Here in the UK we use the term’ oddside’ moulding. The moulder would place the pattern onto the moulding board. The pattern would be dusted and then covered in a good layer of Virgin sand. Firmly packed and then backed out with backing sand. The box would then be fully rammed up and strickled off to finish. Upon turning the box over the pattern is located and dug down to. All the edges located and the split line found. The moulder would then smooth down the surfaces ready for preparing the Cope. At this point this box would be used several times to make multiple pieces. A fresh Drag being made each time.
The use of split patterns greatly reduces the time spent moulding and should reduce the cost of the finished product.
