Aldi and Lidle have them also CRAPLINS but twice the price hear is one on Amazon, I use One for model work and it works fine, just get good solder and flux Peter

That is a very very very expensive way of buying 4 fire bricks. (3 sides & a floor) I would put that little lot on a non flammable surface.
I actually use paving bricks & a soldering mat:

but I might be better with one of these:

Whatever you decide to do DON'T solder on concrete as it can explode.

Just a thought but do you really need silver solder for railings? They are not exactly load bearing in a model.
If you do I would be interested to know why as I soft solder railings.

I have been soldering on wood for years , smoke everywhere, Neil suggested this on another forum got one never looked back no smoke alarms at 3am, plus you can stick parts in the base to hold them I have bought a slab of it for soft soldering so I don't contaminate the larger one with soft solder, for the price there great.
silver solder is my choice for some model parts mainly parts that can be bent or prop shafts BUT that is just the way I do it everyone has there own way of doing things

I have often soft soldered on wood with a soldering iron & I have also used a flame plus mat on occasion but it is less smelly with pavers.
I first found mats when I was refitting the kitchen & had to solder water pipes which were very near some plastic pipes that I really didn't want to replace. I was amazed how much heat I could put into the pre soldered fittings & not do anything to the plastic only an inch or so away by using the mat. It really does work.
I have always been given "engineering" silver solder but I am not sure that it has been to my advantage. I have had to use propane as butane doesn't get hot enough. I might stop being a cheepskate & buy some modelling silver solder with a lower melting point.

Hard or Silver Solders exhibit a much higher mechanical strength rating than the Tin/Lead versions which are normally used for electrical or Plumbing work.

PS., Plumbing work does not include steam connections.

as with soft (tin/lead) solder you can get different types that have a range of melting points, If you have very high melting point silver or hard solder it will be more difficult I use silver solder sheet, cut strips and use that or on fittings 0.6mm wire and good flux Johnson Matthey silver solder products http://www.pollymodelengineering.co.uk/sections/bruce-engineering/materials.asp

thanks for everyones advice

I have been using a small pencil torch called the MiniFlam for small fittings and railings. It has a laser-like flame and is very precise. There are no gas mixture knobs on the handle to get in the way. The gas tanks are residential and non-hazardous and can be used at public shows, also the tanks can be mailed through the post. I use my larger acetylene/oxygen torch for the larger materials. I also use a paste solder in a syringe. It is obtainable in silver solder or tin solder. It makes for less cleanup and filing. ;)
I have found a used MiniFlam torch on EBay for only $20.00. :-))

rich..just tab in vermiculite into ebay............you can buy the stuff much cheaper(There's a place where I live in Poulton le fylde that sells it.............superb stuff, cutable with a hand saw and brilliant......you can then build your own hearth to any shape you wish for each and every job you do.
