Picnic Table Plans for Round or Oval Designs

Picnic Table Plans for Round and Oval Designs: A Comprehensive Guide

This document provides detailed plans for constructing both round and oval picnic tables, catering to various skill levels and aesthetic preferences. The designs emphasize durability, stability, and ease of construction, while offering flexibility in material choices and overall dimensions.

I. Planning and Material Selection

A. Design Considerations

Before embarking on construction, careful planning is crucial. Consider the following factors:

• Table Dimensions: Determine the desired diameter (for round tables) or length and width (for oval tables). Consider the number of people the table should comfortably accommodate. A general guideline is to allow approximately 24 inches of seating space per person.
• Material Selection: Popular choices include pressure-treated lumber (for its durability and resistance to rot and insects), cedar (for its natural beauty and rot resistance), redwood (for its strength and longevity), and recycled plastic lumber (for its eco-friendliness and low maintenance). Select lumber with minimal knots and warping for optimal strength and aesthetics.
• Style and Features: Decide on the desired table style – simple and rustic or more elaborate. Consider adding features such as built-in umbrellas, benches with backs, or storage compartments.
• Site Preparation: Choose a level and stable location for the picnic table. Ensure adequate clearance around the table for comfortable access and movement.

B. Material Quantities

Accurate material estimation is vital to avoid unnecessary expenses and material waste. The quantity of lumber required depends heavily on the chosen design and dimensions. For precise calculations, it is recommended to create detailed drawings and utilize online lumber calculators that account for cuts, waste, and joinery. However, the following serves as a general estimate for a medium-sized round table (approximately 60-inch diameter):

• Tabletop: Approximately 12-15 linear feet of 2x6 lumber (or equivalent dimension for the desired thickness). This will require cutting multiple boards to create the circular top.
• Legs: 4-6 pieces of 4x4 lumber, approximately 30 inches long (adjust based on desired table height).
• Support Beams (for the tabletop): 6-8 pieces of 2x4 or 2x6 lumber, depending on the chosen support structure.
• Benches (if included): A significant amount of lumber will be required for the benches, depending on their length and design. Estimate based on individual bench length and width.
• Fasteners: Exterior-grade screws, bolts, and possibly metal brackets. Ensure the chosen fasteners are appropriate for the chosen lumber.

For oval tables, the lumber requirements will vary depending on the length and width. Larger tables naturally demand more material.

II. Construction of a Round Picnic Table

A. Creating the Circular Tabletop

The construction of the round tabletop requires careful measurement and cutting. Several methods can achieve this:

• Using a compass: Draw a circle on a large sheet of plywood using a long rope and a nail as a compass. Then use this template to guide cutting the lumber boards.
• Using a jig: Construct a simple jig with a circular router bit to precisely cut the lumber boards into the desired curve.
• Layering and shaping: Cut individual boards to a slightly larger radius and gradually shape and fit them together to form a circular tabletop.

Once the individual boards are cut, carefully join them together using wood glue and exterior-grade screws. Ensure the joints are flush and the tabletop is stable and level. A wood clamp system is vital for this stage of construction.

B. Attaching the Legs and Supports

The leg placement must ensure stability and equal weight distribution. For a round table, evenly spacing the legs is crucial. Attach the legs to the underside of the tabletop using robust screws and/or metal brackets. Consider adding support beams between the legs for additional stability, especially for larger tables. These beams should be securely attached to both the legs and the tabletop.

C. Finishing Touches

Sand all surfaces smoothly to remove any splinters or rough edges. Apply a weather-resistant sealant or stain to protect the wood from the elements. This process should be done thoroughly to prolong the table's lifespan. Allow ample drying time before placing the table in its intended location.

III. Construction of an Oval Picnic Table

A. Constructing the Oval Tabletop

Creating an oval tabletop presents a unique challenge compared to a round one. Options include:

• Using a flexible template: Create a template from flexible material, such as thin plywood or a long strip of flexible plastic, outlining the desired oval shape. Use this template to guide the cutting of the individual lumber boards.
• Layering and shaping (more complex): This method is more challenging and requires precise measurements and cutting skills. It involves meticulously fitting and shaping multiple boards to create a smooth oval surface.

Once the boards are cut, join them using wood glue and exterior-grade screws, paying close attention to creating a tight, smooth, and stable top.

B. Leg and Support Structure

Oval table leg placement requires careful consideration to ensure stability. Typically, legs are placed at the four corners, with additional supports added under the center of the longer axis. The supports are crucial for preventing sagging. Securely attach the legs and supports using robust fasteners.

C. Finishing the Oval Table

Similar to the round table, sand the surfaces thoroughly to remove any splinters or rough edges. Apply a weather-resistant sealant or stain to protect the wood. Allow ample drying time before placing the table in its designated location.

IV. Safety and Maintenance

Safety: Always wear appropriate safety gear, including safety glasses and gloves, during construction. Use caution when handling power tools. Ensure the finished table is stable and free of any sharp edges or splinters. Regularly inspect the table for loose screws or damaged components and address any issues promptly.

Maintenance: Regularly clean the table to remove debris and dirt. Reapply sealant or stain as needed to protect the wood from weathering. Store the table under cover during periods of inclement weather if possible. Proper maintenance will significantly prolong the life of your picnic table.

By following these comprehensive plans and taking necessary precautions, you can successfully build a durable and aesthetically pleasing round or oval picnic table that will provide years of enjoyment for you and your family.
