I'll be attending the Woodworking In America Hand Tool Conference next weekend in Valley Forge, PA. If you're in the area I invite you to stop by the Benchcrafted booth to see the Roubo bench that I documented here last year. This blog has focused more on woodworking than luthiery in the past year, but for those interested, I may have an oud with me at the show. Please stop by and say hello.

It's funny what happens when you can't sleep. I have a netbook on my nightstand, and when I can't sleep I check a couple woodworking forums, e-mail. When I'm bored with that (and I haven't fallen back asleep watching old episodes of The Woodwright's Shop) I grab a magazine from the lower shelf and read it again for the umpteenth time. Last night it was a Fine Woodworking from 1997. One forum thread was discussing a sale on Lie-Nielsen tools at a local Woodcraft. The topic turned to the price of Lie-Nielsen tools and how they've gone up drastically in the last year. So when I saw the above ad in the 1997 magazine I thought I'd do a little research and see just how much they've gone up in the past 12 years. The #4 in the above ad is priced at $225. Accounting for inflation (I used this calculator), this plane should fetch about $302 in 2009 dollars. The plane, in iron, is in fact less than this today. It sells for an even $300. But I was really shocked when I saw a similar ad (from 1998) for the L-N adjustable mouth block plane. Price was $150. With inflation, today's price should be $198. The plane sells today for $165. I like a good deal as much as the next guy, and using these two of L-N's most popular planes, a good deal they are indeed, since both planes have gone down in price over the years.
And it isn't just Lie-Nielsen. On the next page was an ad for (now defunct) Bridgewood Machinery. I bought a PBS-440W in 2006 (brand new, from Wilke, before the Bridgewood name was discontinued) for the exact same price as listed in this 1997 ad. No inflation calculator needed for that one.
I also did a comparison with a Grizzly shaper. The shaper (same model number G1026) from a 1991 magazine ad was $850. Today's price is $925.

It's been a little over a year since I finished building my workbench based on the Roubo design. In that time I've had the opportunity to build a number of projects with the bench, so I'd like to share some thoughts about how the bench has performed in the last year.
One of the first projects the bench saw was a cherry bathroom cabinet with a rather large single door. The sliding leg vise, which I built specifically for holding this type of work, did a fantastic job of holding the door for working on its edges and ends. The sliding leg vise is a beast of a vise when coupled with the stationary leg vise. It's huge capacity and raw holding power have convinced me that it was a wise decision to build this vise. The wood screws from Big Wood Vise have also proven their worth over the past year. They hold extremely well, turn very smoothly, and move very rapidly. I'm really satisfied with them.
The one thing I don't like about the wood screws on the sliding vise is the length of the hub. When planing the edges of boards held between both leg vises, it's a nuisance to step around the hub of the vise during the planing stroke.
The sliding leg vise is a trade-off. It's perfect when needed, but otherwise I want it out of the way completely. Most of the time I keep it stored on the shelf of the bench. I'm glad I made it easily removable-it can be dismounted in about 10 seconds.
I also made the back side of the bench so it can receive the sliding leg vise. This has come quite handy. I can slide the vise all the way to the left and in effect I'm left with a double-sided bench with leg vises at opposite corners. I keep my bench in the middle of my shop, so I can access both sides at all times.
What can I say about the wagon vise? I love it. I have yet to find a time where I've used it and been frustrated, impatient, or found it lacking in any way. It's met and exceeded my every expectation. I've only had to make one or two adjustments over the entire year. This summer I had to remove the dog block and take a couple shavings from one side to let slide freely. That's it. Wood moves as shop conditions change, and I'm quite amazed how the vise has handled the four seasons. The capabilities of the vise are quite basic. Clamp between dogs, or clamp between jaws. But its ease of use make it the best tail vise I've ever used.
This wagon vise (like any wagon vise) does not allow open-front clamping like a traditional "moving block" tail vise. I was a bit apprehensive about losing this capability. But in the past year, I've only moved to my old bench (which has a traditional tail vise) for its open jaw maybe half a dozen times. I was a bit surprised how little I actually used this feature, since I had imagined I'd used it much more frequently. I'd say that 90% of my work can be handled by a wagon vise. Nevertheless, I'll still keep a bench with a traditional tail vise for those other occasions.
Another project that put the bench through its paces was this large console cabinet. The project presented a lot of workholding challenges, and the Roubo came through with each of them. Removing the leg vise entirely makes for an uninterrupted surface at the front of the bench and allows an unencumbered work area for assembling this massive frame member. The stiffness of the top combined with the length of the top made joining this assembly rather enjoyable. My previous bench would have been a real source of frustration with this project. To get a better sense of scale of this project, here's the finished piece on my two saw benches.
The framework of the bench is built using drawbored mortise and tenon joints. After a year of use and 4 seasonal changes, all are as tight as the day they were assembled. The flush surfaces have moved slightly, but not enough to affect performance.
The open grain of the Ash was always a concern for the top of the bench. I've said a few times that I had wished I'd used hard maple for the top because of its closed grain. Yeah, I've had to pick out some stray metal particles from the Ash top, but I've only once run into a metal bit that caused me a slight problem. Nothing serious. In all, I'm really satisfied with the Ash. It's rigid as heck and very resilient. The latter point is a matter of debate, since it makes sense that a benchtop would ideally be softer than the project wood, thus allowing the bench to take the brunt of dings and scratches. Nevertheless, I'm satisfied with the Ash as a bench wood.
Even with the level of satisfaction I achieved with the bench in the past year, I've made a couple changes recently that have transformed the bench into an even better tool.
With the development of the Glide Leg Vise I've retrofitted the bench with this hardware. I was totally satisfied with the hardware from Big Wood Vise (and I still use it on my sliding leg vise), but the Glide has proven to be a real pleasure to use. It's fast, requires little effort to use, and has oodles of holding power.
Some people think that the hand wheels look out of place on such a traditional bench, since shiny metal hand wheels are more common to power machinery. First off, the wheel is a pretty old idea. Secondly, a hand wheel is a manual control device that lends itself to the movement of advancing and retracting the jaws of a woodworking vise (just like advancing and retracting a part of a machine like a table-saw trunnion or planer bed). Tommy bars are not very ergonomic, quick or pleasant to use, but they do offer a huge mechanical advantage by means of a long lever. If the need for a long lever is eliminated--by better engineering of the vise's holding capabilities--then the replacement of the less-ergonomic control device becomes possible, in this case with a better device-the hand wheel. I think the Glide looks fantastic on the Roubo bench.
By the way, using a hand wheel on a woodworking vise is not a new idea.
This is H.O. Studley's bench. He's more famous for his tool cabinet.
Getting back to the sliding leg vise. Most the time I don't need it. But occasionally I do need some support for long boards or wide panels when I don't want to mount up the sliding leg vise. So earlier this week I built a deadman.
The great thing about the deadman is that is stays flush with the front of the bench until you need to plug in a holdfast or clamp to secure the work. I built mine from 12/4 stock so it ended up extra thick-about 2-1/2". It doesn't need to be so thick, but I didn't see the point in planing away all that wood, or resawing. The extra mass provides lots of stability and weight, so the deadman slides easily.
The deadman engages the same slot in the underside of the bench as the sliding leg vise, which has a thicker rear section. I attached two cleats behind the deadman to engage the slot using some cap screws threaded and tapped into the deadman from behind.
I built deadman so it doesn't interfere with my benchdogs. So I can slide the deadman freely along the bench at any time and with the dogs in any configuration, up or down. I don't like things interrupting the flow of my work. The sliding leg vise has this problem, and I decided to fix it when I built the deadman.
The bench as it exists now is hands down my favorite tool in the shop. I love hand planes, but those only perform to satisfaction with a fine bench below them. If you're reading this, and considering building a new work bench for fine furniture making, I can't recommend this bench design enough. It has given me a renewed sense of enthusiasm for woodworking and furniture making, and I get pleasure and satisfaction from working on it every time I'm in the shop.
