Just a word to the wise.... If you do this mod,,,, remember not to put you magnifying light quite as close to your work as you use to...... if the blade brakes, the arm will pop up it will be popping higher than it did before and BAM.....! Almost sent the light right into my nose!!! Cracked the protective piece over the light bulb....! be right back,,, got to take a shower and change my pants...
