I am a big power tool aficionado but can't (off the top of my head)
think of when I've used them for unintended purposes. I have made slight modifications on rare instances but only if necessary to do a specific job - then restored back to original condition.
Just when I thought I have every single tool a man can have, I find an excuse o buy another one. Guess I am a tool addict
example: I must have (no exaggeration either) 35 - 40 hammers of all different types and last night I bought a Shooboy Midnight Pro. Just in G Smithing hammers alone, I have at least 7, but found a need for a Shooboy anyway.
I recently upgraded 4 different power tools by selling my older cheaper ones and replacing them with Milwaukee Electric Tools.
Left Bladed Circular Saw, Rotary Hammer Drill, Orbital Jig Saw, Angle Drill.
Added: I do remember one tool I did permanently modify........ I took and old cordless Screwdriver that had dead batteries and converted it to run on my DC voltage converter. I use it at my workbench when driving lots of long Machine Screws. It had endless power now and since it's a Bench Tool, I do not mind the cord.
