Cast iron surface repair
Is there anything better than JB Weld for repairing gasket surfaces on cast iron water jacket parts ?
Surfaces are severely pitted and need to be rebuilt, then filed/sanded to a gasket smooth surface.
Also have some aluminum radiator parts to do as well.
What have you actually used - and worked, or not worked ?
Only want to do this once.

Re: Cast iron surface repair
Cast iron CAN be welded. Used to be it was just a stick welding option, but TIG
can be used now too.

More people are doing it today than ever before !

Re: Cast iron surface repair
Yes I know, I have welded the cracks, but need to repair long areas of corrosion at the mating surfaces.

Re: Cast iron surface repair
Not that doing build-up and resurfacing is any fun at all, but I presume it is possible (?)

Re: Cast iron surface repair
The casting will seriously crack with that amount of heat.

Re: Cast iron surface repair
On some antique tractor cast iron gasket surfaces for the radiator tanks, I've used "Lab-Metal", which is an aluminum paste. I'ts like JB weld, but comes in a can. No hardner needed, as it reacts to air. It holds well, files and sands like metal and is good to over 400 degrees, as you can use it to fill pits and it will hold up to the heat in powder coating. So far, repairs I've done several years ago have held up fine with no water weeping or problem. You can look up "Lab-Metal" on line.

I used this (aluminum type) to build up, drill and tap a hole in a chainsaw exhaust mount...still holding
It's made for steel and aluminum, but different powders.

Re: Cast iron surface repair
Not too long ago I posted a link to a youtube video where a man was laser welding the rust pits on a gun to restore the surface to a smooth finish.
Perhaps someone can find the thread and bring it here for you to see.

Re: Cast iron surface repair
Thanks for the suggestions.
Looks like the Lab-Metal might work better for resurfacing. Will order some and give it a try.
(Boy do I wish parts were available for Mack’s like they are for T’s )

Re: Cast iron surface repair
I have used JB Weld to repair corrosion pitting in an M37B1 military Dodge and it held up fine. The stuff is almost bullet proof.

Re: Cast iron surface repair
Google Belzona. It is an incredible metal repair. We used it to reattach the water inlet elbow to the engine block on my 14 T. This was a couple years ago at least. Has held up with all the heating and cool-downs.
I still have some in the garage and can get you more info on it when I get home.
Lemme know.

Re: Cast iron surface repair
Looks interesting.. trying to get more info on it, but takes ‘authorization’ to view availability and cost. So, waiting on approval.Marty Bufalini wrote: ↑Sun Oct 27, 2019 11:29 amGoogle Belzona.

I have a cast water jacket cover that is seriously corroded that would benefit from it, if it can build up a large complex casting from the inside.
If my short term memory gets any shorter, I won’t even have thought about what I’m going to forget.

Re: Cast iron surface repair
Taking a very small rotary file on a die grinder cleaning out any corrosion is of utmost importance too. If you have an outside casting repair and you wish to regain the appearance of cast iron, try this trick. From a distance spray lightly, "lightly" some Dupli-color spray on bed liner fogging into the good area. Be prepared to be amazed. Only your Mother will know.
All the Best,
Hank
