Dog Strip and More Laminating

With the benchtop nearly complete, I had some serious decisions to make.  Actually, only one: square dog holes or round?

While there are pros and cons to each, I finally decided on square dogs for a few reasons:

  • Round dogs need to have some sort of spring device – be it a piece of metal, a ball bearing, or something else to prevent the rod from falling through the dog hole.  Eventually, this spring wears grooves in the dog holes and results in a less-than-tight fit.  Score one for square dogs.
  • Square dogs have flat faces, and there is no need to worry about turning inside the dog hole.  In addition, I have plenty of scrap maple laying around which will make for some nice dogs.  Point #2 for the square holes.
  • Aesthetically, the square dog holes are more prevalent in older (read, hundred-year-old) benches.  I kind of like this aspect, though it doesn’t fall into a functionality argument.  Final decision: square dogs.

Knowing that a Benchcrafted tail vise was on the way, and it should allow me at least 10-11″ of travel, I decided that I didn’t need a dog hole every 2-3 inches as some do on their benches.  I will be using legs that are 5″ square, and don’t really want to have a dog hole fall over a leg, so this means somewhere in the range of a 6″ minimum spacing between holes.  I actually figured out a good spacing on this, but don’t have that information available at this time – this post is probably 6 months after the operation took place.  I do remember that the first dog hole is approximately 3″ from the end of the vise cavity, then every 6″ (or so) from that point.  I made a template from 1/2″ MDF and scrap red oak which angled toward the vise at approximately 1-2 degrees off vertical, and used a 5/8″ template cutting router bit to create the cavities:

After making all sorts of noise and dust, I ended up with a completed strip:

Completed dog hole strip

My goal was a 1 3/4″ wide dog strip.  Each dog hole cavity was 1″ deep, and the SYP you see above was planed to 1 3/8″.  A mating piece which was planed to 3/8″ was glued to the top, the dog hole cavities filled on all sides with blue painters tape, and the gluing and clamping process continued.

Gluing the dog strip

As you can tell, there is about 10 pounds of glue which will eventually need to be planed off.  Nobody can ever say that I was stingy with the stuff; over a gallon was used on the top alone.

Coming up: initial flattening, front laminations, end cap, vise, and legs…

Laminating the Top

Laminating the sections of the top was a royal pain.  I had 4 smaller laminations of 5 boards each, which had to be face jointed and mated perfectly for strong glue joints.  This was where I really got an introduction to the jack and jointer planes, and where I also had the opportunity to make (and subsequently correct) plenty of mistakes.

Even though you would think that laminating five planks of pretty-straight southern yellow pine would give a pretty-straight face – it wasn’t the case for me.  The smaller laminations were almost universally bowed to some extent, requiring using the planes in an effort to flatten them for final glue-up.  Having no previous experience with this operation, and a head full of booksmarts on the process, I set out to prepare the sections.  Inevitably, this resulted in one outer board shrinking from 1 1/4″ thick down to as little as 3/4″ on each section – which translated to a fairly significant reduction in overall width of the bench.

Not wanting to laminate 20+ boards at once – mainly due to lack of confidence in my ability to finish within the 15-minute working time of the Titebond III – I thought the “smaller section method” would be the best way to go.  Looking back, I believe it would have been easier and probably given better results to have directly laminated a few boards at a time to an initial glue-up of, say, five boards.  Impatience probably got the best of me here; I don’t know.  But, yeah, if there’s ever a next time, I will glue up five or so, then add more directly to that initial lamination.

By the time all was said and done, I had a finished top that was nearly the required dimension.  I know that the typical sliding rules are the work of the devil, but measuring with a metric rule shows that there is probably a 1 or 2 mm difference in the width of the top over the entire 8′ length.  Not perfect, but certainly not terrible.  I can live with it.

It was sometime during this process that I decided to look into vises.  I was really attracted to the ‘wagon vise’ – a sliding dog block mortised into the top of the bench which allows work to be held a variety of ways.  Trying to engineer the setup in my mind was getting tiring until I read about the Benchcrafted Tail Vise.  An order was placed and preparations were made in ensuring the top would accommodate this device and remain within spec.  Thus, I ended up with three small laminated sections to glue up, a “correction” board of 1 1/4″ to make up for lost width which had a mortise routed into it for a planing stop, and another small lamination of 2 1/2″ thick to mate for the completion of the planing stop.

Time consuming, yes – but things were progressing.  Remaining are the dog strip, end cap, front lamination, legs, stretchers, and a bottom shelf.  Near this point work came to a near-standstill as we began tiling the house.  This was a grueling 4 months which I will never repeat – but that’s another story!

Best Regards,

The Beginning

Once I decided that the new bench would be the Roubo-inspired design from Mr. Schwarz’s book, I took time to map out what would be required.  Living in Florida, Southern Yellow Pine is cheap and easy to come by – so the wood species was a no-brainer.  A 4″ top sounded stout enough for anything I could throw at it, and I knew I wanted a full 8′ bench which was as close to 24″ wide as I could make it.  Numerous trips to home centers later, I had enough pieces of 2×10 SYP to start ripping into 4 1/8″ wide pieces to be glued.  I left these in the garage for 1-2 weeks to acclimate (the moisture meter actually showed that they were pretty close upon arriving at home – so I figured minimum of a week would be good enough to get started).  My garage is not climate controlled in any way, which means that summer temperatures of 90+ degrees and 80-90% humidity will take the life out of anything – including pine – in very short order.

Initial stack of SYP waiting to be glued up

Even getting to this point was tedious – I had to build a set of infeed/outfeed tables for the table saw, move things around in the garage to make room for the cut wood, and do all sorts of other non-enjoyable things just to get started.  The final place for the bench will in dead-smack in the middle of the garage, where I can move the bikes out and have plenty of room to work on all sides of the project at hand.

Rather than glue up the entire top at once, I calculated that four sets of 5 boards which were planed to 1 1/4″ would give me a width of 25″.  Fortunately, I have learned the foolhardy ways of thinking that projects like this can be calculated – my original plan should have been to take things one step at a time to arrive at the destination, but I like to envision the end result.  Mistake #0.  The first lamination went fairly smoothly, except for a minor glue mess.  I’m not sure if I used enough Titebond III, but it should hold just the same.

The first lamination

Lamination number 2 went together as well, but with more glue:

Second lamination for benchtop

Starting with the second lamination, my method of applying glue changed from “put a bunch into a pan and brush it all over the wood” to “just pour it directly on the wood from the gallon jug and slather it all over the place with a foam brush.”  Interesting point: once Titebond III glues on sealed concrete, a steel floor scraper is very handy to pop it off the surface.  The glue will come right off, along with the concrete sealer.  This means that the “workbench project” will become “the workbench and garage floor re-sealing project.”

Also note the shavings from my first efforts at using a hand plane to ensure the faces of each lamination were flat and ready to be glued.  This was certainly a learning experience; I believe I ended up shaving off nearly 1/4″ of one side before saying that it was “flat enough.”

And… yet, another lamination:

Another lamination for the benchtop

All things considered, things went relatively smoothly up to this point.  Sure, there were plenty of uneven boards which I figured to plane down – but at least progress was being made.  We really get into the learning phase as the pieces come together, though – so keep reading, maybe you will be able to avoid some of the misery that has plagued me!

Best Regards,

The Need…

My desire for a real, “it doesn’t move,” workbench probably started years ago.  I didn’t know it at the time, but it was there.  Each time I would start a new project with my helper (a.k.a. Mom), much of the process inevitably took place on a piece of scrap 3/4″ particleboard resting on a pair of sawhorses.  No matter what I did, there was always some wobbling and the always-present need to have Mom steady the so-called bench while I cut, routed, glued, or performed any other step in the building process.

I actually had a workbench in the garage – actually, it was a ski-tuning bench that I asked my Grandfather to build for me back in the early 1990s.  This was no more than two jointed and edge-glued southern yellow pine 2x12s that he probably found as scrap at a construction site.  What made this unusable for woodworking was that a) it was a ski-tuning bench and was much too tall to be useful with tools, b) it was a swedish-style* trestle which was not solid enough to prevent racking, and c) I had no idea what a real workbench was supposed to be.

Ski tuning bench

Of course, the cramped quarters of the garage didn’t help much – two motorcycles and a bunch of individually boxed power tools meant that the ski-tuning bench actually stayed up against the wall and didn’t do much more than give me a flat area on which to pile assorted crap necessities.

In late 2010, when my wife was working nights, I purchased the Chris Schwarz book on workbenches.  I read it a few times, and daydreamed about how great it would be to have a massive bench which was useful and didn’t wobble all over the place like my particleboard on sawhorses.  In the summer of 2011, I decided to finally get with the program and build a bench.  This series of posts will detail, to the extent possible, my experience with this project.  Hopefully my mistakes will be of benefit to some other woodworker that is thinking about tackling a project of this scale.

* I have no idea if this is how they build benches in Sweden.  It’s basically a stretcher with a long tenon on each end and secured by large hardwood wedges (instead of pins) on the outside of the leg.  My uncle learned this style of construction while in Sweden, so in my family, this is a “Swedish style” bench.

Stay tuned…

How it started (It’s a long story…)

Published on February 4, 2012 by in Woodworking

I was fortunate to have grown up in a family of diverse interests.  Mathematics, ham radio, aviation, military, business, marksmanship, science, cooking, carpentry, billiards – you name it, someone in my family either made money doing it or had more than a fleeting interest in it.

For this article, my focus will be carpentry and woodworking.  Some of my earliest memories included helping the family build my Mom’s parents’ house – and by “helping the family build,” I mean my grandfather would hold nails up and let me beat them down into the deck with a hammer.  I can almost guarantee that the hammer landed on his thumb as many times as it did the nails, since I was probably about five years old, but he was brave enough to let me do it anyway.

Throughout my childhood, I would spend occasional weekends at my grandparents’ house in Otisco, Indiana.  Inevitably, those weekends would involve talking my grandfather into a project.  Looking back, I don’t really think he minded – he probably had fun doing them.  He was a retired master finish carpenter, but never stopped working.  I spent many weekends at their house, waking up early to go to the lumberyard, and watching him rip down 4×8 sheets of 3/4″ BC plywood on a tablesaw which had no safety devices of any kind.  ”You can use any of my tools, but never use this saw” was drilled into my head.  Looking back, he probably shouldn’t have said that to a ten year old standing in a room containing a bandsaw, a lathe, a drill press, some extremely sharp chisels, knife blanks, and… you get the idea.

Bookshelves, chairs, whatever project he was working on for a client, my train set – you name it, it was built there.  I can remember him having an endless supply of sandpaper and some sort of miracle collection of Minwax oil-based wood stain (“let’s try ‘Dark Walnut’ on this”).  To this day, I hate the thought of wrapping sandpaper around a piece of scrap 2×4 to hand-sand wood.

The background is not meant to regale you with stories of my late grandfather.  Rather, it is a reminder that we are often educated in ways that don’t require books, classes, or money.  I have received many of these lessons throughout my life from my family, and it was not until I became older that I realized the importance of them.

I used the lessons learned from my grandfather in some of my hobbies while growing up.  For example, I became a “car audiophile.”  I used (the wrong) tools to butcher wood (it was mostly particleboard), in turn allowing me to build different enclosures for subwoofers, rebuild the trunk of my car to house amplifiers, speakers, crossovers, relays, and all sorts of money-wasting toys.

Not until moving into my house did I realize that:

  1. I wanted to add ‘stuff’ like built-in closet shelving to replace the cheap wire racks.
  2. I actually had space to have tools and an area to work on projects!
  3. I needed to improve my building skills in order to produce ‘stuff’ that would not be utterly repulsive to anyone except (at the time) a bachelor such as myself.

This led me down the slippery slope of tool purchases.  First on the list was a new cordless set – one of the DeWalt 18 Volt packages with drill, cordless (!) circular saw, sawzall, and flashlight.  I used this set to build all kinds of stuff, but quickly realized the limitations of a cordless circ saw when cutting 3/4″ oak veneer plywood.

Crown moulding?  Need to get a compound miter saw, air compressor, and nailers.  Bookcase?  A biscuit joiner would be useful there.  What’s that under the Christmas tree?  Oooh, a new router.  I better build a table for that!

Of course, the list goes on and on.  I’m now working on learning how to use hand tools so that I can enjoy a peaceful hobby that doesn’t involve very loud universal motors and sharp blades spinning at 13,000 RPM.  I expect this section of the site will mostly reflect my exploration into this arena – and will start with my current project, a massive Roubo style workbench inspired by Christopher Schwarz’s book,  ”Workbenches: From Design & Theory to Construction & Use

If nothing else, I hope you enjoy reading about my progress on here.  Feel free to comment on any posts.

73 and best regards,
-Palmer
