So, Zach and I have been working on an updated version of The Public Radio, and I figure we're about due for a manufacturing update. So! Here goes:
This is the same progressive stamping die I've shown here, but with some small changes. The locations and diameters of our main assembly screws have changed, and as a result the tool needed to be modified.
The cool thing about progressive stamping is that you have multiple stations - in this case five - to work with. As seen above, the stations go right to left. Initially the screw holes were punched in station one (far right), but now they're being done in station two. Making this change just requires removing four punches and then adding four new ones + corresponding holes; the old holes are simply left unused.
We've got a few other updates coming up, including visits to a few factories and a new assembly/tuning management process. Stay tuned :)
