Today I started a plan to build an adjustable rack. I like the look and performance of Thule stuff but something occurred to me as I looked at the design.
I used to compete in bodybuilding, my training style was more like powerlifting. The racks we used for squats etc. could handle a 500lb drop if necessary, and I tested those things in that way for around 20 years - I know they work, and have never seen a pop-pin actually fail (also worked as a tech in that industry for a long time).
I plan to modify a used cage (found on kijiji, or something like that), so that it is fully adjustable. I'll post a picture of the type of rack I intend to use. The only significant mod would be to the length of the sliders because I'd have to turn the tubing so that the holes are facing each other from each side of the box. Once I have the measurement for the piece of 2x2 I need it's just a matter of getting that welded to retro the mechanism. All that I need are the 4 uprights (cut to the length of a Thule setup, roughly), and the 2 adjustable sliders. Will not be very expensive. I can powder coat to match the colour of my truck.
I work in design/build and am pulling away from the amount of actual on-site building that I currently do. I'd like to be able to put a decent amount of 2x6 2x8 etc. on it without worry and get rid of my trailer. Most of our materials are delivered, so no real need for pulling a trailer anymore.
Going to think about how to mount it.
