buddy i had a customer have this same problem, he had it welded, the next harvest when he went out and ran a rock threw it, it screwed everything up. i had to replace, new spider, all new raspbars, and filler plates, new concave and a new beater grate, if you gone taking it all off that far you might as well get a new spider, but the worst thing is if you do that you have to take th shaft out on the side that you broke that spider. same spider broke for him. and that shaft sucks takes out, a lot of panther piss
