Vertical Boring Mill Capacity Is Increased 
-	
-..--
A commercially available vertical boring mill with a 
nominal capacity to 27 feet in diameter of workpiece 
has been modified in-shop to handle work up to 36 
feet in diameter. Close schedule demands did not 
permit the order, manufacture, and delivery of a new 
larger machine so that this modification proved a firm 
requirement.
Capacity was increased by adding extension saddles 
to the mill support columns on each side. The photo 
above shows the vertical boring mill in its original 
configuration and it is shown overleaf after modifica-
tion.
