I've found that site extremely helpful --
Have a bench-top table saw and a WorkMate worktable that are almost as old as that shaper. Decided to refurbish them both a while back -- had no problem finding numbers for even obscure little parts.
Out of curiosity -- I just checked the shaper that was asked about.
They have exploded art and part numbers - but no on-line version of the manual. They did suggest contacting
publications@bdk.com to request one.
