Buy a galvanized bucket from any builders providers, drill two rows of holes (5mm approx) for air intake, place the bucket on a concrete block or bricks (very hot, will damage grass, tiles etc) Have some sand to hand to put the fire out in emergency or when finished, get a firelog and place in the bucket and light (only one firelog at a time), do not move the bucket when lit as you will be roasted., not for use when children are around, keep the bucket away from any combustible materials, cost 15 euro.
Build your own BBQ
Buy a BBQ kit from any DIY store (read the instructions), buy 115 red bricks, a few bags of sand and a bag of cement, use the firetray as a template and place the first row of bricks around three sides and make sure everything fits, check the ground level, mix up 6 parts sand and 2 parts cement and add water. Add enough water to make the mix pliable. This is your mortar. Lay the first row of bricks, taking time to get it correct (the BBQ kit has detailed instructions), now continue laying the bricks making sure to overlap the joints, on the tenth layer four header bricks need to be put in on the two sides to support the oven check that the oven fits before proceeding), lay another layer, on the twelfth layer start putting in your brackets (two each side, the brackets have three cooking levels) The brackets are held by two layers of bricks, now finish your brickwork with a final top layer, clean the bricks as you go (wet sponge or brush) to remove any mortar stains, using the mortar, point up all the joints to make it nice and tidy, Finally check everything fits and remove all the BBQ parts, leave the mortar to dry for two days, now wish for good weather.
