Why not- you know- make some effort to understand what the hell you are doing?

I spent all day yesterday repairing a machine that was damaged by the serviceman who was supposed to be repairing it. Look: if you have a 18mm deep threaded blind hole, and you have a 20mm long bolt, it’s not going to tighten, see? No matter how much you want it to. And continuing to tighten it afterwards? Well, that’s going to make it worse, because then you’ll yank the threads out of the aluminum body of the part. OK? maybe you should try baking, or something. I don’t think you were cut out to do mechanical work.
