I had a project a while back that i'm just now getting to make a story of.
I had a project that involved modifying an existing steel grinding fixture for my rotary surface grinder.
the fixture wasn't hardened, so machining was a good time!
the fixture is about 7" OD. way too large for my working machines!
i took it as a challenge to accomplish the feat.
i gave the shoulder tap to my vintage 9X22" Hercus ARH Lathe...
a 6" scale is held up to the work
this is an after shot, i didn't think to take a before shot.
I parted a ridge off of the fixture that was about .375" thick.
then faced the end.
i then cut a recess .200" deep into the fixture and made a step inside the fixture 5" across.
heres a side view.
i drilled the spring pin bore after the lathe work was performed.
i used the industrolite M500 to bore the spring pin hole with a 4 flute carbide endmill to the planned depth of .375".
a conventional drill bit would not have been able to be used due to the proximity of the spring pin to step bore and where it's location was needed.
i remounted the work on the lathe for photogenic purposes.
the finish was smooth as silk,
i have a lot more respect for the lil Hercus, it can make some beautiful work!
thanks for reading!
