For only 20 sets, the custom cutter stack for a horizontal mill

I used the horizontal mill and an index head to make a
replacement gear for use inside a differential vertical plugin. I think
that I posted a web page about the project a couple of years ago. :-)

If he is stripping a frame to make each, he probably would need
the front and rear panels too. The front is likely an injection
molding, but the rear is pretty simple sheet metal work, IIRC.

Well ... the QA stamp could be forged, too. :-)

The empty chassis for the TM-500 plugins would be a nice
starting point, except that they are not long enough. (I considered
using one (which I have) to make a test extender for the 'scope
mainframe, and this is how I know this.

Custom machined parts would offer him a better choice of mounting
certain parts -- such as those which need heat-sinking.


Are you a member of the Yahoo TekScopes group? Some of the people
there were engineers at Tektronix.
