Hello all,
Well I've been workin on the Bowser Northern. Should have it completely done by December.
I had to rework the boiler walkway's to fit the pump for the Worthington heater. Lot's of bending. I am afraid of work hardening the walkways. Seems to me that I remember heating to a dull red and quenching in cold water to make dead soft. But, that was ten years or more ago.
Anybody else know?

Thanks
Benz

Basically you are correct though brass can be subjected to various annealing temperatures but you just need to be close. Bottom line dull red or even bright red will work. Then immediately plunge it into cold water.

Hope this isn't a dumb question , but I'll ask ...do you simply heat it with a propane torch ?

Yes a propane torch should do it Terry. Most MRR items should be fine.

Unless you're trying to anneal a solid brass O-gauge boiler.

Benz,

There is an interesting paragraph on the Ngineering website. At the bottom of the page on “Tubing Bending” is a note about Annealing. Maybe it will be of interest. Here is the link to that page & their website: http://www.ngineering.com/tubing_annealing.htm
