Can you read an AutoCAD .dwg or .dxf? My drawing is a bit chaotic but it's al there if you look hard enough. I draw to get the dimensions then draw individual pieces for cutting.

I have lots of 12mm Belleville washers left, the minimum order was generous. I can send you half a dozen for the three screws if you PM an address, may take a while to find them though. I may have some 16mm I used for the ballnuts, spec is at www.bellevillesprings.com
