DIY Deep-Reach Clamp: Extend the Reach of a C-Clamp
Sometimes a woodworking project requires clamping pressure in a spot that's beyond the reach of an ordinary clamp. Deep-reach clamps can solve the problem, but they can be expensive for a tool you may only use occasionally.
Instead, you can extend the reach of a standard C-clamp with a pair of simple hardwood jaws. This shop-made accessory provides extra reach for tricky glue-ups and can be removed when you're finished.
Make Hardwood Extensions for Your C-Clamp
Start by cutting two hardwood strips long enough to reach the area where you need clamping pressure.
Drill a hole near one end of each strip and cut a notch to fit around the C-clamp body. The notch helps position the extensions while allowing them to pivot.
For a clamp body suitable for modification, drill mounting holes at locations that provide the desired reach. Keep in mind that longer extensions will flex more under pressure, so avoid excessive length or clamping force. Drilling a clamp frame can weaken it, so use a dedicated clamp only after evaluating the modification.
Add Clamping Pads & Attach the Jaws
Glue small hardwood pads to the ends of the extensions to provide a better contact surface against the workpiece.
Position the extended jaws around the clamp body and secure them with a nail or suitable pin through the mounting holes.
The hardwood arms transfer clamping pressure farther into the workpiece than the original C-clamp jaws can reach.
A Simple Solution for Hard-to-Reach Glue-Ups
With the extensions installed, you can apply moderate pressure to areas that would otherwise require a specialty deep-throat clamp.
Because the wooden jaws can flex, this setup is best for light-duty clamping rather than heavy-pressure applications.
When you're finished, remove the extended jaws and use the C-clamp for ordinary clamping tasks, provided the modified clamp remains structurally sound.
It's a simple, inexpensive woodworking trick that can help you get more use from the clamps already in your shop.
