Despite seeing various "homemade" tools posted up I did not realize there was a section for them !!!
If like me you purchased one of the many air shears available a a low price BUT found that your compressor just does not have the volume of air to drive it for more than a few seconds once it gets cutting. Had a sheet of 1.2 mm 1.5mt x 2mts that I wanted to cut a length off and cursed the "air" shear after an inch or two. So looked at the electric options and the price
(tight wad me ).
Then realized that the motor part was not much different than some of the older slow type drills, so set to making an adapter for my Bosch drill. It worked but as the Bosch was plastic cased the adapter did not grip to well. So version 2. Dig out an old B&D or similar that has male thread on drill, female in chuck (think we all have one kicking around
) can't recall what make this was but it needs to have a shoulder that matches the size of the inside of the shear head. Then remove the bearing with it's offset mount from the air shear and screw it onto the drill. Now attach the shear head to the drill and there you have an electric shear for ££'s less than the price of a proper one. These old drills are ideal as they run at a reasonable slow speed suitable for the shears.
