dancho Posted July 27, 2012 Share Posted July 27, 2012 My latest design of side blast ceramic forge. I cannot think of any better device for working on char coal so far. Perfect for welding. Less air and coal – ok for small objects like knives. More air and coal good for heating billets 3 kg and 50 mm in diameter. Made on basin base 55 cm in diameter. Material is fire clay mixed with shamot(burned and crushed clay) about 1:1 and then mixed with plenty of small cut hey for reinforcement. After burning away the pores act as insulator while clay is heat accumulator. The blast pipe is 40 mm diameter forged on the end to give conic shape. The fan is from old tractor stove. Consumes 30 Watts at 12 volts (for maximum output). Less for smaller (about 20 Watts). Works from my off-grid electric system (micrhydro and PV panels).

ThomasPowers Posted July 27, 2012 Share Posted July 27, 2012 Looks a lot like one of my Y1K forges; save that mine are blown by twinned single action bellows. Quote Link to comment Share on other sites More sharing options...

I like them too but blower make me looking a little bit more up to date. Was blamed for too long as being a "retrograd" and "historical reconstructor". But bellows are magic. They are alive and create rhytm. It is important. Quote Link to comment Share on other sites More sharing options...
