Here are some pics of the carriage assembly. I don't have the tool post in these pictures'cause I just didn't feel like finishing it yet. And I'm considering the lead screw

mechanism (including the apron) a separate section so that's not in this picture series

either.

0s soon as you finish the carriage assemblyprogress really picks up speed. Atthis point most of the hard and tedious work is done. This page is on the finished

leadscrew assembly. The leadscrew moves the carriage assembly along the waysside to side. All I have to do now is build the countershaft (motor mount) and the

lathe will be able to start cutting and turning (to bore the headstock pattern)! The

head and tail stock and faceplate patterns are the only ones left to build. Thank

goodness...
