This is the first rewarding step to building your roto cast machine. The first steps are to drill holes in preparation for the threaded rods. You will need to drill a series of 4 holes on the 18x18 inch 1x1 frame, and 2 holes in the 16x16 inch frame. All the holes for the 18x18 frame should be drilled in the exact centers of each side.

Chronic hemodialysis only dates back to the 1940s. Before there was dialysis, chronic kidney disease was fatal. With the advent of the Kolff Rotating Drum dialysis machine in 1943, a new era of treatment for kidney failure began—which has saved hundreds of thousands of lives. Here, we share a brief history of dialysis from its start to the present.
