The video “The Truth About MDF Will Make You Think Twice!” is by Stumpy Nubs (James Hamilton). In this insightful discussion, he tackles the often contentious topic of Medium Density Fiberboard (MDF) and its place in woodworking, arguing that there are valid reasons to consider this material even for fine furniture making.
James begins by recalling a previous video where he shared tips on using MDF, which sparked a wave of criticism from traditionalists who believe that only high-end woods, like rosewood, deserve a place in craftsmanship. While he appreciates the beauty of natural wood, he encourages viewers to set aside their biases against manufactured materials and recognize the unique advantages of MDF.
So, what exactly is MDF? James clarifies that MDF stands for Medium Density Fiberboard, a product made from wood fibers mixed with resin and pressed into sheets. Contrary to popular belief, MDF isn’t a cheap alternative; it often costs as much as decent plywood. Understanding the purpose of MDF helps reframe its value in woodworking.
James explains the inherent qualities of solid wood, which can swell, contract, and warp due to changes in moisture content. This natural movement requires woodworkers to use specific techniques to ensure durability in their projects. MDF, on the other hand, boasts a lack of grain, which means it doesn’t twist or warp like solid wood. Once sealed, MDF’s stability is one of its most appealing features, making it a reliable choice for certain applications.
For example, MDF is often used as a core substrate in veneered panels, as the movement of solid wood can damage the delicate veneer. Additionally, MDF can be machined and shaped in ways that plywood cannot, allowing for clean profiles without exposing unsightly layers. This capability is why MDF is frequently found in built-ins, even in high-end homes. Its smooth surface is ideal for painting, making it a popular choice for modern cabinet doors.
However, James acknowledges the criticisms that come with using MDF, particularly regarding its susceptibility to water. He humorously counters the fear that cabinets made with MDF will quickly deteriorate, suggesting that if a cabinet is absorbing that much water, there are more significant issues at play. He emphasizes that, when used properly, MDF can be a durable component in quality construction.
That said, he doesn’t shy away from discussing the drawbacks. Water is indeed MDF’s greatest enemy, and while it’s suitable for kitchen cabinets, it’s best avoided in areas with high moisture, like under a sink or near a dishwasher. Additionally, MDF can sag if unsupported, which means shelves longer than 18 inches require reinforcement.
Joining MDF can also be tricky; glue alone often isn’t strong enough. James recommends using mechanical joints, such as dados or grooves, combined with glue and screws for the best results. He cautions against moving MDF furniture frequently, as it’s best suited for built-ins that will remain stationary.
Dust is another concern; MDF creates a fine powder when cut, necessitating the use of a proper respirator. James stresses the importance of safety when working with this material, highlighting the need for proper dust management.
He also shares a tip for achieving a consistent appearance on MDF edges, suggesting the use of drywall joint compound or Bondo to treat fiber edges after cutting profiles. This attention to detail can elevate the final product, ensuring it meets aesthetic standards.
To draw a parallel, James compares MDF to plywood, likening it to how pocket screws are viewed in the woodworking community. He defends the use of pocket screws, pointing out that they have been used in quality furniture for centuries. Similarly, he believes that a veneered MDF panel, when used correctly, can outlast generations.
Ultimately, James encourages woodworkers to understand and embrace MDF’s proper use rather than dismissing it outright. He acknowledges that while there are alternative materials available, many craftsmen keep MDF in their shops because they recognize its value.
To wrap up, James introduces the M-Power SBS Diamond Sharpening System, which he describes as a handy tool for keeping edges sharp. This system is designed to provide everything needed for quick sharpening in one compact place, making it an excellent addition for any woodworker.
In conclusion, James makes a compelling case for not overlooking MDF in woodworking projects, urging craftsmen to appreciate its unique benefits while also being mindful of its limitations. With the right knowledge, MDF can be a valuable ally in the workshop.
