Abrasive Cutoff Wheel.
You can cut through steel with this portable abrasive cutoff saw in a fraction of the the time it takes with a hacksaw.
The design uses 3/8th inch hot rolled steel for the baseplate and 1/4th inch for the arbor-and-motor base. As a result you get good stability, sufficient thickness to prevent distortion during welding and enough bite for screw threads.
Four pages ( 3 sheets - front on first and last, front & back on other sheet ). B & W photos, illustrations, expanded views and instructional narrative.
My plans are from original source materials such as books, magazines and other publications and the pages are carefully removed.
