Make a Juice Groove on a Cutting Board: No Jig Required

I have recently been making quite a few cutting boards, and I have cut a juice groove into all of them. So, I wanted to share with you my method of routing out a juice groove.

This method doesn’t require a CNC, or a complex jig that fits on your cutting board. Instead, all it uses is a palm router and an edge guide. That’s one of the main things I love about this method of making a cutting board juice groove – the simplicity!

CNC machines are amazing when you have one, but they definitely aren’t a staple in many shops (mine included). I also didn’t want to build a complex jig that has to be adjusted for every new board I make. So, after testing out this method on many, many cutting boards, I can safely say that this is my favorite method.

So, whether you call it a juice groove, a blood groove, or a drip edge; keep reading to find out a simple method of how to route one!

Safety

First, let’s talk about safety. Like I mentioned, this method uses a palm router. Just by the nature of this, there are inherent risks in using a power tool like a palm router. Use yours only if you feel safe and confident in using it.

Wear all of the proper safety equipment (these are my favorites ways to protect eyes, ears, and lungs). Read your owner’s manual and fully acquaint yourself with the power tool before you use it.

Step 1: Gather your Materials

• palm router
• edge guide that fits your router
• 3/8″ round nose bit
• clamps
• combination square
• cutting board (here is a great tutorial for how to make a cutting board)

Step 2: Attach Router Bit and Edge Guide

This step is assuming you have already made your cutting board. For a tutorial for how to joint long boards without a jointer, check out this post. Straight edges are imperative when making your own cutting board!

Q: What is the best router bit for a juice groove?

The correct router bit to use in order to cut a juice groove is a 3/8″ round nose bit.

This is the edge guide I have. It attaches to the side of your router and provides a fence for the router to push against.

Step 3: Set the Depth

Q: How far from the edge should a juice groove be?

A: A good distance for a juice groove to be is 3/4″. This is the distance from the edge of the board to the closest edge of the juice groove.

I set my combination square to 3/4″. This will be the distance from the edge of the board to the edge of the juice groove.

Put your combination square on the router bit, flush with the edge guide. Tighten the edge guide to where the edge of the bit equals the 3/4″ measurement on the combination square.

Step 4: Mark your Board

Using your combination square set to 3/4″, mark that distance on every corner of the board. Make your marks prominent, because this is what you will be looking for while you are routing. You will stop at these marks.

Step 5: Route the Juice Groove

Clamp the cutting board to your workbench. Be sure to leave room for the router to move freely.

Start by plunging the router with the edge guide flush against the edge. Tilt it to the side, wait for the bit to reach full speed, and slowly lower the router bit into the piece.

Inch your way to the right, until you meet the mark that you previously made. Then, slowly and steadily, work your way left until you reach the other mark on the left side.

A couple tips when you are routing the blood groove – if you are getting burn marks in your groove, you are probably going too slow. If the wood is chipping, you are probably going too fast, or you need a new router bit.

Also, make multiple shallow passes. Start shallow and gradually go deeper. While this does take longer, it is safer and you will get a better result in the end.

Figuring out which way to run your router can be a little confusing. I found this article on how to use the correct router feed direction very helpful.

Turn off the router and allow it to fully stop before you lift it off the cutting board.

Repeat this on the other 3 sides.

I also did this same method to make a cigar rest when I made this wooden cigar ashtray.

Another great way to upgrade your board is to add a handle. Find a tutorial for how to route a finger groove handle on your cutting board here! I also love to add an inlay to my cutting boards. My favorite is a Texas inlay from Slab Stitcher – here is a tutorial for how to create perfect wooden inlays!

You can now sand and seal your board. My favorite method of sanding to create to smoothest finish is this:

• sand with 80 grit sandpaper
• spray with water to “water pop” the board
• allow it to dry
• sand again with 120 grit sandpaper

Seal it with Odie’s Oil. It is food safe, creates great protection for the cutting board, and smells amazing!

And that’s it! I love this simple way to cut a drip edge on a cutting board. It’s even better that no CNC is required. And not only that, but you don’t have to make a complex router groove jig that fits the board. All you need is an edge guide for your router!
