Take your good file and get some iron filings and sprinkle them around the crack and put a magnet underneath or near the crack. the filings will line up one way on one side of the crack and another on the other side of it. My experience with crack finding is to put diesel fuel on the crack, let it soak a bit , wipe it off and rub chalk over suspected area. This will tell you truthfully. Center punch slightly past ends and drill 2/3 thickness of parent metal. Chip or grind out crack same depth and weld like the guys are telling you. If you cold weld it, peen welds good with a 16 oz. ballpeen hammer (make dents in weld, it kinda stress relieves it) Don't weld over 3/4" at a time. If crack is long, lace it (grind cross grooves in it and weld them first. ( helps to keep it from moving around. Don't weld in a draft. Do weld backstep. If weld is porous, grind out and do over, (weld crack is contaminated with oil.) Thats why you grind 2/3 through crack. Do put asbestos or ceramic wool over when done. Do put a heat lamp on it to cool slower. If it is a one shot deal like engine block use Certanium or Eutectic rod. (expensive but best) If you pay strict attention to this, even a novice can succeed if the cast is weldable. White iron and cast with a lot of carbon in them are awful hard to weld. They should be brazed. Now you're as smart as I am on the subject. Sorry for the long post but this will work and I'm shooting for the long poster of the year award. Grin

To the newcomer planning to restore the machine, this means you have everything you need for the moment (something to sit in the shop and just look at for awhile while you read the books). To the newcomer that wants to get out and use the machine for field work, you may have already hit a major roadblock. That is the dreaded "proprietary hitch". With the exception of the
