Japanese Tool Box – Addressing The Lacunae

Of the inventory in the finished Japanese tool box there are several instances of absence.  Over the next several days/weeks/months/years I expect to acquire or fabricate the following for inclusion:

mortise gauge(s)

panel gauge

straight edge/winding sticks

layout square(s)

saw sharpening vise

plane setting hammer

bigger hammer

even bigger hammer

mallet

Many of these additions will be housed on the underside of the lid, the only place they could fit.  I will chronicle each of the fabrication projects here along with at least two planing boards.

New In The Shop – Scissors

One of the tools ubiquitous in most work setting is a pair of scissors.  Less common in a woodworking shop is a good pair of scissors.  Thanks to the evangelism of my pal Mike the upholsterer (thanks Mike!) I am always on the lookout for a good pair of scissors to add to the shop toolkit.  He has about 42 bazillion pair of scissors, each in top condition.

When I take note, it is surprising how often I grab for a good pair of vintage scissors to cut out patterns, make shims, or what not.

While at PATINA a couple months ago I was browsing through the tailgating flea market prior to the program and found a sweet, heavyweight pair in extremely good condition ($5 IIRC).  Once I got them in the shop and cleaned up they did not even need sharpening or adjusting.  The blades are six inches long and the action is smooth.

These scissors cut fabric, paper, cork sheet, leather, and lightweight carboard without breaking a sweat, and commercial veneers almost as easily (I use the veneers for shims, mostly).  Best of all is they do not take up much space.

So be on the lookout for similar tools for your shop and toss away the cheap scissors from the dollar store.  You will be glad you did.

Disassembling the Long Rifle

The process of taking apart the c.1815 David Cooley long rifle was one that I did not have the experience to undertake, so I called on my friend Tim who is both a rifle maker and a historian of the form and frontier life.  I’d invited Tim for a “look see” when I had the rifle in my shop the first time several years ago, and he appeared to enjoy the experience.  Since I was not confident of my understanding of how the long rifle was assembled in the first place, Tim was a natural call to make.

Much to my delight he was able to some in short order and set to work.  All the while he was scoping it out, and then disassembling the piece, he was providing a running commentary and I was taking notes as best I could.

A few of his observations were:

*the workmanship was superb and typical of late 18th century gunsmithing even though this gun was more than a decade after the turn of the century

*the gun had a “swamped” barrel, meaning that it as thinned slightly halfway down the barrel to reduce weight, a feature of the very best firearms of the time

*the hammer-and-trigger mechanism was a manufactured English set, probably purchased for Cooley’s inventory and ready to be put to use on a future gun.  Since the fitting of the hammer-and-trigger was crucial to the making of a gun, it would have been in-hand even before this gun was started.

*the barrel was also in-hand and may have actually been re-purposed from a previous gun or at least had been modified with a new tang welded on the butt end to fit the new stock

As the disassembly progressed I was very much impressed with the elegance and simplicity of the long rifle’s construction, and the fittings for anchoring the barrel to the stock were superbly made.  Tim took advantage of the opportunity to study many of the gun’s finer features, such as the spring loaded patch box.

One last observation from Tim was that he thinks the gun is still loaded, with the charge impacted in the butt of the barrel.

Many thinks to Tim for helping me out with a task I would have not been comfortable.  Watching him do his magic made me all the happier that he was available to help me out as there were steps I would have likely missed and damaged the rifle trying to disassemble it myself.

With the gun all apart I could examine the damage and set out on a path to make it as whole as possible.

The New Normal

Disclaimer — I am not now and never have been an ophthalmologist or played one on television, nor did I stay in a Holiday Inn last night.

Last Saturday, while vacationing in Florida to celebrate my mother’s 103rd (!) birthday, Mrs. Barn and I spent most of the day and evening in the Emergency Room of the Bascom-Palmer Eye Clinic in Miami, perhaps the nation’s leading institution of its kind.  The evening prior I had noticed a dramatic increase in “floaters” in my left (good) eye and during the night saw flashes of light also in that eye.  These are almost dispositive indications that a retina is becoming detached, almost being the operative word, and my concerns were pretty stratospheric.  Hence, the two hour drive to the clinic, the seven hour wait to see a doctor, and the two hour drive home.

Floaters are usually the tissue debris remaining from some physical disruption inside the eyeball.  They can be as plain as a tiny speck that moves around as your eye moves, essentially not a speck “in your eye” but literally a speck inside your eye.  I’ve had floaters of some sort virtually all of my life, but the number and size of this new batch had me concerned.  I had a new floater that looked like a Klingon warship, another that looked like a spider web covering about 1/5 of my vison field, and a multitude of tiny floaters resembling a swarm of bees, all of them bouncing around as my eye moved.  These last ones were the most concerning.

Floaters by themselves are not debilitating, but merely irritating as they are so spindly and translucent and do not disrupt vision in a meaningful way.  If I was a sniper it would be a problem, for a woodworker not so much.  But, I was experiencing a new type of floater I had never before seen, similar to a small cloud of fog moving around in the exact opposite motion as the particulate floaters.  That was very bizarre and disconcerting.  This (these?) were much like smudges on my eye glasses, only moving.  The problem is probably exacerbated by the fact that I have preposterously luxuriant eyelashes, so most of the time I have eyelash tracks on the inside of my spectacles with the resultant blurring to my vision.

Combined with the flashes of light in my eye, I was in fact experiencing the symptoms they tell you accompany a detaching retina and to get to the hospital immediately, so we did.  Having a base vision that is extremely myopic, about -12 prior to my LASIK, I was and reman at high risk for a detached retina.  Two of my siblings have already experienced detached retinas so my spidey-sense is quite high when it comes to this.

When we finally did get to see a doctor the eyeball examination was very thorough, and I was complimented on my cooperativeness.  And why not?  I’ve undergone a similar examination perhaps 150 times over the years.  I know where to put my head, how to hold open my eyes, when to blink, when not to blink, and to not be concerned about the tears coming out of seemingly every hole in my head.  (Hey, according to BC/BS I’ve had 22 eye operations and been fully asleep for only one of them.  When I put my head in the frame and am told to hold still while the doctor is closing in with a scalpel or a laser beam, I learned to hold still.)  Although I am certain I have shoes older than the doctor who examined me, I am experienced enough to know that he did an excellent job.

The bottom line is that I was not undergoing a detached retina but instead a detached viscera.  The viscera is the transparent protein gel that fills up the balloon that is your eyeball.  With age and genetics for some fraction of the population that gel begins shrinking and eventually pulls away from the surface of the balloon, releasing a lot of tissue debris in the process.  The phenomenon is accompanied by some flashing light in the field of vision.  So, I was correct to be concerned but my self-diagnosis was incomplete, fortunately.

My “new normal” for that eye is the presence of a great number of distracting floaters that my brain will eventually learn to ignore.  The cloudy regions, again not debilitating, are either the result of the changed optical properties of the viscera gel/retina interface or perhaps even the refractive index change in regions of the viscera itself, or they could be simply shadows of the floaters themselves.  All I can do is wait and see.

I have an appointment with my brilliant ophthalmologist in Charlottesville in a couple weeks.  It was a regularly scheduled appointment (I usually go four times a year), and after speaking to his post-doc yesterday I was assured that there was no immediate or urgent need for attendance.  I will know more soon, but it looks like this is just another thing to get used to.

As for my right eye, there is pretty much no reason for optimism there.  Two corneal transplants have failed to provide good vision, although I am told the “transplants look perfect.”  Not from my side they don’t.  Added to that was the subsequent cataract surgery resulted in a defective lens being implanted, so the vision in that eye is always distorted and hazy, like I am looking through a piece of plastic food wrap on a foggy day.  On top of all that was my glaucoma was not attended in a timely or diligent manner after it was diagnosed and not treated properly until the damage was mostly done, so I’ve lost approximately half of my vision in that eye altogether.

Now I wait to get accustomed to my new normal.

When my daughters were very young they asked me what I thought Heaven would be like.  I told them that for me it would be, in part, a realm where when I woke up, with my newly perfected body to fit this perfect place I could see the world around me perfectly.

I’ll stick with that.

 

One of These Days – Repairing the Twin Screw Vise

On my favorite workbench, a 35-year-old torsion box top with an Emmert, a wagonwheel, and a 48″ twin screw vise, due to mucking about with the twin screw fittings in the distant past and very heavy use for all those years, the iron collars had become loose and no longer were tighten-able enough for the vise to work.  Given that the torsion box top is about 90% hollow this made the repair a nuisance albeit a simple one to address.

I removed the vise, the screws are held to the jaw by split collars, and set it aside.  The screw collars on the bench came off easily as the screws holding them to the bench were all loose, hence the need for the repair.

With the receiving collars off I fitted some pieces of 1/2″ Baltic birch plywood to the back sides of the bench apron, a tricky task made problematics only because my fingers were almost the same size as the opening.  Using white PVA I simply glued them in place.

The next morning I fitted them to the round opening with a rasp, then re-inserted the retaining collars and drilled out the extant screw holes with a smaller pilot hole.  Instead of using the previous screws I switched to some 2″ #12 slotted screws I had in my mini-hardware store, screws I bought from Blacksmith Bolt and Rivet.

I carefully installed the new screws, making sure to not strip out anything, and installed the 48″ jaw.

It is now better than it ever was.  Another checkmark on the list.

One Of These Days… – Accessing My Hand Saws

About the same time I made the hanging wall “cabinet” for my Japanese tools I also made a similar cabinet for my hand saws.  It is fair to say that the second iteration of the concept was every bit as successful as the first.  I had this “cabinet” tucked into the corner above my Roubo bench.  Once again the cabinet door was so large (24″ x 36″) that almost everything (well, mostly the Gerstner full of layout tools) blocked it from opening fully, thus inhibiting the access to the inside contents of a dozen mostly vintage carpenter’s saws.  Plus, the combined inside depth was so shallow, ~4 inches, that I had to hang the saws flat inside, several to a peg.  That got real old, real fast.

The only part of the set-up that I liked was the holstered fittings for my back saws, which kept them visible and accessible.

So I pulled out all the saws from the interior and abandoned the “cabinet” on the wall.

Pulling out some scrap plywood I made two shelves to hold saws, one slotted for the top and one plain shelf for the handles at the bottom.  I attached these to the wall where my Japanese tool “cabinet” had resided previously.  The fit and location seem perfect.

I use the sides of the top shelf to hang surplus Japanese saws, and that arrangement also works very well.  I’m thinking that I will make a swinging panel on the front of the shelves to hang my back saws, but have not committed to that yet.  I have a bit more spatial arranging to do in the studio space before I get to that point.

Revisiting A Classic Long Rifle

In looking back over the projects of last year I realize that I never recounted my revisiting the classic c.1810 western Pennsylvania long rifle, made by well-known gunsmith David Cooley.  My previous effort was to simply stabilize it, but this time I got to dive in deep and repair it much more intensely.  Once I got it apart it was clear it had been damaged and repaired several times.

Here are a few detailed images to remind you of the exquisite workmanship of the tool.

Over the coming posts you will get the tale of making it more intact, not enough to shoot but certainly enough to handle and exhibit safely.   At issue was the through-and-through break running perpendicular to the length, right at the trigger mechanism.

Stay tuned.

Japanese Tool Box – The Trays

Rather than using the traditional tool rolls for any loose tools I decided to add two upper trays to the box interior.  One was dedicated to by bench chisels, or at least as many of them as I could fit in there easily, and the other for anything left over.

The trays themselves were made using left over pine stick from the box-fabrication, thickessed to ~3/8,” with 1/4″ Baltic birch plywood bottoms, all glued and pinned with brads.

To support the trays, which sit over the planes and are slightly cantilevered over the saw till, I glued and tacked thin support battens on the box wall and a divider of the same height between the planes and the saws.

I am likely to mount a few tools to the underside of the lid, like the square and other layout tools, but for now I’m calling this a former “one of these days” projects.

Japanese Tool Box – The Lid

Perhaps the most idiosyncratic feature of the Japanese tool box form is the lid, which fits and locks into place but is easily removable for accessing the tools inside.  The exact configuration of the fitting and locking arrangement is precise and fussy, and I messed it up royally.

The first step to fitting all of this together is to add cross battens to the tops of the box ends, and cross batten handles to them.  Many (most?) Japanese tool boxes have these handles flush to the end boards, I prefer them to be placed at the ends of the side boards such that there is a little recess behind them for easier gripping.  it’s just the incurable iconoclast in me.

The top slab fits underneath the top end battens and inside the box walls.  Like the bottom of the box, the top is a slab of hand planed <5/8″ pine, but planed to a whisper fit to the inside of the box walls

 

Then 3/4″ thick cross battens were glued and nailed to the top slab such that one end slides underneath one of the cross battens on the box top ends, then the top slides back underneath the other end batten to be locked in place with a sliding wedge.  Once again my trove of squared nails proved to be the treasure it is, as the soft nail shafts were easily crimped over without incident.

Being A COMPLETE IDJIT I attached the two lid battens in the wrong place, each shifted by 1/4″ in the wrong direction; I got the spacing of the protruding lips bass ackwards.  After much fussing and fuming and legitimate self-deprecation, complete with some impolite language, I had to trim 1/4″ off of the wrong end then glue it onto the correct end with white glue and bamboo pins.  It worked out just fine since it was not a stress-bearing function, but it was and remains an embarrassing learning moment.

Once I got all the fitting correct I added the traditional diagonal batten of 3/4″ stock.  This serves ostensibly as both another handle for sliding and removing the top and mitigating any tendency there is for the wide slab to warp.

Two cross-batten feet completed the construction of the box itself, leaving only the fitting of some interior features.

New In The Shop – Files and Rasps

When I was giving a recent presentation to the Richmond VA area MWTCA and RATS I was of course bound to browse the tool flea market and had some success.  My pal John Davis has acquired a goodly supply of NOS files and rasps and I picked up a couple from him.

At about the same time I got a pair of Nicholson patternmaker’s rasps and a pile of handles from Highland Woodworking in Atlanta.

These are valuable additions to the tool kit, and all of them are high performance tools well worth the space and expense.  I think the NOS files were a few dollars apiece, and the rasps were less than half the price of French ones and seem to be every bit as good,
