The length of these rails allows a maximum turning length of about 15". I didn't work this out ahead of time - it was just a couple lengths of oak that were available. If and when I ever need to turn something longer, I'll just have to build something bigger.
At the other end of the rails is a 1" thick piece of poplar that is screwed in place and this keeps the rails spaced 1" apart along their whole length.

The puppet, or tailstock, is a 17" x 2 13/16" x 2 1/2" thick glue-up of redwood. Its 1" thick tenon that fits snugly between the rails is 6 1/2" long.

|The upper pencil line is the location of the bottom edge of the rails.|
The lower line is angled for wedging and is 1/16" further from the upper line at front than it is at the back.
This 1" wide mortise is cut into the 2 1/2" wide tenon, but it's not centered. Rather it's placed more forward so that there is more tenon shoulder behind the mortise than there is forward of the mortise. This will help to resist the backward force of holding the turning work between centers.
The center is another 3/8" lag screw and it's location was not measured, but determined by putting the puppet in place, sliding it up to the headstock and butting it up against the headstock's point to provide an exact location.

The tool rest has a base and an upright. The base is 7 3/4" x 2 1/2" x 3/4" red oak, slotted for the 1/4-20 bolt that would hold it to the rails. The head of the bolt is housed in a wider slot that is sized so that the bolt head won't turn when tightening the nut.

The nut that tightens the toolrest to the rails is a 2 1/2" x 2 1/2" x 3/4" piece of red oak that is tapped for the 1/4-20 thread of the bolt.

With the exception of the hinges, this lathe was built from materials I had on hand. So total cost was about $5. Well, that's all I can think of. If anyone has questions, please ask. Next time I'll show some of my first turnings.
