Comments:

This mill lived much of its life is eastern Connecticut in a home hobby shop. It was sold off with a few other machines in an estate sale in July of 2026 after the owner died. I purchased it from the gentleman who purchased all the equipment. It was is "fair" cosmetic condition. All bare surfaces were newly rusted and had significant rodent sign. Seller was motivated and I purchased the mill disassembled but complete with a small amount of tooling and a mill vice. Completed full tear down and cleaning. Spindale runout is under .002, X-Axis is .002" Y-axis is .006 but correctable. Complete repaint completed, Starting DRO install next. Before and after photos attached.
