Cutting 2020 Aluminum Extrusion

Aluminum extrusion can used for building cages/frames for electroincs projects.  There are any number of ways to cut it (aluminum is a very soft metal), but for my money, a jigsaw with a metal cutting blade is the easiest.  The blades are inexpensive, easier to change out then a blade on a table or miter saw, and work just as well.  The material I use is:

• 20mm T-Slot Aluminum Extrusion
• 24 TPI Jig Saw Blade

Keeping square cuts can be a challenge, but jigs can be used to make the job easier.

Once the material is cut to length, it can be assembled with corner connectors or brackets.  The center of 2020 aluminum extrusion can be tapped to accept a 6mm screw using the materials below:

• 6MM-1.00 High Carbon Steel Metric Plug Tap
• #9 drill bit (0.196)
• M6 x 25mm Phillips Flat Head Machine Screws

Cutting 12 sections of aluminum extrusion will allow you to assemble a cube suitable for a 3D Printer...
