Horsing Up

These are a few images of the parts of a plaster running mold that I made as part of a class project at the American College of the Building Arts in Charleston, South Carolina.  A running mold consists of a profile (knife), stock, horse, brace, angle rule, and core knife.



Tuck-Pointing

When re-pointing historic bricks, it is important to match the new mortar with the old.  Hand molded bricks are generally fairly soft and porous, so lime is the mortar of choice. Pointing with a mortar that is harder than the original will cause pressure to be relieved through the masonry itself rather than the joint.
