The problem: 
To design an improved welding table for torch 
cutting of metal of various types and thicknesses. 
The solution: 
A 10-foot-square welding table is much improved 
when covered with parallel inverted 10-foot steel 
angles (½" by 4" by 4") centered about 9.25 inches
apart or as required. Surrounding them are box sides, 
tacked to the sides of the table, of the same height 
as the apexes of the angles (Fig. la). 
Pairs of short lengths of angle approximately 4 
inches long by Ye" by 4"—are welded together, apex 
to apex, to form X-sectioned "riders" (Fig. lb). 
These riders are placed astride the long angles (Fig.

Ia) and slid to their required locations. 
Very few riders are damaged when metal is cut 
on the table, and they can be replaced very 
cheaply—usually made from scrap. Clenup of the 
table is minimal; it need not be swept meticulously 
before subsequent work will sit dead-level on the 
surface.
