CM91: Ever Play the Game Operation?

Ok so this is Part II of getting Stymied by two stuck screws on the rocker arm cover.  Ended up stripping them with the Lisle's phillip head, so now it was time to call in the Dremel and attempt to re-slot them so we could attack with the Lisle's big flat head.

Only problem was that these screw heads were way down deep between the cooling fins.  It basically became the wrencher's version of Operation, requiring a very steady hand and steel nerves.  Stray by a millimeter on either side and suddenly you're grinding into cylinder head.

This was really my first time using the Dremel for anything besides making some test cuts, and I was pretty surprised by how steady it was and how much fine control you had.  Took my time and let the RPM's do the work, like they keep telling you over and over in the guides.  The tip was the #426 Fiberglass Reinforced Cutting Wheel and I did the whole thing at max speed.

Once in awhile I'd stop and check to see how well the Lisle flat head tip was fitting and whether it was getting good purchase.  Once it felt like it had a solid grip, it just took a couple very hard whacks with the impact driver and each screw came free.


A few shots of ever so delicately getting the Dremel between the fins.  (The Dremel's off in all these shots, of course.)  This is how I got to one screw.

Then the other screw...

Here are the screws after they took their beating.
