Yesterday i set my Rubi up to cut some travertine 300x600. When cutting along the 600mm length, just about on the last 150mm cut the blade would wobble and the cut would veer off line resulting in an unnacceptable cut. This happened every time during the day. If i cut the width of the tile i had no problems...only along the length.
I checked everything i could check, wheel in good condition (hasnt done many cuts) Its not warped as it cuts fine the 1st 3 parts of the tile. The bed of the machine was clean and flat. I checked the overhead rail to see if that was twisted, No it was fine. I looked at the bearing wheels that run in the overhead rail and they looked fine.
The only way i could cut a straight line was to mark the tile along its length and watch the wheel as it cut and made any adjustments if i saw it veer off line. Obviously this isnt right !
Then today i got to work and prepared to cut more tiles....Perfect! not one tile cut badly.... What gives here? I made no adjustments and now it cuts fine.
The only thing i can find now is, if you hold the black handle by the motor to pull the wheel through the tile and twist yoour wrist. This will make the whole motor assembly inc the cutting wheel move 10mm either way. What i could do with is finding someone who has the same machine and comparing tolerances.
Any thoughts ??
