  3. Attach the Casters:

    • Position each caster over the marked spots and secure them using screws that come with the caster set.
    • Use a drill to drive the screws into the bottom of the bar (predrill holes to ensure that the wood doesn’t split), ensuring the casters are firmly attached.
    • Make sure all casters are properly aligned and that the locking mechanisms are functional.
  4. Test the Mobility:

    • Once all casters are attached, test the mobility of the event bar by moving it around.

Step 10: Setting Up and Collapsing the Folding Event Bar

Sub-step 1: Prepare the Components

  • Instructions:
    • Transport all components of the folding bar to the assembly site.

Sub-step 2: Open the Main Bar Component

  • Instructions:
    • Open up the main bar component which includes the bar sides attached to the front with piano hinges.
    • Swing out the bar sides to 90 degrees to form a U shape.
    • Lower all of the shelf support flaps.

Sub-step 3: Install the Shelves

  • Instructions:
    • Place the top storage shelf and the bottom storage shelf onto the corresponding shelf flaps.

Sub-step 4: Add the Bar Top

  • Instructions:
    • Position the bar top directly on top of the main bar component (the assembled front and sides).

  • Instructions:
    • Install the bar wings to interlock the bar top and the bar sides together, ensuring the structure is heavy-duty and secure for use.

Safety Note:

  • Caution:
    • Avoid placing too much weight on the bar wings. They are designed for lighter items such as utensils (spoons, forks, knives), cups, serving utensils (spatulas, ladles), and napkins, not for heavy loads.
    • Utilize the bar wings to extend the bar surface and keep the main bar area clear and organized.

Step 11: Finishing and Renting Out the Event Bar

Sub-step 1: Sanding the Bar

  • Materials Needed:
    • Fine-grit sandpaper (e.g., 220-grit)
    • Sanding block or electric sander
  • Instructions:
    • Gently sand the entire surface of the bar, including all wooden components.
    • Use light, even pressure to avoid removing too much material, especially on plywood which can be damaged if layers are stripped.
    • Focus on smoothing out rough edges and any splinters.
    • Ensure all surfaces are smooth to the touch, preparing them for either staining or painting.

Sub-step 2: Staining the Bar

  • Materials Needed:
    • Wood conditioner
    • Wood stain of your choice
    • Clear coat polyurethane
    • Brushes or rags for application
  • Instructions:
    1. Apply Wood Conditioner:
      • Cover all wooden surfaces with wood conditioner.
      • This step ensures an even absorption of stain, preventing blotches and enhancing wood grain.
    2. Stain Application:
      • After the conditioner has dried, apply the wood stain using a brush or rag.
      • Work in sections, maintaining a wet edge to avoid lap marks.
    3. Seal with Polyurethane:
      • Once the stain has fully dried, apply a clear coat of polyurethane to protect the surface.
      • This layer provides durability and resistance to water and other elements.

Sub-step 3: Painting the Bar

  • Materials Needed:
    • Primer (if necessary)
    • High-quality acrylic or enamel paint
    • Paintbrushes or rollers
  • Instructions:
    • If the wood is untreated, start with a coat of primer to ensure better paint adhesion.
    • Apply at least two coats of paint, letting each coat dry completely before applying the next.
    • Use high-quality paint for durability, especially if the bar will be used outdoors or subjected to frequent handling.

Sub-step 4: Renting Out the Bar

  • Suggestions:
    • Price the rental at $150-$200 per event, depending on your location and the type of events.
    • Market the bar as a versatile and elegant addition to weddings, parties, and corporate events.
    • Maintain the bar in top condition by inspecting and touching up the finish as necessary between rentals.
    • Use contracts specifying rental terms, liability, and damage policies to protect your investment.
