Model Forum / General / Models / August 2006Gas fire salvage
We had our old "open coal" gas fire replaced yesterday and I salvaged the fireproof material that formed the fire tray. I tried the propane torch on this stuff and its not only got fantastic insulating properties but it reflects back an enormous amount of heat. So much so I could get a piece of inch bar to red heat pretty quickly, so now I have a little brazing hearth! Steve You can still buy fire bricks for hearths. I have used them for years as a brazing hearth. 1' x 1' and 2' x 2' bricks by about 1" thick can make quite a few combinations of sizes. If you make copper boilers they are ideal. For that quick small job I just lay a 1' x 1' brick on top of the vice with the jaws open to give stability. Alan > You can still buy fire bricks for hearths.

I used the lower half of a "fire back" for several years. The two part fire backs are split but mould as a pair. Sometimes one half gets damaged in the shop, and the other half is then scrap. Brian Another useful thing to salvage is the little piezo spark units that some gas fires have for lighting them. Dad found one in an old super ser he was raiding for sheet metal and fitted it into the toolbox on his oxy-ace bottle trolley. Really handy for lighting the torch (had an old lucas mag before that, and an ancient horseshoe one before that - Dad never throws anything away!) I was going to fit one but found a BOC economiser kit in a car boot sale for 50p!

I didn't bother with the piezo ignitor, got a piezo torch lighter for 50p at the petrol station! Steve |
