Clamp for attaching a paint roller to a leaf blower to make a toilet paper cannon/launcher for pranks or science demonstrations. (Bernoulli's principle)
The clamp consists of 3 parts, a mount for the blower nozzle, a mount for a paint roller, and a middle section to hold it together.
The clamp requires eight 5/16-18 x 1-1/4" hex bolts, and eight 5/16-18 nyon stop nuts.
the nuts are designed to fit into a recess in the clamp to keep them from rotating, so that assembly only requires tightening the nuts.
This clamp was designed to fit on a Kobalt cordless leafblower, check the dimensions of your leaf blower to see if the blower nozzle will fit in the clamp - you may have to redesign the nozzle side of a clamp for a differently shaped nozzle.
