Following on from the disposing of waste thread have being thinking about building a forced air burner, maybe from an old skip or some sort? would only need a bit of pipe welding and a fan as to create an air curtain...maybe something to stop the heat from mullering the steel :confused1:

The thought had crossed my mind after seeing them on you tube but as Mr skyhuck says it would turn into a big pond in no time.

There is nothing to them though, its just a steel box with some sort of fire brick in side with a load of air blasted over the top. Can pick up a skip for £200 just need a big fan of some sort.

I have seen the damage these burn boxes can do to external steelwork if the refractory lining fails, I nearly bought one that was advertised as needing repair but it was totally mullered. That fire with a blower on it makes furnace temperature and can easily melt steel so if your thinking of a skip you will need to make sure its well lined or you will end up with a twisted heap of steel plate.

 

Just thoughts but I am thinking of the hole in the ground because its easy to tip into. I was thinking along the lines of a ten foot square hole fenced off with four steel twelve foot five bar gates , one hinged opening for access and the other three bolted together to form a barrier ( dont want folk or animals falling in that :) ) If the water is a problem its not going to take much to engineer a simple sump in one corner for pumping out.

Good point there bob, suppose the only cost of a pit is going to be the fan.
