I have a DW733 planer with a Wixey DRO on it. I noticed that when running boards through, the measurement on the Wixey increases by about 0.02" as the board passes through. Once the board is through, I can release the head lock, and the cutter unit noticably moves downward, and the Wixey display goes back to the original value.
Somehow, the cutter unit is moving "up". By wedging a board between the table and cutter unit (powered off), I could easily move the unit up and down a little bit.
I think I determined the problem to be in the threaded rods that raise and lower the planer. They have a groove cut in them which rests in a piece of metal which is screwed to the chassis. This allows the threaded rods to turn, but not move in the vertical direction. On my planer (which is WELL used), the slot in the rod has clearly worn against the piece of metal enough that it is nearly twice as wide as it should be.
I think I can fix this by replacing both threaded rods with new ones.
Questions:
1) Has anyone else had this problem?
2) What do you think about that design? It seems like the rod rubbing against the piece of metal would be bound to create this problem.
3) Since I'm ordering parts, is there anything else that should be replaced/inspected?
