Grieving the loss of another Maker space

As of November 15, 2017, the TechShop – a world-wide network of Maker spaces – has declared bankruptcy and shut down. This is the second Maker space I’ve belonged to that has gone under in the past few years (the first being the Sawdust Shop).

For those of us living in apartments or smaller homes, these places provided both a physical space for creating as well as a community of fellow woodworkers. Knitters can bring a bag to a coffee shop, artists can bring a sketch book to a park bench, but woodworkers generally need a bench and tools (even hand tools) that are a bit awkward to lug around. Instead of fabric snippets or eraser dust that’s easily cleaned with a broom, we product sawdust and wood chips, the former being a nuisance if inhaled. Hand saws, chisels, clamps… as a bundle these weigh more than can be easily carried in one trip.

On top of losing a workspace, I’ve lost the gathering place of like-minded crafts people. We all grow through the give-and-take of advice and commiserating over mistakes (or “happy little accidents” as the art teacher Bob Ross used to call them).

I’m smack in the middle of building a drafting table for my step-daughter. To add insult to injury, half of my project is locked in a building that’s now in Chapter 7; I’m told we’ll be able to retrieve our possessions at some unspecified future date. I’ll be able to finish it at my dining table, but that’s a bit of an inconvenience to my family. I was planning on starting a jewelry box and another guitar this Autumn, and now I’ll be re-thinking how to establish a studio space at home.

That’s all for now – I just needed a place to share my sorrow. Perhaps later I’ll reflect on the economics of establishing a shared communal space in a high-rent community like the Bay Area.


Passing the point of no return

Tonight I joined the guitar top to the sides. This is a non-reversible operation, so if I messed it up, I’d be rebuilding a new top AND a new set of sides. Fortunately, it went relatively smoothly. I triple-checked the fit and alignment, did a little last minute trimming of a couple of braces, dry-fit the clamps before gluing, then pulled the trigger. Below are the before and after pictures – tomorrow I’ll unclamp everything and see how it all looks as a unit.

I feel like I’m on a bit of a roll now – a lot of design decisions have been made and committed to. Now it’s “just” about careful execution. I’m going to try to keep up at least weekly work on this through the holidays, when I’ll have a more concentrated span of time for shop work.

If at first I don’t succeed…

After fixing the guitar body lining that I messed up in my last post, I went back to the shop today (fueled up on delicious Thanksgiving leftovers) determined to slow down, get in the zone, and cut the notches in the lining they way they should be. In the end I decided to try notching the braces into the lining for structural reasons, not acoustic reasons. The acoustics, as I mentioned in that post, are a matter of debate – how tightly coupled the back and sides are to the top is a matter of taste and tuning. But I’d read stories of braces coming loose over time and vibrating – supporting the brace ends by tucking them into the lining seems to help, and that explanation made sense to me.

A few careful saw cuts and chisel strokes later,

I had six pockets routed out on both the top and back sides of the lining. A preliminary fit of top and back showed I was in the ballpark – I may have to trim a smidgeon here and there before gluing, but that’s better than removing too much all at once. There will be a little but of ugliness in terms of the visual presentation (in some cases it was easier and safer to just remove two whole segments of the lining to the correct depth, rather than try to saw and leave a very thin and weak segment), but most of this work is not visible to casual inspection. Again, “just build the damn thing.”

No particularly deep lesson today, just a reminder that failure is an opportunity to learn and grow. While I lament the fact that there is no easy “undo” in woodworking, it does slow me down and focus my concentration in a particular way, and gives me real “failures” to recover from.

Trying the NaBloPoMo exercise, 2014

My colleague Cynthia tells me that it’s National Blog Posting Month (NaBloPoMo), whereby we take up the challenge of posting once a day for the month of November. I have mixed feelings about this – do I really have anything worth saying/writing every single day? Well, this is one way to find out.

On the guitar building front – slow progress. I’m treating the body and the neck as two entirely separate build processes until the final assembly, and I’m glad I chose that path – having to integrate design choices for both body and neck simultaneously would have been overwhelming. The key parameter – the angle at which the neck meets the body – can be deferred and actually adjusted after the fact (to a degree, and about one degree is about all that it will take). Some quiet evening I’ll glue in the other set of lining strips, and then start the finishing work on trimming the brace ends and notching pockets in the liners to accept the top and back palates.

As I discussed in the past couple of blog posts, the process of working through the guitar build has been very different from crafting a symbolic work (an essay or computer program). Mistakes due to poor planning can be costly setbacks. This is another reason I’ve set the neck aside for a bit – I realized that, even on a rainy Saturday afternoon, I can’t simply go into the wood shop and “work on my neck.” I really have no idea what I need to do next, and before I take blade to wood I really need a plan.

If the neck were a piece of software I might try one or two different approaches (true up the sides first, then the figure out the right length and cut the body end square; or work on the heel first, and worry about the sides of the neck later?) If i didn’t like how one approach was coming out, I’d simply back out the process (“undo” the changes) and try another approach. Obviously, that won’t work with wood. As it turns out, I do have two necks to work with (the first had too many chips and flaws in the headstock, so I’m using that as my “rehearsal” neck), which gives me a bit of an opportunity for a “do over”, but I don’t want to squander it. If you knew you could only press the undo button once on a project, how would you approach things?

So I’ll stick with what is on my proximal horizon, finishing up the body. The logic and sequence of what comes next makes sense to me, and I can play around a bit with those choices.

Other themes I may write about this month: on the music front, I’m taking up Bach’s Chaconne seriously. I’ve doodled with sections in the past, but many of the passages (particularly the fast scale work in 32nd notes) have been beyond me technically. The Chaconne is really a rite of passage for serious classical guitarists, and is the piece my old teacher and I would have started working on next when I was graduating college. Working on it will provide a good vehicle for working on my technical weaknesses; I’d prefer to work on scales in the context of a musical composition, rather than as stand-alone exercises. And the Chaconne is simply beautiful.

On the work front, I’ve felt a bit like Cassandra this year, doomed to tell clients that their brilliant ideas are probably not going to work out as easily or well as they think, and then working on evaluations that prove me right. While I care about “making a difference” in education writ large (and what that means exactly will probably be the subject of many NaBloPoMo musings), I’m generally skeptical that the problems that matter call for technological solutions, at least in the limited “how can we substitute a computer for hands-on instruction” sort of senses that dominate the field.

This year has also opened my eyes to the inner workings of the medical profession, mainly by watching my partner go through some significant diagnostic challenges. If I can write about those insights while protecting her privacy, I will.

Well, perhaps I will after all find enough to write about this month. In the past this effort has petered off after a few days; to keep it going I’ll have to make a regular habit of writing before bed or at another set time of day.  Till next time!

Perhaps not bad, but different habits

In my last post I ruminated on some habits of mind I’ve developed over the years that are not serving me well in guitar building. In software engineering or other “symbolic” construction activities, we can undo our mistakes with a keystroke. Writing a paper is a bit like shaping bits of wet clay into a form; revising and editing is like shaping fine details. If we don’t like how something is coming out, we can scratch it out and re-do it.

In woodworking and other crafts, there is no undo button. Recovering and re-working a mistake can be quite time consuming. As I continue my guitar build, I pass several points of no return. If I take too much thickness off a side or plate, I have to start that piece over. If I bend a sharp kink into one of the sides, it’s unlikely I can un-bend it smoothly, and have to start from scratch on that piece. Once both the top and bottom are glued to the sides, there is no going back to tweak the interior bracing. The real hold-my-breath moment will come when I’m trying to fit a finished neck to a completed body – if I take too much material out of that joint while adjusting the angle, I’ll have to build an entire new neck.

Guitar making calls for a particular set of mental work habits. Critical among these is careful planning and execution of individual work phases. But that doesn’t make the way of the software engineer “bad” – rather, it’s an inappropriate set of habits for the job at hand.

Modern software engineering paradigms depend upon rapid iterations of design-implement-test cycles, with lots of throwing-out-and-redoing of code. See, for example, Agile Programming philosophy.

Professional software engineers have reflected on how programming lies somewhere on the span between art and engineering. In the arts, the creator is in constant communion with the medium, be it a canvas, manuscript, block of marble or code module. S/he works toward a goal, but there are always opportunities for the work to reflect back “hey, I’ve got a better idea!”  Good artists listen, appraise, and change direction in response to new revelations. Agile programmers follow a similar process with respect to both their discoveries along the way and the changing needs of their clients.

Woodworking can sit in varying spots of this spectrum as well, in some cases being more linear in process (think building a house), in others smack up against the arts end of the scale (starting with a chunk of firewood on a lathe, and ending up with a bowl). In the case of a guitar, there are strict constraints on certain design elements – the frets have to be spaced just so to produce well-tempered intonation (but see the fan fretted guitar for a clever innovation – retaining the relative fret spacing string-by-string but scaling each string to a different length). But there is also wiggle for late changes; on my current guitar, I’ve decided to alter the original plan for the neck-body joint. Rather than use the classical Spanish heel, I’m designing a bolt-on neck joint. Totally non-traditional in the classical guitar world, but this joint affords a lot of fine-tuning at a critical phase of construction (getting that angle right). For a relative novice luthier, having this flexibility is a gift – I don’t have to get everything “just right” several stages in advance, only to discover weeks or months later the critical mistake that has killed any chance of getting a playable instrument from the process.

The bottom line:  I’m not “bad” for needing to learn a different set of work habits when I close the laptop and put on the shop apron. These different habits of mind serve well under the appropriate circumstances.

Taming bad habits

I’ve been making slow, sporadic process on guitar #2, but the past few weeks have seen a burst of activity. The sides are bent, the top and back plates are braced, and I’ve just finished sanding a contour into the top edge of the sides to mate with the slightly domed top plate. Next up: glue the kerfing (liner) around the inside of the sides to provide a gluing surface for the top to adhere to.

Today I also shaped and scalloped the three transverse braces across the back plate. I noticed that one of them did not have a perfect 90 degree angle between the bottom (where it glues onto the plate) and sides – it was canted over slightly. But the braces end up trimmed in sort of a cathedral or triangular cross-section, so I figured I’d correct that by over-trimming one side to bring the two sides into symmetry. That worked, more or less, but then I found myself rushing the process a bit, having to then stop and fix some of the unevenness with sandpaper… all in all, it felt rushed.

A local guitar maker (a retired hand surgeon) once told me that building a guitar is like performing surgery: if you are careful in executing every step, you might get a good result. But if you rush or are sloppy anywhere, the probability of success drops off rapidly. My biggest problem is not getting into that Zen, slowed down, in-the-moment space before setting down to work. Today I was able to more or less recover from working too quickly, but it was a warning. My next moves have to be done with greater care – as the build progresses there is more and more to lose if things go wrong.

So much of my work in software was at a much higher tempo, in part because one can always “undo” mistakes with a keystroke. Woodworking – like surgery – requires a much more deliberative pace. I’m clearly out of practice with this habit of mind.

Committed to #002


I built my first (and only) classical guitar during my senior year in college. I’ve been feeling the itch to tackle a major project lately, and playing some high end guitars at local shops inspired me to take a second crack at it (having presumably learned something since my last attempt).

Since my last build, the Internet happened. Now I have access to several luthier forums where amateur builders can trade tips and tricks. Several amateurs have started their own web sites where they meticulously document their project (I don’t plan on being one of them, though – the market is saturated with those photo essays, and I’m more interested in documenting the inner journey). One professional luthier – J. S. Bogdanovich – has published a book, DVD series, and most importantly, full size blueprints of his design (my annotation of his top appears above).

So I’ve pushed the button – my wood is acclimating to the local climate, and I’ve purchased some of the specialized tools needed (e.g.,  an electric bending iron). Most of the work will take place at The Sawdust Shop, although some of the detailed hand work could just as easily be done on my dining table.

I’m hopeful that this will also kick start another round of blogging. A recent Facebook post by an old college friend mentioned a mid-life career crisis, and I was shocked at how many of our mutual friends chimed in “me too.” There is something about approaching 50 that makes one (or at least, me) take stock of what I want the next few decades to look like. Working with my hands brings me to a state of flow that I find hard to achieve otherwise; we’ll see whether any useful insights come from this next project.
