i welded this forge myself from scrap steel i had laying around, the ash dump is a little big so you have to really crank on the blower, but it get's plenty hot and really burns coal efficiantly.

could someone critique my work? tell me what i have done rightand what i have done wrong? and also sorry for the large pic size

It will work but the cutouts in the side may be a bit too low as you will have to build up the fire to get the necessary depth. I do this in the rivet forge just by filling it with coal and pushing it in to the fire as needed. If this is the case do what I did and weld a couple of strips into the cutout at the correct level once you have used the forge a fewe times. This may be made a bit "worse" if you end up lining for forge with some clay, while it helps shape the base of the fire pot it also raises the fire level.

The tuyere will work but I find a few bars of rebar welded in rows works better than holes in a plate. I found just holes get clogged too easily.

The size of your ash dump should not matter to your air volume. Just seal it up and the air only have one way to go. Better too large than too small.

Consider welding a couple of bits of pipe on one side at the cut out so you can mount a frame for long pieces to lay on while heating.

All up, a functional forge from bits 'n pieces.

Cheers

yep, rob browne covered it, but hey,...its only gotta work for my money....lol
