This picture is of our Golden Foundry #27
Sorghum mill. It is has six bearings that are oiled by wicks over each
bearing. Each wick-well originally had a cast iron cover but were all
missing. Five members of the Sweet Sorghum mailing list also have Golden
Foundry mills that were also missing the covers. Terry Hester's mill was
missing all but one cover and he was gracious enough to loan it out so that it
could be used as a pattern. Here is the process I used to duplicate the
covers.
The original cover that the pattern was modeled after.
I made a match plate out of wood that made enough lids for one
mill (6) with each pour.
Melting the aluminum.

My son Isaac adding scrap aluminum to the crucible.

Looking through the hole in the top of the furnace you can see the red hot heat.
|
|
|
|
It takes a lot of gas to fire the furnace. I kept haveing problems with the tanks freezing up.

The mold poured and waiting for the metal to
solidify.

|
The first couple of pour I had made rises over each lid.
|
|
|
|
|
On later pours I found I didn't need the extra risers and just used three over the main runner.

|
Opening the mold and knocking the sand off to
see how they turned out.

After pulling the cope and the drag apart the top of the lids come into view.
