I don't think they're made. Spiral blades are primarily for fretwork
(especially veining) and pinned-end blades would not work in this application.
What you want is a plain end adapter. The answer is yes. I've seen them at
wildwooddesigns.com, sears and woodcraft (I'm sure there are plenty of other
sources). May I ask what kind of scroll saw it is? There's very few that
don't accept both pin- and plain-end blades.
