This listing is for an aluminum taig style lathe bedway. The dovetail is aluminum as well as the U channel. The dovetail is held on with 1/4-20 countersink bolts.

I used 3d printed inserts to add dead weight. Also used 1/2 inch aluminum standoffs to bolt the dovetail on. They are drilled through and tapped for 1/4-20 bolts to attach the feet. The feet are not included.
