Metal Railing Fabrication and Installation
At 9:35 in
DIY Staircase Makeover
What happens here
To fabricate the metal railing, first determine the correct angles for the vertical posts using a T-bevel and a magnetic level attached to the post. Use a protractor to find the precise angle needed. Cut the metal tubing (2x2 inch for posts, 2x1 inch for top rail, 1/2x1/2 inch for horizontal slats) using a metal chop saw with a diamond blade. Weld a small base plate to the bottom of the posts for stability. Use a welding blanket below your work area to protect surfaces from sparks and splatter. Tack weld each individual piece (posts and slats) into its secure place on the staircase, ensuring everything is plumb and aligned before fully welding. Once the welding and grinding are complete, degrease the entire railing with acetone to remove any oils or grease that could interfere with the paint finish. Apply an automotive self-etching primer, designed for bare metal, followed by an automotive matte black finish paint. This automotive-grade paint offers superior durability. Once the paint is dry, the railing can be carefully installed onto the staircase.
Goal: Fabricate and install a durable, custom metal railing
