PLAN GRADING


Where possible, under each plan is a letter that indicates the type of plan. Some are taken from past issues of woodworker, some are full scale drawings and some need a little more interpretation.

A:-
Fully detailed with all dimensions. There are good construction notes, often on separate sheets. The plans are clearly drawn and measurements may be metric, imperial or both.

B:-
Level A but the detail may be a little more scant and not all joints are illustrated. Alternatively, all the detail may be on the plan but condensed into one or two sheets. Still for all levels of skill.

C:-
Plan reading ability/experience needed, with scale drawings. The main dimensions of all the elements should be given but you may have to work out the exact figures by adding and subtracting from the overall dimensions.

D:-
Significant parts need interpretation but all dimensions are still given but these may only be in the construction notes. Joint details often not shown and there may not be a separate cutting list.

E:-
Really for the fully experienced woodworker. These are sometimes only a single sheet with just one exploded isometric view. Key overall dimensions given.


F:-
May be an exploded isometric view but sometimes only a sketch and some dimensions have to be worked out.
