I bought this machine from a GSA auction about a year ago. It was one well traveled machine it its day. It has a dealer tag from Star Machinery in Seattle and paperwork with it showed it spent time at military installations in North Carolina and Virginia. Somehow it ended up at the GSA dump in Columbia, MO where I got it.

It was in sad shape when purchased. It had been dumped on its face (I think?). Both of the front handwheels were gone and the table traverse shaft was bent 90 degrees to the side. There was a 3/8" chisel and bit mounted that were bent about 30 degrees from vertical. Amazingly the the important castings were just fine. And it fired right up and ran like a top when I put power to it.

When I took it apart it I was surprised how good shape the bearings, etc. were. It had seen pretty good maintenance over the years. But the head ways were less than perfect. I hand scraped the main casting ways for the head back into better shape and machined the head casting to get rid of some wear. I then spotted and scraped the newly machined ways for bearing. I am very pleased with the results.

I ended up making a new stock clamp patterned after the original that was missing. I also repaired the foot pedal, replaced the two front hand wheels, and made a pattern and recast the table stop mechanism. I also made a couple new adjustable bit bushings to make a complete original set. Lots of cleanup and a repaint and it is now a very nice mortiser capable up punching up to a 1 1/4" hole in softwoods or 3/4" in hardwoods.
