So I've only run this the once yesterday, and it was cold here, alternating snow and sunshine anywhere from 0-10 degrees C (32F-50F).
I got it up to around 225, and it didn't stay there for long, dropping off until I took the lid off, and then spiking up fast.
I've got to put the ball controls back on but I only painted it yesterday and did my burn in to seal the paint.
The pipes are 22mm (3/4 inch)
I woke up this morning went to have a look and the barrel was cold to the touch, I only used half a basket full, and opened it to find unburned coals, and a small set of embers. I've taken the lid off now and it's burning well, enough to cook some bacon on...yeah I stopped for breakfast before posting.
My main question and I think I know the answer, do I have enough air? I'm thinking I probably don't. Tempted to put one hole/pipe in at the bottom with no riser and leave it uncapped.
ADDITIONAL INFO: Got some ribs on now, I'm only using a crappy old thermostat that is dropped in via the air vent but it won't stay hot, so lid off for a couple of mins, smoke going etc. pretty sure it's lack of air now, debating 2 more intakes no valves at the bottom, and keep the 2 with controls on as, well, controls. It burns away at 210 ish and then drops, when I open the lid it is obviously suffocating the fire.
This last one was this morning ten minutes after the lid was off!
