Here's mine. Three combine wheels, welded together. Fordson major flywheel on jack underneth for airflow and cleaning out.

It holds about 5 dustbins of woodchips at a time. We don't get cold

I made up something like this a few years ago , I used a Large propane cylinder (empty of course) wth a small hatch near the bottom , a flue on the top and a drip waste oil feed fed from a ford cargo fuel tank , Used a bit of rag to start it and regulated heat by oil fed through a ball valve .

It worked a treat ,The cylinder used to glow red , Only thing was I made it for work and the HSE set eyes on it and went absolutly mental.

Steve Im jealous - epic bit of kit. think they might get a bit upset if I pinch the wheels of the MB though big prop tank is a good idea Ciderman - mind if I blag that one?

A bit like this one ciderman, i made for my garage








TWIZZLE

Years ago (in a previous life) a mate had one made from a tubular lamp-post. The upper part was about 4" dia and formed the flue, the lower bit bulged out to maybe 12" dia and had a ready made hatch. Similarly to the above we fueled it with a drip feed waste oil (with a couple of pre-heater loops). Our addition to the concept is that we had a compressed air feed just above the hatch pointing tangentially and a little up the flue (so I guess that's helically then). With a small amount of air on the whole thing would roar and resonate and glow up the flue like a pulse jet, and would issue several feet of blue flame from the top! Once it was warmed up there was very little smoke and we decided that we were being 'green' by recycling the oil and saving on electricity...

very simular , where the cylinder tapers up to the handle , thats where the flue sat 6" steel pipe, It used to fill the yard with smoke at first but after 10 mins it burned clean , and with a fleet of over 70 hgvs and plant we had LOADS of waste oil to burn.

I used to have a waste oil drip but a Council man got quite shirty about it

A bit of air in the bottom certainly livens things up.

The main advantage with a bit of size is that you have less work chopping wood. We burn a combination of unwanted wood from a tree surgeon and chopped ex skip wood.
