Like the Meaderses' treadle wheels, the glaze mill was partly the<br />

handiwork of a local blacksmith (fig. 28). A three-quarter inch shaft<br />

penetrated the bottom stone and was received by an iron cross, or<br />

spider, laid into a chiseled-out space on the underside of the runner<br />

(fig. 29). The space between the two stones could be increased or<br />

decreased by adjusting a lower support on which the base of the shaft<br />

rested.<br />
