The Model SB1269 taper attachment was
designed to fit onto a series of South Bend
lathes. Shown in Figure 1, is a Model SB1012
lathe that is fitted with the Model SB1269 taper
attachment.

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.

The unpainted surfaces are coated with a heavy­duty rust preventative that prevents corrosion
during shipment and storage.

This rust preventative has been a close ally
and guardian since this item left the factory.
If the unpainted surfaces are free of rust, then
be thankful that the rust preventative did its
job...and try to stay thankful as you clean it off,
because it can be challenging to remove if you are
unprepared and impatient.

Plan on spending time cleaning and removing
the rust preventative. The time you spend doing
this will reward you with smooth sliding parts
and a better appreciation for the proper care of
the unpainted surfaces.

Although there are many ways to successfully
remove the rust preventative, these instructions
walk you through what works well for us.

Before cleaning, gather the following:

• DisposableRags

• Cleaner/degreaser

• Safetyglasses&disposablegloves

preventative. Before using these products,
though, test them on an unnoticeable area
of a painted area to make sure they will not
damage it.

Basic steps for removing rust preventative:

1. Put on safety glasses and disposable gloves.

2. Coatallsurfacesthathaverustpreventative

with a liberal amount of your cleaner or
degreaser and let them soak for few minutes.

3. Wipe off the surfaces. If your cleaner or
degreaser is effective, the rust preventative
will wipe off easily.

Note: To clean off thick coats of rust preventative

on flat surfaces, such as beds or tables, use

aPLASTICpaintscrapertoscrapeoffthe

majority of the coating before wiping it off

withyourrag.(Donotuseametalscraperor

4. RepeatSteps 2–3 as necessary until clean,
then coat all unpainted surfaces with a

products have low flash
points and can explode
or cause fire if used for

toxic if inhaled. Minimize
your risk by only using
these products in a well
ventilated area.

Avoid chlorine-based solvents, such as
acetone or brake parts cleaner that may
damage painted surfaces. Always follow the
manufacturer’s instructions when using any
type of cleaning product.
