Greetings all, My boss went to an auction and bought a few pallets of useful machine shop stuff. On one of the pallets was an old beat up Rusnok mill. After sitting in the corner collecting dust for a few years, the boss man needed some space and the little Rooski ended up in the bed of my pick-up. Stoked, I took the little feller home and gave it a bath. It was dirty but in decent shape, the only problem I found were the gibs worked their way loose and got hammered. The y axis gib was bent up into a U shape and the x was bent in several places. I straightened them as best I could, but the critters need to be replaced. The gibs are just .116 x .344 flat bars of ??? cut to length with 1/8 holes drilled about inches from one end. If I can't get parts from Electro Mechano, would anyone hazard to guess what type of material these might be made out of?
