It may not work for your scrapers, but I have made file handles by
drilling a hole into the endgrain of a dowell, somewhat smaller than
tang of the file, then using the file tang itself to ream the hole.
Grind the edges of the tang to sharpen them if necessary before reaming.
Stop reaming when about 1/3 or so of the tang is still exposed then
tap the handle on. (sometimes the handle-to-be breakes at this point)
On some of these handles i made a ferrule from a piece of copper pipe or
by drilling a hole through a copper pipe cap.

Often wrong, never in doubt.
