Thanks for the kind words guy's.

To buy or build a boiler. That is the next question.?

I have done quite a bit of soft soldering over the years but the skill of silver soldering and the required equipment is something I possess neither of. - Is jumping in a the deep end of making a boiler a good place to start to learn this skill I am wondering.?

Any advice will be welcome.

Many thanks again, Nick

In my, albeit limited, experience silver soldering is not difficult. It requires scrupulous cleanliness in the joint areas and a reasonably close fit of the components to be soldered. Heat to get the component parts warm and a little extra heat applied to the cleaned and fluxed joints when applying the solder to get it to run. Sure, have a practice on some scrap copper sheet first and you will see how easy it is and will quickly gain confidence. Good fitting joints are needed - you don't want to try filling holes and gaps with silver solder and, just to reiterate, cleanliness is vital.

Apart from the method and amount of heat required I don't think it's much more difficult than soft soldering.

I do like the James Coombes and my current project of the " Trapezium Connecting Rod Engine" is similar in many respects - I may actually finish it one day !

Regards

Norman

Another thread had prompted me to make this post after all this time. surprise

Although I have another project 'on-the-go' presently. (which I have neglected this last couple of months) I do think a 2 X scale of the James Coombes on the size of and perhaps using the cylinder etc. of the major beam would be a most impressive model.

Would require the fabrication of the base, flywheel and the cross head guides, but certainly 'do-able'. yes

Only issue for me would be that my lathe can only turn 10 1/2" so flywheel would be a problem without using my friends lathe.
