Did my first potmetal repair

I had to repair the mascot for the '35 Buick She had broke off at the thin leg.
I used the Muzzy super alloy 1.
I used a O tip on the torch. A bit too much heat. I will stick with a propane torch with mapp gas.

Neat stuff to work with

I would love to master that. i have heard so many mixed reviews on the alloy rods. You could do tutorial. We would be glad to follow along!

I will try a 000 tip on my torch. The problem is that the base for the flying lady is thin and the lady its self is solid and holds the heat. Pot metal will melt at 750* and the super alloy at 350*.

I had a problem with holding the lady straight and up-right. I used two 3" C-clamps and two pieces of wood to sandwich her in the right spot.

One thing to watch out for is when to stop futzing with the project. I had her in the right spot and over heated the total mass and off came the alloy. The job did not come out quite right the second try.

I need to add more metal to the calf of the leg. I have heard that one can heat it up and it becomes soft and some adjustments can be made.

It would be best to use a welding heat sink paste to suck up excess heat.
On a flat item to fix use a 2x4 for a base to work on and a propane torch to keep the heat low. I will play with the oxy / acetylene rig just for S&G.

Are those the rods that you use a stainless wire brush to clean the metal with and use a propane torch to weld ? I bought some of those at a flea market and they really worked .The guy was welding aluminum beercans together and a few carburators.I had some pretty good luck using them on pot metal fender extentions.....

The kit came with liquid flux that you heat until it looks like honey. At that time you apply the rod to the pot metal. You tube has a vid on the process
from Muzzy.

Just watch the heat. I have been welding (TIG & MIG) for 40 years on all projects. Feel sorry for the Mrs. when I check out. She will have to deal with all of my crap in the shop.

That is cool that you can save a potmetal part.

As for leaving a mess, many of us have too much stuff that our other halves will need to deal with. I have 2,000 sq ft shop with parts stacked on pallet racking to the 16ft ceiling. Fortunately, my wife knows how to operate the forklift to get it down and "dispose" of it all...

Yes, I have too many projects and no time to finish some. The other half loves to add her projects to my work load.
I am still working on my weasel. Need to pull rear end and do steering bands.
Then pull the engine and trans just replace the starter drive.

1935 Buick:
I have been working on the rear drivers side door doing the wood repair. I picked up oak t&g flooring and other pieces of oak from Habitat for Humanity
at good scrap prices.
The glue I use is Gorilla brand from HF. Really good wood glue for the exterior
use. I will take pics. of repair.

OMG you taught your wife how to use the fork lift?????? if my wife had a forklift and a dump truck it would be all over for me...The only reason she keeps me around is the hope that some day I will get around to cleaning the garage so SHE wont have too.
