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.
You can also use dry sand to cool cast iron just bury it in it let it cool overnight
If they hold there gold! I'm going to use that one.
Should be just fine Doug! Good job!
The old slant sixes exhaust manifolds cracked all the time
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.
