Hi All,

I have a Stewart speedometer swivel that broke on the knuckle that has the tapered pin as illustrated here. I don't have the money to buy a complete swivel for what they seem to be going for these days. Does anyone know how to fix pot metal. I've seen Muggy Weld on the internet. Or does anyone out there have a parts box with an unbroken knuckle they would sell me for cheap?

Many people would not agree. But I would clean it with lacquer thinner (really soaks oil out). Let it dry thoroughly. Use slow drying "two ton" epoxy. Because it dries slowly, it soaks in better to the crystallized old die cast metals. You probably wouldn't believe the '20s ignition/light switch I put back together some years ago. I wish I had photos of it before and after.
That is my hokey old opinion.

Wayne has a good suggestion about getting the oil out of a porous casting. I've seen guys braze pot metal successfully in the past and those repairs have held up to this day. Find a good welder or repair shop in your area to get an appraisal of the work. Should not be expensive at all.

Mark,

What is the number on your swivel? It looks like a Stewart #1962 which is a 6 to 1.

I have a bunch of partial swivels. Might have an extra housing half like that Mark. Send me a PM.

I checked and I have one.You can have it for the shipping costs. email me jackdaron@aol.com

Mark,

How/why did it break? If that happened during normal operation I would question what caused it. When gears get very worn they can climb over each other and want to push apart. Kind of looks like the output shaft housing wanted to exit the pot metal housing real bad and busted it up. I'd be sure that wasn't really the case before putting a new pot metal piece in there.
