HP67 : repairing a keyboard

[albertofenini]

We wanted to share how we repaired a keyboard a couple of weekends ago, it may be useful for someone else.
We were restoring our HP67 and while cleaning the unit, we discovered that the last (first) row
at the bottom of the keyboard was broken.
The metal bridges were so stressed and thin that they were breaking apart.
Using an exacto knife and been careful enough not to break it we carved a line from an old HP45.
We removed the old, cleaned with the help of a a pen rubber and we positioned the new strip.
Having cleaned with some sand paper (1000 grit) the small holes left from cutting the strip off
the 45, we were able to do some soldering to help keep in place the new strip.
It worked very well, and now the keys have the original click and feel like new.
