Rocker pin extraction and insertion made easier

Sometimes the rocker pins are terrible to get out without the proper tools.
They are either stuck by interference or by vacuum.
To get the vacuum part sorted (pushing them in mostly) I drilled 5mm holes; that helped a lot! and if a pin is accidentally put in the wrong way (threaded end first) it is still possible to remove the pin by tapping them out from the other side with a drift.

The interference fit I sorted by grinding 3 sharp edges on the end of a Pantah rocker pin (slight longer than PT) so it looks like a reamer. Put it in the battery drill and on slow revs carefully and gently go into the holes. Eventually the holes are reamed sothe original rocker pins can go in and out with very little effort.
