Spotdrillangle

Back in 1903 the proud owner of a #30 would match his angle, mark his material and cut to the line with a sharp hand saw. That will certainly work with an Engle Angle, but we're well aware that the vast majority of folks today are using power miter saws instead of hand saws. If you have a miter saw with a laser, mark your material then use the laser to line up to your mark…almost like they did it in 1903.

Nickel-titanium alloys feature shape retention of shape memory properties. By forming a shape from this alloy at a higher temperature and them deforming it from that formed shape at a lower temperature, the alloy will remember the initial shape and reform to that shape once heated to this so-called transition temperature. By controlling the composition of the alloy, the transition temperature can be altered. These alloys have a super-elastic property that can be exploited to provide, among other uses, a shock absorber against earthquake damage to help protect stone buildings.

Q: What are the dimensions of the Engle Angle?A: The handle is 7 ¼” in length and the arms are 6” in length measuring from the hole. The handle is 7/8” in width and the arms are 1/16”.

These alloys of nickel add chromium and molybdenum to add creep rupture strength to the alloy. Alloy 617 is an example, sold under the trade names Inconel 617® and Nicrofer® 617, which has a composition of 20-24% chromium, 10-15% cobalt, and 8-10% molybdenum with a minimum nickel content of 44.5%. Applications for these alloys include industrial furnace components, gas turbines, catalyst grid supports to produce nitric acid, and fossil fuel production facilities.

Woodpeckers Engle Angles introduce modern materials and manufacturing techniques to a classic trim carpentry tool. In 1903 one of Stanley Tool Works most prolific engineers patented the #30 Angle Divider. By fitting the connected legs into an existing corner, the tool bisects the angle automatically. This is particularly important when mitering trim for existing structures. Corners that should be 90° usually aren't. If the corner is 88° instead of 90°, the Engle Angle bisects the angle and you'll get 44° instead of 45°. Similarly, if you have to trim around walls with hexagon or octagon corners you can get perfect bisections of those angles just as easily, whether the existing structure is "spot on" or "kinda close".

Nickel-iron alloys function in applications where the desired property is a low rate of thermal expansion. Invar 36®, also sold with trade names of Nilo 6® or Pernifer 6®, exhibits a coefficient of thermal expansion that is about 1/10 that of carbon steel. This high degree of dimensional stability renders nickel-iron alloys useful in applications such as precision measurement equipment or thermostat rods. Other nickel-iron alloys with even greater concentrations of nickel are used in applications where soft magnetic properties are important, such as transformers, inductors, or memory storage devices.

Nickel-chromium-iron alloys combine these elements to produce alloys that resist oxidation and high-temperature corrosion. Alloy 800, sold under the trade names Incoloy 800®, Ferrochronin® 800, Nickelvac® 800, and Nicrofer® 3220, is used in furnace components such as petrochemical furnace cracker tubes, and as a material for sheathing of electrical heating elements. These alloys generally are also valued for their optimum creep and rupture properties at high temperatures. The composition of these alloys is typically 30-35% Nickel, 19-23% Chromium and a minimum of 39.5% Iron. The high concentration of iron has led to the reclassification of these alloys as stainless steel.

Q: What degree of angle can the Engle Angle be adjusted to?A:  The Engle Angle adjusts between an inside angle of 30° and an outside angle of 85°

Nickel-copper alloys are very resistant to corrosion by salt water or seawater and thus find application in marine applications. As an example, Monel 400®, also sold under the trade names Nickelvac® 400 or Nicorros® 400, can find application in marine piping systems, pump shafts, and seawater valves. This alloy as a minimum concentration of 63% nickel and 28-34% copper.

But not all saws have a laser, so we boosted the thickness of the upper section of the handle and replaced the rivet found on the Stanley with a threaded knob. With one leg unlinked and folded out of the way, you have a longer, taller reference area next to your saw blade. No scales to read, no judgements about where degree fractions should land, just a solid reference to a perfectly bisected angle.

Nickel-molybdenum alloys offer high chemical resistance to strong acids and other reducers such as hydrochloric acid, hydrogen chloride, sulfuric acid, and phosphoric acid. The chemical makeup for an alloy of this type, such as Alloy B-2®, has a concentration of molybdenum of 29-30% and a nickel concentration of between 66-74%. Applications include pumps and valves, gaskets, pressure vessels, heat exchangers, and piping products.

Nickel-chromium alloys are prized for their high corrosion resistance, high-temperature strength, and high electrical resistance. For example, the alloy NiCr 70/30, also designated as Ni70Cr30, Nikrothal 70, Resistohm 70, and X30H70 has a melting point of 1380oC and an electrical resistivity of 1.18 μΩ-m.  Heating elements such as in toasters and other electrical resistance heaters make use of nickel-chromium alloys. When produced in wire form they are known as Nichrome® wire.

Similar to our other re-designs of early Stanley classics, Engle Angles honor the original design but go further with tightened up tolerances and modern materials. The body is machined from aircraft grade aluminum on CNC mills, then anodized in our familiar “Woodpeckers Red” finish. The marking legs and knobs are all stainless steel. Nylon washers protect the sliding joints. It's a tool that will look as good as it works for generations to come. While the Engle Angle 6" can bisect any inside angle from 30° to 180° and any outside angle from 180° to 85°, Engle Angle MINI can do the same for any inside angle from 30⁰ to 180⁰ and any outside angle from 180⁰ to 110⁰. A padded storage hanger is included to keep your Engle Angle right in plain sight and always ready to go to work.

With similar applications to nickel-molybdenum alloys, nickel-chromium-molybdenum alloys also provide high corrosion resistance especially with regard to reducing acids such as hydrochloric acid and sulfuric acid. One of the best known of these alloys is Alloy C-276, also sold under the trade names Hastelloy C276®, Nickelvac® HC-276, Inconel® 276, and Nicrofer® 5716. This alloy is used in pollution control stack liners, ducts, and scrubbers, as well as in chemical processing components such as heat exchangers, evaporators, or reaction vessels. The composition of this alloy is primarily nickel with 15-17% molybdenum, 14.5-16.5% chromium, 4-7% Iron, 3-4.5% tungsten, and smaller concentrations of other elements such as manganese.

Nickel will alloy easily with most metals such as copper, chromium, iron, and molybdenum. The addition of nickel to other metals alters the properties of the resulting alloy and can be used to produce desired characteristics such as improved corrosion or oxidation resistance, increased high-temperature performance, or lower coefficients of thermal expansion, for example.

Like all Woodpeckers products, Engle Angle is precisely machined and carefully inspected in our Strongsville, Ohio, facility just south of Cleveland.
