Ferndale’s Lathe Chuck Shield

This is Ferndale Safety’s most popular lathe chuck shield.  People love this guard because it’s lightweight and available in many different sizes.  You will be able to install it on your older conventional lathe such as that old Monarch or Lodge & Shipley that still works like a boss.


This lathe chuck shield includes a built-in electrical safety interlock switch.  Connect it to your motor control and you will never forget your chuck key inside the chuck again.  The wiring is there – it is up to you if you want to connect it, but we highly recommend that you do.

You can change out your own shield:

You will love how easy it is to replace a worn out shield.  Pop out the used shield from this guard by removing the blue clips.  You can purchase replacement shields from us, or cut your own from a sheet of polycarbonate and slide it in the steel frame.  Simple as that.

What Screen Size is Best For Me?

To find what screen size you need for this lathe chuck shield:  Take down the diameter of the largest chuck you use on your lathe. Multiply the diameter you measured by 1.5 and choose the screen size in A that is closest to your answer. Using this formula will guarantee that you will have room under the guard even though the jaws are open beyond the diameter of the chuck.

If your chuck is measured to be 12″ in diameter by 6″ in width:  Multiply 12″ by 1.5 and you get a result of 18″. The closest measurement for the A dimension to your result of 18″ is 17 3/4″. Select 17 3/4″ from the “A” dimension drop down box above.  Select 7″ from the “B” dimension drop down box as it’s the closest to the width you measured.

Easy Installation

Two bolt installation:

Most of the time, you can drill and tap two holes directly into the headstock of your lathe.  On odd occassions, you might need to make some custom made brackets.  We use aluminum angle stock which is easy to work with and cut.  If you need any advice or help installing these lathe chuck shields, please contact us and we will be more than happy to help you out.

Why You Need This

The lathe chuck needs to be guarded because:

The jaws can extend beyond the diameter of the actual chuck and can create an entanglement hazard.  These jaws could act as hooks, ready to grab onto anything more easily than a smooth shaft.


These shields prevent you from leaving the chuck key inside the chuck.

Here’s how:

This lathe chuck shield comes standard with an electrical safety interlock switch that can be tied to the spindle motor.

Don’t forget:

The most common accident on a lathe is due to the chuck key flying across the room.

For this reason alone, we highly recommend installing this lathe chuck shield.
