Try using Liquid Wrench spray - it works very well with corroded / rusty fasteners. Thanks n 73,JamesKI5DQ.

When all else fails drill out the set screw and drill and tap the other side or tap the side you drilled out with the next larger size. A little heat may expand the aluminum? Good luck and Merry Christmas

I will second Joe's suggestion. It's the best penetrant I have ever used. If you can't get them loose after soaking them for a while, you can try the appropriate size LEFT hand drill bit. Sometimes the left hand bit will spin the set screws out. Drill carefully or you will quickly mess up the aluminum threads. Worst case scenario is carefully cut them off the elements and install new shorting bar kits as part of the refurbishment. M2 sells them as replacement parts. Merry Christmas es 73,Tim KB2MFS
