Homemade Sanding Attachment

Homemade Sanding Attachment FARM SHOP Handy Hints Steven Troyer Millersburg Ohio: My grandpa converted a freon tank into this portable air tank He attached a quick coupler that s used to fill the tank with air Then he screwed two male coupler ends together to fill it from a supply air hose Works great for airing up low tires in the field or operating small air tools When converting you have to be certain to eliminate all gas inside the tank You shouldn t put over 125 psi in a converted tank like this Grandpa also made this sanding attachment for his 1/4-in air drill that works great for polishing the inside of any hole He made it out of a 3-in long 1/2-in dia cold-rolled round steel bar with the end turned down to 1/4 in to fit into the drill chuck The bar has a saw cut endwise deep enough that I can fit a strip of 1-in dia coated sandpaper in it The strip of sandpaper wraps itself around the steel rod Centrifugal force pushes the sandpaper out - it actually does a nicer job than I can with a file The sandpaper is the kind often used on lathes and comes in up to 100-ft rolls I use several different bottom dies with our hydraulic press The one shown in the photo is made from 1 3/4-in dia 6-in long rounds set 4 in apart on a 1/2-in thick steel plate My 50-ton press can bend 1/2 by 6-in bars on it Top dies have to be made according to the configuration of your press A square bar could be used up at 45 degrees if sufficiently supported vertically
