It's been kind of quiet here lately and I've not done much of anything worth breaking the silence over, but some time ago I began the fabrication of the smokebox saddle for my 2X TICH which I am building up with cut and milled pieces of 1/4" steel plate. I initially envisioned welding this assembly together but I am an aBYSmal welder so I caved in and decided to silver solder. This went well enough but I have a final piece of plate to add which could not be added until some machine work and hand shaping was done on the basic assembly, after which more machining and hand shaping would be done. This has raised a question. If I want to add the final piece by welding (and I'm not certain I will weld it), will the weld "take" as it passes through the soldered areas or will it not adhere? My guess is it will probably burn through as if it was a patch of oxide. Cheers, Harry wade Nashville USA Regards, Harry Wade Nashville Tennessee MODEL ENGINEERING DISCUSSION LIST.
