Had a Modeler over on the other forum that experienced a broken side rod on his K27, probably due to a counterweight that got loose and had fallen off, Jamming the mechanism and breaking this rod. i will soon have this part available on Shapways for Purchase in Brass for less than $25.00 plus shipping.
i should note that the ability to do this in brass @ shapeways was the overall part size. the main rods i did in the past were beyond there capability, and had to do in other metals.
