Twisting. 

 Like bending, twisting can be performed 

 it a red heat without causing loss of strength. 

 I uisting is necessary in numerous cases ; for 

 'iistance, if a lians.cr, similar to that shown in 

 l-'ig. .^4, or a flat bar to be used as a stay 

 ( ^' 'g- 35)» requires to be made. 



Very little description is requisite to en- 

 able one to twist a bar of iron. If the bar be 

 flat like those illustrated, the position of the 

 twist should he marked with the centre punch, 

 heated and coolefl similarly to when making a 

 bend ; with the slight differenre that the length 

 of heated part requires to be equal to the 

 breadth of the bar. To twist round to the 

 flesired angle, one end may be held in the 

 vice or the fork-tool, and the other turned 

 around with a pair of tongs, or a dog; or two 

 pairs of tongs may be used, one on each end. 



Split Link.s. 

 A si)lit link is one of the m^ost useful 

 articles that the farmer requires. It also 

 aff. rds a good exercise for a beginner at 

 acksmitiiing. The best way to make one is 

 to cut off from a bar a piece of sufficient 

 length. Then point each end wedge-shaped, and afterwards bend each 

 end to a semicircular shape, as shown in Fig. 36Z' ; finally bend in the 

 centre. 



To find the length to cut off before working in the fire, add the thick- 

 ness of the iron to the inside breadth of the link and multiply the sum 

 by 3I. To the product add twice the difference bftwccn tlie inside 

 length and inside breadth. This 

 will give the neat measurement. 

 To this amount something will 

 need to be added to allow fori 

 wasting away in the fire, as 

 well as for imperfections in 

 working on the anvil. 



To attempt to fix this anioinit 

 definitely would be impossible, 

 becau.se a gofjd cpiirk workman 

 would not waste as much as a 

 sinw or careless one. Conse- 

 (luently the l)est advice that can 

 be given is : - Firstly, ascertain 

 the amount by calculation that 

 would be needed if no waste t<;ok 

 place and the workmanshij) were perfect ; secondly, follow the description 

 given as clasely as [)f»ssible ; thirdly, study the shajn' of the article. Hy 

 so doing the careful and observant man will find out what allowance- 

 suits his own re(]uirements. ;\ go(vl tra<lesman would onlv need to allow 

 about ith of an inch for a link made of \-'\\\. iinn.
