Re: Mysterious shift in saw alignment

 

Mark, can you take some photographs.??
From what I understand from your description, there is enough movement in the slip joint between the pivot arm casting (yr #121) and the sawframe that the blade is nearly hitting the RHS of the slot and still the sawframe is fouling the base to the extent it doesn't complete the cut?? Definitely weird.? (if there wasn't enough movement you can file more clearance into the slots in #121, something I've routinely done on the saws I've adjusted.
Would seem to me its hanging up somewhere other than the switch, and it's real difficult to see between the sawframe and the base at the best of times.
Try draping a sheet of plastic or a cloth over the base and then lowering the sawframe.? Pull the sheet to see where it hangs up. Maybe there's?more than one pinch point - jv

Loosening the M10 screws on the support bracket, part #121, and pushing the sawframe over as far as it could go -- to the point where the blade was close to hitting the outfeed support nearest the front of the saw -- still did not permit the sawframe to drop down much more.? Pretty strange.

The only way I could get the blade to get anywhere near parallel to the outfeed "gap" was to place a .010" shim between the back of the support and sawframe.? Tightening the rear M10 bolt without it invariably caused the sawframe's horizontal alignment to rotate counter-clockwise (looking down at it), resulting in significant misalignment relative to the outfeed support.? This is after loosening both bolts, so it's impossible to say just how much the saw had been messed with at the factory to get it to cut anywhere close to square.? That's one of the frustrating aspects of these saws.

I had wondered if the pivot shaft had somehow bent, but I loosened the grub screw on the left side and rotated the shaft about 90 degrees and re-checked the alignment.? No change.

The pivot shaft can't move to the left or right because it's got a spring pin on the right of the bearing ears (preventing motion to the left), and it's captured by the grub screw on the left side, which would prevent motion to the right (due to the bearing ears on the left side).

Still baffled by what's going on....
