The company I found locally has a water jet set up and If I reshaped the hole
there was too much metal gone for my comfort. We could have welded in the
holes...but after discussion we decided to start over and it will be perfect
this time. And half the cost of the original job!
The water jet system is quite the machine!!
Thanks...
Rich
