One of the engine mounts started to look like the apron of a lathe, so after a few plasma cuts and grindings, it is.
|

Finally ground down the rough edges for the lathe table.

|

setup for roughly turning the chuck circular, a grinder was held by hand and the device rotated by hand.
|

This shows the homemade bolts for adjusting the jaws, and the round hole drilled
in the center. I'll be making a punch for turning these holes square.
|

Finally realized I had an airhammer errr make that air precision metal file ;-)
|

The base is assembled
|

Bent rebar and buildups for bolt nut threads.
|

First attempt at putting in bolt threads, failed, welded bits too hard in spots, broke drillbit, had to cut out large section..
|

Finished, more or less.
|

tail is too long, but I'm going to wait to see where I should cut it off.
