“If it holds, it’s gold”. Right up there with “If you don’t weld well, weld lots” and my personal favorite “A grinder & paint makes you the welder you ain’t!”
You can also use dry sand to cool cast iron just bury it in it let it cool overnight
It will most likely crack again on either side of your weld. Nickle wire or Brazing will hold up longer on cast iron since brass, nickle and cast iron have similar heat expansion rates.
If they hold there gold! I'm going to use that one.
No need to over think it
Should be just fine Doug! Good job!
I likes grand cherokee with selec-trac 2. grinding & welding very handy with metals on cars.
good job man!
my WJ been stanky exhaust and sounds horrible on startup, almost positive its the driver side manifold 😑 nice timing with the video! 😅💯
Haha. Well good luck bud.
You should do a video on reconnecting the exhaust. Especially on that passenger side, it's really tight. I had to do mine a couple of times and had to throw the white flag in and take it to someone to finish it cuz I couldn't quite get it. I'm just curious on how you would do it without taking it to a shop and could help some other monkey with a tool box in the future.
it is really tight. my flag nut is rounded to hell on that side and i had to give up dropping my exhaust during a project. i would love that vid too!
Love your vids. always entertaining & mostly educational.
LMAO at the Chewy boxes, If you own a pet you have a pile of Chewy boxes sitting around.
There was only a few vehicles I've talked to like you did your Jeep, LOL.
My 68 Camaro, Subaru & my 97 Grand Cherokee, LOVE ALL 3.
Great job on the Manifold & I hope your rig gets on the road soon.
OH, Also like the Hoodie, NO STEP ON SNEK, FK J.B.
Haha. Thanks bud. sounds like a solid fleet
I usually braze cast iron, less chance of it breaking, but if I need the strength of welding and don't care how it looks nomacast rods have always worked for me. Nickel 99 is a close second, but at ~$4/rod it's a little pricey to play with.
The important part is to get that sucker hot before you start and cool it as slowly as you can. Usually I bury it in a burn pile and fish it out a couple days later after it's done burning.
Good enough
Yes,you are a Hack,but I think that's why the majority of us watch you.I think everyone can always use a new hack to repair something...👍👍
Haha. Thanks bud!
Can weld using pure silver rods
way too expensive to braze such poor quaality cast iron but it is very useful to recuperate mechanical parts that have been broken and the fascia of the crack is completely reachable, just flux the fascia of the crack, clamp tightly the broken parts together to have a hairline crack then flow high silver rod as easyflo 45. I saved many parts that way without having to remachine to rmake them usable.
I doupt that brazing will resist as an exhaust manifold can reach red hot temperatures and the main reason for cracking is the contraction / expansion cycles and often a sloppy design as this log style manifold.
The old slant sixes exhaust manifolds cracked all the time
All that power

Pasta salad for the win! But my name is Salvatore and my last name ends in a vowel so ofcourse, right? 😂 dirty old farmers welds are some of the best, so i say you're good to go bud 👍
And ofcourse, 🐻⬇️
