How to cut a rectangle out of a STEEL ruler?


You can use a scroll saw to cut it out. A scroll saw is similar to a jigsaw because it has a short, removable blade. These kind of saws are designed for very smooth and fine cuts that other saws aren't capable of.

Drill a small hole in the center of where the hole will be that is big enough to receive a scroll saw blade with a little bit of extra space. Carefully cut out the section, and cut slightly inside of the line, giving enough of a margin for finishing. Use a small to medium sized metal file to smooth out the hole, and bring it to the final dimension.

Rotary tools would not do a great job on this because the diameter of the cutoff wheels are probably larger than the hole you want to...

re: folding - will not work because you could easily end up with more than two parts cutting folded rectangle.

I would try brute-force approach. If the hole is co-oriented to large rectangle, you can cut along one of the edges and have only three cases to check: 1 try to cut above the hole - if it's not possible to end with same area halves, try to 2 cut through the hole - if it's still not possible, 3 cut below the hole will certainly do it. the code for 1 and 3 would be very similar, btw. all 3 cases are simple linear equations for the height of cut. For example, 1:

+----W---+ d | +--------+ | | | +-w-+ | H h | | | +---+ | | | | | +--------+

We have d * W = (H - d) * W - h * w

If d from this equation is not above the hole, go to case 2, and so...

For the lazy:

I was able to find a little bit of time over the weekend to get some more work done on the arcade cabinet. I finished making the last cuts on the bezel panel (cutting out the rectangle for the monitor). This proved to be a little more difficult than it sounds because I had no way of getting into the corners to make a perfectly square cut. I ended up eyeballing it and sanding - it came out OK but it will eventually be covered by the black posterboard bezel I'll be making to hide the monitor casing.

The first thing I did (after laying out the rectangle using a t-square and pencil) was to drill pilot holes in the corners. I picked the largest bit I had and drilled 4 holes about 1/8" inside of the lines. Next, using the holes I just cut as starting points, I used my jigsaw to connect the holes - again staying about 1/8" inside of the lines. You can see the pilot holes and the crooked lines I made connecting them in the picture below.

At this...

Due to certain circumstances it may be necessary from a sheet of rectangular form to make a square, for example, during the manufacture of many articles made from paper origami art. But not always at hand is a pencil and a ruler. However, there are ways through which you can get a box with nothing but ingenuity.

You will need:

- rectangle; - Line; - Pencil; - Scissors.

Instruction of how to make the rectangle a square

Step 1:

Rectangle - a geometric figure that has all four corners are straight, and a pair of sides parallel to each other. Opposing sides of the rectangle length identical to each other, and between the pairs of - different. The square shape is different from the previous one only in that it has four sides equal.

Step 2:

To make a square out of a rectangle, you can use a ruler and a pencil. For example, rectangle sides are 30 cm (length) and 20 cm (width). Then the square will have a side with a lower value, that is...

Steel rule die cutting is a common process used to cut a range of sheet materials, including paper, cardboard, rubber and plastic. Most standard cardboard boxes and packages are made using this relatively straightforward technique. In addition to cutting out shapes, it can be used to create creases, perforations and slits.

The die is constructed out of a flat base or substrate that is usually made out of high-grade and high-density plywood; the plywood is usually composed of hardwoods, such as maple, and is free from voids or other imperfections. Some special dies may require aluminum or steel substrates. The die-maker uses a special bandsaw or laser cutter to cut precisely positioned slits into the substrate. The steel rule itself is essentially an elongated razor blade made out of hardened steel. The die-maker cuts and bends the steel rule and positions it into the slits in the substrate.

The final step in creating the die involves the addition of ejection rubber....

For this page about the technique of bevel with 45°, I chose a simple, low-size example : the frame has as measurements 4"x5.2" and the margins must have 1.2".

First, I cut a rectangle 4"x5.2" in a foamboard sheet. Then I draw the opening (for well seeing this window on the photographs, I traced it with a black felt!).

(For the purists… one normally traces the opening on the back of the paperboard and have to works on the back… by reversing the direction of bevel… but it is here only about initiation…)

cutting the bevel

Bevel with 45° will be cut out with MAPED* ruler or a LOGAN matcutter: this one is composed of a ruler provided with a slide and a cutting tool which can coast in this slide. Of course, this cutting tool is automatically sloped with 45° angle.

Position the ruler so that you can see line of cut to a half-millimetre of the small window in the cutting tool (see photo). Slide to test the cutting tool without supporting...

Two questions I get asked all the time: "How do you cut your shapes so perfect?" and "Can I die-cut felt?!" Yes, I say while nodding my head enthusiastically! You can die cut felt -it creates perfect edges every time and makes Benzie's felt even more versatile and production friendly.

It is important to first note that there are two categories of machines: electronic and manual. Manual machines have been the most fool-proof option for our felt crafting uses and we will talk about them today.

There a several different brands of manual machines and dies available and most are are interchangeable using a combination of platforms and shims. We really love Sizzix's brand of machines and dies. The machines feel substantial and have held up to thousands and thousands of cuts (we cut A LOT of felt here!). We love them so much we offer our favorite machines and dies right in our shop!

There are two main categories of dies: wafer thin dies and...

You've Drawn your Inch! Here's what your completed Inch should look like- see Pictures 1 and 4. Now lets show you a couple of patterns and give you some tips and tricks!

Trick 1

Take a minute and look at the fractions. Do you see any patterns? There are two that stand out that can come in handy to check your work to make sure you drew your inch correctly...

1. Look at picture one again. What do you notice about ALL of the numerators?! THEY ARE ALL ODD. If you have an even number as a numerator, it needs to be reduced or you haven't got it in the right spot!

2. Look at the last fraction in each set as shown in Picture 2. Notice that in each fraction, the numerator is ONE LESS than the denominator!

Trick 2

You can use your completed inch as a calculator for reducing fractions. If you were to write ALL of the fractions down every time you did a set, your Inch would look like Picture 3. Each mark on the ruler that ends up with multiple...

There are two easy ways to cut a square from a rectangular sheet of paper.

Method 1:

Take a sheet of rectangular paper and fold it as shown. Use the edge as a guide to cut off the lower rectangle. Unfold the triangle and you will get a square with a diagonal crease in it. You can save the excess paper for another project.

Square from a Rectangle Method 2:

If you need a square sheet without the diagonal creases, try the next method.Take two sheet paper of the same size. Rotate one of them and overlay the two sheets perpendicular to one another. Use the edge of the top sheet as a guide to cut off the protruding section from the lower sheet. Remove the top sheet and you will get a square with no creases. You can use this square or the excess rectangle as a template to cut the other rectangular sheet into a square.

So this is how I go about making a leather cover for a notebook, complete with a pen holder. All going well after reading through this you should be able to make one of these.

First a disclaimer. I am new to leatherwork and have only read a book and some of the tutorials on British Blades so my way may well be the wrong way. So far it works but you have been warned

So first step is to catch yourself a cow, alternatively you can but some veg tanned hide. I get mine from . For the main cover and the fastening piece I use Culatta (grade 2) dyed through leather in mid Brown.

So lets begin. The first step is to cut out the cover piece. This is simply a rectangle. The size for yours will depend on your notebook. The notebook I use is an A6 Black & Red book. The book is 148mm high and opened out flat it is 225mm. The leather cover is cut to 165mm x 250mm. This is the size I have come up with after a few different versions. Any smaller and I have had...

A sheet metal toolbox can be a very handy item. It's sturdy, lightweight and will not rust. You can use it to store anything from your power tools to the kids' toys. However, sheet metal boxes can be very expensive. If you have some welding tools at home and some time on your hands, you can easily make your own box and save a lot of money.

Draw the dimensions of the sheet metal box on your sheet metal using a ruler and permanent marker. The size will vary depending on the intended purpose of the box. Typically you will want six panels in total, with two of them longer, to create a rectangular box.

Place your steel sheet on top of two sawhorses. Cut along each line with your cutting torch then smooth the edges with an electric grinder. Now you should have six separate pieces.

Put two pieces together at a time using a square measure to ensure they are perpendicular. Using a clamp to hold them in place, weld them together on both sides of the edge. Repeat for each...
