For me, finger joints have always been the nerdy, square cousin to the dovetail.

Finger joints are immensely strong when glued properly. But they are usually used by beginning woodworkers in places where a dovetail would be more appropriate, such as on a piece of 18th-century casework.

Add to that the fact that finger joints are tricky or dangerous to make on wide boards (without a commercial jig) plus the fact that gluing them with yellow glue is stressful, and it’s a wonder that anyone uses them at all.

And so we decided to tackle finger joints for the Summer 2008 issue of Woodworking Magazine, which will be shipping to subscribers next month. It took us a few months to really pin them down (pun intended), but I think we nailed it (and no, cut nails are not involved).

Here’s a small taste of some of the problems of the joint we solved after three months of testing in our shop:

Finger joints are a product of the machine age. Using them in styles before circa 1900 is just wrong to the eye. So consider the joint for more contemporary pieces only.

Cutting them Accurately: Right now there are basically two different ways to cut the joint: A shop-made jig for the table saw for narrow boards, and using a router jig that costs several hundred dollars for wide boards. We set out to develop a simple and safe shop-made jig that could handle both wide and narrow boards. Senior Editor Robert W. Lang had a stroke of genius on this and solved the problem forever (in my opinion).

Gluing Them Easily: You can assemble small boxes with finger joints fairly easily when using yellow glue. But at a certain point, you hit the wall because the glue sets up before you can close all the joints. So the solution would seem to be a slow-setting glue. Well, that’s one way to go about it. But we found an easier and faster way that is super-strong (see the photo of Managing Editor Megan Fitzpatrick’s boot on a sample joint). In the end, it took an anvil to bust up our sample joints.

Also in the Summer 2008 Issue

The finger joint is just one of the major themes running through the issue. Here are some of the other stories you can look for in the coming issue:

Building a Better Chest: Most woodworkers build chests using the most convoluted and fussy assembly imaginable. After reviewing hundreds of historical models, we settle on a method for building a chest that looks more complex at first glance, but actually saves an immense amount of shop time, requires less fussing around and allows more design flexibility.

Crackle Finishing: Many woodworkers who try a crackle finish have inconsistent results. Sometimes it works; sometimes it doesn’t. And predicting how much it’s going to crackle is almost impossible. Senior Editor Glen D. Huey cracks the code of crackle finish and finds out that the easiest and most predictable way to do it is also the simplest.

Trimming End Grain: When you have to cut back some end grain so it’s flush with some face grain, it’s always an opportunity to mess up the project. We show you two (actually three) methods for doing it right every time with a block plane, sander and pencil eraser.

And one more thing about the Summer 2008 issue: This issue is going to be mailed out to subscribers in a protective plastic bag, which will reduce the chances that the postal service will mangle it. If the plastic bag works for you, let us know so we can encourage our manufacturing division to continue using it.

And if you’re not a subscriber, you can easily remedy that here.

    Chris where are the instructions on bending the hinges for the sea chest? I don’t see them in the blog.

  • J.C. Collier

    I’m just glad to know that wasn’t Chris’ foot in the boot. I mean, how does one saw in heels? Hmmmmm…


  • Chuck Nickerson

    Megan’s boot crushing a wood joint…
    It’s either a promotional poster for "Wives Against Schwarz" (WAS, scarily enough), or it’s a disturbing step beyond tool porn: shop porn.

  • Alan


    I see you made a typo…isn’t that an Anvil Shaped Object? (ASO) *gd&r*

  • Norman

    Apologies to Megan, by the way. It’s really a lovely boot.

    PDF subs are good to offer, but I’ll wager most people end up printing outm many of the articles anyway. Unlike readers of, say, a general interest mag., who may read articles online without printing them, I suspect readers of an instructional mag like PW or WM will want to take the articles with them into the shop.

    We all want to do the right thing, but this green thing is a lot more complicated than it looks.

  • Christopher Schwarz


    We welcome woodworkers of all stripes and with all sorts of tooling into our shop.

    On the pdf subscriptions… they’re coming.


  • Craig

    I agree the plastic bag isn’t the best option, but we all expect to receive our magazines intact. If people are worried about the environment, maybe you should offer an online subscription version (PDF).

  • Samson

    It all sounds good. About the wrap: glad to hear it as my first subscription issue came pretty beat up with bends and creases and crumples.

  • Norman

    About the photo: I thought either Schwarz had taken up flamenco dancing, or someone let a dominatrix into the workshop.…

  • Don B

    I’m surprised you didn’t list the third way to cut finger joints – by hand. After many struggles with hand-cut dovetails, I decided to back up and hone my sawing and chiseling skills on finger joints. I had almost instant success with the 90 degree angles everywhere, no tilting the board (or the saw) to hit the line. Marking the board is easier, too. I’m surprised more people don’t steer beginning hand-tool woodworkers to finger joints before dovetails – all the skills will transfer over, and you will have had a much easier time because of not having to chisel out wedge-shaped spaces, etc.

    I enjoy your blog and the magazine, and I’ve learned a great deal from you and your colleagues. Keep up the good work.

  • Christopher Schwarz

    The top photo is indeed disturbing, which is why I picked that one. My foot looks so boring….


  • Christopher Schwarz


    I hope this is only a temporary solution until we can add a protective paper wrap to each issue. While I am no fan of plastic waste, we’ve had too much spoilage when sending it through the mail.


  • Norman

    Chris, please don’t go down the polybag path. It means a lot of the bags will end up in landfills, and I’d rather see you spend the production and mailing costs it will incur on more pages in the magazine. Whatever minor scuffling the magazine gets along the way is small cost to pay for more info, IMHO.

  • megan

    I tried to talk them into stiletto sandals…but Chris wouldn’t let me expense a pedicure 😉

  • The Village Carpenter

    There’s something a little unsettling about seeing a high-heeled boot in the workshop.

    I’m happy to know that it’s not your foot. ; )

  • Swanz

    You’re right about the joint not looking good in traditional pieces.
    I always thought making the joint looked like too much hard work and would
    rather use a dovetail jig. I’m looking forward to the article.
