The fabrication is 100% quality work. This part will be the pinnacle for my upcoming build as the solid construction, the sealed bearings and precise measurements are exactly the type of quality that would be expected for a mechanism in its position. The only slight disappointment was the outer teeth do not mesh with Lego chain due to the teeth being the full width of the table, an issue that any enthusiast can get around. To make this item perfect, I would remove only the necessary width to allow a chain to embrace this beautiful gear.
