New to me drill press repairs

[Cord]

Crack goes from edge to edge so nothing to drill, it will get beveled. Going back and forth on brazing or using nickel rod. Based on my buddy that does this type of work all the time I'm leaning towards using ni55 rod, plus he already has some I can use

Got it appart, now it's time to clean it up and grove it out with a carbide burr.View attachment 587348View attachment 587349

I do that weld with a single pass of nickle rod without thinking twice.

I'd vote Ni99 if you want to stick it. Or Hot Spray Powder. Or Tig or Braze with Ni Ag. Much nicer than Bronze. Easy fix.

Why do you suggest Ni99? this is a decent size casting and will need some cleanup/machine work possibly. Spray powder isnt really the right process for this repair, it has structure, not just closing up an exhaust manifold or head crack.

I think I'll be going with the Ni55 for this one.

the whole point is using something that can stretch, else the weld will crack on cast iron unless the part is heated in an oven first, and then put into an oven and allowed to cool slowly. without the oven, either bronze or Austenitic stainless steel is recommended, with the Austenitic stainless steel giving a stronger weld..

Brazing, if done correctly, will be the strongest repair. The nickel rod would work OK too as long as the cast is of decent quality. It won't be as strong, but likely be fine.

Pre and post heat are given, I have a decent size oven capable of 2400*f so no problems there.

I've done repairs on cast using stainless and brazing, not much using Ni rods, looking at the casting and application guides the Ni55 seems to be the best fit for this repair.

Or you could just give up. I would came haul away the scrap for you.

I'm familiar with lock-n-stitch, they recently completed a 3year project at my work so I got to talk to their reps quite a bit. Good system but I definitely got the feeling they would bash any other system of cast repair.
