Tip #1: Designing and Building Your Chainsaw Jig

The heart of any successful cutting board project is a well-designed jig. I’ve experimented with countless designs over the years, and I’ve found that simplicity and adjustability are key.

Essential Components

Base: A sturdy platform that supports the wood. I recommend using ¾-inch plywood for its stability and affordability.
Rails: Parallel tracks that guide the chainsaw. These can be made from steel angle iron, aluminum extrusions, or even hardwood.
Carriage: A sliding platform that holds the chainsaw and moves along the rails. This is where precision is paramount.
Clamps: Securely hold the wood in place to prevent movement during cutting. Toggle clamps or quick-release clamps work well.

My Go-To Jig Design

I prefer a simple, adjustable jig that can accommodate different sizes of wood. Here’s a breakdown of my design:

Base: A 24″ x 48″ piece of ¾-inch plywood.
Rails: Two 48″ lengths of 1 ½” x 1 ½” steel angle iron, mounted parallel to each other on the base. The distance between the rails should be slightly wider than the width of your chainsaw bar.
Carriage: A rectangular frame made from 2″ x 4″ lumber, with steel plates attached to the bottom that slide along the rails.
Chainsaw Mount: A simple bracket that securely holds the chainsaw to the carriage. I use a combination of bolts and clamps to ensure a tight fit.
Clamps: Four toggle clamps, mounted on the base, to hold the wood in place.

Building Your Jig: A Step-by-Step Guide

Cut the Plywood Base: Use a circular saw to cut the plywood to the desired size.
Attach the Rails: Position the steel angle iron rails on the base, ensuring they are parallel and evenly spaced. Secure them with screws or bolts.
Build the Carriage: Construct the rectangular frame from 2″ x 4″ lumber. Attach the steel plates to the bottom of the frame, ensuring they slide smoothly along the rails.
Mount the Chainsaw: Attach the chainsaw bracket to the carriage. Secure the chainsaw to the bracket with bolts and clamps.
Install the Clamps: Mount the toggle clamps on the base, positioning them to hold the wood securely.

Takeaway: A well-designed and constructed jig is essential for achieving accurate and consistent cuts. Spend time planning and building your jig carefully.

Tip #2: Choosing the Right Chainsaw and Bar

Not all chainsaws are created equal.

Chainsaw Size and Power

Engine Size: I recommend a chainsaw with an engine size of 50cc to 60cc for most cutting board projects. This provides enough power to cut through hardwoods like maple, walnut, and cherry.
Power Output: Look for a chainsaw with a power output of around 3 to 4 horsepower. This will ensure you have enough muscle to tackle thicker slabs of wood.
Weight: Consider the weight of the chainsaw, especially if you’ll be using it for extended periods. A lighter saw will be easier to maneuver and reduce fatigue.

Bar Length and Type

Bar Length: The length of your chainsaw bar should be slightly longer than the width of the cutting boards you plan to make. A 20-inch bar is a good all-around choice for most projects.
Bar Type: I prefer using a laminated bar for cutting boards. These bars are lighter and more maneuverable than solid bars.
Chain Type: A ripping chain is designed specifically for cutting wood along the grain. This type of chain will produce smoother, cleaner cuts than a standard crosscut chain.

Chainsaw Recommendations

Stihl MS 271 Farm Boss: A popular and reliable chainsaw that’s well-suited for cutting boards.
Husqvarna 455 Rancher: Another excellent choice, known for its power and durability.
Echo CS-590 Timber Wolf: A more affordable option that still delivers good performance.

Tip #3: Preparing Your Wood for Cutting

Properly preparing your wood is essential for achieving the best possible results. This involves selecting the right type of wood, drying it properly, and preparing the surface for cutting.

Wood Selection

Hardwoods: Hardwoods like maple, walnut, cherry, and oak are ideal for cutting boards. They are durable, resistant to wear and tear, and have attractive grain patterns.
Avoid Softwoods: Softwoods like pine and fir are not suitable for cutting boards. They are too soft and will dent and scratch easily.
Grain Orientation: Choose wood with a tight, straight grain. This will make it easier to cut and will result in a stronger, more durable cutting board.

Drying Your Wood

Kiln Drying: Kiln-dried wood is the best choice for cutting boards. It has a consistent moisture content and is less likely to warp or crack.
Air Drying: If you’re using air-dried wood, make sure it’s properly seasoned. This can take several months or even years, depending on the type of wood and the climate.
Moisture Content: The ideal moisture content for cutting board wood is between 6% and 8%. Use a moisture meter to check the moisture content before cutting.

Preparing the Surface

Planing: Use a planer to flatten and smooth the surface of the wood. This will ensure that the jig sits flat and that your cuts are accurate.
Jointing: Use a jointer to create a perfectly straight edge on the wood. This will provide a reference surface for your jig.
Sanding: Sand the surface of the wood to remove any imperfections. Start with a coarse grit sandpaper (80-grit) and gradually work your way up to a finer grit (220-grit).

Real-World Example: I once tried to cut a cutting board from a piece of wood that hadn’t been properly dried. The result was a warped, uneven mess. I learned my lesson the hard way!

Takeaway: Properly preparing your wood is essential for achieving the best possible results. Select the right type of wood, dry it properly, and prepare the surface for cutting.
