I had to get a few more parts to complete the kits and make it easier to get good results.
An extension for the counterbore aka spot face cutter was needed so the drill chuck would clear the main journal.
The 8x1m tap needed a 1/4" by 6" socket extension, a tap handle, and two layers of 5mil plastic to take the extra slop out of the tap to extension fit, but loose enough to let the tap find it's way square into the bore.

It's fun to do but you need to keep track of the steps, and take your time.
So on with the show...
In the interest of accuracy in the field the block was shimmed up level.

The bushing fixture is set in the lathe drilled and tapped out main bolt.

~~~~~~~~~~~~~~
The Dewalt 106 drill has a ball level in the back of the handle so it is possible to drill fairly perpendicular freehand.

~~~~~~~~~~~~~~
Picking a spot @ a 1/4 drill bit width from the edge using medium pressure and nice and slow with the drill at only about 600rpm the cast iron cuts quickly and easily.

~~~~~~~~~~~~~~
The block wall into the oil gallery is about 3/8" or 8mm thick at this point, and the gallery is around 1/4" or 6mm wide, so be careful and let up when the sound changes and punching through is imminent.

~~~~~~~~~~~~~~
Next the counterbore is run at half speed or @1250rpm with light pressure to cut it flat, and then just a touch at full speed 2500 rpm to smooth the surface.

~~~~~~~~~~~~~~
Drill again..
The fixture is repositioned by wiggling the drill bit back and forth to find the center, and tightened in place.
Drilling the 7mm pilot hole for the tap is tricky as it tends to grab in the 1/4" hole.
Very very light feed pressure, half speed, and the chuck not so tight so the bit can spin in the chuck when it grabs instead of snapping the bit off.

~~~~~~~~~~~~~~
Now the hole is faced, piloted and ready to tap.

~~~~~~~~~~~~~~
The fixture is left in place and used as a guide during the threading operation.

~~~~~~~~~~~~~~
You'll feel the tap hit bottom and stop, don't push it and ruin the threads.

~~~~~~~~~~~~~~
The pointed tip of the tap is ground off to get the threads further down the bore all the way into the oil gallery.

~~~~~~~~~~~~~~
The finished product.
