J.C.'s love affair with the conservation of American vintage furniture began out of necessity. Searching for a desk that was both practical and interesting, J.C. uncovered a run down 1948 tanker desk at a flea market. After stripping off many layers of beige paint, J.C. was taken aback by the raw steel gleaming underneath. This moment inspired him to start refurbishing other vintage steel finds. After making every mistake possible on his own furniture, J.C. perfected what is now the Twenty Gauge Process and launched his company, Twenty Gauge a year later. The process includes evaluation, thorough removal of corrosives, replacement of worn parts, industrial strength sandblasting, layers of powder coating and more. Each time consuming step is what guarantees that every Twenty Gauge piece will not only look fantastic, but will withstand the test of time.

An ideal choice for backpackers, the Mountaineer carbon fiber monopods combinee the advantages of exceptionally low weight with strength and rigidity. They're 30% lighter than equivalent aluminum monopods, making the Mountaineer the choice for serious amateurs and busy professionals on the move. The 1588 is the largest diameter Gitzo monopod, intended to support the most difficult of handheld applications such as 600mm f/4 & 400mm f/2.8 telephoto lenses or even the occasional masochist with a penchant for handholding a large view camera

I have been considering getting rid of my tripod this year. Actually truth be told my trustworthy assistant (AKA my wife) is unwilling to carry it on long hiking trips So I have been considering a Monopod. But I have had concerns about the stability of a monopod. But today I just learned about this new Monopod from Manfrotto the 685B. Now this monopod is self locking when you open it up and can hold up to 18 pounds, more than my cheap lenses weigh. It is cool because it has monopod stretches up to 65 inches and collapses down to 28 inches and pretty lightweight, perfect for hiking. Plus the suction cups on the bottom of the foot seems like it will provide a lot of stability. If the price is right I just might make a change.

Shown above in use with bases and adjustable uprights (SOLD SEPARATELY), these telescoping, heavy-wall, high-strength, anodized aluminum drape supports can be used at any length from fully collapsed to maximum stop length. Units with a collapsed width of 5' or longer can extend approximately one foot past the maximum stop. Drapes and drape supports should always be mounted and removed while the uprights are vertical; never tip the structure up or down.

A few months ago a coworker held up the item pictured above and said, “This is called a cheeseborough.” I didn’t believe him, nor could I see any particular use for the tool. Later, I found out he wasn’t making up the term, and that all a cheeseborough does is clamp onto 1-1/4″ to 1-1/2″ pipe. And a few days ago I found out what makes this odd tool so cool.
Last week some guys were prepping for an outdoor event, and I got to see ‘em put up an aluminum truss structure, made of tubing around 1-1/4″ to 1-1/2″ in diameter. I found out that with a cheeseborough and some pipe, you can hold almost anything. I saw cheeseboroughs used to hold ceilings, large fabric headers, plasma screens, and just about anything else that could be clamped down with it.

Kee Klamp competitor. Might be cheaper.

Harbor Freight’s structural pipe fittings let you connect standard 1-1/4″ OD PVC or steel pipe, and they cost a fraction of that of name brands like KEE CLAMP. They’re also galvanized to resist rust. Attaching the structural pipe clamps involves tightening a single hex drive screw per connection. Of course, you still have to supply the pipe, but you can score 1-1/4″ PVC or steel pipe on the cheap at most big box stores.

Date: 2009-07-17 12:27 am (UTC)However side-handle batons have serious issues. Just because lots of cops carry them does not make them any good.
A strike with a stick is a natural motion that uses the strongest muscle groups in your arms. A tonfa or PR-24 strike requires unnatural motions with accessory muscles. The side-handle actually worsens the grip in some situations.
It seems as if one would be able to block effectively with a side-handle baton. The answer is yes and no -- and why block when you can parry, and why parry when you can both parry and strike?
