Game-changing sine opening for precision work

As a result of using this tool, I found that my precision work became much easier and more accurate. The design is incredibly solid and the build quality is top-notch. However, the price tag may be a bit steep for some users. Pros: Easy to use, accurate measurements, high-quality construction. Cons: Expensive.

Pros
  • Accurate and precise measurements can be achieved with the HHIP 3900 2605 Precision Sine Opening.
Cons
  • Requires additional tools to fully utilize its potential, which can increase the cost of use.

Check the distance between the centers.

I bought a 3 inch vise. In general everything is fine. A few things to mention, the most important being that this is not a 4 inch sine. When measured, mine is 4.005 between centers. The fixed jaw is about 0.0015 higher than the movable jaw, and finally the movable jaw has a slight taper. All other measured values were within the acceptable range. So not a bad device for the money. Just make sure you know what wheelbase is

Pros
  • Elegant design
Cons
  • Long delivery time

Not good.: Hand tool

The first one I bought had the base bent about 0.05" (1/16") all the way to one side and could be about 0.1" (1/8") be rocked back and forth. "). I thought "Maybe it was just bad" sent it back and ordered another one. The next one was a little higher quality, didn't wobble VERY much, still had about 0.02" of back and forth play, which didn't was not at all accurate to .0004" for tooling and dies. There were gaps in the ground cylinders on the ends, grinding sludge all over the vise (seriously…

Pros
  • Absolutely amazing!
Cons
  • Not bad, but...
