Fixing hole in side of block

[hagrid]

Haven't see a snap of Joe's broom yet...

* Are you sure the water jacket is intact? Wasn't cracked or broken when the main hole was made?
* A propane torch by itself won't be adequate to braze that, but it might be useful to maintain the preheat and slow the cool-down. I'm thinking you're going to need help with this.
* I'd use a piece of steel, 1/8" or so thick. Cup it if necessary. Grind out the hole to get rid of any spider cracks and sharp corners. Fit the patch to the hole as closely as possible before brazing.

Joe, having never brazed before,...... this fix will certainly be a stretch.

yes I am listening - grind the hole edges and get rid of the sharp corners, get 1/8 inch steel, cut it the size of the hole, hammer on it and get it the general shape of the area it is covering. Then I am getting a nickel rod and I will melt the rod on the edges of the steel patch and fuse it to the block

Thank you for answering my question. Ok, I need to figure out the brazing gas. How about that yellow tank, I think it is called MAPP gas. Maybe that gas is good enough for brazing?

I woke up too late from the nap after removing the crankcase and whatever else I was doing earlier. Now is a good time to watch videos and find a clip that I can emulate of someone brazing a cast iron block, and see how they do it, and try to get better understanding

If you note Joe's "floor", he does not need to use Oil-Dri.

You don't say? Well true to his motto he must have "figured that out" and is doing better in that department than the brain trust.
