Trying to fix a Morso chopper that does not seem to cut the notch exactly square with the table guides.
When I cut a mitre with the wings in the normal position, the length of the diagonal cut on a piece of 3” moulding under my right hand is about 1/32 longer than the piece under my left hand.
Also, to get a perfect 90 degree corner I have to swing the left wing about ½ degree towards me. The angle of the joined cuts is correct but the moulding pieces don't match up visually.
Also, as I make a cut I can feel the piece under my left hand moving slightly away from the blade, even with newly sharpened blades. The motion is less than 1/100 inch, but enough to feel.
I checked the vertical accuracy of the blade motion with a machinist's tool and it's perfect.
The table guides seem to be correct and true with the factor registration pins. If I run an accurate straight edge across the wings and along the guides, everything lines up. If I grab the chopper head itself I can't feel any play. Everything is correctly lubed. I get the same problem with both old and new blade sets.
So one or more things are out of alignment. If I could rotate the table and guides about ½ degree relative to the blades, I think the problem might be fixed. Is there a procedure to do this? But I suspect there's some more basic problem.
The table guides seem to be correct and true with the factory registration pins. If I run an accurate straight edge across the wings and along the guides, everything seems to lines up. If I grab the chopper head itself I can't feel any play. Everything is correctly lubed.
Does this sound familiar to anyone? It's kinda baffling. Would appreciate your input, thanks.
