the exposed surface twice, or at most three times. Then 

 change the relative position of the strips, placing 1 where 

 2 was. The pith sides which were in contact will now 

 be exposed, and the surfaces you planed before will be 

 in contact. Take off two or three shavings, and then 

 return the strips to their original position, and repeat. 

 Continue this until the taper and size are very nearly but 

 not quite reached. 



Both pairs having been thus treated, melt some fresh 

 glue, closely following therein the directions in the Chap- 

 ter on Repairs. The glue you so prepare you may re-melt 

 for future use three times, and not more. Then wash 

 your glue-pot out clean, and the next time start fresh. 

 Glass or china makes the best glue-pot, but any small tin 

 vessel an old spice-box for example will answer till 

 the tin rusts through. In the latter case solder on three 

 copper - wire legs about one - third of an inch long, and 

 punch a couple of holes near the rim that you may attach 

 a wire handle, like that usually used on pails. To suc- 

 ceed with glue, not only must it be fresh, but in melting 

 it must not be heated above the boiling-point of water. 

 Merely placing the glue-pot in another vessel containing 

 water, and applying heat to the latter is not sufficient 

 to insure this, since the heat may be conducted directly 

 through the bottom of one to the bottom of the other. 

 In the neglect of these seemingly trifling precautions will 

 be found the reason why a violin-maker will unite to last 

 for centuries the many parts of his complicated struct- 

 ure, and this with glue alone, and without a single nail 

 or screw, while another cannot thus join anything to 

 hold even for a few days. Therefore do not fail to raise 

 your glue-pot above the bottom of your water-bath, so 

 the fluid may surround it on all sides.
