Pony Tools ¾-Inch Pipe Clamps #50
|Pony Pipe Clamps are bulky cast-iron bodies that are threaded for ordinary black pipe. Each clamp consists of a fixed head-stop with a crank and a moving tail-stop that slides along the pipe. There’s also a little metal coil that keeps the tail-stop from sliding off. Both head- and tail-stops are painted "Pony Orange" for visibility. The worker buys the pipe separately, allowing you to customize a pair with pipe up to twelve feet long. Since the clamp heads are easily removed and remounted, one set could find use on different lengths.
The tail-stop slides toward the head-stop easily, but grabs the pipe with a spring-loaded clutch when you try to move it in the opposite direction. This clutch releases easily so the stop can slide again. The head-stop clamping face is mounted on crank-driven screw with a range of about 3 inches. Both faces are enamel-coated cast iron, some 1¾" square. You can find plastic slip-on pads that will protect wood surfaces, though if there’s enough room wooden clamp blocks protect edges and spread the clamping surface. Both stops have a bottom projection that acts as a foot so there’s clearance under the pipe when the clamp is resting on a flat.
Using a Pony Pipe Clamp
Long clamps can be pretty heavy, requiring some muscle to sling around. Although a five-foot pipe’s a useful length is around 4½ feet, you can string two (or more) clamps together to cover larger spans. Black pipes are commercially available up to 20 feet long, but most woodworkers only need four or five feet.
Any experienced woodworkers will tell you that you can never have too many clamps. With an assortment of pipes and a few ¾-inch Pony Pipe Clamp sets, though, even part-time DIYer can get a start on “enough.”
