Chuck, you're lucky. You saved a fortune on chiropractors. Smart weldor sets the drag on the helmet so it falls when you tip the head forward. The term weldor's fracture actually exists in Chiropractic books describing the neck injury common to the trade.
Nola, being you're a kid, I'll make it real simple. That goober is full of CRAP! He claims to be a Union Elevator Mechanic, and if he was playing Mr Efficiency increaser on the job he'd have 4 flat tires every day till he learned to work the Union Brothers way. Also consider elevator shafts are very special places in terms of what can be done in them and by who. There is very little welding done inside of a shaft because it is a high risk location. Also note the brand new leathers he's posing in. No weldor worth his lunch bucket would pose in spanking new leathers and expect to be credible. The guy is getting beat down on Welding Web, and there ain't 20 weldors on that site I'd call mechanics. The more he defends the worse he gets hit.
Look at his site and he's advertising "hardened tip" which is a dangerous thing to have on a chipper because it increases eye injury potential, and "shock proof" spring handle. What the hell kind of shock is he expecting?
The construct of the hammer is compromised badly when the pipe nipple holding the light is welded in, and the light should be tight to the head, not back a couple inches. That head is going to fly when one of the 2 welds breaks, and it will.
Sad part is he ain't smart enough to know he's getting beat to death.
He ain't even smart enough to remember he was asking for advice on how to make the welds look acceptable on another board 2 weeks back.
