TIGHT COOPERAGE 



157 



On many of these operations, an estimate that 60 per cent of the staves 

 are sufficiently good for " wines " and 40 per cent for " oils " is made. 

 The former bring about $50 per thousand and the latter $25 per thousand. 

 The selling price runs, therefore, about $40 per thousand staves, leaving 

 a profit of from $7.00 to $12.00 on each thousand staves marketed.

Heading mills are operated along the same lines as described for tight 

 staves, and the stock is always sawed in i-in. thicknesses from bolts cut 

 about 2 in. longer than the diameter of the finished heading. The 

 machines commonly used in these small portable heading mills are a 

 heading bolter, a heading saw, a heading jointer and doweler, a heading 

 planer and a heading rounder together with a baler or baling press.
