Topic: Brass on cam

[tractorman]

Hey everyone, I know a guy who said that he can grind a cam on a lathe but he doesnt use a tig welder he says he uses brass. He melts a glob of brass on the cam and then cuts it. Is this even possible or is he just lying?

Thanks

Yep! Except you don't use pure brass, you use a nickel alloy.

[tractorman]

Mowdak 1 can you get this for a stick welder or a mig?

Its braising rod isn't it? Just comes in a stick and you melt it with a setaline torch.

[mowmaster]

Yes, it is filler rod for acetelyne-gas welding.
You can get it at a welding supply, or tractor supply @ mytsc.com

You can get nickel alloy for anything. It's typically used for hard surfacing anything subjected to extreme wear... i.e. the buckets on loaders, backhoes, scrapers. Just tell your welding supply store what you're doing with it they should be able to steer you in the right direction.

Wait are we talking about brazing rod or are you guys talking about some thing els?

[Squidd]

Yes..!!!

Allright thanks squidd I wasn't sure. My dad had said the same thing because I wanted to take a few 3.5 Flatt head motors and play with the cams a little bit and do some other work just to get the hang of modding motors. And he said to use that on the cam and I didn't think it would be hard enough but I will half to give it a shot once I get my hands on one or two small push mower engines.

It seams to me that years ago I saw demonstration where this guy had a blow torch and it had brass in the flam. When it was applied to a piece of metal stock in a lathe it would increase in size. Then he could machine it down. Has anybody ever heard of this? This was something new 25 years ago and I haven't heard of or seen it since.

What about the hardening/surface buildup rods for a stick welder?

[tractorman]

I called the guy that my dad know who does this and he says go get the nickel-alloy and melt it on the cam then take the lathe put the dial caliper on it and cut it to your designated lift

You still have to hand shape or grind the ramps (the transition between the base circle and the high point).
