Getting Crafty With Wire Mesh To Create Halloween Headstones

Posted by on Jul 27, 2016 in Uncategorized |

Halloween is the favorite holiday for many. Some people go all out decorating their properties to create spooky scenes that represent the true horror of the holiday. If you are looking for ways to decorate your property for the holiday that won’t break the bank, it’s time to consider all of the things that you can make with wire mesh, such as from Midwestern Industries Inc, and paper mache. To create outdoor-safe paper mache decorations, you will need a few supplies. Wire mesh Tin ships Zip ties Permanent marker Work gloves White glue – Elmer’s glue or off-brand variants Newspaper Spar urethane sealant Scissors Primer and paint Cardboard Box cutter Now that you know what you need, it’s time to think about what you’re going to create. You can keep it simple and make things like giant jack-o-lanterns and headstones or you can get really creative and involved and create zombies, ghosts and ghouls. The instructions below are for a basic headstone. You can use them as a guide to get more creative with intricate creations like the ghosts, vampires and zombies that you want to make. Step 1: Make a Stencil Draw the shape of the headstone that you want to create on a sheet of cardboard. Carefully cut it out with the box cutter. You can create different shapes and sizes, but you want a stencil to work with so that you get both sides of the headstone equal in size. You will also need a stencil for one piece of mesh to connect the front and back of the headstone. It needs to extend from one side to the other leaving the bottom open. Step 2: Trace and Cut Now, lay the stencil on the wire mesh and trace around it with the permanent marker. Put on the gloves and use the tin snips to cut the mesh leaving each side smooth – no pointy parts of mesh hanging out.   Step 3: Tie it Together Use the zip ties to tie everything all together. Use the scissors to cut off the excess plastic from the zip ties so that it doesn’t poke through the paper machete as you work to complete it. Step 4: Cover with Paper Mache Use strips of newspaper dipped in the white glue to begin covering the wire frame. Using the glue instead of the flour and water mixture will make the headstone more weather resistant. Using flour and water will cause it to fall apart and become crusty and gross while it is out in the rain and dew. Continue working to cover the headstone frame entirely and then let it dry for a day or two. Step 5: Get Painting...

How Couplers Are Engineered To Resist Wear And Tear

Posted by on Jul 6, 2016 in Uncategorized |

Couplings are made to connect rotating shafts in a mechanical device. They are also designed to absorb shock. Because of the role of a coupling, they are often placed under strain and will need to be engineered to be resistant to wear and tear that naturally results from their role. No matter how the system is designed, there is a transfer of power between shafts. Therefore, this transfer of power must be accounted for. Flexible Vs. Rigid Couplings The two types of couplings are rigid and flexible couplings. Rigid couplings do not allow for misalignment, while flexible couplings allow for a slight amount of misalignment. The type you choose affects how well the coupling will stand up to wear-and-tear and how long the coupling will last. Replaceable Gear Couplings Gear couplings are designed to be easy-to-replace after they have worn out. This is essential because this type of coupling does not allow for misalignment and will wear out more quickly. Flexible Grid Couplings One type of flexible coupling is the grid coupling. The grid holds together two hubs and absorbs force. Contact between the grid and the groove increases as the amount of force increases, allowing the coupling to perform outstandingly. Fluid Couplings Fluid couplings often have the least wear because there is very little contact between the moving parts of the coupling thanks to the fluid that separates it. Any contact that does occur is cushioned by the fluid. However, the sealing and bearing elements do experience some wear. However, one of the concerns of fluid couplings is that the coupling leaks. Many of these systems will continue to function properly after they have begun leaking, but as the hydraulic fluids deplete, the coupling will cease to function properly and new fluids will need to be added. Leaks also increase the risk that the hydraulic fluid becomes contaminated. Elastomer Couplings When couplings are used in high temperature environments, one concern is backlash. The solution is to use a flexible elastomer coupling that can allow for a few degrees of misalignment. That way, the system can tolerate some degree of backlash. Motion Control If the goal is to incorporate motion control into the couplings, this needs to be conceptualized early in the mechanical engineering process. Otherwise, the motion-control couplings will not meet the complex requirements of your machine. But with careful planning, you will engineer a machine that will stand up to wear and tear much better.
