Re: Magnetic indicator base demagnetizing
|
I found this youtube video.? At about 13:00 he describes a scratch test to tell if the slug is a real magnet or just a magnetized piece of steel - supposedly the latter can't be removed. I scratched mine and i'm pretty sure it was a magnet, but I decided to play it safe and cleaned it in place.? Took a big handful of q-tips (don't tell my wife) to get all the gunk out.? Adjusted the stop and it now works great.? Some fine steel wool and simichrome on the rods and they look pretty good.? Cleaned up the light rust on the hardware and touched up with some cold blue and oil.
This is a pic from the ebay ad Here's what it looks like now Only downside is I had to get the aluminum label off to get at the adjusting screw and it's pretty bent up.? Even with heat, I couldn't get the adhesive to let go and had to slide a utility knife under it to get it loose. Surprisingly, it's as strong as my Grizzly chinese stand, which is about a dozen years old.? Doesn't come close to the new ones, but I think it will do the job.

Still, to be safe, you could try softening & flushing out the old grease with a wash bottle filled with a petroleum based solvent, NOT acetone. My preference for things like this is whatever version of mineral spirits is cheapest!? |
