Thanks btrnuthatch, you did all the welding I just made suggestions and supplied a few rods. I can not wait to see the finished vise. The weld will never chip off like the two part puddy others have used.
I just repaired a Parker 974 swivel base brake set up today and wanted to share this repair since few repairs shown lately were not welded. It is really not to hard especially if you have a TIG welder and the correct rod. Arc rod can be purchased from Eutectic but it is much easier with TIG. The rod I like using is Eutectic Castolin 224, great rod for cast repairs. My TIG machine cost me under $300 from a Denver auction so these machines are out there and the old ones are cheap. Yea the bottle rental, new torch and cooler will run some bucks but well worth it. TIG welding is about the easiest welding out there next to wire. You bring the work to a table, get real comfortable and weld.
I dropped the 974 brake shoe a while back and I threw the set up aside until a member here was asking about a 973-1/2 base he was looking for and pulled this guy out just in case it would work for him. It was the wrong size but decided to finish the repair. I like to groove out as much of the casting as possible, the break still fits accurately for the 9/16 pin. I heat first then tack weld, heat again then tack and so on. Heating the aluminum and adding a leather blanket (my heat treating gloves) along with other gloves to cool slowly, about a good 45 minutes. I flip the piece over, heat and finish welding. Heat and cover again. Really not to tuff. The welding setup and repair only took 20 minutes but all the time really is in annealing the weld. I mounted the piece on a 1/2 piece of aluminum to act like a heat block. Some have mentioned heating up sand or putting the welded piece into a oven but I believe that is a little over kill at least in my experience for these type of repairs. I have not failed yet. The 224 rod goes on real nice and sanded off pretty easy. Just my 2 cents.
Nice repair. It takes a lot of time to correctly weld cast. Can you use a mig welder to repair cast correctly?
