A setting in stick is used, usually with a mallet, to set in folds or angles in sheet lead. Once you have marked out your lead and made folds using a dressing stick (as shown on How to use a lead dressing stick), you are ready to sharpen these bends using a setting in stick. This process is usually as part of the installation of chimney flashing, although can be implemented in a range of other lead working applications.
Using a setting-in stick to sharpen folds in sheet lead
Place your setting-in stick against the inside edge of the corner. With a mallet, hit the tool to drive the sheet lead into the creases of the lead to reinforce the folds.
Using a setting-in stick to finish lead flashing
A setting-in stick or a lead dresser may also be used in the finishing of lead weatherings to help secure it in place in the mortar of a chimney. The tool is used in a similar way to a chase wedge. With the flat face of the setting-in stick, simply strike the lead along the edge of the flashing and force it into position.
