For the Crucible Dovetail Templates, I think we’ve finally figured out efficient fixtures for workholding, allowing us to cut more than one tool at a time on the CNC mill…and when I say “we” and “us” I mean our genius machinist, Craig Jackson. So, we finally got in a large-ish batch, and they are now available in our store.
The Crucible Dovetail Template marks out dovetail joints – both the tails and the pins – and allows you to easily and accurately lay out the angled and straight parts of the joint. This template marks out the two most common dovetail slopes, 1:6 and 1:8 (9.5° and 7.1° respectively).
This solid steel template is based on a discontinued version from Woodjoy Tools. We contacted the designer, Glenn Livingston, to obtain his blessing for our tool, and he receives a royalty on every one sold.
Unlike the original, the Crucible Dovetail Template is milled from one piece of steel, which ensures a perfect 90° at the corner. (While this might seem wasteful, all the excess is recycled.) The tool measures 5/8″ x 1-11/16″ x 3″. The angled sections of the tool are long enough to mark out tails in 1-3/8″ stock. The straight section of the tool is long enough to reach fully across two 3/4″-thick boards (for those who gang-cut dovetails). There’s also a handy hang hole, just like on the original.
The Crucible Dovetail Template is made in Kentucky.
If we had a company motto, it would be something like this: “If it were easy to do, then every idiot would do it.”
It’s something we say to ourselves when we’re fighting to find enough cotton cloth for a run of books, or a vendor for hinges for our dividers, or looking for damn Chicago screws without a burr on the underside of the head that has to be machined off and who does that and why am I not able to finish this sentence like a normal person?
And so we look to Craig Jackson for salvation.
Craig is the machinist we use for a lot of parts. He’s like if Matlock and Columbo had a baby. He’s easy to underestimate because of his Kentucky accent, and you do that at your own peril.
Anyway, for the last few weeks, we’ve been wrestling with the tips of our Crucible dividers. They have been getting bent in transit, and we’ve tried lots of strategies to stop the damage. All through the process, Craig kept saying: I can show customers how to heat-treat the tips at home.
But we ignored him. At our peril.
Finally, we came up with a solution with the CNC mill that would strengthen the tips. Craig said it would work, but he also sent this message:
“Heat treating the tips now.”
OK, because we live in a litigious society I have to say: Don’t do this, you fool. It’s a joke. You will hurt yourself badly (but please tell us if the tips increased in Rockwell hardness).
Two of our new sliding bevels, plus a early design prototype that Josh Cook printed out.
As a chairmaker, a small sliding bevel is essential to my work. The tool guides most of the joinery. It also is a companion when I explore historical chairs to understand how they work.
When we completed work on the Crucible Type 2 Dividers, designer Josh Cook and I wondered if we could adapt that tool’s ingenious tension/locking mechanism for a sliding bevel. The answer is yes. And thanks to tool designer and machinist Craig Jackson, we have a bevel in the works that exceeds any expectations I had for the tool.
The Crucible Sliding Bevel is unlike any other sliding bevel I know of. It locks the blade position so tightly that you have to be quite strong to get the blade to move off your desired setting. And if that’s all it did, I’d be happy. But it does something else, too.
Thanks to Craig, the Crucible sliding bevel has dual controls that allow you to do some helpful things. The screw up by the blade controls the rotation of the blade. It works like the adjustment mechanism on any sliding bevel. You can use it to lock the blade, loosen the blade or set the tool’s tension so the blade rotates but with some effort.
The second screw near the back of the tool is used to adjust how the tool’s blade slides in its slot. You can use these two screws to control separately the rotation and the sliding of the blade. That means you can:
Lock the rotation of the blade and then slide the blade to a different position in the body of the tool.
Lock the blade so it won’t slide, but it will rotate.
I know this might sound complicated, but it’s not. Much like the dual controls on the Tite-Mark, my favorite marking gauge, these become second nature within a couple minutes. Also good to know: You don’t have to use the dual controls. You can simply use the control at the pivot point to work the tool – bringing in the second control only when necessary.
Some of the many tool bodies that we experimented with. The colors in the backgrounds of the engravings is marker or metal dye – just experiments. The No. 11 is because this tool is our 11th tool.
Some Specifications
We are making the bevel in alloy steel with a 4″ blade, which is my favorite size. The blade is 3/32″ thick, so it is impossible to mangle. The body of the bevel is 11/16″ x 3/4″ x 4-3/8″ and weighs a nice 10 ounces. The bevels are being made in Kentucky. The control screws are the same size as the screw on our dividers (so perhaps we’ll make a screwdriver soon).
One of the other nice things about this tool is that it is extremely easy to assemble and disassemble. So we will offer a 7″ blade that fits in this tool’s body in early 2022.
So when will these begin selling? We are waiting on a large steel order. The production fixtures have all been constructed and the programming is complete. Depending on when the steel arrives, there is a chance we will offer the first batch right before Christmas.
And the price? This is the most complex tool we’ve made so far at Crucible, and there is a lot of milling to make the custom parts. The retail will be $200, and I think the tool is worth every penny. (As always, if you’re feeling salty about the price, I encourage you to give small-scale domestic toolmaking a go. I love it, but sheesh – making stuff is hard.)
I don’t know if we have enough margin in these tools to offer them through our foreign and domestic retailers. But a few months of production will give us that answer.
In the coming weeks I’ll make a video that shows how the bevel operates.

In the end, we went with an understated logo, which matches the look on our other tools.
The first batch of our new dividers are in the store and ready to ship. They are $110 plus domestic shipping.
These dividers are a top-to-bottom redesign of the tool. Lots has changed. They still work great, but they are built with a different aesthetic. Instead of being polished a near-perfect finish, these dividers are finished minimally off the mill. They are matte gray and there are small tool marks in evidence of how they were made. Our goal was to have the tool resemble what you would get from Stanley (or other top-line makers) in the early 20th century – not a custom tool.
But boy do they work well.
A special thanks here to mechanical designer Josh Cook and machinist/mad scientist Craig Jackson for figuring out how to make these just like we intended, and at an affordable price (for a small-batch U.S. manufacturer).
If we sell out, don’t despair, we’re making a lot more.
We began production of our Type 2 Dividers this week, and we hope to begin selling them in June or July.
As long-time customers know, we struggled to produce the first version of these dividers. They were beautiful. They functioned very well. But they were difficult to manufacture in great volume. While we were charging $185 per pair, we probably should have charged $285 or more because of all the hand-fitting and hand-polishing.
So we took the dividers out of production and have been tinkering with them for some time.
OK, so the next part of this story is what you don’t ever get to read when it comes to tool production. Many toolmakers are loath to credit the designers and machinists who figure out the nitty-gritty stuff. I want to give them their due.
Last year, we began working with Josh Cook, a mechanical designer and woodworker who was really interested in our original dividers. He sent me a pair that he’d made based on photos from our website. And we went from there.
Enter machinist Craig Jackson of Machine Time. You might know Craig as the creator of the EasyWood turning tools, which I love. After the EasyWood business was sold to another party and things went south, Craig went back to high-tolerance part production. But he loves making woodworking tools. So he took pity on me and now works with Crucible on some of our tools.
Together the three of us worked through a bunch of variables to come up with a design for these dividers that is:
Functionally perfect from the user’s point of view
Easy to make with minimal setups on the mill
Relatively inexpensive
The Crucible Type 2 dividers are new from the ground up. I can promise you that they have the same feel in the hand – like a heavy and smooth stone you found on a riverbank. Ever since we finished the first pre-production versions, I have kept a pair at arm’s length.
The hinge is completely redesigned and astonishingly smooth in use. While the pointy legs of the dividers are the most visible aspect of the tool, the hinge might be the most difficult part to design and manufacture. After I-don’t-know-how-many iterations, the current hinge is (here’s a technical term) sweet. Its tension is adjusted with a No. 8 screwdriver – something every woodworker has. You can set the dividers to move stiffly and hold a setting. Or you can lock them down to rabidly maintain the position of the points.
We also wanted to make these as affordable as possible while still making them functionally and aesthetically great. And make them in the U.S. with U.S. materials. The goal was a $100 retail – a little less than you would pay for a Starrett compass.
On Tuesday, Craig called me to let me know that they were cranking out legs for the dividers. In a few weeks, hinges will begin production at another shop. If we have any luck, assembly will begin in June and we will start selling them shortly after.
Thank you for all your patience. It won’t be long now.

P.S. I know that some of you are asking: Where is Raney Nelson in this? We parted ways amicably more than two years ago. Raney has evolved the design for the dividers to match his aesthetic. We have promoted his version many times on our blog this year and fully support his efforts at Daed Toolworks. If you are looking for ill will or grudges, you won’t find them here.
