Object is a nickel plated 2 stroke exhaust pipe. I need to close up a
small crack before I can blow out other "dents". What issues will I
run into? Do I need to grind off the plating?

I can't help you but how do you 'blow out' dents?

Thanks

Plug both ends, the fitting on the big end will accept a regulated air
supply from my compressor, put about 20-30 psi into the pipe, heat
affected area with O/A torch, the dent comes out. Move on to the next
ding...

This is the inlet end plug. I safety wire this to the spring mount
loops:

I safety wire a small expansion plug in the exhaust end.

Ooooh, what's the copper fitting that the airline adaptor goes into? Is it
a custom made job or a commercially available part?

Cheers

David,
I just clean it well (burn it and brush it) first, and then
oxy-acetylene them with a filler rod.

I don't use the air regulator, so I sometimes find fractures and
cracks as the heat and pressure build.

I also don't worry about the color of the chrome.

1.5 more weeks till I can ride again.

1.) I'll bet it is chrome plated, not nickel.

2.) If the crack is not too close to the dents you are going to blow out, I
would silver solder or braze it. You won't burn away as much plating, and
can probably polish it afterwards so it doesn't show.

Not that it really matters in this instance, but I've always thought
the "chrome" was simply the transparent, glossy "clear coat" over a
base plating of nickel. These plated pipes may have skipped the chrome
layer. If there is a chrome layer, it's not a good one, very little
gloss. I have seem chromed dirt bike pipes, very different appearance
to them.

One brand of bike (GasGas) nickel plates their frames.

2.) If the crack is not too close to the dents you are going to
blow out, I would silver solder or braze it. You won't burn away as
much plating, and can probably polish it afterwards so it doesn't
show.

I'm not too worried about appearance, the heating during the blow out
process is going to ruin the plating around the dents anyway.

Hey, it's only a dirt bike, not like I'm out with the Hardly Ableson
Chrome & Leather Crowd. <G
