EGT sensor installation - side view

Installed the DiPricol "short" EGT probe.

Center punched where I wanted the hole. Started with a 1/8" drill bit and worked my way up to size "R" or 21/64" in three steps.

Used a stubby ratchet with an 11mm 12 point socket for the square end 1/8-27 NPT tap.

I also used cutting oil because I wanted nice clean threads.

Installed the adapter and probe using hi-temp (1800F) copper anti-seize.
