The modern breed of CNC metal cutting machines makes custom part fabrication approachable for just about everyone. This family specializes in water-jet milling, and can accept DFX files in native format. I sent them a drawing on Wednesday, and was told that the parts for my mast tabernacle are ready today. They ship all over the world and their prices are very reasonable, with fast accurate quotes. Total cost for cutting all parts for a reasonably complex piece was $165 USD including stock. http://www.mainlymetals.com/
