Customer has a 2'x3'x2' complex casting that had 2x 3/4-10 holes, 3" deep full of oil and dirt that were stripped and had broken bolts. One bolt had a broken easy out 2" down.
Welder decided to just pour the wire feed to it and fill it up in one shot, bolt, easy out and all.
Course its harder n' the back of gods head now, with no space to move the bolt holes, no space for a through bolt either.
Its one of those projects that will come out on a Saturday, has to go back in Sunday afternoon for Monday shift.
The bit of reading I've done says that once it goes hard, anything other than a slow controlled cooldown won't help reduce the hardness by much.
I don't have access to an oven big or hot enough to throw the whole thing in.
Any practical way to get it soft enough to drill and tap?
Thanks!
