Today’s photos show the assembled harvest table rule joint in 3 different positions – leaf down, leaf half way up and leaf up. Proper routing of the joint and positioning of the hinges is necessary so that the finished joint is perfectly tight when the leaf is up but does not bind as the leaf is raised and lowered. Notice that as the leaf is lowered the leaf begins to move away from the edge of the table and when it is down there is good clearance between the leaf and the table edge.

Table leaf half way up. Clearance between leaf and table edge is decreasing:
Table leaf up. The closed joint is tight:
