Cast Iron Welding

[Sport Scout]

Purchased a decent square base scout cylinder. It's only fault is one of the base stud holes has the outer half broken off. Any leads to find a well qualified welder to repair the stud hole? Willing to pay for quality.

It should be brazed, not welded

With all due respect,
(for after all, I do NOT offer the service...)

Cast iron can often (of course not always..) be flame-welded using piston rings for filler rod.

I guess you would have to see it to believe it.

PS: It works fantastic on Chief frames!

I'm not sayin' that another method won't work, but I've seen alot of weld failures, and harldly any braze failures.

We got a cylinder flange ear braze repaired on our class C race bike, and it's got 3500 miles of full throttle racing without failure.

I like to do what has been proven to work. Come to think of it, I do it for a living and nobody has ever seemed to complain of a failure..............ever.

Tom!

Most all true pro's that I know (who also laugh heartily at my piston ring filler of course) go straight to silicon bronze or nickel by TIG. Brass is a sin to them.

Both are extremely hard to work with, and far more trouble in the long run.

Cast iron on cast iron is machineable. That means a lot from a practical sense.

Another option that has worked well for me is silver solder. But then I didn't know any better.

Everything has its time and place.

A brass fix on a cast iron part won't get by the judges.

Cotton,

Dont' condecend to me, with "most true pros" Screw you, I'm not a pro?

You should consider that the comments you make, toward someone that others respect, may create hard feelings and hurt your buisness.....you seem to be good at that lately.

For 15 years now, I've been wanting to go to a Bud Redmond New Year's Day cast iron welding party. The method of the purists in my neighborhood will build an igloo-style oven out of fire brick, slowly bring the work up to 2000 degrees or so, then torch-weld in with cast iron rod, trying to maintain oven's effects til welding is complete, then let sweat in the oven for a while, then submerge in vermiculite, or floor-dry, and let things slow-cool there, which should be over 12 to 24 hours to get down to warm-to-touch. The concept with the heat is that even heating and slow cooling will yield the most even distribution of stress areas, and an even reaction to heat-and-cool growth for normal working.
I have friends who have brazed in wrist-pin gouges, and claim several thousand miles of service. Heated to 450 in the oven, .......

Dan Gesick did a wonderful job repairing 5 Knuckleheads for me. No visible repairs when he is done. UPS goes to his door.

Dear Tom,

When I wrote "With all due respect", I meant it.

And when I wrote "Most all true pro's that I know', it excluded you, and millions of others, ONLY because we have never met!

Please overcome your sudden Sergeant's Disease attitude and look at the penetration in the pic I attached.

If I can do it, anyone can.

Cast Iron Welding

Hi, I'm Chris. I don't post too much because I often only know enough to listen, but I'd like to share a link explaining a process for cast iron welding. Midwest Cylinder Head & Machine calls it "Oven Fusion Cast Iron Welding". The process is similar to what Phil described. http://www.youtube.com/watch?v=S7uZhpYH0wY

Never one to miss a chance to take a cheap shot, Tom Cotten, "Mister Non Sequitur" (look it up, Tom, it fits you to a 'Tee'), strikes again.
If you shriveled up and sank out of sight, you wouldn't be missed.

Back on topic,

Chris pointed out that brass would annoy the Judges;
I read that mid-'40 was the introduction of square-base Scout Cylinders (Hatfield), but it is unclear when production changed from nickel to enamel, if ever.

Enamel covers brass (silicon bronze, nickel rod, etc.) equally,
but do different metals take electroplate identically?
Electro-less?

I have the impression that they do not, but it may have only been a bad plating job.
