I have had a recent run of orders for large items, much larger than my 35cm long forge. So I built a longer 65cm version. I kept the diameter smaller so it would still only use one burner and keep the steel hot. I tried a different option tried with the back door that allows a future extension to be attached on later. It fired up nice and hot with not much effort. I think it will run at a similar pressure than the larger, shorter forge.
I tried a new idea for the handle - welding on some chain. It has a good feel when carrying the forge.
The forge has be affectionately dubbed "long pig" to go with the existing "little pig" and "fat pig".
