Well folks, I have another boiler related question...
The steam engine is coming along and I'm ready to silver solder the frame so it's time to build a brazing hearth. Fire bricks are about $20 (Au) each here and CalSil is very expensive - about $30+ (Au) for a piece about 250 x 120 mm. Looking at Hebel blocks they're a lot cheaper but they're 'special order' at Bunnings, not kept in stock. The Q: Has anyone used Hebel blocks for a hearth and also does anyone know a stockist?

Hi Brooksey,
I made a small wedding/braizing box and lined it with Hebles from Bunnies. Never had any issues. Hope this helps. Cheers, Peter.

Don't know what you have in your area but I went to an 'artsy' type little pottery shop here in Perth and got super lightweight insulation bricks for about $6 each. Same shape and size as a normal brick but almost the weight of Styrofoam. I just keep them loose and arrange them into the shape I need as I need them.

Thanks fellas,
Good to know the Hebel is ok.
I'll be going through Brisbane tomorrow so I'll check around. The bigger Bunnings might stock it
