What are downrigger weights made of? There are several different sizes, shapes and colors of downrigger weights. Most weights are made of either lead or cast iron. The different shapes of the downrigger weights include round balls (cannon balls), round … Continue reading →

How do I measure it? To measure linear footage, start by measuring the length in inches. Then divide the total inches by 12. The length is the linear footage, so no fancy linear foot calculator is required. How is railing … Continue reading →

Standard Heights Additionally, standard balcony railing heights are typically 42 inches above the balcony deck, meaning the railing must extend that high and be capped by a horizontal rail for easy gripping. How tall should balcony railing be? The International … Continue reading →

The thickness gauge measures eddy current strength and the respective magnetic field produced and then calculates the thickness of the nonconductive coating. This test is often employed to measure the thickness of anodized aluminum and can also be used to … Continue reading →

The key difference between galvanized and hot dip galvanized is that most galvanized materials have a smooth and sharp finishing, whereas hot sip galvanized structures have a rough finishing. Galvanization is a process of preventing metal surfaces from corrosion. Which … Continue reading →

Two measurements must be taken: one with the coating in place and the other without. The difference between the two readings, the height variation, is taken to be the coating thickness. On rough surfaces, micrometers measure coating thickness above the … Continue reading →

The density of the zinc is 7.14. Therefore, a thickness of 1 micron of zinc is equivalent to 7.14 g/m2. Example: zinc coating thickness measured on one side of the CGI sheet is 20 µm. Then, the zinc coating mass … Continue reading →

Laboratory Testing A hot-dip galvanized coating may show a high zinc content near the outside of the coating with an increased iron content near the metal substrate. A zinc metallized or mechanically plated coating will contain a high zinc content … Continue reading →

Typical galvanized coatings range from 3-8 mils (75-200 mi- crons) thick. When designing and detailing tapped holes, the increased thickness is important. Best practice suggests that the hole be tapped after galvanizing, removing the coating on the interior mating surface. … Continue reading →

For an electric locomotive or a diesel-electric locomotive, starting tractive effort can be calculated from the amount of weight on the driving wheels (which may be less than the total locomotive weight in some cases), combined stall torque of the … Continue reading →

How do you measure post size? Step 1 – Measure the circumference of the post (distance around the post). Step 2 – Take that measurement and divide it by pi (3.14) to determine the post diameter. How are poles measured? … Continue reading →

Local Regulations Regarding Fence Height Fence regulations are typically governed by local law or a homeowners’ association. In many municipalities, six feet is the maximum height for a backyard fence, while a 4-foot fence may be used in front of … Continue reading →

Commonly, plastic canoes and kayaks are made from polyethylene or polypropylene. These low surface energy plastics are hard to bond to, making repairs difficult because the plastic surface inhibits the ability to spread an epoxy adhesive and wet out the … Continue reading →

If your dog is bothered by the surface, have him ride behind you — it’s easier to paddle that way anyway. Consider your dog’s weight and the amount of maneuverability you want to have when picking a board — larger … Continue reading →
