Hi Folks
Im a newbie to all this, though I have machining and welding experience, applied mostly to old motorcycle restoration. Ive been given about half of a Rob Roy 3.5 gauge 0-6-0 tank loco (a common Martin Evans design apparently suitable for a beginner...), and Im reading a lot and thinking about making a start.
Im thinking about the (copper - assembled with a mixture of silver solder and oxy-acet brazing) boiler, since the work so far on this has gone a long way but is a little non-standard. Ive had various suggestions along the lines of Id start again if I were you and although I may well do this, I dont like to be frightened of something Im working on, preferring to have a clear idea of what is what.
I've had a read around on these boards, and looked over the stickies at the top of this section.
So first question do Evanss Model Locomotive and Marine Boilers (Argus 1988) and Harriss Model Boilers and Boilermaking (MAP 1971) still give a fair impression of good practice, or have things changed? I have, and have read, both the former is particularly useful in containing a number of formulae to calculate barrel thickness and stay spacing, which Ive been comparing to the standard design but Im in no position to know if the information is considered current, or obsolete.
Thanks
Mark
