Questions & Answers
You can simply use two squares back-to-back if you have a good flat surface (a stone countertop could work if you do not have a surface plate). If the blades are not flat (or anywhere along the middle, if your blades are not flush against each other), you should see any light between the top and bottom of your blades. Depending on how flat all surfaces are, this can be a very sensitive test. If you conduct such a comparison, all you are showing is that two squares add 180, not necessarily that each of them is 90. However, you can prove that by comparing each square
Because I do not have access to a surface plate and height gage, it is impossible to provide an accuracy measurement. I would, however, estimate that I would be within 0.5 percent of my other equipment. This represents the beginning of the sequence "001"- This area is 7" square, so it is 002".
As a general rule, each square is the following size "* B . The size of this work is 4" x 25". 5 x 3 inches, 25 inches wide by 5 inches tall. A size of 25", a size of 4x2, and a width of 2 inches. Approximately 75" wide, 3" deep, and 2" wide. 0 is used for all three of the smaller squares. A 75" wide material can be used. One inch wide material is used for the large square. Thank you. I hope this was helpful.

It was obvious that three of the four pieces in the set were not Take a look at the photos.
I will be returning the item for a.
Although I worried about buying an off-shore set of squares at a low(er) cost, I couldn't afford a renowned high quality brand. I figured Grizzly, which is very well known in the US, would have rigorous product reviews and quality assessment. There was a mistake on my part. In the photograph, you can see that they are not even square with one another. A block is not square with this area. Edges aren't visible since you cannot see them. Several of the squares have rounded edges, as if they were pressed into place too hard or a shear was not sharp and beaded Was planning to use them for light gunsmithing and other miscellaneous tasks, as well as for tool setup or machine Still waiting for my return request to be responded to.
It is a fact that you will not be able to use these for your job if you are a machinist. To make sure the set is correct, I checked it against itself. One of them had burrs on its outer edge and the other had a banged up outer edge. Most of them were corroded, had scratches, and the oil was unevenly distributed, causing spots of crud to form on them. Although the packaging was secure and safe, it was difficult Make your budget go a little further (or a little further Better than these) and get a better set. I would say that these look and work like they have been severely used already by someone who hasn't taken care of them well.
The pros are
They are to be used on my desktop CNC mill, so they need to be precise (but not ultra precise The precise number). In your opinion, what is the most important? You're on square! It's hard to tell how well these meet the specification, but when nesting there are no discernible (Compare to the similarly priced Omex set, which had a 1/16" space out of square! *a) Cons The stainless steel appeared to be the better option because I don't want to maintain rust-prone Nevertheless, they were shipped in oily bags, so they were definitely not stainless steel. On one of the largest squares is a rather large corrosion patch. Since it can be removed and is not on a critical surface, it is not a deal breaker. (In actuality, rust took hold inside the oily bag so it was there already. What a lazy way to spend time! *) No case, but also no big deal. In cases, there is a lot of space required.
A bit surprised by how small they were, but that's my own fault for not reading the description all the way. My garage workshop requires these to square up fences and miter saw blades and they were handy for making jewelry boxes for my wife and daughter. Even the smaller ones are effective for squaring up fences and miter saw blades and are easily carried around. If you're into higher end woodworking, furniture making, or something that requires high precision accuracy, then Starett might be the better choice, but for weekend hobbyists these are pretty decent.
Using this set is perfectly OK for those who do woodworking and or need to set up woodworking machines like table saws, miter saws, or any other woodworking tool that requires precision. These squares are packaged in a bag with oil in it to prevent rust. And as stated in the previous reviews, they are NOT stainless, but rather a sturdy steel. You might be less inclined to take care of them, but you can still store them on a magnet.
It's not even for building a rocket ship. Upon arrival, the items were in good condition. This item is not stainless steel, as stated by another reviewer. In any case, it doesn't bother me. It is highly unlikely that they will rust if they are coated lightly with paste wax. I, in fact, prefer them to not be stainless, so that I can use magnets to hold marking jigs I have made at home. '
I checked them for squareness and they are all fine. They are not supposed to be perfect. I'm not saying they are, but they aren't supposed Here is what I need if I need a square. Once I discover that it has been tested for 0005 TIR over the entire length of the blade, I will shop for a square with it, and I will expect to pay far more for 1 square than the cost of these four. Despite some reviewers' assertions to the contrary, they are real toys, and they are square as well. The woodworking supplies I found here will be great for you if you are a woodworker. You can run as much as you want The amount of wood movements that will occur is much smaller than what is actually out there. A square with a certification of accuracy would be a good option if you really want one that is super precise.
A horizontal bent edge (or an edge that is not straight) is visible on the biggest square, but a vertical straight edge remains.
Should this make any sense, it's the same as having a ruler that is straight on the upper edges but is bent on the lower ones when laying flat on the desk. Technically, it serves its purpose because the vertical part of it is straight and the angles are square, but its bent edge has a bad aesthetic.
