I have a magnetic vise about 6x12 or there abouts and it does not do any thing when a rotate the lever. I just saw the price of this vice new and now I want to see if it can be repaired. I just got a small manual surface grinder and would like to try grinding a few things. The first thing I want to grinde are the shanks on 1" taps form .8 to .8756. I will mount the tap in a wirly gig and grind away. I have a few questions. I am heat shrinking on 3 ft extentions.
1 should I use a coolant, water soulable oil and water.
2 Is this going to take a long time.
3 What kind of wheel should I use? I am grinding High Speed Steel.
4 How much volume of fluid should I use.
5 How heavy a cut can I take . Don
