    Casting A Mold Rammer

    I dabbled in casting back in the 80's when D. Gingery first came out with his books on the subject. I still had a wood mold rammer kicking around from back then but it was too large a diameter at 31/2" and hard to get into tight spots. I reduced the diameter to 21/2" and cast it in aluminum.

    Here the rammer has been sliced in half and alignment pins and matching register holes installed.

    Two coats of durathane to seal it and its ready for the mold flask.

    And the results after a good power wire brushing and some filling to blend some rough spots. I poured to slow entraining some gas and I didn,t flux but very acceptable. It has nice weight and is a big improvement over the old rammer.
