I have been using my virtual soapbox exploring the methods I use to layout dovetails. I have two strong opinions when it comes to dovetail layouts: One, its important theyre simple and straightforward to carry out, something repeatable and consistent enough to be easily repeated. And two, there is no "Unifying Theory of The Dovetail Continuum," no "One" way to do it right. As a designer and builder of fine furniture you should be versed and flexible in using several different layouts so you can use choose the right look for the right circumstance. Dont ever make the mistake of locking yourself down into one pragmatic view of your pins and tails. If youre just joining the conversation or want a refresher of where weve been already you can find all the dovetail layout posts collected together HERE. I believe yet one more Dovetail Maxim: Dovetail joints are meant to be created with a hand powered saw. Remove the waste however you want, but there is no replacement for the simple, straight-forward hand saw to create the lines that define the joint. I do not care if you have a whole chest of drawers in a dovetailed carcass on your plate, do it the right way. The only time you could convince me a router is the way to go is if you have to build more than fifty or so drawers in a weekend. Short of that, a Leigh Jig or other random router dovetail template is a waste of your hard earned money. So since we are doing the right thing and cutting our dovetails by hand, then why wouldnt you use that fact to your advantage. You are not a machine so you do not have to cut your dovetails like one either. Unless the design calls for subtle even dovetails that blend in to the background, why not add some pop with some staggered pacings and varied sizings. After all dovetails are the showoff of the joint world. They like to scream "Hey! Look at me!" So changing up the game a little can lead to some nice results that dont have to be distracting, but can instead showcase your artistry. The key is to remember the eye likes symmetry and grouping. I repeat my sizing from the right side of the layout to the left side to keep that symmetry. I will also group two or three smaller pins together with wider spaces between them. Groupings of more than three tend to begin to look busy and too many varied widths can look amateurish. I rarely do more than two or three different sized spacings in a design. Well executed simplicity will be more dazzling than complexity. Heres one way of accomplishing the type of layout Im talking about.
As we have gone over before, you can use dividers to help size the layouts, but I often find it faster to just use my chisels as sizing blocks. With the stock in the vise I mark my half pins on either side with a 3/8" chisel.
With that done I measure to find the center of my stock and mark it.
Shifting the rule over I then mark out for a 1" wide space. If I were to expand this across a wider section of stock I have the decision between widening this center area or adding a second area and spacing the board out in thirds instead of halves. Wider stock yet? I add more of the same spacing and judge the right amount needed by eye.
Then I grab the 1/4" chisel and eyeball the placement in the center of the remaining space. What no measurement? Thats right, you can measure if you want, but I think you should be able to trust your eyes to tell you what looks right. If it looks right now, why should it look wrong later? I just make a small mark on either side of the chisel.
And complete the lines with a small tri-square
I make sure to "X" out the areas to be cut away . . .
. . . and mark the angles on the face of the stock. I only bother to mark my end grain and the face of my stock. Marking the angles on the backside is unnecessary, and this way makes sure I dont get turned around and put the face of the stock away from me. I want any tear out from the saw blade to be on the backside of the stock and the inside of the joint.
Ready to start sawing with all the waste marked.
Transfer your pins, mark, and cut them. Often these days I will only mark the end grain on tails, but when I was starting to learn I would transfer my lines square down the face of the stock to help guide me.
After the joint is put together and cleaned up you can see how the paired grouping and slight variety in widths gives an interesting and appealing look. You can play around a lot with groupings and an asymmetrical / symmetrical look. Heres a quick second take with a different result.
This time I chose to start with very wide half pins, so I used my 1" chisel as a marker.
And I repeated it on both sides. Remember, use symmetrical placement of asymmetrical sizes and you can achieve good looking results.
Everything marked out and ready to cut.
And the finished product, a similar paired grouping to the previous set but with an altogether different appearance and feel. Consider the effect youre reaching for as you head into these layouts. And one more off the deep end just to prove a point.
With this joint I did zero layout at all beyond marking the appropriate depth of cut with a marking gauge. I didnt mark my angles or my spacing, and I actually tried to make it very random. While this is the ugly stepsister of the whole series, it does prove a couple points. One, is it proves how simple layout can be if you are practiced at cutting these joints. If I had put effort into symmetry over randomness I have no doubt I could have turned out a workable joint with no substantial layout at all. Just my eyes, my mind, and my hands working together in a practiced way. The other point is that from a design stand point, I can actually conceive of using this random joint as a design feature. Say I was making a box based on The Mad Hatter from Alice in Wonderland, or representing a twisted ideal in some other fashion. This joint would be perfectly at home in those instances. So understand the look youre going for and dont be afraid to make mistakes getting there. After all, those arent mistakes, they are lessons learned. The most important thing to remember is to relax, do NOT put this joint up on a pedestal, just have fun and go for it. Im pretty sure this should wrap up my side of this discussion. Thanks for lending me your ears while I rode the soapbox for a while. Cheers Oldwolf
