Molding Router Bits

You’re staring at a plain pine board, dreaming of the ornate Victorian trim in your neighbor’s century-old Craftsman. But hiring a carpenter costs more than your car payment, and your router’s dusty from last year’s shelving project. Enter molding router bits—the DIY savior that transforms $20lumberinto$200/ft architectural details. Whether you’re restoring historic trim, crafting custom cabinetry, or faking “built-in” bookcases for the ’Gram, here’s how to wield these profile wizards like a Gilded Age woodworker on a Home Depot budget.

Why Molding Bits Make Crown Molding Look Easy (Spoiler: They Do)

Molding router bits are the Swiss Army knives of decorative woodworking:

• Cost Slayer: Replicate $30/ft trim for pennies using basic pine or poplar.
• Time Machine: Create Georgian, Art Deco, or Mid-Century Modern profiles in minutes.
• Space Saver: Replace bulky shaper machines with a router and one good bit.
• Customizer’s Dream: Layer profiles like a pro (ogee + bead = instant Edwardian).

True Story: A Brooklyn DIYer used a $50 Roman ogee bit to clone her brownstone’s original 1920s crown molding—winning both a historic preservation award and 50k TikTok followers.
