CART-FOLDINGThis foldable trolley took me to carry inflatable boats. The one sold in stores, takes a lot of space, and keep it in a rubber boat is very nice and stick out of the wheel, and cargo area, and its emphasis. My truck is all going, making it very compact. Now she’s well positioned in the pouch under the inflatable boat; the boat to her place. Storage is also convenient: it just hangs on the wall. Several options hinged and sliding knots fixed in the working and folded, was made in metal. The most reliable was the last that showed his successful three-year operation. However, the load more than 32 kg to carry was not necessary.
In the manufacture of focus not suggest doing it from a pipe with a wall thickness of less than 2 mm, because when you ride the bus on sharp turns it just grips the side load.
To make frame, you need to first draw on paper the pattern is life-size and they are as Plaza when bending pipes. When docking elements truck parts should be first to grab each other by two or three points, and then welding completely, otherwise the frame will “lead”, and straightening can significantly disrupt its appearance.

All seams and burrs carefully stripped and zapolirovan.
