previous with the riving knife vibration.

?

Basically the that’s where the tech’s left it, they were like oh well. I assumed when Felder told me they would trouble shoot the issue they would actually have a plan and methodically go through it, the dial indicator didn’t come out once to measure arbor run out, blade run out, any of the scoring components etcetera.. but this is not a bash email, just some background.

?

A few interesting things, on the last tech visit maybe late October the main and scoring were removed by the tech and then reinstalled, I had been using the saw about 1 month when Greg Bryson from Felder contacted me about the poor saw cuts and had me do a little bit of visual checks which included looking inside the saw cabinet. What I found was that the scoring belt was not reinstalled correctly by the tech (pic attached) it was of a few teeth towards the slider, I couldn’t believe the tech did that so I put on a new belt and I am sure I put it on correctly. So that was in early Dec and I have been using the saw since then, on Tues night (or wed morn) I turned on the saw for the tech’s and I started to smell burning rubber and stopped the saw, the belt had jumped the pully and started rubbing against the casting (opposite direct as previous).

?

Also note that this is a mechanical score machine

?

So now I think the tech reinstalled the scoring belt the first time and was installed correctly, idk maybe the belt jumping teeth twice is a red hearing and has nothing to do with the vibration but now I am even more suspicious, I brought it up with the tech’s and they didn’t seem think it was that interesting/relevant that it occurred twice.
