I got tired of my shop vacuum catching on every machine in my shop as I pulled it across the floor. Frequently, the hose would pop loose and add to the frustration. So I took a lesson from amusement park bumper cars and constructed a hoop around the casters. Now the vac bounces off obstructions. Build the three-ply hoop, as shown, and screw or bolt it to the caster housings. Then take your newly remodeled vacuum out for a spin around the shop.
