30 forum posts 11 photos | Hello all After retiring a couple of years ago I bought a Sieg SC3 lathe and a Sieg SX2P mill from Arc Euro, and am happy with both. My interest is in model stationary engines. The current project is the single cylinder balance beam engine designed by Gerry Dykstra, progress so far shown in photo (sorry I don't know how to rotate it). I am now making the crankshaft but can't find the distance for the throw. Scaling off the drawing (which as a former mechanical engineer I know you should never do!) comes out at 13mm centre to centre. Can anybody confirm this? Thanks GeoffT
