All good points and slowly I'm going to upgrade until have the money to build separate forges for knifes and then one for casting but this was also my first forge so for a start it's not bad and I keep safety at the first priority even if the forge itself is not entirely that but I am very careful with anything but thank you for the feedback! @Frosty

Frosty thank you for the feedback! 

I did find many things wrong with his design so I tweeked it a little and used it once yesterday but I changed the torch completely today to some better specs and it works much better and is just running off of propane. I did cut the combustion tube back about 4 inches as well which helped tremendously and I can melt things much better. Also I decided to not use galvanized steel because like you said it's super unstable and unsafe if you heat it up enough so I just used steel for the first gas mixer but since this I don't even use that due to my ability to get more heat without the compressed air now! Thank you for your comment though and Happy Forging Sir!

iOk guys, so I changed a few things in the burner today and thanks to the help of you guy's comments I can melt aluminum extremely fast! I just would like to thank especially @Charles R. Stevens For the amount of time he spent helping me, being a newb in the business, and due to it the forge is achieving more than what I expected! Thanks guys and I will still take suggestions if anyone has something I would love to hear it! 

Well this design sucks air in from the base of the fire tube and burns the gas right after the mixing chamber so would it be more productive to cover that hole somehow that way the gas doesn't burn until it reaches the end of the tube or do I just need to cut the tube or what because I understand I'm loosing the heat in the tube but the design it has is made to burn in the tube so would it be better to cover the rear air colum in the back of the tube I guess? @swedefiddle

I would like to be able to achieve both with different heats in the furnace to forge knifes but mainly for casting as of right now and the design that I acquired has the main burn inside of the tube but would it be more productive to cut it off more so you get the majority of the flame in the forge it's self. @swedefiddle

Also it may be too late but is it going to be bad to put the blanket around the clamor because I have already(stupidly) put the ceramic in the forge and would rather not have to scrape it off and then buy it again so could I just use the blanket with the reflective coating and what was the ( ridgidizer)?? Where can you get that and what is it?

Thank you so much for the help sir! Happy forging! @Charles R. Stevens

Ok do you suggest any particular brad of either of these I'm pretty new into the gas forging world so I don't know much about it and I would take all the helpful suggestions I can get!

Ok so would like the kaowool work for that I guess? @Charles R. Stevens

The burner is a jet torch with compressed air and propane so it burns inside of the fire tube. If that's what your suggesting? @Charles R. Stevens

I'm insulating it with the refractory cement  and I don't know why the pic did this but it is blue actually @Charles R. Stevens

So I just build my first propane forge and got it going pretty well and it will barely melt aluminum in my crucible but the design should put out more than what I'm getting any suggestions on what I could do to get more heat besides keeping the gas around 7 psi and pulling the burner tip back around 3/4 of an inch! Anything would help!
