Chainsaw Trenching Gear (Affordable DIY Tips for Woodworkers)

It seems contradictory, doesn’t it? Wanting to be both a careful craftsman and a budget-conscious woodworker? It’s a dance I know well, and one that’s entirely possible, especially when tackling chainsaw trenching. My years in the woods have taught me that ingenuity can often trump expensive equipment. So, let’s dive into the world of affordable DIY chainsaw trenching gear for woodworkers.

Chainsaw Trenching: A Woodworker’s Secret Weapon

Chainsaw trenching, at its core, is the art of using a chainsaw to create controlled, narrow excavations in wood. I have personally used it for everything from intricate joinery to creating decorative effects on larger timber pieces. It’s a technique that opens up a world of possibilities, and with a few clever DIY adaptations, it can be incredibly accessible.

Why Chainsaw Trenching?

Think of it as a power chisel on steroids. Here’s why I find it invaluable:

• Precision: Allows for controlled material removal, vital for joinery.
• Speed: Faster than hand tools for larger trenches.
• Versatility: Adaptable to various wood types and projects.
• Cost-Effective: With DIY methods, it’s budget-friendly.

Understanding the Basics

Before diving into DIY modifications, let’s understand the fundamentals.

Chainsaw Safety

Safety is paramount. I cannot stress this enough.

• Personal Protective Equipment (PPE): Always wear safety glasses, hearing protection, gloves, and chainsaw chaps. I’ve seen too many accidents that could have been avoided with proper PPE.
• Chainsaw Maintenance: Ensure your chainsaw is in good working order. A sharp chain is a safe chain. Regular maintenance is key.
• Kickback: Be aware of the danger of kickback. Use proper techniques and maintain a firm grip. Never cut with the tip of the bar.

Chainsaw Types

The type of chainsaw you use will influence your trenching capabilities.

• Small Chainsaws (14-16 inch bar): Ideal for detail work and smaller trenches. Easier to control.
• Medium Chainsaws (18-20 inch bar): A good all-around option for various trench sizes.
• Large Chainsaws (20+ inch bar): Suitable for large-scale trenching, but require more skill and strength.

For most DIY woodworkers, a small to medium-sized chainsaw will be sufficient. I personally prefer a 16-inch bar for most of my trenching work.

Chainsaw Chains

The type of chain also matters.

• Full-Chisel Chains: Cut faster but are more prone to kickback.
• Semi-Chisel Chains: More forgiving and easier to control, making them ideal for beginners.
• Low-Kickback Chains: Designed to reduce the risk of kickback.

I recommend starting with a semi-chisel or low-kickback chain, especially if you’re new to chainsaw trenching.

Affordable DIY Trenching Gear: My Top Tips

Now, let’s get into the heart of the matter: creating affordable trenching gear. I’ve spent years refining these techniques, and I’m confident they’ll work for you.

1. The Depth Gauge Modification

This is the most fundamental modification. It involves adjusting the depth gauges on your chainsaw chain to control the depth of cut.

• What are Depth Gauges? These are the small metal protrusions in front of each cutting tooth on the chain. They limit how deeply the tooth can bite into the wood.
• Why Modify Them? By filing down the depth gauges, you can increase the depth of cut, making trenching more efficient.

How to Do It:

1. Safety First: Remove the chain from the chainsaw and secure it in a vise.
2. Marking: Use a depth gauge tool (or a small file) to mark the desired depth of cut. I usually recommend starting with a depth of 0.025 inches for softwoods and 0.020 inches for hardwoods.
3. Filing: Carefully file down the depth gauges to the marked depth. Use a flat file and maintain a consistent angle.
4. Rounding: Round off the front of the depth gauges to prevent them from digging into the wood too aggressively.
5. Reinstall: Reinstall the chain on the chainsaw.
6. Test: Test the chain on a scrap piece of wood. Adjust the depth gauges as needed.

My Experience: I remember the first time I modified my depth gauges. I was working on a large timber frame project and needed to create deep mortises. The standard chain was taking forever. After carefully filing the depth gauges, the chainsaw cut through the wood like butter. It saved me hours of work.

Important Note: Modifying depth gauges increases the risk of kickback. Use extreme caution and maintain a firm grip on the chainsaw.

2. The Homemade Milling Attachment

For wider trenches or more controlled cuts, a milling attachment is invaluable. Commercial milling attachments can be expensive, but you can easily build one yourself.

• What is a Milling Attachment? A milling attachment guides the chainsaw along a straight line, allowing you to make precise, consistent cuts.
• Why Build One? It provides greater control and accuracy than freehand trenching.

How to Build It:

1. Materials: You’ll need two pieces of angle iron (approximately 4 feet long), a piece of plywood (approximately 2 feet by 4 feet), bolts, nuts, and washers.
2. Assembly:
   • Attach the angle iron to the plywood, creating a frame. The distance between the angle iron should be slightly wider than the width of your chainsaw bar.
   • Drill holes in the angle iron to accommodate bolts.
   • Attach the chainsaw to the angle iron using bolts, nuts, and washers. Ensure the chainsaw is securely mounted.
3. Guide Rail: Attach a straight piece of lumber to the workpiece to act as a guide rail.
4. Operation: Place the milling attachment on the guide rail and push the chainsaw along the rail to make the cut.

Detailed Measurements and Specifications:

• Angle Iron: 2 pieces, 4 feet long, 1.5 inches x 1.5 inches.
• Plywood: 2 feet x 4 feet, 3/4 inch thick.
• Bolts: 1/4 inch diameter, various lengths.
• Guide Rail: Straight piece of lumber, at least 8 feet long.

Case Study: I once used a homemade milling attachment to create a series of precise trenches in a large cedar log. I was building a custom planter box and needed to create channels for drainage. The milling attachment allowed me to make perfectly straight and consistent trenches, resulting in a beautiful and functional planter box.

Tips:

• Use a level to ensure the guide rail is perfectly straight.
• Apply a small amount of oil to the guide rail to reduce friction.
• Take multiple passes for deeper trenches.

3. The Chainsaw Protractor

For angled trenches, a simple protractor can be a lifesaver.

• What is a Chainsaw Protractor? A device that allows you to set the chainsaw at a specific angle for angled cuts.
• Why Use One? It ensures accuracy and consistency when creating angled trenches.

How to Build It:

1. Materials: You’ll need a piece of plywood (approximately 1 foot by 1 foot), a protractor, a hinge, bolts, nuts, and washers.
2. Assembly:
   • Attach the protractor to the plywood.
   • Attach the hinge to the plywood, adjacent to the protractor.
   • Attach the other side of the hinge to a small piece of wood that will rest against the chainsaw bar.
   • Adjust the angle of the protractor to the desired angle.
   • Secure the chainsaw bar against the small piece of wood and make the cut.

Measurements:

• Plywood: 1 foot x 1 foot, 1/2 inch thick.
• Protractor: Standard protractor.
• Hinge: Small hinge.

Real-World Example: I used a chainsaw protractor to create angled trenches for a custom headboard. The headboard had a series of angled slats, and the protractor allowed me to create perfectly angled trenches for the slats to fit into.

4. The Chainsaw Stabilizer

For added stability, especially when working on uneven surfaces, a chainsaw stabilizer is a must.

• What is a Chainsaw Stabilizer? A device that supports the chainsaw and prevents it from wobbling or tilting during operation.
• Why Use One? It improves safety and accuracy, especially when working on large or awkward pieces of wood.

How to Build It:

1. Materials: You’ll need a piece of plywood (approximately 2 feet by 2 feet), two pieces of lumber (approximately 2 feet long), bolts, nuts, and washers.
2. Assembly:
   • Attach the two pieces of lumber to the plywood, creating a frame.
   • Cut a hole in the plywood to accommodate the chainsaw bar.
   • Place the chainsaw on the stabilizer and secure it with straps or clamps.

Specifications:

• Plywood: 2 feet x 2 feet, 3/4 inch thick.
• Lumber: 2 pieces, 2 feet long, 2 inches x 4 inches.

Personal Story: I once used a chainsaw stabilizer while working on a fallen tree in the woods. The tree was lying on a steep slope, and it was difficult to keep the chainsaw stable. The stabilizer provided a solid base of support, allowing me to make safe and accurate cuts.

5. The Chainsaw Sharpening Jig

A sharp chain is essential for efficient and safe chainsaw trenching. A sharpening jig makes it easier to maintain a sharp chain.
