AND it saved a half pound or more of nuts bolts and washers. When we weighed in for competition we were 119.5lbs.
Ounce count.

Use caution when welding the frame. The heat from welding can distort and weaken the frame. I believe it can actually destroy the heat treatment of the frame and cause the weld to be the weak point in the frame. Also, a super rigid frame may not be a good thing. I believe the kit frame was designed to flex a little across the corners for a reason. Sort of a built in suspension. To reduce the weight of the steel fasteners in the kit frame consider using 1/4" aluminum rivets. They are strong, light and can be removed and replaced if needed.
