In taking the welding lieat care must be exercised to pre\ent the eye 

 being Iiurnt. Cooling the eye occasionally will have the desired effect. 

 \\'hen properly heated, weld wdth the hand hammer. To obtain the best 

 results, start by striking light and quick blows on the thin edge of the 

 scarf and gradually increa.se the weight of blows as 

 the thicker part is hammered. It is desirable that 

 the welded portion should be left thicker than the 

 original bar for several reasons, one of which is that 

 it fits the hole tightly, and therefore prevents it from 

 turning round ; another reason is that it strengthens 

 what would otherwise be the weakest part. 



One welding heat should be quite sufficient to insure 

 satisfactory results ; in fact, much stronger than if 

 two or more heats are neexled to join the parts together. 

 It must be remembered that each welding heat wastes

 cases rendered useless. 



Cutting to length is the next operation ; then screwing to fit a nut. It 

 is always best to purchase nuts already screwed. It saves a lof of time
