Happy Spring to everyone!  I've been plugging away with a Leabarjan #5.
I got it last April and have only really gotten to spend some time with
it recently.  It's taken some time to calibrate it well and I believe
a few parts are still missing to keep the tracking going well, but I'm
improvising solutions.  However, I'm starting to have "hanging chads"
and, if the hole punching isn't tedious enough, I now am going back
over the rolls with tweezers to tug these chads off.

I took the punching die apart and noticed there is a slight angle
to the punch.  I tried to follow that angle while dragging the punch
face-down across a fine grained aluminum oxide sandpaper.  This didn't
eliminate the chads while punching.  I'm nervous to do it wrong, so
I only slightly sanded it thinking it just needs a touching up like any
good tool does from time to time.

Any confident advice to sharpening this punch and die would be much
appreciated.

Yours in perforations,
Seth Brown
