Mate is heavilly into Viking reenactment and needs a forge to make various items for himself and others. Seeing he's also a HGV 1 driver I told him to scrounge the biggest brake drum he can find on the mechanics scrap pile. Today he presented me with two huge items 
The plan is simple. Plates on both drums joined together with ungalved scaffolding size pipe so one drum forms a base. Inside the "base" will be a salvaged fan off a central heating boiler rather than the more normal hairdryer.
Question I have is about where the presurised air enters the bottom of the fire pit drum. Most pics I can see of other peoples forges show just a plate with holes flush with the bottom of the drum. Seeing I'm using thick walled pipe I'm wondering is it might be worth having it encroach into the fire, say, 50mm. The top would be capped off and holes drilled in that as well as around the exposed pipe. That means air would then come out of the sides as well as the top.
Is it worth doing that or would it be a waste of time and no benefit ?
Thanks.
