Gypsum Mouldings: Creating the Moulding Form

A moulding is a strip of material, often wood or plaster, with various profiles used to cover transitions between surfaces or for decoration.
The following describes the creation of moulding form:

 A metal sheet will be cut to create moulding.

 Draw the profile of the desired mould on paper and tape the paper to the metal plate.  In this case, the moulding is 60mm x 30mm, and modeled after the classical moulding Cyma Reversa.

 

 Using a jigsaw, cut out the form of the moulding

 

 Cut metal sheet

 file the edges of the metal sheet to prevent injury and to eliminate any spurs that might streak the moulding.

 Trace the moulding on a block of wood

 Draw an additional line 5mm outside the line of the moulding design.

 Cut out the moulding at an angle.

 Sand the wood with sandpaper

 Punch holes in the plate and attache with nails.

 Moulding form

 Attach the moulding form to an anchoring board.

Ensure the moulding form and anchoring board are perpendicular.

Attach diagonal bracing to maintain 90 degrees
