computer cabinet in knotty pine

25"Hx30"W. my first casework project.

casters (CASTERS?!)allow it to slide underneath a desk that has not yet been built (the monitor, speakers and control inputs will then sit atop the desk).

all the wire debris routes through an exit port in the back
cpu, router, printer and power strip enclosed in the bottom, right drawer holds 8,1/2"x11"paper neatly, left drawer various other computer debris
started with a lengthy glue up of 1x12 knotty pine boards from home center that were first milled down to 5/8" thickness on the planer to make for a light-weight feel
this was then carefully dimensioned and prepped for dovetailing the carcass
the main casework wasn't terribly eventful, though i should not have used such a wide pin in the middle of the work as the wood cupped outward there and created some small gaps.
drawer runner assembly
my first attempt at nested cupboard doors using butt hinges. this was by far the hardest part of the entire project
plenty of little knicks and dents throughout show this as very much a learning project :-)

boomerang dojo with todd and sons

A quick boomerang project with todd and his two sons ryan and grant - these were made from some mystery wood scraps; pretty light weight. half-lap joints and then a rough spokeshave shaping of an airfoil was sketched out. See on the unshaped one LE for "Leading Edge" and "TE" for "Trailing Edge".

The models below are meant to be thrown right handed, grasping with your thumb and index finger the lower right blade in the picture, with a slight bank off of vertical; snapping motion of the wrist. they actually work!

too bad i forgot the camera to take some footage of flying them down at the local park. alack some spear/sword making concluded shop time for the day

derivative of the ruler trick: the pop can trick

sifting through all the sharpening methods out there, you read about the "ruler trick" attributed to charlesworth (i think). that's the metod of honing a blade from the back side to help finish out a new edge using a standard 6" rule. works great but i dislike mucking up my ruler. so I tried using a thin strip of material from a soda pop can, folded along one edge to help it register along the edge of the stone. i've been using the same piece of aluminum for some months now, and have been satisfied with my results. not sure if anyone else has tried this out there, but today i took some time to show it off here.

after going through the typical progression of grits (my finest is a 8000 waterstone), i flip it over and then just a few light swipes on the back like so:

I usually do one more finishing swipe on the primary bevel (I do not use a secondary one...since i hollow grind, i don't use any jigs to hold the blade, it registers fine on the stone without), i go back to another swipe or two on the back side. hard to make oute here but there's a light polish near the underside's busy end.

works for me

a kitty tree in reclaimed redwood fencing

you can't teach cats. you can only give them options that they prefer over whatever it is you wish they wouldn't do. In our case, it is jumping onto the counter tops or shredding the couch.

We had one of those carpet wrapped "kitty trees" you get from the pet store, and while it worked it was filthy and unserviceable within weeks of use. at the same time, we have used these disposable cardboard "scratch pads" meant to be set onto the floor. Those work fine, but we feelt kind of weird paying $15 for one of them at the pet store. I wanted to put a simple construction together using the cardboard idea, while also giving them the height advantage to be able to look out the windows and keep tabs on the local bird population. Another climbing option might mean less time spent on the kitchen counter they seemed to like it okay

I based the design idea off of something I found googling around (and it can be yours for $435!):

Implementation was pretty straight forward. I started with two long sticks of redwood, bridle jointed at this angle: I then threw together some trays dovetailed in the moste expedicious way to hold things together. These were glued to the lateral supports using Titebond III, and a couple drywall screws for good measure. the glue is probably plenty enough, but screwing things together made the clamping process a lot easier. THere' was no real joinery between the two parts, just face glue, so they could move pretty easily even under full clamp pressure.

and then about an hour or two of cutting a bunch of 2" thick strips of cardboard, gluing them up to a thickness that will nest snugly into the tray frames. There were also some cleats I glued into the bottom of the trays to support the cardboard structure:

The lower stretcher is just a 2x10 with a few dados cut underneath to receive the "feet" of the structure. I wrapped some old rope to make a sufficient scratch pad.

quick picture frame in reclaimed redwood

Quick project here involving 4 sticks milled from old redwood siding that i've had drying out in my garage for the past 6 months.

Sarah found this 4'x6' map of california at the Oakland museum and wanted to spruce up our dining room with it. A tidy frame was on call. The choice of redwood is appropriate for the map, plus the wood is very pleasing to work. Its grain is very very fine. I'd estimate that this was old growth just given that the siding was quite beat up and had several layers of paint needing removal before final milling.

I used mitered bridle joints. wished I had a decent shoulder plane to help with the fitting

I chose a very subtle ornamentation for the corners, and knocked off the edges of the frame using a spokeshave and a smoothing plane.

The miters were gappier than I would like, but you can't see them from here.

a small box for ralph, and a look inside my toolkit

At my work, we've enjoyed a certain contractor gun-for-hire software developer to help shore up all manner of rats' nests in a complex environment. Ralph was above and beyond the call, and unfortunately my company is not going to re-up his contract, so next week is his last one for us. Anyway, I wanted to make a simple box for him to put doo-dads in. It's my first time with padouk wood. Love it's spicy smell and the striking red color that oxidizes into a brown over time: Its lid hinge is just a lateral wooden dowel affixed to the inside going right into the sides of the box, nothing fancy:

A fellow named Jeff asked about my Japanese tool box pictured in the previous post. I said I'd show a few details of that here.

The design is heavily influenced by Daiku Dojo. The impetus to get a tool box housing my tools precipitated from a lot of the buzz over the past year in the lead up and wake of Schwarz' The Anarchist's Toolchest. I bought his book and read it over a couple times and all I can say is that I respectfully agree with two essential points: a) you need an enclosure for your tools, and b) you can get a lot done with a small amount of them (just what fits in the chest).

I think a lot of people, myself included, got hung up on his use of the big "A" word and what "subversive" means. I suppose one can be subversive by not going to Ikea to buy a piece of furniture. but that's a fairly minor way of being an anarchist. That said: setting my tools out in the open air on my *gasp* IKEA shelves, was a cluttered mess that attracted dust, the bane of all iron tools, and a personal shame for too long! I salute Christopher Schwarz for his work regardless.

Looking over the pictures, it is also obvious that this chest is heavily influenced by the tool kits my dad and I carried to airplane competitions. The box develops over time, to contain the tools as you need them, arranged in a way that is very base-brained. One should be able to find a particular hemostat or tweezers, or glue, without even looking. In "the field", you cannot at all be wasting time foraging through your tool box for a particular item. One should be able to reach for a razor blade, or CyA glue, or piece of reinforcing balsa without thinking, eyes focused on the broken spar, or damage. Gotta catch that thermal brewing on the flight line. You know you have about 5 minutes until the next one develops. That's 300 seconds to load a balsa fissure with super glue, install a new motor into the fuselage, wind the timer, and walk out to your winding stooge, and launch pylon for a new attempt where your flight judge is waiting with binoculars...oh I drift back to those years.

Anyway, here is my kit. I used a bunch of reclaimed redwood fencing from my favorite architectural salvage site, Urban Ore. Ran the wood through a planer and ended up with 5/8" thick planks that I edge jointed into a box whose LxWxH is roughly 45"x14"X14". Held together mostly with nails and drywall screws. I repurposed Sarah's old desk with particle board top (Schwarz has a good term for particle board: "Termite Barf"). This desk elevates the chest to about bench height, and then I put this all on casters. The casters are great. You have a portable tool tray where things can be set without cluttering the bench top. They can be easily repositioned around your work with minimal effort, they are always at an arm's reach and yet out of the way. The rolling service desk idea came from a surgeon who commented on Schwarz' blog and I cannot agree more with the utility of such an approach in an operating room, having been the recipient of much surgery over the past decade or so:

I borrowed heavily from Anarchist's Toolchest in setting up the interior. Two sliding trays of increasing depth allow me to separate my tools into groups that are sensible to me. Measuring stuff is low profile and always at the top, followed by my beloved few knives and chisels, and marking guages. Then the planes and saws at the bottom.

I'm content with the housing for the few hand tools I have. There are not a lot, but the ones I've got get me pretty far in my work. I can lift the box and carry it around fairly easily, although the cargo weight is biased towards cast iron planes which has in turn piqued my interest in wooden body planes.

I close with an excerpt from Toshio Odate's excellent book, and his brief comment on the toolbox: “Note that the toolbox is nailed together. The Japanese are especially careful about the joints in their work, and are, in fact, noted for the skill and beauty with which they create these joints. But While the dovetailing and other joinery in a cabinet may reveal the shokunin’s care, the drawers in the cabinet, like the joints in the toolbox, are nailed.

An American craftsman pointed out this seeming contradiction to me, and I had no answer for him, so natural did the use of nails in drawers and toolboxes seem to me. Yet, on reflection, I believe that the sight of a shokunin carrying on his shoulder a beautifully painted and carefully joined toolbox without nails would provoke me to an overwhelming sense of awkwardness.”

entryway bench in reclaimed douglas fir

we wanted a bench for our entry room to keep the wall company. a plane bench and a plain wall. Sarah was happy with it and in the end that's all that really matters. The wood originated from Urban Ore...some rough 2" roughcut fir that looked like it was used in a foundation...it had a lot of concrete stuck to the sides and needed vigorous wirebrushing before the stark power of my Lee Valley Scrub plane. Originally I had tried doing some of the hard work with my thickness planer, but the neighbor complained about the noise and I was in no mood to get into a bad situation, so it was all hand tools here 75% of the time in this sort of a project is scratching your head and other body parts trying to come up with an idea on how to "design" something so simple. Lots and lots of looking at what other people do, knowing certain dimensions are almost invariant (18" is a good rule for height, give or take a thou). I suppose I could just have copied a design out right, but there are always certain factors in the way from me doing that. I like to draw and do it all the time at the office. just doodles while listening to people making noise with their mouths over speaker phones in sterile conference rooms. sometimes an idea or a shape will take hold and I will draw hundreds of variations on it...how should the legs look? How should they curve? How many curves are there? Then there's the sort of design that happens from working the material...in this case it's doug fir. the wood had a gorgeous ring density and I knew it would be pleasing once done, but while working it over with the scrub plane, it clearly would be a negotiation rather than a dictation, on how this piece was going to come together. The grain went all sorts of directions from the knots. I'm a sucker for knots. Here is how I keep track of the legs, the grain emphasizing a roundedness which will be important since these legs will be finger tennoned into the top Each step along the way increases the stakes in the project. I knew it would be important but I could not tell from my sketches on paper how I would resolve this joint in the finished piece. It took a lot of exploration with the plane, the spoke shave, a knife Turning over to work on the surface, I originally thought of this as a dished piece, cupping your posterior as you put on your shoes for whatever was next. but this is a hall bench and you don't want a cupping, cupping means you stay put, you want something to instead just be a temporary rest where you lace up, and then shove off...so a convex shape seemed to make more sense here...don't get too comfortable. various hand planes make this happen. Glue-up, each tenon split on my band saw for a wedge of some hard wood, pounded into position and making these joints for keeps I used tongue oil. It accentuates the grain and warms everything up, but also makes those wild fluctuations in the coloration of the wood more apparent. It's a matter of what you're into. I like my pizza burnt and am a little suspicious of those who dont
