JABOD esc forge

[Cappygold]

So I basically designed this off of a JABOD forge but used a high heat fireclay as the base foot the mix.  It ended up being mostly a mix of 2:1:1 fireclay to sand to perlite.  I used Portland cement and more sand for the layer past the 'fire pot' because I needed more volume.  Also reinforced the edges or crumbling bits with store bought Hercules heavy body sodium silicate which works like a charm for those curious.  I used lump charcoal and it got decently hot but threw Sparks like a xxxx.  Currently working on an insulating and spark trapping dome.

 Looks like way to much air......work on air control and the sparks will take care of themselves . Just my thoughts.       Dave

@Dave51B how would you recommend that, I will be basically sealing the thing in with a dome/air hangar looking structure of steel sheet and the sodium silicate refractory.  Is the blow dryer to much potentially

[Dave51B]

 Basically, Either add a gate valve or just point the hair drier at the air supply tube. Charcoal needs very little air supply. There should be plenty of info on the site about this very thing.....        enjoy the ride                    Dave

Blow driers are generally too much for coal forges and charcoal needs a lighter touch.  It will always throw off more sparks; especially if the charcoal is damp; but controlling the air will help a LOT!

When I first built my own JABOD, I also built a homemade gate valve out of pallet wood. There's a pic-heavy thread  documenting its construction; check it out.

Simple air gate I use

FYI that's an electrical conduit body, they are properly called a 2" LB.

I leVe a gap on my wood fueled forge, a "T"and a ball valve on the mark II JABOD forge and a double acting bed pump on the mark I. You have way much air there, 10-30% clay and 70-90% sand would be just fine and way cheeaper
