  1. After my first post / question above I made a deep dive into this forum and have seen many design errors with my forge There is a sliding valve after the blower, to be able to limit the air flow, however, air blast direction must be changed. I have seen that Japanese charcoal forge designs, tuyere pipe makes approximately 30 degrees angle downwards and connects the forge wall horizontally. As "Irondragon ForgeClay Works" mentions, charcoal size must be smaller. Wallnut-peanut size would be better. I've learned from the forum that the iron I'm trying to heat needs to mate not with the flame but with the charcoal itself. So smaller size is better, it means more surface contact. Answer to "Irondragon ForgeClay Works"'s question, air gate valve can be shut off completely as needed. It is an easy to operate valve and I shut it off just before working on anvil. And thanks your compliment for the forge. Charles, I'll completely change the design. As you said, air direction is so wrong for charcoal ( and especially charcoal that big) almost all the ash gone with the air. After burning around 20 kg's of charcoal in a batch, just a handful of ash piled in the ash gate And Ok, I forget that firebrick issue. At least bricks won't have a direct contact with the fire. I'll build the new pot with 10mm steel (3/8"). Deep enough to accommodate enough properly sized charcoal. Additionally find a speed controlled blower. Some designs reduce the tuyere pipe diameter by half where pipe just enters the pot, to increase the air speed. Would you recommend this? Thanks everyone for advices. BTW, 20kg of charcoal for forging/bending 54 pieces of holdfasts from 3/4" St-37 steel. I have no idea if this amount of charcoal is to much for this project.
  2. Hello Charles and everybody. I'm new to this forum and also new to blacksmithing. I've just had the same problem with my forge. I've designed it for coke assuming that finding coke is easy however could only find good quality coal (low sulphur) and maintaining an even fire with coal is another craft I don't have yet. Now I'm using my forge with charcoal (from red oak) and realize that the fire depth is not enough and as you mention tuyere at the bottom creates lots of fire fleas (hope we speak about the same thing). I have plenty of firebricks and refractory cement. Would it be a good idea to put two rows of brick around the fire pot (but keeping an access to fire) to deepen the forge? Or just build another forge from scratch? Thanks
