The Bed Alignment System for the Opus1
Aligning the bed in the Opus1 is an independent adjustment, unlike other designs. If the bed ever needs to be adjusted because is becomes not parallel to the main rod for any reason, you will find this procedure much easier than with older machines.
This bed is pinned on the left side and rotates around that fixed position. You will notice that there are set screws on the base behind the bed only on the right side. The brass screw is threaded in the bed and the zinc screw is threaded in the adjustment bar attached to the bed. The brass screw PULLS the bed and the zinc screw PUSHES the bed. The bed is locked under the base as in other machines.
The alignment is ONLY modified to make the BED parallel to the MAIN ROD of the gouger. If the BED is not parallel, the gouge will not be centered with the piece of cane. It will actually be cut into the cane diagonally. In this situation, the thickness of the sides of the piece of shaped cane will not be symmetrical and the reed would have serious problems.
There are two good tests to determine if the bed is parallel to the main rod:
Measuring the "Four Corners of the Cane"
Bending the gouged piece of cane over your finger to see how it folds
