When I started woodworking last year I was doing mortising with a cordless drill and a cheap set of chisels. Based on the advice of my fellow lumberjocks I eventually tried using a plunge router with a spiral upcut bit, still cleaning up the edges and corners with a chisel. Then, the other day I was browsing craigslist and saw an ad for a Jet Mortiser for $140. I quickly called and drove out to see it.
The mortiser was in pristine condition, only used once and came with three chisels. The guy that was selling it had decided he didn’t like a benchtop model and upgraded to a floor model.
