CHECKING THE SADDLE TO BED FIT
With the screw adjusted to the bed as before, the tail end will be worked on next.
Note the small clearance of the nut along the bed axis ( I said it was tight! ) in figure14.
The fit of the carriage is again checked and all is well, parallel, perpendicular, and size shims can be used an even shim can be used. The back of bed was cleaned up and the surface checked for square before making a back mounting block. Fortunately no machining or scraping was required.
See figure 15.
