The use of the Freeing Tool in removing the cell cover cuts away a certain amount of metal from the diameter of the posts. Before these posts can be relocked by the Peening Tool in replacing the cell cover they must be built up in size or diameter again so that there will be enough lead to insure a tight joint.

To Rebuild Posts

Thoroughly clean the post. Place the proper Post Re-Builder so that it rests on the shoulder of the post, and run in enough new lead to fill the Re-Builder. Fig. 251. Be sure and bring the lead surface of the post into fusion before the new lead is run in, to insure a strong post.

To build a smooth, solid post, be sure that the post is thoroughly clean; then use a hot flame.

To Lock or Peen Posts

(1) Assemble positive and negative groups without separators, and paint the posts (just above the shoulder) with hot sealing compound.

(2) Prepare the cell covers by immersing them in hot water until they are flexible.

(3) Place a warmed cover over the posts of the two assembled groups (the elements). Fig. 252.
