    Apron

    The Carriage

    Cleaning the Apron and Carriage came somewhat later in my process after I was able to clear some room. For those not familiar with lathes, the terminology can be confusing. Ultimately, the point of the carriage is to position a cutter relative to the work and enable the cutting to take place. work. It moves on the bed via gearing. The carriage consists of several components: the part that moves back and forth on the bed is the saddle. On top of the saddle is the cross-slide. On top of the cross-slide is the compound which enables other positional movements of the cutter. On the side of the carriage is framework that hangs down in the front. This is called the apron.

    Here is the saddle upside down with the apron still attached. The cross-slide and the compound have already been removed. It has been cleaned to a degree, but not fully disassembled.

    Here is the other side of it with all the components still attached. It's upside down by the way.

    Here is a picture of the inside of the apron, more fully broken down. The circular structure in the upper picture is the backside of the knob which controls engagement of the carriage with the leadscrew.

    Here is the top of the cross-slide. As you can see, it was in pretty good shape to begin with.

    Here is the apron fully cleaned. At first, I did not remove the knob, because it seemed pretty stuck. Later on, I realized there was a left-handed screw in there.

    One detail that I found interesting is a channel for oiling. On the front of the apron are several holes for oil. Here is the backside of the hole. The oil simply runs in a little trough and down into the gearing.
