Introduction: $25 Steel Roof Rack - No Welding
Here I will walk you through my $25 weld-less roof rack.
I woodwork for a living and I was putting a lot of wear on my OEM Subaru Roof racks that are made from aluminum. One day I slightly overloaded the racks and took it over a speed bump and the racks were completely ruined. I looked online and replacements were around $250 and I knew I could build my own for way less!
- Tape Measure
- Marking tool
- 3/8" drill bit
- Power Drill (I used a drill press)
- Metal Saw (I used an abrasive chop saw)
- 1/2" Socket wrench,
- (2) 2-3/8" Galvanized Fork Latch- $5.72 - Fencing Section
- (8ft) 1" square tube steel - 16ga - $5.50 - Hardware - MUCH cheaper at a metal distribution store (King Metals, Metal Supermarket in USA)
- (4) 5/16" x 4" Galvanized Carriage Bolts - $4.32 - Hardware
- (4) 5/16" Galvanized Nuts - $0.72 - Hardware
- 1" Plastic Tube inserts - $0.40 - Metal Distribution Store
- Spray Paint (I powder coated)
Step 1: Clean and Cut the Metal
First remove the preliminary layer of oil off of the metal with acetone or mineral spirits. Once the metal is cleaned, mark at least 4" longer than the width of the roof rails of your car. My pieces are 45" long on my Subaru.
Mark at 45" and 90", cut using a metal saw. I used an abrasive chop saw for this step.
Step 2: Mark Rail Locations and Drill Holes
Due to the variation in the rails, make sure to measure the exact location of the rails and where your bracket will overlap. As you can probably see, I thought I had the measurements calculated correctly but in practice they were off. Definitely place the rails on top of the car to see exactly where the rack will intersect with the rails.
After you get the exact location, mark the middle of the metal and drill through with a bit that is larger than the 5/16" bolt, I used a 3/8" to account for the powder coating in the upcoming steps.
Step 3: Deburr Metal and Second Cleaning
Using a rasp, deburr the edges and any drill blowout. Clean the metal again before painting or powder coating with acetone
Step 4: Protect the Metal
I have access to powder coating equipment to give my rack a professional finish. This can certainly be done with less, a simple spray can with an outdoor level protection should be perfect.
Step 5: Attach Rack to Rails
First insert your caps into the end of your metal to prevent water and reduce drag.
Next using the brackets from the fork latch, insert the bolt through the bottom of the bracket and up through the metal on both sides. Insert nut over the bolt and tighten to the car rails with a 1/2" socket wrench.
You are now complete, I hope my Instructable will help you build a simple rack of your own. Thanks for looking!
