   All you need is a collar or sleeve bushing at 1/16th thick walls with a 5/8" I.D. and a 3/4" O.D.

             If you can find the right size material at the steel yard or other place you can cut them as needed .

   McMaster-Carr has drill bushings that will probably work, catalog page 2602.

   Try bronze sleeve bearings

   Get bronze sleeve bearings, 5/8" ID, 3/4" OD, and available 1/2" to 1 1/4" long.  They should press easily into place, they may just slide in depending on the tolerances of the cutter's bore.  These bearings are porous and oil impregnated.  To prevent the oil from being spun out in use, soak the bearings in a few changes of paint thinner and dry them out before using.  They are available on line from MSC, and probably any other industrial machinery supply house, and best of all they cost less than a buck each.

   I wouldn't run really large diameter 3/4" bore cutters on a 5/8" arbor, especially on an old machine.   With a large cutter there is a chance that that the shaft will flex and vibrate and in the worse case the shaft or the bearings might be damaged.

   Thanks!!!

   Thanks for the guidance. This is my first shaper and since I realatively stole this at a yard sale, under a buck each  for the bronze bearings will more than make up the difference when buying the cutters I need. I'm not looking at large cuters, just rail and stile bits for raised panel cabinet doors. I truly appreciate the assistance from all on this... The shaper powers up and runs very smooth with no delay in reaching maximum speed.. I think I really lucked out with this one...

   The oil impregnated bronze bearings are easily found, are available in seven lengths, and are inexpensive.  I did find that the MSC catalog does have a solid bronze bearing in 5/8" to 3/4" but it was only available in one length, 1/2" and it cost twice as much as the oil impregnated bronze bearings.  Somebody may make steel or brass bushings for this purpose but I couldn't find a source for them so I suggested a good, though not perfect, alternative.
