Cupboard doors made of MDF
The shaping of MDF doors is usually done with a routing machine, either a hand held router or a computer controlled router. Vacuum extractors must be used to remove the very fine MDF dust produced by the high-speed cutting action of the router cutter.
a) Draw a typical hand held routing machine.
b) Draw typical shapes of some router cutters.
c) Show typical routed profiles produced by these cutters.
d) Use notes and sketches to illustrate how a hand held routing machine could be guided to produce rounded edges on a kitchen cupboard door.
e) Use notes and sketches to illustrate how a hand held routing machine could be guided to produce a recessed design that imitates a frame and panel construction door.
f) Spring hinges used on kitchen cupboard doors are usually fixed in 35mm diameter holes. These holes are drilled using a Forstner bit. Draw a Forstner bit and explain what is special about it.
g) Use notes and sketches to illustrate how you could accurately drill a hole 12mm deep in an 18mm thick piece of
MDF.
h) Describe how an MDF kitchen cupboard door could be finished so that it would have a shiny white surface.
i) Describe how an MDF kitchen cupboard door could be finished so that it would have a textured white surface.
j) Describe how an MDF kitchen cupboard door could be finished so that it would have a rich mahogany look surface.
k) Use notes and sketches to illustrate two possible ways that door pulls could be fitted to the cupboard door.
Extension work
