The 1-Second Trick to More Accurate Measuring and Marking for Your Woodworking Projects

If you want gap-free joinery and a perfect, long-lasting fit for both strength and aesthetics, precise measuring and marking of parts is essential. But, each step of the process — measuring, transferring marks, and cutting — can introduce tiny little errors of 1/64 or 1/32", which, over the course of a project, can add up significantly. So here's a simple little trick that takes no extra time, but creates much more accurate results.    

 The measuring process usually looks like this. You take a tape measure or long rule and determine the length and mark that spot with a pencil. Then, you grab a square and extend you mark across the width of the wood, at a perfect ninety degrees. Then you use a saw to cut it to length.

Most often, we'll place the square on the mark, and use the pencil or a marking knife to transfer the line across the face. But here's the rub: the pencil line itself takes up space, often 0.5 or 0.7mm, about 1/64". Compounded across the entire project, those numbers start to add up. 

So, instead, don't place the square on your line and run the pencil or marking knife along its edge. Place your pencil/marking knife first, then slide the square up to it to create a long line across the exact same point.

 

It's super simple. Measure your length, and grab both your square and pencil. Place the pencil on your tick mark.

 

Then, register your square on the edge, and slide to your pencil until it touches the graphite. Now, extend the mark across the face. 

 

You can see what a difference this makes in the photo above. Even with a super fine mechanical pencil, the difference is significant.

 

The best thing is: this takes absolutely no more time than doing it the square-first way. It's just a bit of muscle memory and retraining your brain to get it in the habit. 

 

Done and done.

@GD - It's a Pentel Graphgear 500, .5mm. I've had it for more than five years, and I love everything about it.

Tell us about this mechanical pencil!

I noticed this when building stuff earlier and started to use this technique....it is just a matter of training yourself to do something a little different. At least it feels different than 'natural' to me...in time, I hope it just feels natural.
