Since neither Easy Out worked My next plan was to drill out the hole using the Tap Drill (8.5mm) and Tap M10x1.5 I had bought at PepBoys for another Job that I never did.
Well the Drill was too soft and did not get Far.
I decided to use other Drill Bits that I had to gradually enlarge the Hole.
I did that until there was a sleeve threaded Meatal left inside the Hole.
The threaded Metal Sleeve was pried out and I chased the threads of the Hole with the Tap.
The problem now is that due to my crooked drilling there is only about 50% if the threads left.
That leaves Me with the choice of using it as it is and see how long it will last or installing a Helicoil or drilling it oversized and using an oversized Bolt.
I am going to try to go with the oversized Bolt because that is cheaper than a Helicoil and I already have a Tap and Tap Drill for that. 7/16" is the closest US size that is just a bit larger than the M10 Bolt is.
First I need to see if the Local Industrial Hardware Store has the 7/16" in a suitable Grade first.
So until My Wife gets Home I have no way to get to the Store.
If that does not work all that is left is to get a Bolt long enough to go though that hole and allow acseparate Nut to be put on it.
