The first part of the lead screw assembly is the
apron. This is a pretty simple part as it is only a rectangular casting.
In this view you can see that I have already drilled the hole for the split nut
mechanism.

The lead screw is supported by some bearing blocks
on each end. I made mine as a one piece design and bored out the hole for
the bushing on a mill. I also made the bushing from solid stock on a lathe
rather than the pipe method Gingery describes. The gold colored pieces are
shaft collars that I bought at my local hardware store. |

Here is the other end with the handle attached.
I made the handle from a piece of 3" aluminum round and a cut-off bolt for the
handle. I need to make something a little bigger for this handle, as it
seems that this one is not quite large enough. |
