Yes, right. Bill's article was where I got the idea, too.

I think I might work out (on a piece of wood scrap?) exactly what size 
mortise will work with the .137 pins plus your thinnest bushing cloth, 
and make up a file to fit that. Maybe if you ground off the ridges for 
about 1/3" on one of them, and beveled the end somewhat you could use 
the other the other file to enlarge the mortise (one side, then turned 
to the other side) so you wouldn't have to bash your way in.
