187. ' 'T"-Weld. The center of one piece and the end of 

 the other must be upset, as shown in Fig. 209. Fig. 210 and 

 Fig. 211 show how these pieces must be swaged to form the 

 welded joint. A difference of 1/8" between the thickness of

stock and the upset portions of stock will be sufficient to form 

 the welded joint to the thickness of stock, as shown in Fig.

188. Wagon Wrench. The preliminary steps of heat- 

 ing and upsetting the two pieces of stock for this project are 



similar to those already de- 

 scribed. A little more diffi- 

 culty may be experienced be- 

 cause of the dimensions of the 

 stock and the lengths of the 

 upset portions of same. When 

 the rectangular stock is fully upset, it must be laid flat on the 

 face of the anvil and pounded on the upper surface near each 

 end to flatten the lower surface (Fig. 212). This will make 

 the additional thickness of the upset portion of the stock off- 

 set on the top surface. Heat this part of the stock and 

 make a groove 1/4" deep with a 5/8" fuller (Fig. 213). 



The remaining exercises involved in making this project 

 should be clear by a study of Figs. 214, 215 and 207. Mark 

 the points where the bends are to be made on the rectangular
