First crack at the core using the instructions from Dave Gingery's building a lathe from scrap series. Very fine sand, 20 Table Spoons plus 2 Table Spoons white flour; shaken, not stirred Mr. Bond. Then 10:1 ratio Molasses and water added a little at a time and worked with a spoon. Was thinking a miniature sand muller would be great for this. Kept adding liquid until it was a slightly damp version of green sand with a bit of strength. Packed into the core box as tight as I could without any re-enforcement wires. Flipped over onto the aluminum plate and the box carefully separated. Next placed in small table top oven at 350F for 1 hour. Came out hard. Yahoo. It will be flipped over and inserted into the green sand mold to roughly create the T-Slots once I make a couple more.
