Repairing a Cracked body on a user plane.

Just bumping the topic…

The Handplane Book, pag 252, shows some repaired planes and gives some tips about repairs (. Planes that I have seen with repairs have a yellow welding, Oxy-Acetylene Welding. I would suggest to take the casting with a welder, he knows the best type of welding for this case.

Try J B Weld. If its just a crack you should be able to fix it with that. Home Depot

A pretty much invisible repair can be done with silver brazing. Very strong(same thing used to put carbide tips on saw blades). Tricky to do for a novice but commonly used by Jewelers, specialized Metalsmiths, Silversmith’s, etc. Requires Oxy/acetylene torch. Will be the best method of minimum to no distortion by a qualified person. Will fill a very minute crack and be invisible. Not to be confused with standard brazing or welding techniques. Superb repairs are possible to cracked planes. Anything else will look like a repair or worse. There’s no way JB weld can compare.
Most welders won’t have a clue about silver brazing. Silver brazing is a finesse technique.

-- Whatever!

Silver brazing would be best, capilary action does wonders to ensure everything is covered.

2nd best option would be brass brazing IMO. Tig is way too hot for something this size and I don’t think MIG has anything with a high enough nickel content to work well with cast, warping would also be an issue. With brazing you don’t go near the bad temps.
