What You’ll Need

What You’ll Need

-Bench saw
-Aluminium sheet
-Sandpaper (220, 320, and 400 grits)
-Circular saw
-Tape measure
-Ruler or a straight edge
-Circular saw blade with a thickness of at least 3/8″ 
-Paint or a sealant
1. Start by measuring the width and length of the aluminum sheet you will be cutting. Cut the aluminum sheet to the desired dimensions using your bench saw. Be sure to double-check the measurements before cutting!
2. Once the aluminum is cut, sand it down using 220, 320, and 400 grit sandpaper. This will remove any rough edges and prepare it for the next step.
3. Next, use a circular saw to cut a rabbet into one end of each aluminum piece. The rabbet should be about 1/4″ wide x 1/2″ deep x 1 inch long. Make sure to keep the angle of the cuts even so that your pieces fit together perfectly when finished. Use a jigsaw to finish off this step if necessary. (See photo below)
4. Assemble each aluminum piece into a rabbet by sliding it into the other end of the last rabbit hole. Use either blue painter’s tape or silicone sealant to hold everything in place while it dries (See photo below). Be sure to apply pressure on all

How to Make Straight Cuts

If you’re looking to make straight cuts through aluminum sheets, there are a few things you’ll need:

A sharp knife.

A straight edge.

Aluminum foil.

An aluminum sheet.
Take your sharp knife and place it against the straight edge. Ensure the blade is perpendicular to the surface of the aluminum foil. Then, use your fingers to guide the blade along the straight edge line and keep your fingers tight against the aluminum while cutting. Once you’ve made your cut, peel the aluminum foil back and release the fabric from beneath it.

Tips for Making the Best Straight Cut

There are a few tips to follow when cutting through aluminum sheets.

1. Work with a piece of scrap aluminum the same size as the cutting material. This will help you get a consistent cut every time.

2. Make sure your blade is sharp and in good condition. A dull blade will not cut through the metal evenly, which can cause wrinkles or other irregularities in the final product.

3. Try to hold the aluminum sheet firmly against the blade while guiding it with the other hand. This will help reduce wobble and ensure a straight cut.

4. Take care not to touch the heated metal with your hands — it can be very dangerous! Instead, use a tool such as an angle grinder or a sacrificial anvil to remove any unwanted material before finishing off with a sharp knife or saw.

How to make straight cuts through aluminum sheets

Making straight cuts through aluminum sheets can be difficult, but it can be done with a sharp blade and a steady hand. Start by positioning the blade, so the cutting edge faces down towards the aluminum sheet. Then use your fingers to guide the blade as you make your initial cut. Once you have made a small initial cut, slowly move the blade toward the edge of the sheet, making sure to keep your fingers pressed against the aluminum. Repeat this process until you have made all of your cuts.

Tips on making straight cuts through aluminum sheets

When making straight cuts through aluminum sheets, it is important to keep the following tips in mind:

1. Make sure your saw blade is sharp. Dull blades will cause inaccurate cuts and may even tear the aluminum.

2. Use a steady hand and a comfortable grip when using the saw. If you are having trouble keeping your grip, use a clamped piece of wood to help stabilize the cutting surface.

3. Keep your arms and body as still as possible while cutting; any movement could cause the aluminum to tear or deform.

4. Try to cut only one sheet at a time so that the aluminum doesn’t have to support its weight while being cut and can stay flat against the workbench for easier cutting.


If you’re looking to make straight cuts through aluminum sheets, it’s important to use a straight edge and a sharp blade. To ensure the most accurate cuts, start by marking the edges of your sheet with a pencil or pen. Use the straight edge to make the initial cuts, then use the knife to finish off the cuts. Be sure to keep your hands steady and use light pressure when cutting; too much force can cause damage to your blade and your sheet.
