I have an older 9 amp circular Skill Saw. It’s making a grinding noise on start up and when slowing down. The brushes are still approx. 1/2 in. long. Any thoughts whether I can repair myself or if I bring it into the repair shop what might I expect to be told is the problem? Thanks for your advice – Happy Holidays to all – wishing you all well for the New Year.

Sounds like it could be the bearings on your armature. I'm guessing that you have already checked for blade rubbing or debris in the guard. Better taking it to the shop for an estimate if you don't have experience pulling and pressing bearings on electric motors. If this is a worm drive it could be a gear problem with the same experience needed.
Thanks for the reply Hammer. I've got no motor experience, but at least now when I go to the repair shop - I can sort of sound like I know what I'm talking about - thanks to you.

All portable circular saws have gears. They use a router type motor and gear it down or it wouldn't have any torque. If the saw is a $100 saw you might be better off running it until it dies. Once they take it apart to see what the problem is it may not be worth fixing and you end up with a box of pieces. It's always better to deal with a repair shop you can talk directly to as opposed to one the local tool dealer sends the stuff off to and you get put out of the loop.
Hey Rick,
Thanks - I know a new tool is not going to cost me more then $150.00 or so - but this saw I had earmarked to donate to a local woodshop high school class - I wanted to spend a few bucks if that's all it needed to bring it up to speed. However it looks like repairs aren't going to be cost effective. It's a tool that I wasn't using but hadn't trashed - was kind of hoping for quick fix advice - but it seems that's not possible with the age of this saw.
