Hi Jerry - What you are doing does work very well. Back in the middle 1940’s I invented the Nickel brazing filler metals based on the boron containing Colmonoy surfacing alloys. The original brazing filler metal was Nicrobraz 125, (BNi-1, AMS 4775). Now there is a series of the Nicrobraz Brazing filler metals.
Wall Colmonoy Corp. is a manufacturer of the nickel base surfacing filler metals specifically for surfacing. The materials are available in various hardness depending on the application requirements.
One of the original developments was the Colmonoy Spraywelder which sprays melted powder on a part with a subsequent torch or furnace fusing operation to obtain a smooth uniform surface which is metallurgically bonded to the base meats. On a round surface for example it finishes so smooth that it can be readily lathe machined. Visit www.wallcolmonoy.com for additional Colmonoy or brazing information. I think this is what you are looking for, a smooth putting on tool.
