    problem with 4 1/2\" grinder...

    ok guys... this should be pretty easy, but for some reason it has turned out to be a bit more of a challenge.

    I wore out the grinding disk, and I am trying to change it. well pretty simple and straight forward right? they provide you these stupid weak little wrenches that are extra narrow to do this with...

    well here is my problem; the disk on so tight right now that I bend the little wrench, and I cannot find any of my other tools that are narrow enough to fit in there.

    anybody have any recommendations??? /forums/images/icons/crazy.gif/forums/images/icons/blush.gif

    There should be a shaft lock button on the topside of the gear head. If not I've broken the remaining part of the disc with some vise grips...this would be last resort though!

    SMILE! Those little wrenchs are about useless!

    Same as Rene said, or use some chanle locks.

    Or if it's really bad, chock up the nut in a vise, engage the lock and turn the grinder.

    it'll probably be monday until I give it another shot. my wife and kids are outta town, and so I'm watching my son (he's autistic). we were outside for awhile today, but his patience wore thin about the time I started working on it so I had to abandon it.

    hey twiztid there was no lock on the thing anywhere, but your little vice trick worked like a charm! /forums/images/icons/smile.gif this has the center bolt on thing with the two small holes, and I don't have the tool. well thats never been a problem cuz I can get a good enough grab in it with my hand to break it loose (unless the wrench won't hold it like today)...

    well I put the disk in a vice, took a small punch, and put in in one of the small holes and pounded it off. now when I run across this again (I'm sure I will) I will know how to get it off.

    Grinders have a tough life...I prefer Makita, Walter or Bosch. They are considerably more money but will last long enough to make the price worth it. I have a 15 year old Makita 7" grinder that's never given me any trouble...

    I just got a Porter-Cable 4.5" grinder and it kicks but! Lean on it harder and it just melts the steel away without slowing down!

    I burned-up my last grinder (super-Cheep), bought one double the cost of the first, when this one goes I'll step-up and get a Makita.

    I don't know how I lived without a 4.5 grinder.

    One of the top three tools, very usefull for anyone doing fabrication work.
