Hi folks,
My new workshop is steel with insulated walls and anti condensation coating. I do have a fire extinguisher and cautious attitude with the brazing hearth, but properly should have a flame and heat resistant panel behind the hearth. Also, an oil resistant panel behind machines. What suggestions do you have?
Thanks, Dave

Hi Dave.
I would suggest you definitely need fire resistant insulation behind the hearth, at least 2 feet higher, and extending about 1 foot either side, for safety. We all forget what we are doing sometimes and wave the lighted torch about!!
If you can add a timed storage heater to come on during Economy 7 time, for a couple of hours at night, it costs very little and with fully insulated walls ceiling and floor (don't forget the floor loses 60% of your heat), you will have an almost constant temperature all year around and prevent any rust forming. An oil resistant panel behind the lathe is a good idea but you don't really need one behind a milling machine. As far as the floor goes, a vinyl floor covering is not a bad idea. It helps with keeping the floor clean, which in turn helps find small items dropped on the floor.
Bob.

I would suggest you also look at the ceiling immediately above the hearth. It's amazing how much heat travels upwards, and if the ceiling is flammable, it could easily catch fire.
Personally, my hearth is light enough (just) that I can take it outside to do any silver soldering. Apart from avoiding setting fire to the workshop, the flame gives off too much moisture, and the last thing I want is rusty machinery.

Very good point Steve.
I hadn't thought of that because my ceiling is 6' above my hearth which is also against the plain, brick, outside wall. I generally manage to keep moisture out of my workshop because it is built inside two thirds the double garage and has almost nothing liquid in it. What is there is in containers. The other 1/3 of the garage houses the garden equipment and the hearth, compressor, bead blasting cabinet, and bandsaw. I hardly ever use suds these days either.
