Used a diamond blade on a table saw, cut at least 50 firebrick, then tile, then concrete block, brick, the 6.5 inch (16.5cm) saw blade is worn but still cuts good. Have years of use on it, worry more about the dust from the cutting getting into the unsealed bearings and killing the old saw! Never cooled it with water just dry cuts, always outdoors with an N95.

I think the problem might have been more the firebricks than the diamond disk, the ones available here seem to have a lot of iron slag in them, you get some sparks even when cutting them with a normal 4" grinder stone cutting disk.

Any half decent diamond blades should last for dozens if not hundreds of cuts !

I have no idea onthe composition of these bricks. They came out of a 22' kettle that was used to cook gypum into stucco. The burner was 70 million btu natural gas. I retired from the plant 2 years ago and managed to leave with 2 skids of them.
They make lots of spark.
I cut 5 of them for the bottom of the bell. I doubt if I can get another 5 out of the first disc. Cutting wet really helped but a little hard to do with the angle grinder.
No stove work today I am in ham smoking mode. we are having our Family Christmas today. Just wentback to the bush and got some nice hickory to use for a half hour smoke before putting itin the cast iron dutch oven over coals....gotta love that smoke

They should be really good quality then. Soaking them overnight submerged in a bucket of water really helps cut down on the dust.

Well done Tom, I was wondering what was happening with your build. It's looking great. What's on the top?
Neoceram is OK, Robax is slightly better on the afterburner, but on the stove door you wont notice any difference. I paid 50 euro for a similar size piece here recently.

Hey Trev, yeah I have been pretty slow atgetting back on the stove work. Still doing lots of reading on here though
I was at the stop the communism rallies here then I got sidetracked with biochar. I have made some really nice stuff out of
an elephant grass that is grown nearby I made a couple of tluds and I have a retort system half made
Lets face it...I'm just copying yours. The top has a 1/2" subframe the a piece of 3/8" plate
and I will be adding 1/2" plate on the bottom the way you did.
Hehe nothing original here
Tom

Thanks trev, I am hoping to get to a pottery supply place on Friday. They have the ifb and vermiculite board. Wow that stuff aintcheap Bricks are 9 to 11 bucks and the vermiculite boardis 11 dollars a sq ft. Not sure where you are located but in the USA harbison walker has locations in most larger cities that sell refractory supplies for quite a bit less than that. If you're in the east and not super far from Georgia I can't recommend Larkin refractory highly enough. Great people and great prices. No one that I have found will ship ifb or board products any way except freight as they are easily damaged. |
