Thanks for the comment,I agree with your observation regarding the design of the Cope and Drag I intend to work on the problem.We have had good results with several split patterns using these boxes,however I can see that using cores will make handling the Cope difficult.

Can you give me any advice on the best ingredients for core mixes?We now have a considerable student interest in sand casting and we need to keep it simple.

Thanks again

the design of the cope and drag is amazing, i love how u did the triangles on the side

@googleisgod1 Fantastic set of videos. Cope and Drags look well made. However, the V-alignment blocks would only be any good for flat back patterns. When split patterns are involved, especially those involving cores already placed in the drag, proper vertical descent of the cope is needed long before the cope and drag meet each other. This cannot be achieved with the V-alignment blocks.
