    Hello

    Well, there is a first time for everything! Has anyone seen an auger motor shaft snap?

    This 2 RPM motor was lying on the bottom inside a Magnum BabyCountrySide.

    The broken auger motor shaft end was wedged solid in the base of the auger!

    So we took it into the lab and drilled out the middle of the shaft from the bottom and then a smaller hole in from the side.

    With many bangs and taps with an awl and hammer it first started to loosen and move sideways. Then all of a sudden after more drilling with the carbide tip drill press it was free and came out with a finger pull!

    We used the grinding stone to smooth down the auger end, so the collar will slide back on.

    Then we cleaned the stainless steel auger up with the wire wheel and sprayed it down with the Dry Moly Spray.

    The new auger motor shaft slid right in.

    Yup, do that crap all the time. I keep all of my old auger motor I pull so I usually have a spare shaft from about every gear box, so I just cut the shaft, remove the other end from the auger and replace the shaft in the gear box. So I'm guessing that the auger motor snapped the stop bolt on the baby Mag?

    I haven't seen a "drill press" like that in a long time!

    Love the C clamp anchor to the press and work bench. That's got to be one strong motor to snap that shaft. Nice job and pics.

    That sounds like metal fatigue, probably from misalignment.

    The previous auger motor already snapped the stop bolt. :) Where do you get your carbide drill bits?
