Summary: Very new machinist student gets 3/32 set screw very stuck in apparently poorly tapped hole in R8 fly cutter project.
Now, I'll give you the long winded version with steps I've taken in CAPS.
Hopefully I've uploaded the photo correctly and it is adequate. My steel rule is at school and my teeth held the flashlight for the photo.
I simply hand tightened this set screw tightly until it stopped turning. After that, I've torqued several Allen wrench wrenches both gently and with shock. -and snapped them off. THE ALLEN SOCKET IS STRIPPED.
I've soaked it in LIQUID WRENCH for minutes (and attempted turning it before it was stripped) as well as days. I'm guessing that straight penetrating oil would have been better, but I couldn't find any at the stores I looked at.
My father-in-law and I tried the steps for an EASY OUT, but I warned him that set screws were grade 8 hardware. Obviously run of the mill drilling didn't work.
The R8 fly cutter body is case hardened 4140 steel. Though I know it is extremely inadvisable, I even tried TORCHING IT.
Thank you for your consideration
