Had to slice up two blocks to produce enough material to re-composite to the required car width. In retrospect, some of the layers could have been 1/4” or 1/2” thick, but I had already cut it all into 1/8” slices and figured out the settings for laser cutting to that depth in pine. I cut other 1/8” thick scrap materials for bed placement trial and error.
I was thinking that next time it would be fun to try a vertically stacked design vs. a laterally stacked one, or start with a solid car base and build a slot -assembly , thin walled body on top.
