For holding miters together while gluing, reader fred recommended the Clam Clamp as an alternative to spring miter clamps. The Clam Clamp holds the work pieces together so securely that you can pick them up and carry them around while the glue is still wet.
Chestnut Tool designed the Clam Clamp specifically to make the assembly of door and window casings faster and simpler. With one half-turn of the handle the unique cam design secures the miter joint. But how does it stay in place, you ask? Little nickle-plated alloy pins perpendicular to the jaw bite into the wood to keep it in place. It does leave a few easily filled dimples in the edge of the wood, but so would spring clamps or nails.
Chestnut Tools machines the Clam Clamp from stainless steel and solid brass right here in the US. The rustproof and rugged construction ensures these clamps will be reliable for a long time.
Buying directly from Chestnut Tools, you’ll pay $75 for one clamp, $65 each for two Clamps, $60 each for four clamps, or $55 each for eight or more clamps. They don’t specify what the shipping and handling charges will be.
