The next part cast was the baseplate. I needed to modify my larger flask by adding corners because I didn't have enough greensand. The pattern used 3/16 plastic lettering purchased from a plastic model supply site. Swept a compass across the painted surface and estimated the spacing first. Then laid it out with tweezers and finally glued in place one letter at a time with white glue. I am glad I waited until I had painted and smoothed the wood patterns as these letters don't stick up that much. I waxed and buffed to help pull the letters from the sand. The Esses are a little messy, but its legible. I always admired how other people did this on their models. It adds a lot of realism in my opinion.
I gated into the bottom surface so the tapered edge would be preserved, and placed 1/2 & 3/4 copper risers on the two thickest bodies to compensate for shrinkage. I barely had enough in the crucible (lucky). I will definitely need my larger ones for the next two parts, the Flywheel and Cylinder. There are some indications on the cylinder mounting pad that I hope are superficial.![Confused face :confused: 😕](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f615.png)
