Keeping your canopy secured to the ground is an important detail at the track. I can imagine the chaos caused if the canopy turned into a 10×10 kite or tumble-weed, and happened to make it out onto the straight of the racetrack, or to that tight 180deg hairpin. Safety is paramount when it comes to being at the track, and keeping your canopy on a leash and under control is one of them. I seen this cleaver idea when I was at my 2nd trackday. It is a coffee can filled with concrete with a carriage bolt. Unlike strapping fuel cans to the canopy (fuel cans get lighter as the day goes on), this system maintains the same amount of anchoring weight throughout the day.
This system is inexpensive and effective. When your a privater racing or an avid trackday enthusiast on a budget those are two nice aspects.
- 4 Coffee cans, or 4 1 gallon Ice-cream buckets
- 4 Carriage bolts 8″x3/8″ (Stainless!!)
- 8 Nuts that fit the Carriage bolts 3/8″ (Stainless!!)
- 8 3/8″ washers
- 1 60lbs bag of Concrete (Cheapest they have.) May need 2 40lbs bags if Ice-cream buckets are used.
So why Stainless nuts and bolts, and why so long? Stainless is naturally rust resistant. We want to be able to thread the nut onto the bolt by hand. I have found that the galvanized carriage bolts have a horrible finish, and the nuts being screwed onto the bolt will encounter some type of resistance needing a wrench to spin the nuts on. Stainless steel offers a better fit and finish. This makes set-up quick and easy, no tools required. The reason we need them 8″ long is because we are going to bend the head over. Bending the head over offers a better anchor in the concrete. If the threads become damaged and the nut needs to come off with a wrench, this will prevent the bolt from spinning inside the concrete.
