squirt several
drops of machine oil inside the Tool, as well as putting some oil on
the top of the post, before forcing the hot Tool down over the post.
This will prevent the Tool from sticking to the post.

If the Peening Tool should stick to the post, force the Tool down
again, being certain that the cover is slightly compressed. Sticking
of the Peening Tool indicates either that the Tool has not yet been
broken in, or that there is not sufficient compression in the cover to
free the Tool on releasing the pressure on the lever of the Press.

To repair the 13/16" diameter straight terminal post, the Ford
positive terminal post, the Ford negative terminal post, it is good
practice to remove the cover in the usual manner, then cut the upper
portion of the posts off and rebuild them with the large Post
Re-Builder. Reassemble the element and cover in the recommended manner
and then use the proper Post Builder to burn the post to its original
size.

THE PHILADELPHIA DIAMOND GRID BATTERY

Old Type

[Fig. 254 Cross section of old type Philadelphia diamond grid
battery]

Figs. 254 and 255 show the construction of the old type Philadelphia
Diamond Grid. Battery. Figs. 254 and 256 show the diamond shaped grid
from which the battery derives its name. It is claimed that this
construction gives a very strong grid, holding the active materials
firmly in place, and giving a large amount of contact surface between
the grid and the active material.

Figs. 254 and 255 show the old type battery, and give the details of
the cover, terminal posts, vent plug, and so on. The post seal is made
tight by pouring the compound into the cover well so that it flows in
around all of the petticoats on the post.

This construction increases the distance that the acid must travel
along the post, in order to cause a leak, about two and one-half times
the vertical distance on a smooth post. The hard rubber washer which
fits around the post acts
