Harvest Faire Blacksmithing Demonstration!

So this past weekend was gloomy and gusty and drizzly, but we managed to make some cash for the guild, and get some exposure, and even a few new members. The TBG website is located here, where I'm sure you can view lots of pictures, but here's one of John and I at the forge.


This brings up an interesting piece of technique that I'll share with you. I normally wear only one glove. The hammer tends to hit the metal, and if you're paying attention, you don't miss, and your hand doesn't hit anything hot or sharp. If you're not paying attention, then bad things happen, but you shouldn't be forging anyhow. The free, or "work" hand (my left hand in this case) hangs onto the work or a pair of tongs, and gets rather close to the forge fire. Hence the glove. Putting on a normal work glove for your hammer hand tends to actually reduce friction, and when I first started out I wound up flinging my hammer clean across the yard a few times before I figured this one out.

This does pose a problem for bystander safety.

Not wearing a glove, however, tends to put a nasty little blister on your hand after a few hours at the anvil.

Solution: Sand your handles nice and smooth, and warm them over the forge fire. WARM - not roast! Then apply a small amount of wax, preferably bowling alley paste wax, and you wind up with a very nicely preserved, and rather easy-on-the-skin handle. It's waterproof after this, and won't turn gray, and the wax tends to lube the high spots in the grain so that your skin can wiggle and slide just enough during hammering that you don't get a blister. Keep it (the whole hammer) waxed or oiled lightly with some boiled linseed oil, and you'll have a hammer that lasts a long time and won't chafe your delicate [Fe]male skin ;-)

On another safety/user-friendliness note: The red goggles make for easier daytime viewing of color temperature. It takes a bit of "getting used to", since the flames and the incandescent metal itself will look a bit odd, but you're basically cutting out all the blue and green light from the sun, which makes the red/orange/yellow quite a bit easier to see coming from the metal. What might look black in sunlight will show up as a faint glow with the goggles on. Also, they block UV and just having something in front of your face will block IR radiation, and they're dark enough that the bright white-hot of welding heat gets knocked back down to a bright orange and doesn't leave you with a floating BSOD in the middle of your field of view when moving back to the anvil for a forge weld.

So, get a bunch of gloves, and find someone with an opposite dominant hand, and split the pairs with 'em. Then go to Harbor Freight and snag a pair of their red safety glasses. A pair of flip up welding goggles would be good too - especially when working in a dark area where you're not light-adjusted.

Have fun, be safe, and come to the next demo!

Cane Sword Update!



Here's the test-wrap for the hilt of the cane sword. 1mm and 1.5mm leather cord over poplar. Poplar will likely be stained with black India Ink. I may go with a more subtle reddish hue and back up the punched silver pommel with copper instead of onyx.

We'll see which looks best. I got some black sculpey and a couple of brass fittings so I can do some mockups - expect forging photos over the weekend!

Cane Sword Project


Here's the latest, and hopefully the last, revised render of the cane sword that I'm making for the upcoming independent film Terra.

Hand forged, clay-tempered blade, steel fittings with silverplated pommel and one-piece steel guard. Black lacquered aluminum sheath/cane, and leather cord-wrapped grip.

Watch for more scene previews and a revised trailer for the movie!

Closeout Sale! Million Dollar Man, now only $20,000!

So, here's an interesting Reuters video.

Paraplegics can now walk, thanks to a robot.

Take that, traumatic spinal cord injury.


Meanwhile they can drop their service dog off at the Pet Olympics, and enjoy a fine dinner strapped to a safety harness 50 meters up in the air.

True Mechanical Beauty

Here's Jay Leno preserving a bit of history, and one of the more beautiful pieces of technology that I've seen in a while. These cars are fuel efficient and clean - and they don't have a transmission!

First Response

So today I enter the world of non-facebook blogging.

I guess I should start out with a bit of an introduction:

*deep breath*

I am a patient advocate specializing in Disability Represenation before the Department of Health and Human Services, namely the Social Security Administration (SSA).

I am also an ad hoc consultant, in areas ranging from (naturally) disability and administrative law to biomedical devices. Sooner, rather than later, I'll be incorporating with a partner, but as it stands now, I'm just Wet, while WetSpark Consulting, LLC, waits for the Spark to get settled.

I'm also an amateur blacksmith and founder, meaning I can beat senseless, or nearly incenerate, just about anything until it turns into something pretty.

The only things off limits in that department are, naturally, radioactive elements, and a few refractory materials whose melting points require an arc furnace or some variation on Fe2O3/Al Thermite.

Further areas of interest, more on the amateur, or "as needed" basis, are ballistics and pyrotechnics, primarily in the vein of model rocketry and so-called "Spud Guns" or "Potato Cannons", as well as microcontrollers and other forms of digital and analog control and interface devices.

Currently on the drawing board are a few projects including two that just migrated to full "under construction" status. The most prominent is a small projector that aims to perform rather alot like the new Texas Instruments Pico Projector, but at a much lower (think fractional) price point, with equal or better performance.

The second project is the aforementioned "Potato Cannon". As with anything I do, I have aimed for perfection, and swung for the fence. Luckily, I've made solid contact with the ball, and we'll have to see if the outfielders can grow a few inches taller and snag this one from just over the fence.

I'll leave you with this, and post a more detailed blog about it later: Picture a standard propane powered potato cannon. Add a computer controlled fuel injection system, bolt action and an automatic chamber ventilation system, muzzle brake, and integral bipod and shoulder rest.

This is part of a project that includes a few other props for an upcoming independent film. So far the cannon itself may or may not actually make it "on screen", but the Damascus steel cane sword I'm forging this weekend most certainly will.



Check out the soon to be reshot first-run trailer for Terra, here.

That's all folks. I'll continue my epic saga of bringing my clients one day closer to tomorrow, tomorrow.

Until then, goodnight, and good luck.
