I don't recall the last time I broke a fully functioning prototype. It's not a metric
I track because it is a prototype.
Failure is expected during development; whether it goes into the waste basket or is kept as reference
is anyone's guess.
This particular tool will be a template for a megajig
that will forge endcaps of any (normal) size for chains. The prototypes were just for
two sizes in one module though it will have 6-12 sizes in each of the 2-4 modules. It is similar to the
rivet making tool
because it makes one item in many configurations using modular-ish components.
The prototype worked. There are varying degrees of "it works"
so in this case it functioned enough to prove the concept.
It was good enough to be used on a production piece.
Standard practice is to duplicate the process a few more times for confirmation.
The tool, obviously, will be upgraded but it can serve as a backup.
Or not. Ix-nay on the ackup-bay.
I wasn't expecting failure here but the stamp deformed and wouldn't fit into
the die properly. It can't be fixed because the whole thing is tweaked. I wanted it to work a few more times
but it had other plans.
Whatever is hanging around gets recruited when making prototypes. DIY 5/16" steel mandrel is
a far cry from precision-ground hardened O-1 tool steel
but good enough to test the concept...once, in this case.
It gave its life for the cause. Although a short life,
it accomplished everything before a glorious death.
Now it's useless. Surely it deserves to put into the tool hall of fame.
Sending a prototype to pasture becomes complicated when the item facing
destruction works fine, has hundreds of dollars in
parts, and weeks of manufacturing time. It should be a crime to disassemble
or discard. Such fate awaits my first
wire drawing machine
because its replacement is coming.
