Stakes are used to form the metal sheets into various shapes. It is a sort of anvil, which supports the sheet for sheet metal work. It consists of a shank and a head or horn. The shank of stake is designed to fit into a tapered bench socket. The head or horn of stake is available in a number of varieties of sizes and shapes. Their working faces of stakes are machined or ground to needed shape. With the help of a hammer, operations such as bending, seaming or forming can be easily performed on these stakes. Some stakes are made of forged mild steel faced with cast steel. Whereas the better class stakes are made either of cast iron or cast steel. below shows the various types of stakes, which are discussed below:
- Beak horn stake. Beak horn (Fig.a) is basically used for forming, riveting
and seaming articles made of sheet metal part. It is not much suitable like blow
horn stake. It has a thick tapered horn at one end and a rectangularly shaped horn
at the other.
- Funnel stake. Funnel stake (Fig.b) is commonly used for planishing tapered
work and hand forming of funnels and similar conical shapes of sheet metal.
- Half moon stake. Half moon stake (Fig. c) is basically used for throwing up
edges of curved sheet metal work and for preliminary stages of wiring curved edges.
- Round bottom stake. Round bottom stake (Fig.d) is commonly used for
squaring up edges and setting up the bottom of cylindrical jobs made up of sheets.
- Bick iron. Bick iron stake (Fig. e) is mainly used for forming taper handles,
spouts and tubular work in general. The narrow flat anvil end of bick iron is very
useful on rectangular work.
- Hatchet stake. Hatchet stake (Fig. f) is generally used for making sharp
bends, bending edges and forming boxes and pans of sheet metal by hand. This
stake has a sharp straight edge beveled along one side.
- Creasing with horn stake. Creasing horn stake (Fig.g) has a round horn
used for forming conical shaped pieces in sheets. The other end has a tapering
square horn with grooved slots for wiring and beading.
- Needle case stake. Needle case stake (Fig. h) is generally used for bending
of sheets. It has a round slender horn for forming wire rings and tubes.
- Candle mold stake. Candle mold stake (Fig.i) has two horns for different tapers
when forming, seaming and riveting long flaring articles made up of sheet metal.
- Blow horn stake. Blow horn stake (Fig. j) is generally used in forming, riveting and seaming tapered articles such as funnels.
- Conductor stake. Conductor stake (Fig. k) has two cylindrical horns of different diameters. It is used for forming, riveting, and seaming small sized pipes andtubes.
- Double seaming stake. Double seaming stake (Fig.l) consists of two cylindrical horns of different diameters and it is commonly used for riveting forming, and seaming tubes and small pipes
