I, too, would like to find _both_ Oslund machines!  Bill Spurlock has
a substitute that uses a router and a drill press.  It may be worth
a look for you:

  Spurlock Specialty Tools

The work I have seen come out of these tools is high quality, although
it takes a little longer than with the Oslund tools.  (It is quicker
than by hand.)
