Pewter Casting Project Flashcards
Heat proof gloves
To protect hands from molten pewter
Workshop Apron
Protect yourself against pewter splashes
Fire Brick + Heat Proof Mat
Ensuring that your area is protected, doesn’t burn the tables
Blow Torch
gas powered blow torch to heat the pewter in the ladle
Safety Goggles
making sure eyes are protected
casting block + MDF Plate
plate slides between the two blocks. Pewter melts at 200.c
Ladle
Used to pour the melted pewter
Engineers vice
Used to hold work, has teeth so work must be held between a tissue
junior Hacksaw
Just a smaller version of the hacksaw. Used to cut of the sprue from your work
Needle Files
Smaller versions of hand files, used to sand away the big cracks
Dremel
Used to polish work or add textures
Wet and Dry Paper
Used to sand down work. Comes in various grades, higher the grade the less abrasive it is
What is pewter made of. (Give 3)

How does modern pewter differ from older pewter
In 18th century, pewter was made of tin and a small bit of lead to harden it, now a new alloy was discovered called Britannia metal
What propitious does pewter have, e.g colour and melting point
Very low melting point at 175 degrees.
silver colour
When was pewter first introduced
Egyptian times
What has pewter been used for traditionally
Tankards
Give four examples of the advantages of CAD
Operator error is limited
High accurate drawings are produced
3D viewing allows different angles of positions
Designs can be transmitted quickly via the internet
Easy and quick to edit designs
Designs can be stored on disks
Give 3 disadvantages of CAD
Understanding the applications is time consuming
CAD is unsuitable for the initial stages of designing
Setup costs high due to computes, printers, training
Give 3 advantages of CAM
Machines don’t need food, water, light, toilets, company
Machines don’t get tired
Replacing workers with machines will reduce cost
Give 3 disadvantages of CAM
CAM machines will keep making same mistake if programmed wrong
High set up cost
Replacing workers with machines will increase unemployment
