Acoustic Guitar Form - OM (Orchestra Model) size with a Squared off Cutaway for Luthiers and Guitar Builders
An MDF guitar form (also called a mould or mold) for Luthiers and acoustic guitar makers for shaping guitar sides after steam bending and/or holding the sides while completing the work.
This is an 'OM' size with a Squared off style cutaway shape.
With 5 layers of 12mm MDF, this is a perfect depth of 60mm and allows enough room for attaching bindings.
A custom designed hinge system holds the two halves together with a 6mm aluminium pin and locks the form tight as a single piece. Easily knock a pin out with a pin punch (or a 5mm bar or screw driver) to separate the halves to remove the moulded sides.
Cut to size with a CNC and laminated with Titebond glue, the inner and outer forms have a 3mm gap to allow space for the bent sides to fit perfectly. Flats machined onto each end allows the form to be stood upright on a bench and flats machined on the inner form allow positions to easily place clamps.
Shown as a right hand model, but turned upside down, a lefty can be made.
A complete system, this comes with the outer forms, the inner forms and 2 pins for locking the halves together.
