 Fill hole sized experimentally after original hole seized up too easily
+Only made one mold.  It warped after a few bricks due to difficulty cleaning it to make good seals
+====== Iron production ======
+Make 4 molds to ease cooling and other production
+Experiment with fluxing sides to make lead not stick
+Plan to semi-automate based on diagram: MDI / hand written g-code.  No CAM SW
+Reduce mold slats to minimum size?  Not sure how beneficial the extra was
+  * Think its main advantage was easy of machining: easier to grab
+  * Consider reducing slightly but not to min size
+  * Min: 6 + 2 * 0.125 = 6.25
+  * Cut to 7" to leave slightly over 0.5" each side to grip
