It was an enormous asspain and took forever.  My punch-a-ma-jig did
one hole at a time.

It's different-  there are fewer holes (one per frame), but they need
to be punched more precisely.  I made a mask and die arrangement out
of tool steel.  (I had access machine shop at that time.)  And then I
made a clip-keeper arrangement that let me move the film by a set
distance (one frame) without (obviously) having to see it.

I never managed to get it to be completely satisfactory, and I ended
up selling the cute little camera I wanted to use with it.  (I was
trying to make 1600-speed 110 film, which, well, doesn't exist-  it
only comes in 100 and 400, per spec.)

Yeah, I'd recommend going to medium format-  the slitting is
relatively easy, the punching is a buttpain.
