Model W1729 (For Machines Mfd. Since 1/12)
Blade.Speeds
There are three factors in determining which blade
speed to use: the type of blade, the material being cut,
and the feed rate at which the material will be cut.
Harder wood should be cut at a slower speed with a fine
blade if a smooth finish is desired. On the other hand, a
coarse blade at a faster speed will clear sawdust more
effectively, but leaves a rougher finish.
The FPM pulley ratio diagram on Figure.29 illustrates
the belt positions necessary to produce the 1,700 and
3,500 FPM blade speeds select the proper pulley ratio
for the cutting job and move the belt to the desired
pulleys.
