tool and material storage space.<br />
Parts of patterns must be located together<br />
accurately. It is also necessary to provide<br />
accurate iocation <strong>for</strong> coreboxes and <strong>for</strong><br />
moulding hexes. For these purposes accurate<br />
bushes (sockets) and pins or dowels are<br />
needed. For the most accurate work these<br />
should be purchased from specialist manufacturers<br />
and made in hardened steel. Lwever,<br />
<strong>for</strong> less critical castings, simple metal<br />
location pegs and bushes may be made in<br />
pattern shops. The use of wooden location<br />
pegs is not recommended.<br />
A good supply of screws and bolts of different<br />
sizes is also necessary as is a good<br />
quality adhesive and a hard setting “filler”<br />
material.<br />
Pattern Storage<br />
If repeat casting orders are likely, patterns<br />
should be stored with care - especially since<br />
the pattern is often (depending upon the<br />
commercial arrangements) the property of<br />
the foundry’s customer. Wooden and metal<br />
patterns shou!d be kept on racks away from<br />
the foundry and the risks of accidental<br />
bruising or da.mage, fire hazards or damp.<br />
In designing a foundry, adequate space<br />
should be provided <strong>for</strong> pattern storage.<br />
