brazing cast iron

Postby coppersmythe » Mon Mar 04, 2019 8:40 pm

hello from the cool deep south . i have a "new" cub that has had a tough situation . the head has a freeze crack , not too bad ,but , more than "easy" . i had to wrestle with just replacing the head ( i have a good one )and dealing with the possibility of broken head bolts . OR , brazing the crack . i have pretty much decided that brazing is easiest , just wondering if its something y'all would like to see . gas welding is kinda going out of vogue , but it still "works " well . the crack was repaired with JB weld , i guess it worked. for a while . coppersmythe.....................................PS: i learned gas welding from my dad , we welded " miles " of stainless steel pipe at the colonial sugars plant in gramercy , la. , early '70s ( i was 17 ) . dreaded every minute , but, i wish i could thank my dad , today , for the experience ...................................................

Let’s see it! I’ve seen my dad weld with a torch and coat hanger.

Brazing is awesome if done correctly, it’s also a talent like anything else. A man with your experience probably has it mastered so please share.

I remember brazing a broken cast iron bell housing with my dad. I have seen Ken Kammerer (of CVA fame) weld a cast iron manifold using heat sink wool, cast rod and cast welding flux and a torch.

I for one would enjoy seeing you document the process.

I learned the hard way that coathangers today are NOT as good of steel as the ones my dad used ;)

I'm cheap, but I do have to buy antifreeze. I don't call it "suffering from cheap", I'm just plain cheap! 15 degrees here, this morning.

I braze cast iron all the time. My dad did a little mild steel before we cot the arc welder. In high school I gas welded up a table for the classroom. It was still in use for several years, until they stopped the shop/ag classes at the school. thanks; sonny
