CS cylinder repair

(1/4) > >>

olNick:
Hi all,

This cylinder is from my early 10/2 that I've finally started work on.
There is a fairly deep (~2mm) ridge from water damage I'm guessing. The ridge is about 5 inches down the bore.

While I know about re-sleeving, could this ridge be brazed with bronze or brass? and then bored and honed to size.
Cook the cylinder on the BBQ and the braze...

I'd like to keep the chrome on the cylinder as much as possible. The other cylinder seems to be fine.

I would also think that 5 inches down the bore the is minimal combustion pressure, temp as, IIRC, the power stroke ends at about 50* in a 4 stroke...

I am also contacting a firm here that can spray the ID and finish to size..
They say they can spray whatever metal is desired (e.g. chrome based) etc...

regards,
nick
PS This will be a working machine

I would not pick dis-similar metals, I think they'd heat unevenly and the union would fail, wear unevenly (and you'd be back to your groove) or fail spectacularly and you'd have chunks of brass out your exhaust and a piston go sideways on ya.

Spray welding sounds like the exact thing. Never done it with chrome powder, but if the pros say it can work, I'd trust it can work.

When I was doing spray welding (Iron moulds for glass) we would do it on cold stock, and just heat the area we were building up with a very fine flame.

No,  it wont work, the cylinder would be so far out of round when you got done brazing or any kind of  welding that would be worthless, but there is no need to take my word for it weld her up. It's no good now so you won't be ruining a cherry

if enough ice formed to deform the cyl, I'd mag flux it to look for any micro cracks before repairing.

Have you done this before?

We were held to some pretty tight tolerances on mould repair, and after machining you wouldn't know we'd even been there.
