DIMIDE 1/4 SERIES CLAMP DIMIDE 1/4 SERIES CLAMP | COMING SOON TO KICKSTARTER

The DIMIDE Camp Is Fast... Manual or Power Driven

DIMIDE Clamp Speed

The DIMIDE Clamp is fast. Clamp down 10X faster with a secure grip thanks to impact compatibility. If you don't have an impact, don't worry, the DIMIDE Clamp still tightens 2X faster compared to other clamps thanks to the turnbuckle screw.

10X Faster Power Tool Tightening

Power tools are fast, easy, and most importantly effective. Our goal with the DIMIDE Clamp was simple, to make it fast, easy, and effective. There was only one sure way to achieve this, bring all the benefits of power tools to clamps. We started by making the impact wrench compatible DIMIDE HD Series Clamp.

Impact compatibility delivers 10X faster tightening while also delivering a secure grip. With a 1/2" Impact Wrench, the DIMIDE HD Series Clamp delivers over 5,000 lbs of clamp force in just a few seconds. With a 1/4" Impact Driver, the DIMIDE 1/4 Series Clamp will deliver up to 2,000 lbs of clamp force in just a few seconds.

2X Faster Hand Tightening

The DIMIDE Clamp not only tightens quickly with a power tool, it also does by hand. Thanks to the turnbuckle screw design, the DIMIDE Clamp hand tightens at least 2X faster than other clamps.

The turnbuckle screw and the DIMIDE Clamp's configuration allows for the DIMIDE 1/4 Series Clamp to tighten at a rate of 1-Inch per 6 turns and the DIMIDE HD Series Clamp to tighten at a rate of  1-Inch per 4.5 turns. This delivers at least 2X the speed of standard clamps and is still even faster than comparable clamps with ACME screws. A standard 1/2-Inch Diameter ACME screw tightens at a rate of 1-Inch per 10 turns.

Knurled Safety-Stop For Tight Spaces

The DIMIDE 1/4 Series Clamp will include a knurled safety-stop so that tight spaces don't slow down your setups. We've always found it annoying when trying to tighten a clamp where the T-handle doesn't get clearance. Thanks to having a removable T-handle this annoyance can finally end. You'll now be able to simply remove the T-handle and finger tighten the clamp with the knurled stop.

Speed Without Reduced Performance

Making faster clamps isn't a new concept. Clamp manufacturers have been trying to reduce set-up time for a long time with faster clamps. While most of these methods have involved trading clamping force for speed, the DIMIDE Clamp combines speed and clamping force to delivered unmatched performance.

How Other Clamps Increase Speed

Incorporate a Slip Feature

A slip feature increases speed by allowing you to make large adjustments by slipping the clamp arm up or down a rail. This is common in f-clamps and other bar clamps. Using this method, the long rail experiences significant bending load. This bending load on the rail makes it much harder to deliver the strength needed fpr significant clamping force.

Slip features are also incorporated by adding threads to only half of a nut and then allowing the threads to disengage with a spring button. While this push button slip action, does make tightening clamps faster, it also leads to a massive reduction in clamp force capacity by cutting the screw thread strength in half.

The other downside of using a slip feature is that it still requires manual tightening of a screw.This tightening takes time, can lead to repetitive use wrist injuries, and limits your ability to get the clamping force you need.

Use a Locking Configuration

Locking Clamp

Locking configurations are another popular take on fast action clamps. First introduced with the Irwin Vise Grips, these clamps generate a locking mechanism using an over-center toggle action. As your grip down on a locking clamp, the toggle linkage begins to straighten. As the linkage straightens, the leverage and clamping force increases which stores elastic energy in the clamp. Eventually the linkage completely straightens which is where the maximum amount of force or energy is stored in the clamp. However, because the linkage is attached by only a pin it is unstable in a straight position and wants to buckle. At this point griping the clamp a little more forces the linkage to buckle downward releasing some energy but being stopped from releasing all of it's energy by other the screw stop and handle bumper. The remaining energy that is still stored in the linkage maintains the holding clamp force. The closer the linkage is to being straight, the greater the holding clamp force is.

There are a few downsides to this configuration.

  1. The clamp is limited by grip force to apply clamp force.
  2. The clamp does not maintain a clamping force equal to its maximum or it's rated load.
  3. This requires adjusting the screw prior to clamping which can greatly slow down setup times

Use an ACME screw

ACME threads are becoming more and more popular especially in vises, but are also making their way to clamps. ACME screws are used for two reasons.

  • ACME threads provide greater thread strength
  • ACME threads speed up tightening with fewer threads per inch

Despite these advantages, ACME screws do have some disadvantages.

  • Reduced shaft diameter from large threads reduces screw shear strength which is the predominant failure mechanism of screws.
  • ACME threads require special more expensive manufacturing methods.
  • Larger screws require larger nuts which further increases costs.

While ACME screws do have fewer threads per inch compared to a standard screw, our use of a turnbuckle screw along with our clamp's configuration delivers 2x faster tightening than comparable ACME screws. The DIMIDE clamps also optimizes the trade off between shaft diameter and thread size to maximize screw strength.

Conclusion

The DIMIDE Clamp delivers speed without sacrificing clamp force or performance thanks to impact compatibility and the turnbuckle screw.

The DIMIDE 1/4 Series Clamp is coming soon to Kickstarter to make impact compatible clamps affordable.
