Having finally got doors and walls on my workshop, I decided it was time to try and add a bit of heat. It has been a tad nippy of late - you may have noticed - so this was quite a priority!
Anyway, the basic idea is to turn an old propane bottle into a wood burner. This is not a new idea, and I thank those whose designs I copied or at least took ideas from.
So here are a few build pics:
I wanted a flat top to the stove, so first I chopped the top off:
Note, this cylinder had been venting for several weeks, upside down, and was purged two or 3 times with water before I attempted to cut it. It was also full of water while I was cutting it. The cylinder itself is ancient, and no longer a standard size, so only fit for scrap I believe (just in case any calor police are reading... )
Having emptied it, and provided a decent vent, I chopped a hole in the side:
then added a hinge to the bit I chopped off:
I put a chimney outlet in the back:
The idea of the chimney being a bit further down the back was to try and create a hot area at the top, before all the smoke disappeared out the chimney.
I also cut a hole in the bottom:
and built a simple control valve to be able to vary the air going in:
I also added some legs, and some strip round the door:
Next I cut out a circle of 6mm plate for the top with the plasma cutter:
and stuck it on:
I had planned to just have a solid top, but since I plan to burn mostly waste wood, I wanted to be able to poke long bits in as required. This meant I had to cut a section off the disc, so that I could have a removable section:
I added a grate in the bottom:
This is in 2 halfs so it can be removed for cleaning, and just rests on the bead that joins the cylinder to the end cap. It is made from 12mm square bar.
Next I put it in place and installed some stainless flexible flue piping as chimney:
This continues up the outside of the building for a while and has a cover over the end to stop any prevailing weather getting down it...
So all that was left was to set light to it and enjoy the cosy warmth....
Thought some people might like to see it being built. It has been covered before on here by simonr I and several others I think, but another one never hurts. It is not especially pretty, and the welding is pretty rough and ready, but so long as it allows me stay slightly warmer while I am working, it doesn't matter..
Cheers
