Center Finder Line Gauge Square Center Scribe Carpenter Woodworking Ruler 45 Degrees Angle Line Caliber Marking Ruler Wood Measuring Scribe Tool

I bought this as a replacement of a different brand that I bought from Amazon and it has worked perfectly. The ruler locks easily into place by the four locking screws. It's made from Aluminum and the machining is spot on.I would definitely buy this one again if I needed another one.

Very well built, dead on accuracy. One reviewer stated to tighten the lower screws first - he was correct, if you don't it will skew a little off. After putting it together, I checked with my reference squares and it was dead on to 90 degrees, which you need to accurately find center on any circular object.I bought a similar one from Temu and it never worked properly, always off center and Temu's was about the same price as this one and poorly constructed.One reviewer complained that it only had metric measurements - either he received bad one or he didn't look at the other side. This has centimeters on one side and Inches on the other.I will probably buy more for family members who do a lot of wood working and other household projects.

The DDWT Center Finder Line Gauge Square Center Scribe Carpenter Woodworking Ruler works well for finding center lines and marking precise measurements. The quality of the material is solid, and it provides accurate results for woodworking tasks. However, I found it a bit tricky to use at first because it didn’t come with clear instructions on how to properly utilize all of its features.Once I figured it out, it made my projects much easier, but a small guide or instructions would have been helpful for those new to this type of tool. Despite that, it’s a great addition to any woodworking toolkit, and I’m pleased with its performance overall.

I was a little uncertain with purchasing this when I saw the rationale for the few negative reviews. But, the problem is likely that they did not set up the device properly. When attaching the ruler and tightening the screws down, tighten the bottom set FIRST (the ones in my photo next to the Allen wrench) and then tighten the top ones. If you do the reverse the ruler will skew a little and your center will be off. Works perfectly and would buy again. The second image shows 10" and 12" cake pans.

I bought this to mark the center of some cans. Its sturdy and well made. I had tried a few other solutions, but none of them worked 100%. I needed to drill holes in the end of some cans to turn them into lamps. This worked great - nice and quick with no errors.

A quick way to find the center without having to do a lot of measurements.

As a machinist I’m used to paying nosebleed prices for my tools. My wife picked this out for my birthday after seeing something similar on my wishlist. Because of the price I expected very little. I was flabbergasted by the attention to detail! It measures to the 1/50th of an inch and finds center, radius and diameter within 1-2 thousandths of accuracy! I thought this might be clever in my wood shop where accuracy is in 1/16ths but I took it straight to my metal lathe and rely on astounding accuracy. If you are starting out in machining and don’t have $280 for a ‘Starr-Brow-Sharp-Lufk-kidoodle super pro tool? Buy this one and be amazed at a lifetime quality highly accurate tool that you will pass on to your kids!

Not very good at finding the center of 1.5” dowel rod. Ruler pops out, screw doesn’t hold very well. Not impressed.
