Wood lathe faceplate turning is a fantastic way to create larger, flat projects like bowls and platters. Mastering faceplate techniques means you can securely mount irregularly shaped workpieces for turning, unlocking a world of creative possibilities for your workshop.
Turning on a wood lathe is a rewarding craft, but sometimes the standard chuck just won’t cut it. When you need to work with large, flat pieces, especially those with unusual shapes, a faceplate becomes your best friend. It’s a sturdy disc that screws onto your lathe’s spindle and allows you to securely attach your wood. Don’t worry if it seems a bit daunting at first; with the right tips and a little practice, you’ll be turning impressive projects like bowls, platters, and decorative items in no time. This guide will walk you through everything you need to know to achieve success with wood lathe faceplate turning, ensuring safety and great results.
Let’s dive into making faceplate turning a breeze!
Why Use a Faceplate for Woodturning?
When you’re starting out with woodturning, you often get acquainted with the lathe chuck. It’s versatile for many projects, especially those that can be held by jaws. However, certain projects demand a different approach to secure mounting. This is where the faceplate shines. It’s not just an alternative; it’s often the only safe and effective way to hold specific types of wood for turning.
Consider the common woodworking projects you might want to tackle but struggle to grip with a standard chuck:
Large, flat bowls and platters: Items that are wider than they are deep, or have a significant flat surface, can be challenging to get a secure grip on with jaws.
Irregularly shaped blanks: If you’ve found a unique piece of wood with an interesting shape, a faceplate allows you to attach it without needing to cut it into a perfect circle beforehand.
Segmented turning projects: When building up a segmented bowl or similar item, you often need to attach the assembled blank to a faceplate for initial shaping.
Items with limited end grain access: Some pieces might not have enough end grain surface to get good jaw purchase with a chuck, or the wood might be too brittle.
Re-turning the back of a project: Once you’ve hollowed out the inside of a bowl, you often need to face significant material off the back to achieve a finished surface. A faceplate is ideal for this, allowing you to mount the bowl securely for that second stage of turning.
Using a faceplate provides a large, stable mounting surface. This stability is crucial for safety and for achieving consistent, clean cuts, especially when dealing with larger or heavier pieces of wood. It distributes the forces of rotation over a wider area, reducing the stress on the wood itself and on your lathe.
Choosing the Right Faceplate and Screws
Selecting the correct faceplate and screws is more than just grabbing the first ones you see. It’s about ensuring a secure connection that can withstand the forces of a spinning piece of wood.
Faceplate Types and Sizes
Faceplates come in various diameters and thread patterns. The key is to match the faceplate’s thread to your lathe’s spindle thread. Most lathe spindles have standard thread sizes, but it’s always best to check your lathe’s manual or measure the spindle.
Material: Most faceplates are made from cast iron or steel, ensuring durability.
Diameter: Choose a faceplate diameter that is appropriate for the size of the workpiece you intend to turn. A general rule is that the faceplate should be roughly one-third to one-half the diameter of the workpiece. However, for very large pieces, you might use a smaller faceplate and extend the reach with screws.
Thread Size: As mentioned, ensure the internal thread of the faceplate precisely matches the external thread of your lathe’s spindle. Common sizes include 1″ x 8 TPI or 3/4″ x 10 TPI, but smaller lathes might have different threading.
Screws: The Crucial Connectors
The screws that attach your wood to the faceplate are critical for safety. They need to be strong and sharp enough to bite securely into the wood without stripping.
Type: Use coarse-threaded wood screws. These cut their own threads into the wood, providing a strong hold. Cabinet screws or specific faceplate screws are often recommended. Avoid drywall screws; they are too brittle and can snap.
Length and Diameter: The screws should be long enough to penetrate the wood sufficiently for a solid grip, but not so long that they go all the way through if that’s not desired. The diameter should be substantial enough to resist shearing forces. For most faceplate work, screws of about #8 or #10 gauge, and 1 to 1.5 inches long, are suitable. Always err on the side of slightly stronger and longer if unsure. Always check that your chosen screws will clear your lathe’s tool rest.
Number of Screws: For stability and safety, use at least four screws, spaced as evenly as possible around the faceplate, at least 1.5 inches from the center. For larger or heavier pieces, consider using more screws or larger diameter screws. Research from reputable sources like the American Woodturning Association (AWTA) often suggests a minimum of four screws.
When in doubt about threads or screw types, consult your lathe manufacturer’s recommendations or visit a machine shop supply store for expert advice.
Preparing Your Wood Blank for Faceplate Mounting
Before you can even think about attaching a faceplate, your wood blank needs some preparation. Skipping these steps can lead to wobbly turns, unbalanced pieces, and potential safety hazards.
Rough Shaping the Blank
While the faceplate can hold irregular shapes, it’s beneficial to give your blank a bit of initial shaping. This isn’t about perfection, but about creating a reasonably balanced starting point.
Mark the Center: Find and clearly mark the center of your wood blank. This is crucial for accurate alignment with the faceplate.
Trim Edges: If possible, trim the edges of your blank so it’s a rough approximation of the final shape, or at least not wildly asymmetrical. This helps reduce vibration during the initial mounting and turning. You can do this with a bandsaw.
Consider Grain Direction: Think about how the grain will run relative to the faceplate. For bowls, you’ll typically want the bottom of the bowl centered on the faceplate.
Drilling Pilot Holes
This is a vital step for secure and safe mounting. Drilling pilot holes ensures your screws bite firmly into the wood and reduces the risk of splitting the blank.
Location: Use the screw holes on your chosen faceplate as a template. Transfer the positions of these holes onto your wood blank. Ensure you are drilling into solid wood, not towards the edges of a thin blank. Aim for at least 1.5 inches from the center of the blank to the screw hole locations on the faceplate.
Drill Bit Size: Select a drill bit that is slightly smaller than the diameter of the screw’s shank (the solid part without threads). For #8 screws, a 3/32″ or 7/64″ bit is often suitable. For #10 screws, a 9/64″ or 5/32″ bit might be appropriate. A test screw and drill bit on a scrap piece of the same wood is a good practice.
Depth: Drill the pilot holes deep enough for the screws to engage securely, but be mindful not to drill all the way through your blank unless that is intended for a specific design.
For example, if you’re turning a large platter, you might trace the faceplate onto the back of a roughly cut blank, then drill your pilot holes through these marked spots into the wood. This ensures your screws will go in straight and find maximum grip.
Mounting Your Wood Blank to the Faceplate
This is where the magic starts to happen. A properly mounted blank means safe and steady turning.
Step-by-Step Mounting Process
1. Attach Faceplate to Spindle: Ensure your lathe is off. Thread the faceplate onto your lathe’s spindle until it is snug. You don’t typically need to overtighten it aggressively; it should be secure.
2. Align Blank and Faceplate: Position your prepared wood blank against the faceplate, aligning the pilot holes drilled in the blank with the screw holes in the faceplate.
3. Insert First Screw: Start one screw into a pilot hole. Screw it in partially, just enough to hold the blank in place. Don’t fully tighten it yet.
4. Insert Second Screw (Opposite): Insert a second screw into a pilot hole directly opposite the first one. Again, screw it in partially. This helps to seat the wood and faceplate more evenly.
5. Insert Remaining Screws: Insert the rest of the screws into their respective pilot holes, screwing them in partially.
6. Tighten Screws Evenly: Now, systematically tighten all the screws. Work in a star or cross pattern (like tightening lug nuts on a car wheel). Tighten one screw a bit, then tighten the one opposite, then move to the next pair. This ensures even pressure and prevents the wood from developing stress.
7. Final Tightening: Once all screws are snug, go around one last time and tighten them firmly. They should be tight enough that the wood doesn’t move against the faceplate, but be careful not to strip the pilot holes. The wood should be held flat and securely against the faceplate.
Safety Checks Before Turning
Before you even think about powering up the lathe, perform these crucial safety checks:
Wobble Test: With the lathe off, gently try to wiggle the wood blank. It should feel completely solid and have no play.
Screw Security: Double-check that all screws are tight.
Tool Rest Clearance: Ensure your tool rest is positioned correctly and that there’s adequate clearance for the tool. You don’t want the spinning wood to strike the tool rest.
Unbalanced Load: If your blank is very irregular, it might be noticeably unbalanced. Start the lathe at the lowest speed setting possible to check for excessive vibration.
Eye Protection: Always wear safety glasses or a full face shield. Woodchips can fly unexpectedly.
Dust Mask/Respirator: For any turning, especially with MDF or certain hardwoods, wear respiratory protection.
A great resource for understanding safe lathe practices is the Occupational Safety and Health Administration (OSHA) website, which provides guidelines for workshop safety. For woodturning specifics, the American Association of Woodturners (AAW) also offers excellent safety resources.
Faceplate Turning Techniques for Success
Once your blank is securely mounted, it’s time to turn. The techniques for faceplate turning are similar to other lathe operations, but with a few considerations made easier by the stable mounting.
Roughing and Rounding
The first step is often to round over the blank and establish a basic shape.
Start Slow: Begin turning at the lowest lathe speed. As the blank starts to become more round, you can gradually increase the speed to a comfortable and safe level. A good rule of thumb is that the faster the tool speed, the smoother the cut, but always prioritize safety and stability.
Use a Roughing Gouge: A roughing gouge is ideal for removing large amounts of waste material and quickly bringing a square blank to a cylindrical shape.
Work from Edge to Center: When roughing, it’s often best to start cuts from the outer edge and work towards the center, or make slicing cuts across the face. Avoid jamming the tool straight into the spinning wood.
Check for Balance: As you round the blank, you’ll feel the balance improve. If you still experience significant vibration at higher speeds, stop the lathe and re-check your mounting or trim the blank further.
Shaping the Bowl or Platter
Once round, you can begin shaping the piece.
Bowl Gouce: A bowl gouge is excellent for hollowing and shaping the exterior curves of bowls and platters.
Scrapers: For achieving a very smooth finish on flat surfaces or final profiles, scrapers can be very effective. Be sure to use them correctly, with a very shallow bevel and a lead angle.
Hollowing: When hollowing, work in shallow passes. For faceplate-turned bowls, you’ll typically hollow the first side, then flip the piece to turn the outside and create the tenon or recess for mounting on the chuck for the second side.
Tailstock Support (If Possible): For very large or deep bowls, you may be able to use the tailstock for initial support during roughing or hollowing, especially if you’re working with an off-center blank. However, once hollowing begins, tailstock support might not be feasible.
Finishing and Removing from the Faceplate
The final stages involve refining the shape and parting the piece from the faceplate.
Sanding: Sand your piece to your desired smoothness. It’s often easiest to sand while the piece is still mounted on the faceplate, starting at lower speeds and gradually increasing.
Parting Off: To remove the piece from the faceplate, you’ll typically turn a tenon or recess on the back that can be held by your lathe chuck. You can then carefully cut away the remaining wood attached to the faceplate.
Creating a Tenon: Mount your chuck and set it up to grip a tenon that you will turn into the back of your piece. Carefully use a parting tool or bowl gouge to create this tenon.
Cutting Away Waste: Once the tenon is ready, mount the piece in the chuck. Then, with the lathe off, advance the tool rest so it’s in position to carefully remove the wood holding it to the faceplate. You can then turn the bulk of the waste away.
Controlled Removal: Always ensure the faceplate itself is securely held while you remove the wood attached to it. Sometimes, using a thin parting tool to create a kerf, followed by a scraper or gouge, is the safest approach.
Don’t Forget the Faceplate Screws: Be patient when removing screws from the wood. If they’re stubborn, a little penetrating oil or careful tapping might help. Remove all screws before attempting to detach the wood entirely.
Dealing with Common Faceplate Turning Issues
Even with the best preparation, you might encounter a snag. Here are some common problems and how to solve them.
Vibration and Wobble
This is the most common issue, and usually the most dangerous.
Cause: Unbalanced wood blank, loose mounting, or damaged faceplate.
Solution:
Ensure all screws are fully tightened.
If the blank is very irregular, trim it further on a bandsaw to create a more symmetrical rough shape.
Check that the faceplate is securely threaded onto the spindle.
If vibration persists even after securing everything, the wood itself might be too unbalanced, or there might be internal stresses. Consider reducing the turning speed significantly or stopping the project if it’s unsafe.
Splitting or Cracking Wood
Wood can split due to excessive force, dry conditions, or inherent flaws.
Cause: Overtightening screws, drilling pilot holes too small, or turning too aggressively.
Solution:
Always use pilot holes that are appropriately sized for your screws.
Tighten screws firmly but do not overtighten.
When removing wood, take shallow cuts, especially on larger diameters.
If you notice a small crack starting, you might be able to arrest it with a bit of wood glue and a clamp, or by reinforcing the area with thicker screws if it’s on the back. For critical areas, a thicker faceplate may be warranted.
Stripped Pilot Holes
This happens when the screw can no longer grip the wood securely.
Cause: Pilot hole drilled too large, screw driven with too much force, or wood that is too soft.
Solution:
For a quick fix on a less critical area, you can try a slightly larger diameter screw.
A more robust solution is to use a wood repair product like a dowel or wood filler mixed with sawdust to fill the hole, let it dry, and then re-drill a pilot hole.
For critical structural integrity, you may need to move the mounting screw location or even re-blank the piece.
Faceplate Not Tightening on Spindle
Sometimes the faceplate feels loose even when threaded on.
Cause: Worn spindle threads, worn faceplate threads, or foreign material.
Solution:
Clean both the spindle threads and the faceplate threads thoroughly with a wire brush.
Inspect for visible damage to the threads. Minor damage might be repairable with thread files, but significant damage may require replacing the faceplate or even the spindle nose if it extends beyond standard repairs.
* Ensure you have the correct thread size.
