Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

Jensen doesn't use silver brazing solder for these , a Good high temp solder is sufficient, it can be done without losing the nickel plating, if you don't over heat it , both end caps should be removed & I use the appropriate size drill bits to use in the valve steam passages for perfect alignment(just don't solder them in place) Indianarog has a good tutorial on this.
