So my favorite drill press was missing a handle and the other two were loose or bent. I like the old hard working machine and decided to build new handles out of 3/8" steel round bar. When I welded them into the handle holder mount on the drill press I noticed the metal was acting odd and not penetrating. It acted like they are dissimilar metals. As I was wrapping duct tape around the ends of the handles to make grips, the handle popped right out in my hand... with the weld still attached!
I was able to make decent looking welds but turns out it only penetrated to the handles. I ground the metal down prior to welding. While welding there was no smoke or unusual fumes.
The handle holder is magnetic. What type of metal would they have made it out of that I cant weld to it?
Now I am really screwed. I drilled out the threads in the handle holder with plans of welding in the new handles.
