black locust wood

The Complete Guide to Black Locust Wood

If you’re looking for durable and long-lasting wood that will add a touch of color to your project, black locust (false acacia) is a great choice. The wood is abundant, eco-friendly, and relatively affordable, making it a popular option for many construction projects. So if you’re looking for something different for your next project, give black locust wood a try. You won’t be disappointed.

Where is Black Locust Wood Grown?

While black locust wood can be found all over the world, it’s most often sourced from China. The climate there is perfect for producing strong and durable wood.

Black locust wood is also grown in the United States, but it’s not as common as the Chinese variety. This is largely due to the fact that many people are wary of planting trees in regions where they might spread quickly.

This fear isn’t without merit, as black locust can be an invasive species. But with proper care, it can be grown and managed without causing too much damage to the environment.

Common Black Locust Wood Uses

There are many reasons to love and use black locust wood. For one, it’s incredibly strong and durable. In fact, it’s often used as a construction material for buildings.

It’s also resistant to rot, insects, and decay. This makes it ideal as an outdoor building material since it won’t rot in the rain or succumb to insects.

Black locust wood is also a great choice for furniture. It has a beautiful, golden color that darkens over time. And because it’s incredibly tough, it can be sanded and refinished multiple times without losing its luster.

Black Locust Wood for Buildings

Black locust wood is an incredibly versatile building material that’s impervious to decay, insects, and rot. One of the most important uses for black locust wood? It can last up to 100 years without rotting.

And that’s not the only reason black locust wood is so popular in construction. It also repels termites, which makes it a great choice for outdoor structures. The tough fibers of this type of wood are almost impossible to break or tear by hand.

Also, Black locust posts are so strong, it’s often used in buildings. For example, fences and posts are a popular use. And for decking, black locust is also a great option. People choose the black locust deck because of its longevity and slip resistivity.

It can be especially useful for houses that have already been built since you won’t need to replace the fence every few years as you might with other materials. This saves homeowners both time and money.

And if they move away or sell their house, they don’t have to worry about removing the fence before listing their home on the market, either.

Another common use of black locust wood is siding walls. Since this type of material doesn’t rot easily, it lasts much longer than traditional wooden boards do when exposed to rain or sunlight over an extended period of time.

black locust furniture treeBlack Locust Wood Furniture

Black locust wood is often used in the construction of fine furniture. The wood’s natural color and beauty make it a popular choice for high-end pieces.

In addition, black locust is one of the hardest woods and stiffest domestic timber available. This makes it perfect for furniture that will be used outdoors or in areas where there’s a lot of traffic.

Due to its strength and durability, black locust wood furniture can last for generations with proper care. It’s also easy to clean and maintain, making it a good option for busy families.

You can use thin slats of black locust wood to create furniture pieces like tables and chairs. This type of design is known as the “slat” or “shaker” style because it was popularized by the Shakers, a religious group that believed in simple living.

Black locust wood is also often used to make guitars and other stringed instruments. The wood is strong and resonant, making it the perfect material for these delicate instruments.

Fuel

As a strong, durable wood, Black Locust is an extremely good source of fuel for homeowners. Because Black Locus is rot-resistant and grows abundantly, it’s an excellent tree for firewood.

Black Locust Wood Appearance

As we mentioned before, black locust wood has a beautiful golden color. Over time, this color will deepen to a rich brown or black.

It’s also important to note that black locust wood is as strong as it is beautiful. The grain of the wood has a unique swirl that’s beautiful to look at.

black locustThe beautiful wood grain of black locust is what often attracts people to use it in furniture and cabinetry. The color can range from a light honey brown to a darker chocolate brown, and the texture is usually quite smooth.

Black locust lumber is also free of knots, which means there are fewer blemishes in the wood. This results in a higher-quality finished product.

When it comes to black locust trees, sometimes people confuse the black locust tree with the honey locust tree. However, both are different types of trees and wood. Black locust trees have coarse bark that appears to be curly with a pattern of furrows interwoven like ropes. In contrast, honey locust trees, with gray bark, and their branches are covered with red-brown thorns.

Black Locust Wood Strength

Black locust wood is often chosen for projects that require a high degree of strength and toughness. This type of wood is very resistant to decay and termites, but it is also relatively easy to work with. It has a beautiful grain and is often used in furniture and cabinetry.

black locust grainThe Janka hardness of the black locust is 1700 lbf (7600 N). The wood is heavy and strong, with a density of approximately 44 lb/ft3 (700 kg/m3). It is used for applications such as boatbuilding, fence posts, and foundation piles. 

Black Locust Wood Durability

Another reason black locust wood is often used in construction projects is that it is highly durable. It can withstand the outdoor elements very well and has a high resistance to moisture, fire damage, and insect infestations.

Black Locust Wood Sustainability

The sustainability of black locust wood is a hot topic among forestry professionals. This is due in part to the black locust tree’s rapid growth rate, as well as its resistance to pests and diseases. Black locust also has a long lifespan, making it an attractive option for sustainable forestry initiatives.

Sustainable forestry is the management of forests in a way that ensures their long-term viability. This can be done through practices like selective logging, which allows trees to mature and regenerate. Sustainable forestry also takes into account the needs of local communities and the environment.

Black locust is an excellent choice for sustainable forestry initiatives. It grows quickly and can be harvested without damaging the tree’s deep root system. 

Further, the shade provided by black locust trees helps to slow soil erosion and preserve soil moisture. This means that black locusts can grow in infertile soils, helping to maintain biodiversity in an area. Black locust also provides habitat for wildlife while protecting the topsoil from erosion.

Black locust is resistant to most pests and diseases. It also tolerates drought very well, meaning little irrigation is needed after it has been planted. This reduces the cost of management for foresters.

Black locusts’ wood is extremely dense, making it an excellent choice for many applications. The wood does not warp easily and stands up well to weathering. It is also easy to work with, making it a popular choice for flooring, furniture, and other construction projects.

FSC Certified 

The best part is that black locust is a sustainable, FSC certified material. You can trust that the wood you’re buying comes from an environmentally friendly source with this certification.

Is There Any Downside of Black Locust Wood?

One downside to black locust wood is that it can be difficult to work with. The wood is prone to splitting, so care must be taken when cutting or shaping it. However, the benefits of this sturdy hardwood outweigh the few drawbacks compared to any other wood species. 

Conclusion

Black locust wood is an excellent choice for many construction projects because it is strong, durable, and sustainable. It has a beautiful grain that will add elegance to any project. Plus, this type of lumber does not require replanting after harvesting, making it a more sustainable choice.

The Features Tour will give you a quick run-down on all the features the MX can do for you. The Tutorials are easy to follow even for the first time CNC machinist.
Feel free to download the MX on any of your computers. We recommend downloading the MX along with your CAD and CAM software there at the comfort of your office computer to generate your tool path programs. You don’t need to be hooked up to the machine either to test your program in simulation mode.

Slide 1

4. Navigate and Edit Your Program through the MX interface with Ease
With a few clicks of the mouse or using touch screen technology, you can easily navigate through the MX interface importing saved programs into the Editor from the File drop down menu. Using standard windows features to edit your program you can then lock the Editor Screen to avoid accidental editing, and if you need to insert a line in the middle of a program, just click on [ReNum] to re-number your tool path list.
You can create a program or import CAM generated G-code tool paths into the Editor
The X Y and Z W arrow jog buttons are displayed from the point of view of the cutter to avoid confusion when the table and saddle are moving. You can also adjust your spindle speed and coolant control while jogging each axis.

Slide 1

5. Feed Hold – Pause in the Middle of your Program
Feed Hold lets you pause in the middle of a program. From there you can step through your program one line at time while opting to shut the spindle off and then resume your program.
You can also write PAUSE in the middle of your program and jog each axis independently while your program is in pause mode.

Slide 1

6. Hot Keys
Hot Keys is an alternative method to easily control your machine using your hard or touch screen keyboard. One can press P to pause a program, press S to turn Spindle On, G to run a program, Space Bar to Stop, J to record your individual movements one line at a time to create a program in teach mode.

Slide 1

7. Pick Menu – for conversational mode programming
Write FANUC style G-codes directly into the Editor or select commands off the [Pick] menu and write your tool path program in conversational mode such as what is written in the Editor box. You can even mix between conversation commands and G-codes in the same program.

Slide 1

8. Pick Menu List of Options
Use commands such as MOVE, SPINDLE ON/OFF, COOLANT ON/OFF, PAUSE, DELAY, GO HOME…. to write your tool path programs in conversational mode.

Slide 1

9. Draw the Tool Path to verify it before pressing Go
Hit Draw to view your tool path program drawing, check out its run time, or even simulate the tool path in 3D mode. This can be helpful to quickly verify your program before running it. You can also slow down or speed up the drawing or simulation process.
You can also hit Go within the Draw Window itself to verify the cutter’s position on the machine. The current tool path will be highlighted and simultaneously draw out the next path so you can verify what the cutter will be doing next on the program.

Slide 1

10. Run each tool path independently to study its movement
1. Run the machine on Trace mode. You can run each tool path independently, one line at a time to study the tool path movement on the machine to verify the position of the application and if any fixture/vise is in the way of the cutter’s path.

2. You can also verify your program by clicking on the Trace and Draw buttons together. This will allow you to view each tool path independently one line at a time in the Draw Window.

Slide 1

11. Counters display in Inches or Millimeters – Continuous Feed
1. When running a program, the counters will display a “real-time” readout while the machine is in CNC operation without counting ahead of the movement.
2. The current tool path is highlighted while the machine is in operation without causing slight interruptions/pauses as the software feeds the tool path to the machine. The MX internally interprets a program ten lines ahead to allow for “continuous machining” avoiding slight interruptions as the machine waits for its next tool path command.
3. “Run Time” tells you how long it takes to run your tool path program.

Slide 1

12. Use the “Go From Line” command to start in the middle of your program
If you ever need to begin your program from somewhere in the middle of it, use [Go From Line] which you can find under Tools. The Help guide will walk you through how to position the cutter without losing its position on the machine.

Slide 1

13. Exact Motion Distance without over-stepping on an axis while jogging
Use “Relative ON” to enter a specific coordinate to jog any of your axes to an exact location without having to write a program. It’s like using “power feed” but easier. You can jog an exact distance on any of the axes without needing to keep the key pressed down and mistakenly over-step the movement releasing your finger too slowly off the jog button.
Let’s say you need to drill a hole exactly 0.525” using the Z. So you enter 0.525 in the Z box. Next, adjust the JOG FEED RATE slider for the desired feed rate. Then “click once” on the +Z or -Z button to activate the travel. In this case you click once the -Z button first to drill the hole exactly 0.525”. Then click once on the +Z button to drive the axis back up 0.525”.

Slide 1

14. Teach Mode – Jog Input
You can create a tool path program by storing each point-to-point movement by simply jogging an axis one at a time. Click on either of the Jog Input buttons to store each movement on the Editor Screen. You can then add Spindle ON, feed commands, and press GO to run the new program as needed. This is a great feature to help you learn to create a program by the movements you make on the machine without necessarily writing out an entire program first.

Slide 1

15. Override on the fly to adjust the Jog Feed to Rapid or the Spindle Speed during the middle of a program
1. Jog Feed and Rapid with Override: You can adjust feeds using the slider from slow minimum 0.1″ per minute to a rapid of 100″ per minute of travel. You can even micro-step your jog as low as 0.01”/min. The [-][+] buttons allow you to fine tune feeds in 5% increments while the program is in motion.
2. Spindle Speed with Override: You can adjust speeds using the slider from a slow minimum RPM to the max RPM according to the machine setup. The [-][+] buttons allow you to fine tune feeds in 5% increments while the program is in motion.

Slide 1

16. Adjust Counters using Pre-Set if you cannot begin the program from 0.00
In a situation where you cannot begin your cutter at it’s 0.00 location, you can “Pre-Set” directly into the counters by typing in your beginning coordinate. You can press Go from here to run your program. You can also “zero all” or “zero” your counters independently. With one click of the [Return to 0.0] button, all axes will travel back to its respective 0.0 on the machine.

Slide 1

17. Set and Save your 0.00 position for future runs
Set and save your 0.00 position on the machine. These coordinates will be recorded as the first line of the program in the Editor Screen. Should you desire to return to this program at a later date, you only have to click on the Set Zero Return button. This will command the machine to automatically jog each axis to its saved “set” 0.00 position according to the recorded coordinates at the first line of the program.

Slide 1

18. Create a “Home” position to clear your application and run multiple times
Let’s say you need to machine one application times 100 pieces. This usually requires a jig to retain that physical 0.00 position. But in this case, you want the program to end with a clearance of the axes to easily switch out the next piece of stock and start again. With Save Home, you have the ability to save this offset (home) position while still retaining your Set Zero position where the machine will mill your part out. Pressing [Save Home] will record this new position under the Set Zero line in your program.
Pressing [Go Home] will jog your axes back to your “saved home” position where you originally pressed the Save Home command. You can also input GO_HOME from the Pick Menu as its own tool path in your program. At the completion of your program the axes will end at your Home position. Replace your part, then press [Return to 0.0] button to allow the axes to return to its zero position, and press Go to start your next run.

Slide 1

19. Disable the axis motors to manually hand crank each axis into place
Easily de-energize the axis motors by clicking [Disable Motors] to crank each axis by hand, and then press [Reset Control] to re-energize the axis motors.

The CNC Masters Automatic Tool Changer Rack and Tools (US Patent 9,827,640B2) can be added to any CNC Masters Milling Machine built with the rigid tapping encoder option. The tutorial will guide you through the set-up procedure using the ATC tools.

Slide 1

22. Use the optional Rigid Tapping Wizard without the need for tapping head attachments
When you order your CNC Masters machine, have it built with the optional rigid tapping encoder. You can take any drill cycle program and replace the top line with a tapping code created by the wizard to tap your series of holes up to 1/2” in diameter.

Slide 1

23. Use the optional Digital Probe to scan the profile and/or pockets of your fun/hobby type designs to write your tool path program and machine out a duplicate of your original design To “surface” scan an object, you can program the probe along the X or Y plane. The stylus will travel over the part starting on the left side front corner of the object and work its way to the end of the part on the right side. Depending on how the stylus moves, it will record linear and interpolated movements along the X, Y, and Z planes directly on the MX Editor.
To “pocket” scan an object containing a closed pocket such as circles or squares, the scan will start from the top front, work its way inside of the pocket, and scan the entire perimeter of the pocket.
Under the Setup of the MX software you will find the Probe Tab which will allow you to calibrate and program your probe. Your “Probe Step”, “Feed”, and “Data Filter” can also be changed on the fly while the probe is in the middle of scanning your object.

Slide 1

24. Use work offsets G54-G59 for nesting applications
The work offsets offer you a way to program up to six different machining locations. It’s like having multiple 0.0 locations for different parts. This is very useful especially when using sub-routines/nesting applications.

Slide 1

25. Create a Rectangular Pocket / Slot with our selection of Wizards to help you build a tool path program
The Cycle Wizards for the mill or lathe makes it easy to create a simple tool path without needing to use a CAD and CAM software.
On this Wizard, the Rectangular Pocket / Slots, can be used to form a deep rectangular pocket into your material or machine a slot duplicating as many passes needed to its total depth.

Slide 1

29. Create a Peck Drilling Program in Circular or Rectangular Patterns
Using the Circular or Rectangular Drilling Wizards, you can program the machine to drill an un-limited series of holes along the X and Y planes. Program it to drill straight through to your total depth, use a high-speed pecking cycle, or deep hole pecking cycle. You can program the cut-in depth and return point for a controlled peck drill application to maximize chip clearance.

Slide 1

30. The MX interface can easily be interchanged from Mill Mode to Lathe Mode
Use this interface for your CNC Masters Lathe. It contains all the same user-friendly features and functions that comes in Mill Mode. Simply go to the Setup page and change the interface.

Slide 1

31. Use Tool Change Compensation or the optional Auto Tool Changer Turret if your application requires more than one tool in a single program
You can offset the length and angle of each tool and record it under Tools in your Setup. The program will automatically pause the lathe’s movement and spindle allowing you to change out your tool, or allowing the optional ATC Turret to quickly turn to its next tool and continue machining.
On the MX interface, you also have four Tool Position buttons. Select your desired T position, and the auto tool post will quickly turn and lock itself to that position.

Slide 1

32. Use the Lathe Wizard Threading Cycle to help you program your lathe’s internal or external threads in inches or metric

Slide 1

33. Use the Lathe Wizard Turning / Boring Cycle to help you program simple turning and boring cycles without having to go through a CAM or writing a long program with multiple passes
