  • Help needed: seized wheel guard studs

    Hi all, †


    I am presently restoring a rusty old Delta 14” bandsaw. So far, penetrating oil and WD-40 have helped loosen most everything, except the wheel guard studs. They are NOT coming off. I have sanded around them, squirted in PB Blaster and let it sit over night, but they simply refuse budging. I have gently tapped with a mallet, then a hammer, tried a vise grip (carefully avoiding contact with the threads)— nothing works.

    At this point, it looks like heat (via propane torch) is the last remaining solution. If so, would you immediately follow that up with cold water to crack the rust? †


    Thanks! †

    PS: before you ask, the answer is NO, Gustav has not been helpful at all. He just lies there mocking me.

    I would say no to cold water. Heat it up with your torch, and try to move them when they are good and hot.

      I assume you are double nutting them and using and impact to try to get them off?

        Mike, there is no nut to grab onto. Impact? Do you mean the tapping? †

          put two nuts on the stud and tighten then against each other. † put a wrench on the back nut and loosen
          if heating with a torch, do not heat the stud, heat the material around the stud, remember heat expands steel( and every other material)

            If Steve's suggestion does not work, leave them on. † If you put a lot of force on the stud you might end up bending the casing.

              Be careful heating cast-iron - a big temperature gradient can cause cracks so do it evenly and gradually if trying.
              Apparently best loosening oil (YMMV) is a 50-50 mixture of acetone and automatic transmission fluid. Acetone can remove paint though. Did you get the PB Blaster on the threaded area the best you can?

                I ended up using a pipe wrench on the smooth part of the stud. Any marks can be filed smooth as the smooth section acts as a spacer

                  Re: Help needed: seized wheel guard studs

                  Since the torch method has the potential for damage, I will try double nutting. Thanks for explaining what it is. †

                  Yes, PB Blaster in deep. †
                  Acetone and transmission fluid mix? Thanks for that! †
