This taper attachment mounts quickly to the 

back bed way of your lathe. Accurate tapers of up 

to 12" can be produced without repositioning the 

attachment or having to offset the talstock. 

The Model SB1269 features scales at both ends, 

reading inches-per-foot and degrees. An angle 

adjusting knob with fine threads achieves 

exacting control when setting tapers. 

Another feature is the ability to use the taper 

attachment without disengaging the cross slide 

nut. This design allows the taper attachment to 

be functional at any time by simply tightening 

the two deadman-clamp cap screws, which lock 

the deadman-clamp to the rear lathe way.
