The next step for the excavator sign will be to sculpt some extra details using a two part sculpting epoxy. Once the sculpt is mixed it slowly starts to harden. Dan quickly filled in the screw holes and then added the front and back cab window frames. Then, he pressed on the “rocks” onto the dirt pile using little balls of sculpting epoxy.
Since this is an indoor sample sign, Dan used wooden dowels for the hydraulic lines. A few pieces of 1/8"metal rod were bent to shape and glued in place for the hydraulic hoses. Some bits of an old plastic face shield were cut to shape and pressed into service for the mechanical linkage on the bucket. A piece of 3/18" steel rod formed the exhaust pipe. Then he whipped on a coat of texture primer. The sign is now ready for paint.
