Wood workshop

There are a great number of joinery methods.

- dovetail joints
- splined joints
- mortise and tenon
- wood dowels
- wood biscuits
- nails
- screws
- specialty fasteners
- glue
- combinations of the above.

MDF or Medium Density Fiberboard (not to be confused with OSB or Particleboard) is essentially a composite wood which is created by taking the remnants (wood fibers) from cutting traditional wood stock down and combining it - usually - with a wax/resin binder to create hard and durable sheet panels (usually 4x8). MDF may be used instead of plywood or chipboard. It is dense, flat, stiff, has no knots and is easily machined. It is made up of fine particles and therefore does not have an easily recognisable surface grain.

MDF can be painted to produce a smooth quality surface. Because MDF has no grain it can be cut, drilled, machined and filed without damaging the surface. MDF may be dowelled together and traditional woodwork joints may even be cut. MDF may be glued together with PVA wood glue. Oil, water-based paints and varnishes may be used on MDF. Veneers and laminates may also be used to finish MDF.
