this part is thirteen thousand dollers to make, we are repairing it for fifty five hundred dollers. look at the little itty bitty spot of corosion inside the bore. that caused this part to be pulled from service. it might be a little hard to see, and i put a business card next to it for scale comparesion. its some kind of aircraft part. i have to machine the diameter that has the corrosion over size then we will spray it up and i will machine it back to blueprint tollerances.
