Any photos Darrenyou do a bit smithing ?...
I thought I had a build post on here but I couldn't find it, so perhaps it is elsewhere. I don't actually do any smithing but there are times that I have needed something heating to bend or annealing and it's either too big for the oxy (or too expensive more to the point) and I haven't built my furnace yet, so annealing would be problematic. Also, I've used it to melt aluminium and lead.
It started out as an old split rim wheel that was sitting in my junk pile and is cobbled out of scrap and was a process of trial and error in terms of getting the air right. First attempt shot hot coals in the air
I use mainly scrap hardwood that I get for free as fuel. Here are a few pics and if there is any interest, I could probably start a new thread with a bit more info and pics.Baffles over the stud holes direct air into the centre. Mesh stops hot bits falling and melting the vacuum hose and the cut outs allow long parts to be heated without fear of them rolling off.
Getting it up to temp slowly, waiting for the wood to break up a little. That is a hardened drill coupler in the middle waiting to be annealed.
A bit later in the process. I knew it was at the correct temp as my fridge magnet wouldn't stick to it. Well it did for a second before bursting into flames, melting and running off.
Into the ash bucket to be covered up and left to cool slowly.
A bit too much air
