Back in the Altair days, there was a company called Oliver Audio Engineering
that made a small optical papertape reader for hobbyist use.  You pulled the
tape through manually.  The read strobe was generated by sensing the sprocket
holes.  It would not be difficult to recreate this device, or something
similar.

I think you'd need a machine shop and considerable skill to make a punch from
scratch, While it would not be beyond the capabilities of those folks who build
clocks and engines from scratch, you're best bet is to try to pick up one on
eBay.  They show up with considerable regularity, and usually go for $100-$300.
