Senior engineer at work (University Graduate) asks me to have a stainless steel component fabricated in our workshops.
I send the design & order details & 2 days later receive the item.
One hole is 10mm.
"Thats the wrong size", he says, "it should be 8mm"
I told him the only way to fix it was to send it back to the workshop, get the hole filled with weld & re-drilled.
"Can't you just drill it out?" he asked.
