Hi Mozo
I was using a stihl saw to cut my bricks and used up a blade. Bought an erbauer one from screwfix as a replacement for about £30 and it has been fine. Mine was 300mm so yours would be a fair bit cheaper. One for £7.99 that looks about right.

Check out evolution rage sliding mitre saw. That's the one I used. One blade did the whole oven at 30 quid for the blade. Saw was on Deal for 50 quid. Good for other stuff as well.... Might be worth considering..... ESP at the rate your going w blades!!

I'm with bhuna on the sthill saw much safer than a cheap mite saw and made for the purpose plus a lot faster and they have a water inlet for a hose pope so dust free cutting cheap enough to hire but buy your own blade

Thats amazing! looks like some heavy duty work there. I also saw your build, looks incredible. I think the problem I had was that I didnt wet the bricks enough and I cut too fast ruining the blades prematurely. I bought a new blade yesterday and I have already done more bricks than previously! I was hoping to start mortaring in the first layer. Liam suggested I get some ready mix and I did just that. but it seems like my bricks will not be 3-5mm close at the outer edges. I bought some firelay from ebay (http://www.ebay.co.uk/itm/25KG-Bag-of-Fire-Clay-to-make-Refractory-Furnace-Kiln-/251212844260) to make my own homebrew, I thought it was just finely ground firebricks, this is not what this looks like at all... any ideas?

Thanks mozo glad you got the cutting sorted out. Yes that is fire clay not ground up fire brick they are 2 different things the fire clay is used as a plasticiser in the home brew making the mortar more pliable and not just drying out as soon as it hits the brick I dont think adding thistle Liam's pre mix will work for large joints the home brae which I never used is a 5 part mix I think Inc. sharp sand,lime, Portland cement ,fireclay and water this mix can stand the outer joint size. I opted for ground up firebrick which is called "grog" and I high heat cement called cement fondue. The home brew is a tried and tested method most use it

Lee's sorted your answer - I used fireclay from the same seller at a ratio of 6.1.1.1 - no problems at all.

Hi Mozo, how is the build going? I finished my brick base yesterday after almost being flooded the previous night. For cutting i went to Screwfix & bought the cheapest 9" angle grinder which was a Titan for £50 & a Erbauer Sintered Diamond Blade Segmented 230 x 2.5 x 22.23mm for £15. I was a bit concerned it would be difficult to manage and not be the right tool for the job, but is was wrong I have been able to easily cut bricks in half lengthways, curves & trapezoid. As suggested elsewhere the cutting is done using the weight of the grinder rather than trying to cut through, so ones energy and attention is on making the shape of the cut. If the rain holds off i will build my framing today & pour my hearth tomorrow once the brick mortar has dried.

If you are cutting fire bricks don't forget to use a stream of water from a hose to wash the dust away while you cut, i think the dust stops the blade from working, a mate of mine gave me the tip and my saw went through them really easily.

Thank you guys for all the advice, I have been going slicing the bricks nicely. Its even starting to take shape. Add AttachmentOne thing I am not looking forward to is the inner archway. It looks a bit tricky, but I will work on it this weekend.

Thanks Lee, I was hoping to taper that back, and making a simple upward slanted cut for the dome to rest on using a string marker. I think this will be far easier than cutting individual bricks to sit over the arch. Mozo ps, first figs look almost ready

quick question guys, the fire bricks seem to be getting a white colour every time they dry. I dont know if this is minerals exuding out or because they are covered in a thin layer of mortar.
Everytime i wet them they go back to their natural colour but they turn back quickly. has anyone had this issue before? how can I fix it?
thanks
mozo
