I created a tool that allows the use of self-adhesive sandpaper attached to a cone fitting with 1/2" hex drive for use in power drills, in order to sand the inside diameter of metal tubing when flared for AN fittings.
When converting to AN-flare fittings, the metallic tubing can be flared using a special flaring tool to achieve the correct angles on the tubing. In the event of corrosion or burrs on the ID of the tubing, this sander can be used to smooth the flare at the correct included angle for a proper fit.
The accompanying template allows for quick and precise cutting of self-adhesive sandpaper sheets.
